1 cubic inch Robot

[Chief Pride]

thats really cool, is there a game u have to play with it? or is the challenge just making it work? :>

[basicxman]

did you use the motors found here:

???

Nice work... looks like you've done all your own surface mount soldering, and it looks like I see some reflective IR sensors on there.

You could fit... what, about 60,000 of those robots into the starting volume allowed for an FRC machine, or almost 6,000 into the starting volume of a VEX robot.

Now it just needs it's own teeny-tiny little shipping crate to get to Japan!

Nah, it would get lost before it would even leave the post office.

Those are incredible.

That's such a cute little 'bot... Looks kind of like the Japanese sumo bots we've played with in the past, except we didn't get to go to Japan.

So I'm intrigued by the photo and the whole notion of micro robots. I went to the site you listed for information on the competition. At the top of the home page it had a link to the construction manual for micro robot kit. Right on the first page of the manual was exactly what I was looking for. Right under the cutter knife and instant glue was the ever popular "insulting tape". And when it insults you, ir really sticks it to you!

See for yourselves at http://imd.eng.kagawa-u.ac.jp/maze/m..._manual_en.pdf

My guess is something got a tad lost in translation.

We're taking a team of 17 students and 4 adults to Japan this Sunday the 4th of Nov. We're very lucky to have an alumni of our school, Waiakea High - Team 2024, who went off to graduate in electrical engineering come back and help us. His employers at the CalTech Submillimeter Telescopes have been very supportive as well. Some of you have a very good eye...yes, we mounted the two circuit boards in a Horizontal position with two Geared motors and two wheels. We’re using a PIC16F877A for a processor. We have 3 IR sensors – one in the front and one on each side. The motors come from solarbotics - GM15 with a 24:1 planetary gear for about $15 each.
If you look at the website for the contest you'll see a 1 cubic centimeter robot contest as well. We're working on them now and I may have a picture up soon. They can be tethered so we don't have to put a pic on them. I had to special order motors from England.
The "game" for the 1 inch bots looks like a tic-tac-toe board with the lines being 30 mm wide, a little over an inch. You have to hit four points in the grid and then rush the finish line. For the 1 centimeter bots you have three contests - straight line race, slolom and hill climb. It's been a great experience with my students learning how to design,print and etch their own circuit boards, solder on very small components and programing. Let me know if anyone has more questions!

We also split up our team of 17 students into three different teams....In the end we were supposed to have 6 one inch micro bots and 1 cubic centimeter robots done by sunday. So far we have 6 running (motors running, not programmed) one inch robots and a built centimeter robot...we still have to tether the centimeter and practive driving it. Adding programs to our one inch robots will be some peoples priorities for the next 3/4 days.

[Lavapicker]

OK, we have a picture of our 1 cm3 robot now too. The nob on the front is actually a weight to help hold the shafts to the ground.

[Lavapicker]

The 1 cm robot is actually just a couple of very small motors glued together. We drive them on their shafts - no wheels. We'll be using very small mogami wire as a tether to the controls. The competition calls for a straight line race, a slolom course and a hill climb for these small bots. The ultimate would be to make these autonomous like the 1 inch robots. Maybe next year???

I'll dig up the article later but someone made a really sweet little flying bug. It was apparently pretty hard because the principles that make larger airplanes and helicopters fly didn't work on such a small scale.

Edit: Later means right now. Here's the article: http://www.technologyreview.com/Infotech/19068/page1/ and here's the metafilter discussion: http://www.metafilter.com/63135/Robo...sect-Takes-Off

Good luck on your trip Dale!
We are seriously thinking of joining you folks next year if your team and Art folks help us get there. Lucky Art! We just got back from Japan and he gets to go AGAIN!! By the way, your comedy performance last week was really funny. My students want more of your ninja act!
Take lots of pics!!!

[Lavapicker]

Team 2024 just got back from Japan last week with a first place in the one inch autonomous robot, a third place in the one cubic centimeter robot race and a fifth place and best bot award for the one inch remote control category. 3/4 of the teams were from universities in Japan, Korea and Guatemala. Check out the article, with a nice picture, below:

does the wire lead not count as part of the robots dimensions?

[Lavapicker]

The leads in the picture of the one cubic centimeter bot were removed and we ran just power wires directly to the two motors. Its a special wire called mogami wire (36 guage) with no memory - very limp. I have to say though that all the other teams were using this bare copper wire that was at least a 40 guage. I'm not sure where they got it but it looked like fine hair and we would have done much better with it.
For the one cubic inch robot, we also removed the leads and soldered the wires right to the board to make the one cubic inch rule. I expected to see a one-cubic inch box to fit in like the box we have at FIRST but when we arrived at the competition I was surprised to see that we were just on our honor. I thought there were a couple bots that actually exceeded the size limit by at least a half inch but I felt it would be too weird to pull out the ruler and cry that they're over by 5/16.
