Summary

This is the next iteration of my original sumobot design.

A few changes:

  • It\'s made from three pieces, not one
    *It uses two solarbotics GM8 gear motors (actually the pololu 120:1 equivalent), instead of continuous servos
  • It works.

I\'m really happy with how it came out.

UPDATE
I\'ve updated the files since I first posted this thing. They\'re pretty small tweaks but they really help when trying to wire up the whole thing and hold down the electronics.

I've posted a video of it in action. It still has no opponent sensing/detection but it's staying within the white space perfectly. See it here:

Stay tuned for thorough instructions/code and possibly a chassis kit for sale at botmade.etsy.com

Hi, really like version 2 of this little bot - I know this is kind of an old project now, but - quick question for you - the little IR sensors you have do you mind sharing where you found those? I've looked, and all I've been able to find are larger boards with sensors that look more like LEDs style. Thanks.

Have you considered altering the 90 degree overhangs to be more printer-friendly? And possibly teardrop shaped holes to avoid droop?

Thanks! I'm going to do a sumobot and print as much as possible, going to start with this but thinking of printing the wheels and some gears for it as well. Going to start with this and modify, will post what I come up with.
