The most excruciatingly simple answer is this: a neural net neuron is exactly like a nervous net neuron except that the capacitor and the resistor on the front end are swapped. The capacitor which 'normally' performs differentiation performs integration instead. Given some known voltage at the input to the resistor, the resistor-capacitor combination works according to the V is proportional to 1-exp(-t/rc) rule where t is time and rc are the corresponding values of the resistor and the capacitor. Or something like that. All-in-all, the neural net neuron is a fairly neat dual of the nervous net neuron. Same hardware, just arranged differently.

The places I go when I am looking for parts are: Active Electronics and Intek both are at Boundry & 1st on the Vancouver-Burnaby boarder. Also check out RPE electronics at 4th & Arbutus (Van. West-side). They occasionally have cool junk in the back and they do have FLED's. The parts for my solar rollers came from there. As for mail order, try Digi-Key, they have just about everything you need. For solar cells...Solarbotics is still the best source in Canada. Check out the junk stores...tell all your freinds to give you their electro-junk (I still have 3 Cd player, 4 video decks, 2 cassette decks and a cash register among a pile of other junk that needs to be taken apart(see rule Seven of the Laws of BEAM Robotics)). Stock-pile the junk, and you'll always have parts. :) ps. I do believe that mail order is possible from the stores in Vancouver...not 100% though...ok...so check it out.

My name is Bob Brady and I am a new BEAMer. So new, that only yesterday I breadboarded my first solarengine circuit. I got the circuit diagram from Mr. Dave Hrynkiw when I ordered the Solarengine kit from his solarbotics.com company. My interest in BEAM came from what I interpret to be its hallmark: Derive the complex from the simple. And I'm talkin' strikingly complex from the elegantly simple. For example, take Sir Issac's Force = Mass * Acceleration. Simple, compact, elegant. And yet, Ka-pow! A lot of complex stuff derives from it. Same reaction when I first found out about BEAM. The solarengine is really an elegantly simple device. For any young person out there who is thinking maybe this is high falutin' techno material, I say to heck with it, you can just go out to Radio Shack or wherever and buy the parts and cookbook it, paint-by-the-numbers, connect the dots put together the pieces and it'll work. You can worry about the hows and whys sooner or later whenever you like. It took me a couple of tries. I must of had some trouble pushing the transistor leads into the breadboard (jargon) because it took me a few tries to get it right. I'm a mechanical engineer with a Ph.D. and I'm a certified bell-ringin' monk (not a priest, they do have standards) at one of America's cathedrals of science. My formal educational background is in mechanics (B.S.), alternative energy (M.S.), and machine vision (Ph.D.), all of which, BEAM lends itself to quite readily. I like the elegance of BEAM. It's a hobby that's easy on the pocketbook. And some of the pioneers in the field are still willing to give common Joes like me tips. What a deal! Well dear reader, Howdy-Do!

They are expensive, heavy, difficult to balance, drift, and consume more power than they are worth. Here's a better idea. put an optical interupter at the end of a coil meter movement and bias with amplifiers so the needle stays inthe middle of the interrupter. Take a parasitic feed from the amplifier feedback and you will have a perfect first-difference balance indicator. And more if you put black wire insulation over the needle so that the inertial effects are improved. $0.02. markt. $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256492.000ED7AA; Thu, 8 May 1997 19:42:07 -0700 Received: from gromit.webconn.com (root@gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id TAA19750 for ; Thu, 8 May 1997 19:32:06 -0700 Received: from huey.cadvision.com (huey2.cadvision.com [207.228.64.2]) by gromit.webconn.com (8.8.5/8.8.5) with ESMTP id UAA06808 for ; Thu, 8 May 1997 20:36:58 -0500 Received: from ts49ip236.cadvision.com (ts49ip236.cadvision.com [207.228.72.236]) by huey.cadvision.com (8.7.5/8.7.5/DCX/TRI) with SMTP id TAA192938 for ; Thu, 8 May 1997 19:33:11 -0600 Received: by ts49ip236.cadvision.com with Microsoft Mail id <01BC5BE6.6BE05180@ts49ip236.cadvision.com>; Thu, 8 May 1997 19:31:27 -0600 Message-ID: <01BC5BE6.6BE05180@ts49ip236.cadvision.com> From: Hyndman To: "beam@webconn.com" Subject: RE: chicken leg walkers Date: Thu, 8 May 1997 19:31:14 -0600 MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable SMTPOriginator: hyndmanm@cadvision.com From: hyndmanm@cadvision.com Subject: RE: chicken leg walkers PostedDate: 05/08/97 06:31:14 PM SendTo: beam@webconn.com $UpdatedBy: CN=Athena/O=DLNOTES/C=US,CN=Laurence Mayer/O=DLNOTES/C=US RouteServers: CN=Athena/O=DLNOTES/C=US RouteTimes: 05/08/97 07:42:17 PM-05/08/97 07:42:19 PM DeliveredDate: 05/08/97 07:42:19 PM Categories: $Revisions: BlindCopyTo: CN=Laurence Mayer/O=DLNOTES/C=US I don't really know much about the chicken leg walkers, but you might want to try springs, that usually my answer to most balance problems.

Nowhere but in Mark's multi-drawered cranium! Actually, we're trying to persuade him to release parts of it as magazine articles, but that'll take massive bribes involving quantities of Rice Pudding and Coffee Crisp bars...

Sounds like you're running into the manufacturing tolerances problem, where the resistors are +/- 5% and the caps are +50%/-20% (I think that's what it is). Only way to tune it is by swapping out caps/resistors (or measuring them before you put them in) until they're about right. But honestly - in almost all walkers, a little left/right bias doesn't adversely affect the walking gait. It's a minor problem at best. -Dave -- "Um, no - that's H,R,Y,N,K,I,W.

I have found nice, small gears at a specialty store for racing slot cars. They have a track, kits, parts, and etc. If you don't have one of these specialty places nearby, a hobby shop for radio control models might also have replacement parts for slot cars. . . These places are handy, but I do think that they are expensive. But, what do I expect?

If I read them correctly, the LM386 spec say it will work from > 4 - 12 volts. Will it be underpowered? Non-functioning? I used 9 volts because I had previously gotten some surplus low-current 9 volt gearhead motors, and 9 volt batteries are nice and small. I'm not sure if the 386 output can swing rail-to-rail, so it might be a bit lopsided at lower voltages (but you can probably compensate with the trimmer). However, it's may be (probably is) the case that the LM386 can't handle enough current for typical cheap toy motors (has anyone had experience they could share on this?) I'd try it with the amazingly cool, amazingly tiny gearhead motors that Jim Eaton described a week or so back from Marlin P Jones. They are tiny, $7 each. They're pretty slow to start with (not bad for this kind of robot), but if you're into speed, I have successfully modified the geartrain to speed them up quite a bit (if anyone is interested I'll post directions and pictures. basically, you take the next to the last gear out of the geartrain, and crimp the next to the next to the last gear onto the shaft it normally spins around, which happens to be connected already to the last gear. sorry if i'm being confusing :-) ).

Agreed, they are great motor/gearboxes. I ordered plenty (fear of never-see-again). I was surprised at the torque I got out of 3.3v/55mA (sorry, no mechanical measure). They mesh oh-so-nicely...making a sound that all good 'bots should have. > but if you're into speed, I have successfully modified the geartrain to > speed them up quite a bit While the motor as-is provides a great 32rpm for legged beings (except for 0 compliance), that fix should do nicely for small/speedy wheeled jobs. (Any RPM measures Randy?) My quick eyeball estimate is about 8 x original ~= 256(my lucky number)rpm. Seems kinda fast, but I'm using oversize wheels. I took one up to 6v for short periods. I could audibly detect a curve where more voltage yielded little-more rpm. Seemed optimal around 3.6-4v, but I have no long-term guarantee at that voltage. Does anyone have endurance specs on these motors? Otherwise, I'm going to test some limits on one. !!Dean (i love! parenthesis) Hall $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256494.00252159; Sat, 10 May 1997 23:45:33 -0700 Received: from gromit.webconn.com (root@gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id XAA00415 for ; Sat, 10 May 1997 23:35:12 -0700 From: DBFoster99@aol.com Received: from emout06.mail.aol.com (emout06.mx.aol.com [198.81.11.97]) by gromit.webconn.com (8.8.5/8.8.5) with ESMTP id BAA25394 for ; Sun, 11 May 1997 01:09:23 -0500 Received: (from root@localhost) by emout06.mail.aol.com (8.7.6/8.7.3/AOL-2.0.0) id CAA27555; Sun, 11 May 1997 02:09:15 -0400 (EDT) Date: Sun, 11 May 1997 02:09:15 -0400 (EDT) Message-ID: <970511020915_-1231666436@emout06.mail.aol.com> To: bkopena@erols.com, beam@webconn.com Subject: Re: Gears SMTPOriginator: DBFoster99@aol.com From: DBFoster99@aol.com Subject: Re: Gears PostedDate: 05/10/97 11:09:15 PM SendTo: bkopena@erols.com,beam@webconn.com $UpdatedBy: CN=Athena/O=DLNOTES/C=US,CN=Laurence Mayer/O=DLNOTES/C=US RouteServers: CN=Athena/O=DLNOTES/C=US RouteTimes: 05/10/97 11:45:37 PM-05/10/97 11:45:38 PM DeliveredDate: 05/10/97 11:45:38 PM Categories: $Revisions: BlindCopyTo: CN=Laurence Mayer/O=DLNOTES/C=US >This is probably in a FAQ somewhere, but anyway: > >I've been thinking about building a Herbie robot as my first robot.

In the June '97 copy of Electronics Now they have plans for a solar-roler type beam-bot. It uses a nice simple (not very efficient) friction drive system. Basicly you slip a piece of wire insulation or the rubber cover off a toggle switch over ther end of the motor shaft, then place the motor so it rests on the outside of the much larger diameter rubber drive wheel. This solves both the drive coupling & gear reduction problems. It's worth a try anyway. good luck, Dave Foster $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256494.00254F05; Sat, 10 May 1997 23:47:30 -0700 Received: from gromit.webconn.com (root@gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id XAA00418 for ; Sat, 10 May 1997 23:37:32 -0700 Received: from huey.cadvision.com (huey2.cadvision.com [207.228.64.2]) by gromit.webconn.com (8.8.5/8.8.5) with ESMTP id AAA25256 for ; Sun, 11 May 1997 00:59:07 -0500 Received: from ts68ip163.cadvision.com (ts74ip50.cadvision.com [207.228.113.50]) by huey.cadvision.com (8.7.5/8.7.5/DCX/TRI) with SMTP id XAA131430 for ; Sat, 10 May 1997 23:55:43 -0600 Received: by ts68ip163.cadvision.com with Microsoft Mail id <01BC5D9D.8F08D2A0@ts68ip163.cadvision.com>; Sat, 10 May 1997 23:54:55 -0600 Message-ID: <01BC5D9D.8F08D2A0@ts68ip163.cadvision.com> From: Hyndman To: "beam@webconn.com" Subject: RE: voltage for a "herbie" Date: Sat, 10 May 1997 23:54:45 -0600 MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable SMTPOriginator: hyndmanm@cadvision.com From: hyndmanm@cadvision.com Subject: RE: voltage for a "herbie" PostedDate: 05/10/97 10:54:45 PM SendTo: beam@webconn.com $UpdatedBy: CN=Athena/O=DLNOTES/C=US,CN=Laurence Mayer/O=DLNOTES/C=US RouteServers: CN=Athena/O=DLNOTES/C=US RouteTimes: 05/10/97 11:47:40 PM-05/10/97 11:47:40 PM DeliveredDate: 05/10/97 11:47:40 PM Categories: $Revisions: BlindCopyTo: CN=Laurence Mayer/O=DLNOTES/C=US -----Original Message----- From: Randy Sargent [SMTP:rsargent@newtonlabs.com] Sent: May 10, 1997 8:53 PM To: Bruce Kopena Cc: beam@webconn.com Subject: voltage for a "herbie" > The cars they come with run at 3 - 6 volts (AA batteries).

I used 9 volts because I had previously gotten some surplus low-current 9 volt gearhead motors, and 9 volt batteries are nice and small. I'm not sure if the 386 output can swing rail-to-rail, so it might be a bit lopsided at lower voltages (but you can probably compensate with the trimmer). However, it's may be (probably is) the case that the LM386 can't handle enough current for typical cheap toy motors (has anyone had experience they could share on this?) I'd try it with the amazingly cool, amazingly tiny gearhead motors that Jim Eaton described a week or so back from Marlin P Jones. They are tiny, $7 each. They're pretty slow to start with (not bad for this kind of robot), but if you're into speed, I have successfully modified the geartrain to speed them up quite a bit (if anyone is interested I'll post directions and pictures. basically, you take the next to the last gear out of the geartrain, and crimp the next to the next to the last gear onto the shaft it normally spins around, which happens to be connected already to the last gear. sorry if i'm being confusing :-) ). To find the motor, see http://www.mpja.com and go to the "new products" page. I think that Jim Horner got his bot to work with 4 nicads, for around 4.8v (check out his message from May 9). Jim, what kind of motors did you end up using? There is some nice pager motor's that you can get from a person not very far from this mail list. Dave "smith" sells brand new 1.4 volt pager motors, they are small but they have great power for their size. Dave shrinks heat shrink tubing on the shaft for better traction, which is nice on his part. The cost is $10 Canadian, which is around $7.30 US, $6 shipping ground anywhere, but if you talk to him he might be able to arrange for you to pay for postage. Looking at the snail mail system, I would pay the $6 if you want to be assured that you will get the motor. Hope I helped a little D.

And as some don't have a Digest facility ,this precludes the Email Client from sorting the In Box effectively. Th is expedites organizing the Email without having to read 30 pieces of email per day in order to sort them. Then, at your leisure, you can read one selection of email lists. A simple suggstion to add a prefix "BEAM@" (or another) to the subject field will solve this problem.

The friction drive and several other items in the article were learned by the author, John Iovine, with the help of members of this mailing list. You'll notice that in the section he titled "Building a BEAM Robot" he claims that his circuit is ". . .an improved variation of a circuit originally designed by Dave Hrynkiw of Canada." You'll probably recognize Dave a a frequent contributor to tihs list. He is certainly an excellent source for the speciallized components we sometimes crave.

In both I used those little 3V open frame motors that Goldmine has had in their catalog for the last couple of years for $0.89.

I will take this to the provider and ask.. If you have questions about this do not put it on the list, send it to: beam-request@webconn.com Actually I get about 200 e-mails/day. Thanks!

I was down at my work bench with my kids this afternoon, and one of them found a little wind up hopping birthday cake. We played with it for about 10 minutes until they got bored, then I played with it some more. It really worked well, very active. I've seen these things before, but this was the first time while having the echos of a beam discussion going on in my head. I haven't done anything to investigate its guts, but I suppose it works by creating a resonate bouncing mass and the clock work just pushes it hard enough each cycle to overcome the loss in the system. That coupled with feet big enough to keep it from falling over and you've got one energetic little critter. This resonate bouncing mechanism seems quite different from what was described here lately. Has anyone done anything along these lines? You guys who have been doing this forever, what do you think of the idea?

I do remember seeing these things before, but it has been ages since I've looked at one 'up close'. Some of us have built hoppers (Mark T. and Miller) and we've discussed doing a 'resonant hopper' but I haven't seen one yet. . . I wonder if you could carve away enough plasti- junk to allow the mass of a pager-motor type solar engine? Then you would not have to compensate for a change in mass in the resonant system. There are others here that have _far more_ knowledge of resonance than I do, so let hear from them. . . . If we're lucky we might even hear from the "Mighty 'D'", on resonance (shh Richard). . . Let us know what you find out, John. I'll be especially interested in how you connect to the wind-up mechanism. I do have a glimmer of a beginning of the start of an idea, but you'll have yours done by then. Cheers, Richard. $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256495.000D4677; Sun, 11 May 1997 19:25:00 -0700 Received: from gromit.webconn.com (root@gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id TAA00908 for ; Sun, 11 May 1997 19:15:00 -0700 Received: from mailgate.execpc.com (mailgate.execpc.com [169.207.16.5]) by gromit.webconn.com (8.8.5/8.8.5) with ESMTP id UAA32241 for ; Sun, 11 May 1997 20:23:36 -0500 Received: from mail.execpc.com (mail [169.207.16.2]) by mailgate.execpc.com (8.8.5/8.8.3) with ESMTP id UAA11225 for ; Sun, 11 May 1997 20:23:28 -0500 Received: from LOCALNAME (princess-leia-organa.mdm.mke.execpc.com [169.207.72.98]) by mail.execpc.com (8.8.5/8.8.3) with SMTP id UAA02326 for ; Sun, 11 May 1997 20:23:26 -0500 (CDT) Message-ID: <33767B77.3EC9@execpc.com> Date: Sun, 11 May 1997 19:07:51 -0700 From: "Michael A.

It uses a 74HC14 IC and 0.22 uF silver mica capacitors. The module worked right away. I plan to make a microcore breadboard for testing different output circuits. After that project is finished, I hope to build a walker. I'm especially interested in Walker Sumo and High Jump/Long Jump competitions. Have people used the microcore in these types of robots?

A while back I mentioned my research in creating a robotic "food chain".

Once the eco-system is balanced, they all work pretty well! The web page is only hours old so it's got a few rough edges... but I'm eager to share it with you... www.nucleus.com/~cybug I like to call this arm of BEAM research, "high energy-BEAM" since it allows creation of robots without off switches which operate at higher energy levels, allowing more sophisticated behaviour without energy cielings.

I got a few replies (which I promised I would summerize).. At least 4 new people have built Walkers using the WWW information (Great job Miller!!). And at least one other is on the way, the microcore is built.. Some people have a few suggestions and others a few questions.. Others may have suggestions/ideas for these people to help get them going with: motor sources - I just got my 10 motors from Marlin P.

My list of resources is: http://lenti.med.umn.edu/~mwd/robot/resource.html I hope this summary will both let people know they have significantly helped others build, and also help others know they can also. Thanks! Mark John (of John & Kelly): jaandkh@concentric.net wrote: I've buit three walkers. The first was an attempt at a four motor walker which failed rather spectacularly, and destroyed one of my motors. Out of the ashes I've built a two motor walker using Miller's pages. I worked very well until I reworked the electronics to make them more pleasing to the eye. Now it doesn't work any more :-( From my last motor I'm building a single motor walker. I don't have pictures, or a web page yet, but they're both in the works. I've also built several solarollers. I have pictures of them, and they will also show up on my web when I have time to accomplish it. Plans for the future include two three motor walkers, and as soon as I find the motors, a BIG walker of at least 3 motors. Bob Bankston: kiowawarrior@ibm.net I was able to breadboard the basic microcore circuit from A. Miller's BEAM site and then breadboarded M. Tilden's schematic in "The Patent". I was able to get both functioning after only some minor tweeking. That's about as far as I got so far due to work commitments (that and I need to learn how to etch PC boards). Hopefully, I'll be able to get back to it in August after I move to Germany (US Army). Roger Mertin: roger_mertin@dynapro.com RogerJames_Mertin@bc.sympatico.ca I just completed a BEAM walker ( based on miller's website info.) Works pretty good,now to add the neural nets for upper lever processing. Patrick De Groote: PDG@unisource.be I did start building a microcore (as per instructions on Millers page) and it _does_ work. I then reworked 2 old model-airplane servo's and hooked these up. The legs were made out of wire from wire coat-hangers... (its solid, and cheap...) and the actual chassis from some scrap aluminum. The microcore itself is still on breadboard. Now I only need time to get to a decent printed ciruit board. by the way: the walker walks (although it still needs some timing adjustments before it will walk somewhat straight...) ====================== Close to being a Walker... ETetirick@postoffice.worldnet.att.net I've interfaced the motors with the 74als245's and they are running and oscillating but the problem is that the motors oscillate more one way than the other. Does anyone have any suggestion as to how to make the oscillations even so that the motor shaft will not rotate?

I will look into ways to alter the capacitor charge/discharge cycles. Do you have all of the microcore material from the AMILLER web site? For a simple circuit, it sure is slick. We're probably going to see a few million dollar robots with microcores doing all the real work.

I finally got to read the Living Machines Paper. It was very interesting but I have a few questions. What is an adaptive linkage and how is one made? Also what do all the symbols in the neural diagrams mean? (nu/nv- vs. nu/nv+). How is sensory input achieved? Specifically how is phototropism accomplished. Would it be possible to get schematics on more comples neural networks like lobster or Walkman? Thanks for all your help. I also have some ideas. Why not create a chip with a relatively large Nu network? Such a chip would have fast neurons with adaptive linkages. The outputs could be reguler Nv neurons. In addition it would have inputs. The most important thing that could be added would be Pl("pleasure") and Pn("pain") pins. The Pl pin would encourage the linkages to stay the same. The Pn pin would encourage them to change. Also linkages would be less likely to "break" the longer that they are active. This would prevent a learned creature from suddenly "forgetting" everything if it is subjected to "pain". The pl could be attached to a forward motion sensor, and thus encourage the machine to move in a forward direction. Pl/pn connections could also be added to photo sensors to encourage the development of intelligent phototropic behavior. On another subject, does anyone know where I could get VERY cheap motor/gearboxes/geared-motors? Especially in Phoenix? Also, are there any other beamers in Phoenix? If so, maybe we could have a meeting or something or make a newsletter? Thanks for your help.

My work has been aimed at the inner workings of a microcore--with my interests being on the entire nervous system. I have yet to build a walker, although i do have motors, the microcore all working together--just not the mechanics (can't figure out a nice *elegant* way to attach the motors to the legs). I have *many* nervous nets running of various uses (uselessness?) --investigating memory and sensory input. i have been looking at non-conventional BEAM machines--like dangling structures (kinda similar to the _Flock_ by Ken Rinaldo) and many-legged crawling structures (yes, Ken Chen, like a centi-pede :). My nervous nets are based on yet again, Miller's site which gave me a great start along with Tilden's patent. >> I have been trying find out a method in which a sensor (such as a >> photodiode) can instigate a process into a microcore.

Forwarded to the group from markt's mailbox. Mark, I am a novice in the BEAM robot area (we just got the type-1 Solarengine) and my high school son has to help me figure it out. However, I'm really enthusiastic about where the BEAM philosophy is going. I live in Northern Va and I wasn't able to make it to the workshop in Los Alamos last month. My son and his friends also really wanted to attend but it just didn't fit the budget and the schedule. Are there going to be any workshops on the east coast (particularly in the Va/Wash. DC/Md area)? If not, do you think there would be any interest in organizing one? I'm currently a Navy guy working in the Naval Aviation Science and Technology Office and we coordinate programs with the Office of Naval Research and other government agencies. I would be glad to help organize a workshop in our area if there is interest. There are quite a few government labs and organizations in the area that we could get to sponsor us (NRL, ONR, ARL, DARPA, etc) if we thought there was significant interest.

Thanks for the additional pointers. I'm looking forward to having an electronic beetle running around the house. I remember seeing a video tape that showed how points on the human body move sinusoidally. The microcore's charge/discharge cycles seem to model this process. Although I'm still testing, I think that failed processes destroy the charge/discharge symetry in the system. Time for bench work... More Questions: As pulse trains are injected into the system, do they change the loop frequency (viewed across all nodes)? If you add enough pulse trains, does the waveform plotted by using the analog values on each capacitor change? You may need a large chain to test this. The human body has points where various nerves come together. Do microcore robots combine loops the same way? >From memory: Dr. Robert Becker found a hidden DC control loop within the nervous system. Does the microcore implement this when it senses motor current, or is another type of module required? Maybe, we can control the bias to the 1M resistors instead of grounding them. Cheers, Michael A.

In the circuit below, should the LED turn on (at the same intensity) when no voltage is supplied to vIn or vRef as well as when 9 volts is supplied to vIn?

Two things: I think that you are only looking at part of the circuit that 'Herbie' uses. There is a second motor (or in your case LED) from Vcc to the amp output. The audio amp (LM386) has a fair 'linear region' that the comparator does not. In other words: The comparator that you (may be) testing with is has an output that is designed to go from 'output-hi' to 'output-low' and back again with no 'in-between'. An audio amp (ideally) is nothing but 'in-between' in varying shades, with no 'all-or-nothing'. Given two motors / LED's the output in the middle determines the voltage across the two LED's. So a 'middle' amp output gives two equally (but not fully) lit LED's. A 'higher' amp output lights the lower LED brighter (and the upper, not so bright).

(While having the linear region can result in a more fluid motion, an amp with a high gain can still make a decent line/light follower/avoider. Upping the gain to 200 by hooking up pins 1 and 8 on the LM386 makes it much more comparator-link, and seemed to help me for line following in particular.) I'm not sure if the 741 will be able to give enough current to run motors very well. If you do try it out, I'd be curious to hear how it works. -- Randy ---------------------------------------------------------------- Randy Sargent Newton Research Labs Senior Design Engineer Robotic Systems and Software rsargent@newtonlabs.com http://www.newtonlabs.com/ $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256497.0024F992; Tue, 13 May 1997 23:43:51 -0700 Received: from gromit.webconn.com (root@gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id XAA08579 for ; Tue, 13 May 1997 23:33:37 -0700 Received: from alpha.LOGAN.NET (mail.logan.net [207.51.128.10]) by gromit.webconn.com (8.8.5/8.8.5) with ESMTP id BAA19099 for ; Wed, 14 May 1997 01:04:56 -0500 Received: from default ([207.51.128.251]) by alpha.LOGAN.NET (post.office MTA v2.0 0813 ID# 999-32390) with SMTP id AAA52 for ; Wed, 14 May 1997 02:01:37 -0400 Message-ID: <337953ED.4049@logan.net> Date: Wed, 14 May 1997 01:55:57 -0400 From: stalker@logan.net (David Miller) Organization: Digital Blitz X-Mailer: Mozilla 3.01Gold (Win95; I) MIME-Version: 1.0 To: beam@webconn.com Subject: Popular Science Article Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit SMTPOriginator: stalker@logan.net From: stalker@logan.net Subject: Popular Science Article PostedDate: 05/13/97 10:55:57 PM SendTo: beam@webconn.com $UpdatedBy: CN=Athena/O=DLNOTES/C=US,CN=Laurence Mayer/O=DLNOTES/C=US RouteServers: CN=Athena/O=DLNOTES/C=US RouteTimes: 05/13/97 11:43:55 PM-05/13/97 11:43:55 PM DeliveredDate: 05/13/97 11:43:55 PM Categories: $Revisions: BlindCopyTo: CN=Laurence Mayer/O=DLNOTES/C=US There was a article in this months Popular Science that caught my eye. It says that some researchers from the U. of Tokyo have been working on a "robo-cockroach". But as I read further it turns out that they are taking real cockroaches and adding a small backpack with a remote receiver, batterys, etc. They then stimulate the cockroach through various electrodes to steer it through simple mazes.(Cockroach/Terminator) They are theorizing that the roaches can be made to carry mini cameras and preform inspection trips into tiny spaces. They go on to say that mechanical devices can not match the size, speed, and agility of the average roach. It seems they have seen my old dorm when the lights were fliped on. The gist of this got interesting in the final paragraph when the reporter says that the research in aimed at finding out more about how the insect neural system works. What a cool idea I can hook up my teaching assistant and send him for pizza with one of these gadgets. I am more interested in how they got the reciever circuit small enough to fit on the roach! I feel an idea coming on. My undergrad project used a small robot to map rooms using its own random movements, and positions of where it ran into things. With this type of feedback system you could slave some BEAM robots to a central processor and let them search for things in spaces that were too small to enter. The robot would be autonimous and take signals from the computer when it got some input from them that triggered its programming. I have a few ideas for the control circuitry. I will know a little more after I sit down with Electronic Work Bench tonight. For those interested in the original article take a look at page 44 of the June 97 Popular Science, Very Cool! $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256497.002B2D46; Wed, 14 May 1997 00:51:36 -0700 Received: from gromit.webconn.com (root@gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id AAA08662 for ; Wed, 14 May 1997 00:41:27 -0700 Received: from huey.cadvision.com (huey.cadvision.com [204.50.1.2]) by gromit.webconn.com (8.8.5/8.8.5) with ESMTP id BAA19391 for ; Wed, 14 May 1997 01:48:11 -0500 Received: from Solarbotics (ts40ip171.cadvision.com [207.228.71.171]) by huey.cadvision.com (8.7.5/8.7.5/DCX/TRI) with SMTP id AAA108140; Wed, 14 May 1997 00:44:30 -0600 Message-Id: <3.0.1.32.19970514004810.00ec7f9c@cadvision.com> X-Sender: skip@cadvision.com X-Mailer: Windows Eudora Light Version 3.0.1 (32) Date: Wed, 14 May 1997 00:48:10 -0600 To: Scarius , beam@webconn.com From: Dave Hrynkiw Subject: Re: Op-Amp & Herbie In-Reply-To: <337928C7.2E0@erols.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" SMTPOriginator: dave@solarbotics.com From: dave@solarbotics.com Subject: Re: Op-Amp & Herbie PostedDate: 05/13/97 11:48:10 PM SendTo: bkopena@erols.com,beam@webconn.com $UpdatedBy: CN=Athena/O=DLNOTES/C=US,CN=Laurence Mayer/O=DLNOTES/C=US RouteServers: CN=Athena/O=DLNOTES/C=US RouteTimes: 05/14/97 12:51:46 AM-05/14/97 12:51:47 AM DeliveredDate: 05/14/97 12:51:47 AM Categories: $Revisions: BlindCopyTo: CN=Laurence Mayer/O=DLNOTES/C=US At 10:51 PM 5/13/97 -0400, Scarius wrote: >Please tell me if these kind of questions don't belong here, and >you'd like me to stop posting them.

Thanks for the compliment :) However, my photovore is not microcore-based, and the circuitry used will not "instigate a process into a microcore". Also I'm not sure that is the way to go; you may want to merely alter the timing of an existing process. I can imagine various ways of achieving this. For instance, since the 1M resistors in the basic microcore connect to ground, you could exchange one for two resistors in series, and short out the bottom one using a transistor or 3-state output. Two photodiode `eyes' and/or feelers connected to a schmitt-trigger might then select one of two time constants.

With one small problem, after several minutes, the roach realizes somehow that it is being controlled and ignores the signals forever. This same problem has been shown with almost any animal that the military has tried to control (Even the most well trained dogs will not listen to their masters through walky-talkies. Strange but true) the only solution is to somehow scoop out the central nervous system in a roach and replace it with a potenially beam like controller. Madagascar hissing roaches are large enough for the task, but this is pretty disgusting work, so I'm sticking to machines for the time being. And for your info, Prof. Shimoyama's students use a pic processor with double AtoD outputs for control, stimulated from an IR transmitter hooked to a computer.

The LM386 is an audio power amp that has its output biased to 1/2 Vcc when the inputs are equal, and has a minimum output of 250mA. I think the 741 can only source/sink about (WAG) 20mA, so you would probably need to add output transistors to drive motors. You can get the LM386 data sheet from nat-semi's web site (www.national.com I think).. tho national doesn't show a line follower in its apps :). As Richard illustrated with his graphs, using the op-amp as a comparator will give either/or operation at the output, so you might want to put a 100K or so trimpot between the output and the -input, feed the signal (junction of your photo-resistors), to the same input, and use the +input as Vref (basic inverting amplifier).

I am thinking of hosting a three or four day workshop at an east coast resort. It would be a way for a few of you to get to know each other, and me, better through eight or so hours a day of building, demonstrations, building, examples, building, lectures, building, and maybe a little building. I'm imagining a sort of BEAM-Triathlon: Robots, Golf, Seafood! If I were looking to attend something like this I would be looking for: individual instruction / attention; a relaxed, productive environment; a full schedule of interesting activities and/or diversions. If you have a different perspective on this, speak-up!

I keep trying, but I don't want to damage it, the temperature is higher so that the solder will melt faster, nothing seams to work. Thanks More temperature is exactly what you DON'T need. The cell pads are easily burned off. You may be able to salvage it by carefully cleaning the pads off with alcohol and then GENTLY scraping the surface with sandpaper so you can see the particles of copper again. You should then be able to solder to it. If you see thru the pad - you've gone too far (toast). You may try using "automobile defogger repair paint" to recover the pads, then solder to them - I've heard it works well (but a little expensive).

There are the Tamiya kits that usually run about $15 but are rather bulky. The other option at the same place is to modify a "standard" R/C servo - $10 to $50 -. That is what me and most of my friends have been doing. There are places like MicroMo (813-572-0131) that specialize in precision gearhead motors, but they're not cheap. I managed to get a couple of "dead" servos from one hobby shop for $1.00 each. In each one the same tantalum cap was blown. Remove the servo board and the pot tab -tadaa- one DC gearhead motor. In the solar front, Motorola has a new dual transistor MBT3904DW1T1 (replace 3904 with 3906 or 3946) in a 0603 size body (approx. 2mm by 1mm) - 6 pins with 2 of 3904's, 3906's or one of each. Max Ic is 200 mA so it wouldn't be that great for driving the motors, but ok in the triac cct. Look for these in a solaroller near you!

The ones that have solder blobs on them already are the easiest though. For the ones that just 'wont' take solder, you can try a couple of things: 1) Make a mechanical connector: a piece of brass tubing with a slot cut in it can be slid on to the cell, and will do a fair job. I do this with the slot just a bit thinner than the cell, then pry it open and slide it on. When it pinches shut on the remains of the solder pad, it will pick up the current and stay in place. (well, sort-of) 2) Use conductive glue: Automotive stores have a paint that is used to repair rear window defogger strips. It is conductive when it dries, but not very strong mechanically. A drop of instant glue over the defogger paint will help. Cheers, and good luck, Richard. $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256498.0012B6B3; Wed, 14 May 1997 20:24:23 -0700 Received: from gromit.webconn.com (root@gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id UAA11962 for ; Wed, 14 May 1997 20:14:21 -0700 Received: from huey.cadvision.com (huey.cadvision.com [204.50.1.2]) by gromit.webconn.com (8.8.5/8.8.5) with ESMTP id VAA27510 for ; Wed, 14 May 1997 21:45:27 -0500 Received: from ts68ip163.cadvision.com (ts70ip250.cadvision.com [207.228.75.250]) by huey.cadvision.com (8.8.5/8.8.5/DCX/TRI) with SMTP id UAA51116 for ; Wed, 14 May 1997 20:41:57 -0600 Received: by ts68ip163.cadvision.com with Microsoft Mail id <01BC60A7.613E2980@ts68ip163.cadvision.com>; Wed, 14 May 1997 20:42:46 -0600 Message-ID: <01BC60A7.613E2980@ts68ip163.cadvision.com> From: Hyndman To: "'beam@webconn.com'" Subject: RE: BEAM: Re: Soldering to solar cells Date: Wed, 14 May 1997 20:42:40 -0600 MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable SMTPOriginator: hyndmanm@cadvision.com From: hyndmanm@cadvision.com Subject: RE: BEAM: Re: Soldering to solar cells PostedDate: 05/14/97 07:42:40 PM SendTo: beam@webconn.com $UpdatedBy: CN=Athena/O=DLNOTES/C=US,CN=Laurence Mayer/O=DLNOTES/C=US RouteServers: CN=Athena/O=DLNOTES/C=US RouteTimes: 05/14/97 08:24:34 PM-05/14/97 08:24:34 PM DeliveredDate: 05/14/97 08:24:34 PM Categories: $Revisions: BlindCopyTo: CN=Laurence Mayer/O=DLNOTES/C=US Thanks for all of your help, I decided to pick up some epoxy tomorrow then use it on my other solar cell, and try the soldering/ adding metals on the one I was having trouble with.

I believe it is copper sintered into the material for solderability. Which brings me to my next point: Solarbotics will soon be carrying solarcells with the pads PRE-TINNED. So the risk of "toasting" the solarcells will be far less. For those of you who have ordered cells from Digi-key, you'll know what these look like. Nice little blobs of solder, ready to remelt pronto - not these tricky-to-solder-to units we presently have. Don't expect them for at least another few months or so... -Dave -- "Um, no - that's H,R,Y,N,K,I,W. No, not K,I,U,U, K,I,_W_. Yes, that's right. Yes, I know it looks like "HOCKYRINK."

IMHO, to make the long costly trip worthwhile, I'd like to see it jam-packed with seminars, demonstrations, exhibits, and competitions, all going on several at a time. Also need distractions for those of us who would bring family, or just get to relax with new-found friends. Perhaps this sounds like a lot, it's a regular professional conference that demands a lot of work. But anyway, that's my thought for this group's consideration. --Mike ~~~~~~~~~~ KrisTech Robot Magazine ~~~~~~~~~~~ (updated weekly) HUMANITY CAN MAKE REALLY INTELLIGENT ROBOTS.

Have I opened a "can of worms"? I will try to clarify my thoughts, a bit. I am considering 'hosting' an event or events depending on interest. The event would consist of several components, both 'formal' and informal. The formal components would include: BEAM training: Talking, lecturing, ranting and demonstrating to the best of my ability. Question and answer galore! BEAM building: All of us soldering, cutting and drilling-up a storm. Steal ideas from the student beside you! Technology Feeding Frenzy: I'll supply cool stuff that you can use to build your demo units with, or you can hoarde them for your next project. This is the format of the meetings that we have when we BEAM'ers meet for our (not frequent enough) face-to-face sessions. I am open to adding more formal components. For example, novice events would include the following: Hand Tool Primer: Workshop safety, tool selection and use, all fasteners great and small. Learn to solder: This would be a required element of any novice-level event. The informal components would vary according to event site, and student interest. The possibilities are endless, but to list a few: Hot Springs: This has become a bit of a habit with some of us. Nobody has actually proclaimed that we won't go to a place that can't provide us with a good 'sulfur-soak', but. . . Golf: "A nice walk ruined by a little ball." Beach time: I enjoy morning and evening walks on the beach. Good time for reflection on that latest sensor design. Seedy nightclubs: See a punk band; drink Canadian booze; have your brains squirt out your ears when they turn-up the amplifiers; land in a heap when the bouncer escorts you out. Skiing: "Some sport! Slide down a hill on waxed boards. Ha! Try _not_ sliding, that's a sport!" Culture: The symphony, theatre, ethnic food . . . Et cetera. Clearly these are a matter of inclination and location. My Toronto home is an ideal base for the last three items, the resort property on a mid- Atlantic beach is better for some others. As an aside, there is a beach in Toronto, we are on Lake Ontario, after all. Somehow it loses something in the translation though. Let's propose this for a four-day event.

Have I opened a "can of worms"? I will try to clarify my thoughts, a bit. I am considering 'hosting' an event or events depending on interest. The event would consist of several components, both 'formal' and informal. The formal components would include: BEAM training: Talking, lecturing, ranting and demonstrating to the best of my ability. Question and answer galore! BEAM building: All of us soldering, cutting and drilling-up a storm. Steal ideas from the student beside you! Technology Feeding Frenzy: I'll supply cool stuff that you can use to build your demo units with, or you can hoarde them for your next project. This is the format of the meetings that we have when we BEAM'ers meet for our (not frequent enough) face-to-face sessions. I am open to adding more formal components. For example, novice events would include the following: Hand Tool Primer: Workshop safety, tool selection and use, all fasteners great and small. Learn to solder: This would be a required element of any novice-level event. The informal components would vary according to event site, and student interest. The possibilities are endless, but to list a few: Hot Springs: This has become a bit of a habit with some of us. Nobody has actually proclaimed that we won't go to a place that can't provide us with a good 'sulfur-soak', but. . . Golf: "A nice walk ruined by a little ball." Beach time: I enjoy morning and evening walks on the beach. Good time for reflection on that latest sensor design. Seedy nightclubs: See a punk band; drink Canadian booze; have your brains squirt out your ears when they turn-up the amplifiers; land in a heap when the bouncer escorts you out. Skiing: "Some sport! Slide down a hill on waxed boards. Ha! Try _not_ sliding, that's a sport!" Culture: The symphony, theatre, ethnic food . . . Et cetera. Clearly these are a matter of inclination and location. My Toronto home is an ideal base for the last three items, the resort property on a mid- Atlantic beach is better for some others. As an aside, there is a beach in Toronto, we are on Lake Ontario, after all. Somehow it loses something in the translation though. Let's propose this for a four-day event.

There's only a few things missing, more coffee, more double espresso's, less sleep, less lectures (so we don't go to sleep). More building, more caffeine, more soldering, more expensive things to build, you might want to have your family/living room filled with people in sleeping bags. Toronto is a nice place, but that's a fair way for people in the west (like myself).

Tyborski >WebWerx >Milwaukee, WI Well, the simple answer is I didn't get my information from a web page, it was all from this mailing list. It came up as a topic of discussion a while ago, and I printed it out and filed it away in a notebook for later use. There is a web page that has all of the BEAM email letters on it since this mailing list started. It's at: http://www.webconn.com/mail/beam/ I think the letters that pertained to the neural neurons was called "Structure of Neuron (Nu) Layer" and "Re: Structure of Neuron (Nu) Layer". I recommend spending some time looking through a few of the letters posted there, and just looking at some of the topics that interest you.

Well as of yet, I have not built any of the BEAM circuits but I have experience with OP-Amp, and Timing Oscillators, where the outputs have to be exact. ( +/- 0.1%) To get high accuracy we use trim POTs. For example to get, say, 5K ohms we would use a 4.7K 5% resistor and a 1K POT. J.

But here goes: Capacitors (2 questions) 1. The Electronics Now article about BEAM bots lists C1 as 22F and C2 as 4700F. Seems like a BIG capacitor when most I've seen are measured in micro or pico farads. Misprint maybe? 2. The diagram on the page by Brian Bush calls for a 47000microF, should that be 4700? Transistors (3 question) 1.Elect. Now article calls for 2N2646 unijunction transistor. Can't find one in any of my catalogs (Mostly Mouser and JDR). Any suggestions 2.Lots of NPN and PNP transistors listed in the catalogs. Whats the difference between say a 2n3860, a 2n3866, and a 2n3904? All three are listed as NPN Gen purpose SS (whats the SS mean?). If you have an NPN in a circuit do you need a PNP also? 3. What is the difference between a PN2222A and a 2N2222? Diodes (2 questions) 1. Diagram from the lanl site has a mc4742 zener diode which I can't find in my catalogs. Found a zm4742 in mouser. DIfferent manufacturer? Any substitutions? 2.Another diagram I found calls for diodes of 1n4728 to 1n4731, can't find them listed either. Any suggestions or substitutions? SOrry I went on so long, but if you can suggest any further reference material let me know.

Because of the Nv Schmidt trigger IC, it works with signals from 0 to 2.5 volts. Higher voltages hold the process, or node, on. Although I have not tried it, the circuit should work with Sharp IR modules, too. Total cost: $1.00, or less, in common parts. Interested? Please let me know, and I'll try my hand at ASCII schematic drawing. I'll also write-up a circuit description and include notes from the BEAM e-mail archive. Cheers, Michael A.

The address for the company is at http://www.mirabilis.com The program runs in the background any time you are online and gathers any messages that you have waiting. It works by signing up at the web site and downloading the program. After that all you need to do is plug in new ICQ numbers as more people get on board. If anyone else is interested my ICQ is #1202916 and I will try to answer any questions that you may have, about electronics or BEAM robotics, if you find me online. This may be the solution to all the "chat room" ideas that have been floating around. The program allows you to page anyone else on your list who happens to be online at the time and have a realtime discussion. It also lets you send notices to other users to pick up when they come on line. The best part is that it is FREE. If we could get most of the BEAMers out there to use the program questions could be answered a whole lot faster for all of us. Let me know what everyone thinks about this.

I build the Bush solar engine last night using these components: 2N2907 PNP transistor 2N2222 NPN transistor (2N2222A should also work) 1N914 diode for setting trigger point (equ. 1N4148) 4.7K 1/4W resistor 0.1 Farad memory capacitor (I may change to a 4700 uF) General purpose circuit board with single-hole pads (What a pain..) I checked the circuit with a 1.5-3 V 120 mA motor (oh well) and a battery supply. The motor triggers when the capacitor voltage is about 1.8 VDC. If you use a good solar cell, Brian Burkhardt said he needed to increase the trigger point. Just wire two 1N914 diodes in series. BTW, your local electronics store sells all of these parts. I also found all of the parts on a 360K floppy drive. Try the circuit now and order competition-grade components later. Observations: As the input voltage increases, it gets held around the trigger point. Someone else on the BEAM list also commented about this. My motor did not run when I added resistance (or my Fluke multimeter in AMP mode) to the battery circuit. Since the motor draws at least 120 mA, the IR drop probably caused the circuit to fail. Let us know how your engine turns out. Michael A.

Onlookers may ask, "How do you expect two motors and a few sensors to behave intelligently?" Good question. After all, they've seen toys with many of the same components. Simple robots, however, can display many complex behaviors. And more important, they can behave as social insects like ants or bees. Here are two MIT web sites that show what inexpensive robots can do: Braitenberg Creatures http://lcs.www.media.mit.edu/people/fredm/papers/vehicles/ The Ants: A Community of Microbots http://www.ai.mit.edu/projects/ants/ Be sure to read the paper "Using Cooperative Robots for Explosive Ordnance Disposal." It's in PDF format and linked to this web page: http://www.ai.mit.edu/projects/eod-robots/ These papers show that none of us is wasting time or money by studying robotics. Together, we can have alot of fun while creating tomorrow's technology. Cheers, Michael A.

Now, you can get varible Cap.'s but they are more expensive, and not as commmon. As for range, I like to have around +/- 10% of my original desired value. This should be enough to offset the 5% tollerance of the resistor, and give a little playing room. But, not all of your circuits, remember, will not need to be this acurate. So don't go buying like a hundred little pots or somthing. Equation: 5% Resistor = Desired_Value - 10% (Pick the nearest Resistor value) POT = 2 x ( Desired_Value x 10%) (Round up to the nearest POT or POT = 2 x ( Desired_Value - 5% Resistor) value) J.

I'm not really the person to be asking about jumpers, I know nothing about them, and I never saw any jumpers there. The records for some events would be somewhat inaccurate, for example the photovore event. I saw around 6-10 year old kids moving around all the photovore's even though they saw the "do not touch, event in progress" sign. Right now I am feeling sorry for the people or teams who created the photovore's , because of the damage that their machines took in. Sure a photovore can take small hits, or more like taps, but when some kid is swinging a umbrella at a photovore to move it... The saddest thing is that I only watched the photovore's for about 2-5 minute's, imagine what happened during the few hours that I was not there. My notebook failed in a time of need, I woke up this morning to find that it was not charged. So I could not type it up, They where not even saying the competitors name or their robot's name, except for atomic hockey. It sounds from what I have wrote that the games was not a fun event to go to, but it is exactly wrong! The games where great no matter what few bad things happened, it's a lot easier to list any thing that was disappointing. Trust me, if I listed all the good things, this email would have been a lot longer, and that's not really a good thing. :) Devin Hyndman $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 882564A2.000F8588; Sat, 24 May 1997 19:49:32 -0700 Received: from gromit.webconn.com (root@gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id TAA09651 for ; Sat, 24 May 1997 19:38:07 -0700 Received: from mailgate.execpc.com (mailgate.execpc.com [169.207.16.5]) by gromit.webconn.com (8.8.5/8.8.5) with ESMTP id UAA06454 for ; Sat, 24 May 1997 20:53:50 -0500 Received: from mail.execpc.com (mail [169.207.16.2]) by mailgate.execpc.com (8.8.5/8.8.3) with ESMTP id UAA00803; Sat, 24 May 1997 20:53:30 -0500 Received: from LOCALNAME (linguine.mdm.mke.execpc.com [169.207.67.197]) by mail.execpc.com (8.8.5/8.8.3) with SMTP id UAA20093; Sat, 24 May 1997 20:53:25 -0500 (CDT) Message-ID: <3387A7F6.46F8@execpc.com> Date: Sat, 24 May 1997 19:46:14 -0700 From: "Michael A.

I'm planning to construct a walker from two RC servos and a four neuron MicroCore. The cycling is a little too fast. About 1/2 second. I'm using 1 meg resistors and .1 uf caps. I guess I'll change the caps to .22 uf. I did get the servo to rotate back and forth a little using two 74als245 piggy backed. I gutted the servos, and removed the electronics so that I can use just the motor and the gears.

Gimme a few days to clean up and recover. Autonomous sumo: a few guys got video tape of seeker VS a good robot with a forgotten name. The cure all hangover recipe: One Raw egg, 12 Strips of raw bacon, 2 slices of bread, one cucumber , one tube of hemorrhoid cream (no not for hemorrhoids, it's for your eye's), One blender, Lots of water, A bad headache, a box of Gravol(tm) , Some type of Ibuprofen, like Advil or Motrin IB. Instructions: Take the raw egg, 12 strips of bacon, 2 slices of bread, and make yourself some breakfast. Cut the cucumber into thin slices, and use as garnish for the breakfast. Put the hemorrhoid cream under your eye's if you have really "baggy" eye's, like the football players do with that black stuff, except don't try to get it all over your face. Drink some water, If you have a headache toss down some Advil, if you're nauseated because of eating too much breakfast or "something else", take some Gravol. If your scared of putting hemorrhoid cream on your face, don't do it then, I wouldn't even try it, my sister in law uses it to get rid of baggy eye's before a photo shoot, I think she's crazy for using it. If all else fails, smash your head through a wall, go to the hospital, and get some better painkillers.

A SCR is a single package designed to stay on when turned on. With the 2 transistor package, you can tune it for optimal performance (the bias resistor) depending on the application or motor. Also, you can substitute for larger power transistors (2n2222 NPN) and keep the smaller signal transistor (3906). And I'm not sure if there are any SCRs as easily available as the npn/pnp combo that run at such low power. >BTW. >Does anyone know about the compliance on those MPJA micromotors?

It works with input voltages that are between 0.7 and 3.0 volts. The transistor is configured as an Emitter Follower. As a result, it has these characteristics: 1. Vout is in phase with Vin 2. Vout is approximately equal to Vin 3. The input is high impedance and the output low impedance The node reacts normally to low Vin voltages. Once Vin reaches 3.0 volts, however, the node stays on. Basically, this circuit adjusts the internal threshhold points for the 74HC14 schmidt trigger.

I have been looking for a minimalist way of interfacing simple sensors (photodiodes, phototransistors, CdS cells) and effect the processes in a simple (say six to eight NvNeurons) NvNet loop and see how light or some other environment variable being measured can affect a looping process. Michael Tyborski's recent post looks applicable--being both simple and functional.

All we ask is you spend your hard-earned money to bring your BEAMbot out to Calgary and put yourself up at exhorbitantly-expensive accomidations, and none of you come out! ;-> Harumph. Makes a guy loose faith... Actually, besides the hard-core "BEAM-elite" that were out here for our annual build/drink/eat-fest, there were no other BEAM entries. And since none of us want to discourage less-experienced builders, we didn't bother entering our own creations (just displayed). I KNOW in the local area there are over 100 solarollers, and at least several dozen photovores, but none showed up this year! Well, except from the nice fellow from U of...Kansas (was it? sorry..) with the LM386 line-follower from this mailing list. (Who are you? Speak up - sorry we didn't get a chance to talk more and share dinner that night - you left too quick!) Anyways, compared to the previous year with a few dozen solarollers and a solid fistful of photovores and BEAM artwork, it was definitely a step down. We think it's time to start pushing for another EASTERN (ie: Toronto/Chicago/Minnisota) event with stronger population base. For offical results of _last_ years event, my notes show the winner in Solaroller had a final time of 1min6sec, with a fastest event time of 55 seconds by Scott Martin until his solaroller measured a fraction of an inch too high and was disqualified. Other than that, the WCRG event seemed to have lost some entries and attendance compared to last year. I think we (the WCRG executive) need to push advertising more. Also, some of the "old standards" didn't make it into the sumo event this year (I count at least 3 that were in various states of disrepair, including my own "Total ReCAB"). The firefighting contest was very interesting, with the fellow who started it in Connecticut (sorry, name on tip of tongue) coming out to see it too. There was a contingent of roboticists (20 STUDENTS!) from Manitoba who came out and competed in several competitions, and WALKED away with our R/C sumo championship (will remedy this next year...grrrr). Some very impressive, speedy designs. That's what happens when you team up the electronics dept. with the welding dept. Apparently, they "sold about a million boxes of candy" to pay for their trip out here, and it was well worth it. They had tons of enthusiasm and had a blast. Their presence really helped the spirit of the event. Will post some graphics to our website as I get around to it. Later, Dave -- "Um, no - that's H,R,Y,N,K,I,W. No, not K,I,U,U, K,I,_W_.

The difficulty is whether you conceive of a process as being a positive-logic thingy or a negative-logic thingy. Thus, the difference would be if you took the output through an LED to ground or if you went from Vcc through an LED to an output (respectively, including any required current-limiting resistors.) I hope I'm right in the following, but I'm not sure: the everyday typical microcore with only one process will show that process as a low (negative-logic.) As a result, you'd get the right results if your output LEDs were sourced from Vcc. There is a good chance that you are sinking the LEDs into ground, which would show "on" LEDs for 'quiescent' neurons and an "off" LED for the active neuron. Mark, etc.: is this more-or-less correct?
