Re: Re: OTHER than "cooling breakers", what do you do?

I'll go check those out. Holonomic drives are pretty cool... Thanks!

BTW... Omni-Wheels are only ONE way of doing a sideslip wheel. It doesn't have to be VERY slippery side to side, only significantly MORE slippery, enough to manage the turn scrubbing forces without sacrificing too much forward and back drive traction.

Another simpler example than homebrew Omni-Wheels might be treads made from repeated slices of inverted U channel bolted to your wheel or tread. If the inverted U can be seen looking at the side of the robot (align from side to side), AND the side to bottom edges of the vertical pieces have a radius on them (rounded, so it looks like a "U" from the front), it makes for good claw traction forward and back, yet acts like a sled runner if shoved sideways. Any slide push causes it to "climb the carpet nap" and slide easily.

Any other SIMPLE methods of making "side slip wheels"?

Remember, this thread is about ANY technique to reduce breaker blowing. Not just wheels, chilling, etc...
