TA>-J- Hi everyone, my first post to the beam group... What kind of inverters are you using? 74HC14s? The reason I ask is because I just got a two motor walker going as per the instrustions on A Miller's page a couple of days ago, using LS inverters. (all I had on hand). I had to use big Cs and small Rs (10uF and 5K) to get it to work. I also found it worked better if the electrolytics were connected with the -lead to the inputs. I figured the problems were from not getting a low enough low for the TTL chip. If I used resistors more than 7K or so my 74LS14 microcore wouldn't work. Probably no help at all since you are probably using the CMOS part.. I'm curious about how the solar walkers work too. ...jim --- ? OLX 2.1 TD ? I was going to procrastinate, but I put it off.... $AdditionalHeaders: Received: from dl.com by athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256453.004DE75D; Fri, 7 Mar 1997 06:10:55 -0700 Received: from gromit.webconn.com (gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id GAA08502 for ; Fri, 7 Mar 1997 06:01:36 -0800 Received: from internet-mail2.ford.com (internet-mail2.ford.com [198.111.80.24]) by gromit.webconn.com (8.7.6/8.7.3) with SMTP id HAA17789 for ; Fri, 7 Mar 1997 07:09:36 -0600 Received: by internet-mail2.ford.com id AB02070 (InterLock SMTP Gateway 3.0 for beam@webconn.com); Fri, 7 Mar 1997 08:10:28 -0500 Message-Id: <199703071310.AB02070@internet-mail2.ford.com> Received: by internet-mail2.ford.com (Protected-side Proxy Mail Agent-1); Fri, 7 Mar 1997 08:10:28 -0500 From: "John Anderson" Date: Fri, 7 Mar 1997 08:10:24 -0500 X-Mailer: Z-Mail (3.2.1 15feb95) To: beam@webconn.com Subject: Solar walkers Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii SMTPOriginator: janders3@ford.com From: janders3@ford.com Subject: Solar walkers PostedDate: 03/07/97 05:10:24 AM 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: 03/07/97 06:10:58 AM-03/07/97 06:10:59 AM DeliveredDate: 03/07/97 06:11:00 AM Categories: $Revisions: BlindCopyTo: CN=Laurence Mayer/O=DLNOTES/C=US Written previously: > Also I had a question about the solar Nv walker.

The ceramics are probably in the nanofarad range, causing it to go waaaaay too fast! >Also I had a question about the solar Nv walker.

Some _can_ run continuously, but they're usually wired to have a dormant stage even if there is more than ample light. This lets the walker have an extra "boost" occasionally - something useful if a leg is stuck and needs some extra *oomph* to move it out. >If they do Store and Dump is the Microcore self >stabalizing ie it takes a couple "learning steps" and then walks from >there. Maybe I am confused? Nope, you've got it. So far, the solar walkers have been simple 2 motor devices (for power efficiency, less motors the better!). These usually require a simple 1 process pulse running thru the net, so it's really quite easy to inject the single pulse, and let'er run. Later, Dave -- "Um, no - that's H,R,Y,N,K,I,W.

Since you've usually got two extra inverters left on the chip after making your 4 neuron net, you turn these into a long duration timer (simple logic circuit - any decent electronics book shows you how with two inverters). After the timer expires, it dumps the signal thru a diode to a neuron of your choice, and a-waaaay it goes! Of course, this turns it into a combo type-1 and type-2 circuit.

The Nv circuits I've built have always powwered up fully populated with processes. I have to this point used another inverter to automatically kill the unwanted process, and leave the loop with only one. This leaves me with only one free inverter. Am I doing something I don't need to? The powwer to the 74HC14, shouldn't this be isolated in some way? I've built a solar roller based on a 3909 led flasher this way. Connect a small cap through a diode to the main storage cap, and use the this to powwer the 3909. That way when the circuit fires, the 3909 keeps time. > Of course, this turns it into a combo type-1 and type-2 circuit.

In order for you to get an answer from any of them, you will have to address your questions to them a little more specifically. There are some other things that you will want to ask yourself, before you ask the people on this mailing-list: -Is the kit apropriate for my ability? -Are extra tools requires to build the kit? -How much will the kit cost? -How much do the tools cost? Also, you may need some help ordering a kit. It usually requires a credit card or cheque, and as a fourteen year-old, you might not have access to those yet.

It was based on a gyro spinning about the lateral axis, with the legs outboard of the gyro. When one of the legs was lifted, the 'bot would try to fall over, but because of the precision ( sp? ) built into a gyro, it would rotate about the verticle axis instead; swinging the "up" leg forward. When the other leg is lifted, the force on the gyro is reversed, so it swings the other way about the verticl e axis. Tada!! it walks.

John-- I think you are referring to "Gyroscopic Procession", which is the effect whereby the reaction to force on the gyro's plane will occur 90-degrees about the gyro axis from where the torque was applied, in the direction of the rotation of the gyro. It is the same effect that causes a wobble about a gyro axis. In my R/C helicopter, all of the controls affect the rotor 90-degrees (sideways-sort-of) from where one would intuitively expect if you follow the linkage with respect to the joy-stick. This is because the rotors act 90-degrees ahead, causing the torque on the gyroscopic plane to be 90-degrees from where you would want the reaction to be. The gyroscopic procession effect causes the helicopter to react in an equal reaction 90-degrees about the rotor axis, in the direction of the rotor spin, correctly moving as the joy-stick control points. Anyway, the application in a biped is really slick, I like it a lot.

I didn't and don't have enough electronics knowledge to get into the microcore stuff. So I built a light seeking robot with a Basic Stamp. I am trying to make it all solar powered. The Stamp can run off solar power easily, but the motors are another story. Outside they are ok, but I need to adapt the capcitor charge up cirucit used in the basic type of solar engine. I want to be able to charge a very large capcitor or capcitor bank and once it has enough power two run the motors for a second I want to discharge it. The onlt thing is I want the Stamp to be able to control all of that. So that maybe I could charge one Cap wihile I use another. My motors will run at about 1-3V @ .3-1A. I made a very effecient H-bridge so that I have a very little voltage drop. I don't know where to start? By the way, I am high school senior and am taking this project to the Intel sposered International Science Fair. Anyway, I need alittle help............thankyou very much!!!!

Using electrostimulation of legs and heat sensors, they send these roaches down into building rubble to look for survivors. They cannot make the roach start or stop, but once it starts moving, they can control his direction. I've only been able to connect to the site once. Usually the server is down. Come to think of it, I haven't had much luck connecting to japanese sites on a regular basis. Anyway, it's worth the effort once you can connect.

Nothing like seeing your "Creature" take it's first steps, eh? I like to think of that as the "Mad Scientist Moment" :-) Now, about your questions. All of the things you have suggested are possible. You can make one of a variety of simple circuits to have your Stamp control your charging circuit, and have all of that run your motors. That, however, is not very BEAM. . . It might be worth doing, just for the reaction of the Intel Adjudicators, though, when you tell them it's a non-intel product running the show. (You rebel !! ;-> ) Here is a little something to try. (Disclaimers first: I haven't wired this up, and I don't know how much current you need to keep the Stamp running. You are really on your own here.) 'Nuf said. +---------+----------+-----|>|-----+-------+ | | | Diode | | Solar Big C | Not so Stamp Cell for motor H bridge Big C and etc. | | and motors | | | | | | | +---------+----------+-------------+-------+ [wow! ascii-art: I'll try not to do that again, it scares the kids.] Okay, first time out, nothing is running, Big C starts to charge, Not so Big C starts to charge at that level minus the forward Diode drop. (your H bridge _Does_ default to "off", Right?) Not so Big C charges to the point that the Stamp "wakes up" and starts to check things out. Now your clever porgramming takes over ( and I'm off the hook. ) You let Not so Big C charge high enough to sustain the Stamp during the Big C discharge and recharge cycle. This continues until you win first place :-) ( You will, of course, mention the "BEAM-List" in your Bibliography ?!?!) Way, way, way, good luck. Now if you wanted to do this a slightly more BEAM-way . . . The light-seeking photovore circuits are a ton of fun, and not very complicated. If you want to start very simply, because you are shy about the electronics, do a Solar-Roller. It's really just half of a photovore, and the circuit as about as simple as the power supply circuit you make for your Stamp. [Let's keep 'working' on Brian, we'll have him converted in no time.] Again, best of luck with the current project. You are on the right track, in that you have built _something_ (anything) which is tons better than just thinking, and wishing. . . Let us know how the project goes.

"Still", said Dr. Frankenstein, "that idea's not _all_ bad." _Scientific American_ (I think) had a report on the biological strain gauges that 'roaches use in their gaits.

The latest issue of New Scientist has an article on these bionic roaches or Robo Roaches. Seems a guy at Tokyo University has strapped a backpack containing electrodes that stimulate the roach's antenna (sp?) and can control its direction. It basically looks like they are hardwiring a control circuit into the roaches nervous system and overriding the roach's control signals from its brain. They did do this by stimulating the roach's pheromone sensors so that it thought it was chasing a female (poor guy!) but now the've wired it to its antenna. The trick now is to get the roach to stop on command, starting it is no problem, anyone who gets a few volts to a senstitive part STARTS MOVING FAST! I like this idea of instead of building an artificial nervous system in a BEAM bot to use a nervous system that is easy to control and which has evoleved over millions of years plus they are nearly indestructable! except to a well placed foot. I have to agree with the other guy, I won't be experimenting with roach's either..too messy :) Anyway New Scientist has more info if you want to look at it. On another point. Robotix 97 was excellent if a little too crowded with KIDS! Its like being surrounded with hundreds of BEAM bots that like to poke,prod bite and eat everything in sight. As Mr Miller can testify "Can you please not touch that please.." :) "Can you please not touch it..." :] "Can you not touch it.." :( "DONT TOUCH!!" :# Thanks Andrew for showing your bots off, I liked the idea of removing a random component (?) from the snake bot and it still works in a different behavior pattern. I hope more BEAM events will happen in our BACKWATER TOWN...

Last April we had a great contest. People came from all over to compete, participate, watch, learn and enjoy. This April, the contest will be even better. The goal of this contest is to build a Robot that can find and extinguish a fire in a house. The challenge for the entrants is to build a computerized (not radio-controlled) Robotic device that can move through a model of a single floor of a house, detect fire (a lit candle) and then extinguish it. Robots that accomplish this task in the shortest time win. This day-long international event will culminate months of work and effort by Robotists of all ages. Last year's contest drew interest from people in 46 states and 13 countries, and participants ranged from college professors and engineers to elementary school students. Participants last year included MIT professors, high school students from Canada, rocket scientists from Florida, a toy designer from Los Angeles and a 4th grade girl from New Jersey. CONTEST WEEKEND SCHEDULE All events are held on the Trinity College campus and are open to the public Contest Schedule: Saturday, April 19 9 am to 8 pm - practice session open to public & Robot registration 12 noon to 3 pm - display of inventions by Connecticut students 1 pm to 5 pm - Robotics seminars and demonstrations 6 pm to 7 pm - open hospitality party for meeting people & sharing ideas Contest Schedule: Sunday, April 20 9 am to 12 noon - practice session and Robot registration 1 pm to 5 pm - the running of the contest and awarding of prizes Robot Fair - Bring equipment, literature and brochures to demonstrate, show-off & pass out. Register now for your free table space. Building a Robot? If you are entering a Robot, be sure to mail in the official registration form along with your $20 registration fee. Jake's Pet Peeve - Every year Jake gets messages from people who said they built a Robot, but since they knew it wouldn't win, they didn't come to the contest. WRONG! The real goal of the contest is to learn and have fun. You can't do that sitting at home. No matter what your Robot does (or doesn't do), make sure you come to the contest. $AdditionalHeaders: Received: from dl.com by Athena.dl.com (Lotus SMTP MTA v1.05 (274.9 11-27-1996)) with SMTP id 88256461.007B433F; Fri, 21 Mar 1997 14:26:21 -0700 Received: from gromit.webconn.com (gromit.webconn.com [206.42.142.5]) by dl.com (8.6.9/8.6.9) with ESMTP id OAA20756 for ; Fri, 21 Mar 1997 14:17:03 -0800 Received: from huey.cadvision.com (huey2.cadvision.com [207.228.64.2]) by gromit.webconn.com (8.7.6/8.7.3) with ESMTP id OAA25894 for ; Fri, 21 Mar 1997 14:46:23 -0600 Received: from Solarbotics (ts39ip129.cadvision.com [207.228.71.129]) by huey.cadvision.com (8.7.5/8.7.5/DCX/TRI) with SMTP id NAA74088 for ; Fri, 21 Mar 1997 13:45:38 -0700 Message-Id: <3.0.1.32.19970321134917.0070cc34@cadvision.com> X-Sender: skip@cadvision.com X-Mailer: Windows Eudora Light Version 3.0.1 (32) Date: Fri, 21 Mar 1997 13:49:17 -0700 To: beam@webconn.com From: Dave Hrynkiw Subject: New 3.3V buffer chips - solar walkers, anybody?

Lower quality tools do not last as long as higher quality tools. The correct tool, used properly, does a much better job. You'll need some basic parts: You can salvage working parts from broken or discarded consumer items. (VCR's, camcorders, stereos) Parts can be had cheaply at surplus shops. You've mentioned Radio Shack, so you know about their blister packs. There are many full-line electronics distributors that will mail you a free catalog; place an order with them, and choose the delivery speed you need. You'll need some basic ideas: The mainstream electronics magazines usually have a 'beginner level' construction project, or two in them. These websites: http://www.solarbotics.com http://www.golden.net/~amiller http://www.xs4all.nl/~sbolt have lots of photos of completed BEAM robots. Solarbotics sells BEAM and BEAM-related parts and kits. (You would scream if you could see what he has in the prototype stage! :-) Learning electronics is easier if you are building while you are reading. So, use the books as a reference.

Get a sturdy, solid, closeable container. Whenever someone gives you a broken VCR (etc.) take it apart and put the pieces in the junk box. If your initial junk box is stackable, so much the better, you'll be compiling (and piling) them very soon. The junk box is your first source for parts. Need a motor; get that dead portable tape player. Storage capacitor? VCR. . . Cheers, Richard.

So, what I'm asking you (and perhaps some intrepid Web page owner) to do is to start a page or two with the information you've offered, like: > You'll need some basic tools: > Tools do not last long if they are misused >or abused. Lower quality tools do not last as long >as higher quality tools. The correct tool, used >properly, does a much better job. Which really is good stuff, might be found in a book or magazine but often those aren't available to some people (out-of-print, don't have the money or whatever,) and web-publish those in the simplest manner possible. Now, I realize that there is at least one FAQ-style page out there somewhere: perhaps it would be best to add advice like yours there.

(I know it gets old having people ask the same question over and over). anyway I got my solar engine to work, but it is not what I expected. under a desk light it takes a long time to spin the motor alittle. Sometimes it will reach right before the trigger voltage (about 1.8V) and not charge anymore, unless I move the light closer. I a useing the basic solar roller circuit. and here are my parts. 1. PNP transistor 2N3906 2. NPN transistor 2222A 3. 3 1N914 diodes in series 4. 2.5 volt solar cell from Sanyo (off a calculator) 5. 16V 3300uf Cap 6. discmen mubachi motor ( can't remember how to spell it) I would like to optimize this as much as possible, so please suggest anything you mught think would help. Also, I want to make this on a larger scale with small geared down motors. Can this be done without having to wait all day for the Cap to charge. Also, I would like to have a few seperate circuits charging at once and dumping thir power one aftr the other, to speed the robot up..... Can this be done. If you couldn't tell I am new to electronics, so bare with me. Despite this, I have built my own like seeking robot (Batt powered) with the Basic Stamp II. I would like to implement this method of storing solar power for and then dumping it for this robot's motors. Hopefully I can get it to run off solar power without using rechargable batteries. After, I finish this project I am going to build a real BEAM robot. I really need help so, if anyone can help ( with suggestions or places to look for info) please respond.

If you put those cells in series, as a 0.8A 2.0V you'll have plenty of current. You might not have enough voltage to get the flashing LED to trigger. On the other hand, with those cells, you might get it to run the motor directly! They must be fairly large cells, eh? As to the BEAM book, the rulebook section is crucial if you plan to enter any BEAM sanctioned competitions. The photos and circuit ideas are very helpful. Besides, ongoing sales might just encourage Mark to put out another book, sooner. . . Good luck, and let us know. . .

It's a TO-92 device (transistor shaped), left leg = trigger, Middle leg is positive, right leg is negative. Remove the diodes or FLED from the traditional solarengine and put the trigger from the 1381 to the BASE of the 3904 (middle leg). Also, try strapping a regular diode across the motor. Apparently, the back-emf from the motor can cause some problems, and this diode will quench it. Other ideas include better light gathering devices, like tinfoil reflectors or Fresnel lenses over the solar cell. Panasonic also makes some tremendously large capacity capacitors (multiple farads) called their Gold Series. They may take too long to charge for your purposes, however. But once they do, zooooooooooooom.... Scott A. Burns, Associate Professor Department of General Engineering University of Illinois at Urbana-Champaign 104 S.

[snip] Now that you have a basic circuit working, put it into a SolaRoller. There will be mechanical problems to deal with too. The whole design starts to get totally non-linear now, too. An example. My previously successful roller gets a motor transplant. Brand new high-efficiency (and cost) but does it ever look great on the 'bench. Pop it in the Roller . . . Ooops, I guess that extra three grams of motor mass is what keeps it from moving at all. Let bump-up the Capacitor value and move to a longer charge time. Okay, it moves now, but the zero to one-hundred (centimetres) time was better with the less efficient motor!?!?!? [Wow, ramble ramble, Richard.] Anyways, I think the next step is to change from spinning on the breadboard, to rolling across the table. ************************************************ *** Important safety tip: Have a permanent *** *** corral, or "Robot Jurassic Park" that the*** *** Roller CAN NOT escape from!

The diodes I am using are just basic switching diodes. I had to put 2 in series for the solar engine to work, I palyed with the number and 4 seems to work the best. It triggers at about 2.3 volts. In full sun I get maybe 6-8 little jerks of the motor in one minute. I did build it into a roller..... sort of a small circuit/capcitor/solarcell package in between to big wheels. The motor has a small gear on it that turns a planetry gear on the wheel. This engine was to test and see if I could use this sort of circuitry on my larger Basic Stamp robot. Maybe, having three or so solar engines all cahrger at once and using one at a time so I could get a more steady motion. I realy liked building it......I didn't buy a thing......just took apart some old toy cars and such. I really like the whole idea. Where is the best place to start to make a BEAM robot that will seek light? Also, the engine works fine in the sun, but in side under my 75 watt desk lamp it will charge right up to 2.2 - 2.3 volts ,but not trigger, Then I have to move the light closer to get it to go. I thought that it would keep charging. Even in dim sun light it will charge to the trigger voltage and not trigger until the sun comes out more. What is happening? Thanks again!! -----oh ......my small bot almost took a fatal flight off my desk when I left it along to long....pretty crazy!! ----Brian B.
