Sumo

So frequent readers of my blog (Hi Mom!) will remember my sumo robot competition coming up. The competition came and went and this is what happened. Last post I commented that if I had it to redo my sumo board again I would choose another motor driver IC. I spoke too loudly and Murphy heard me. After one failed repair job and one failed protoboard bot I finally got something working using the Teensy 2 and the TB6612FNG.

Sumo robots are pretty fun. Not to be confused with that robot show that was inexplicably on Comedy Central for some time. Sumo robots are small (generally) fully autonomous machines that have one simple goal. To push the opponent out of the arena. We also have a weight limit to deal with, for the small “Smart bots” like I’m building we have 1lb to play with while the larger ‘bots get a generous 4lbs.
