Re: Crazy Crab

let me restate that even though Crab can be an amazingly awesome drive train from a mechanical standpoint, it is hell on your coders. design in the proper sensors (absolute encoders, gyro's etc.) and adjustments(chain tension and wheel alignment). otherwise you will never get it to drive the way you want.

BTW: 118 has a great pit display of their coaxial crab modules from like 5 years ago. Have them explain all the in's and outs of their system it's really cool. and if you look closely, it's not just the modules that make the magic happen, it's the whole system, the chain adjustment, gearboxes, sensors, and motor placement that make's crab an elegant solution to drive train mobility.
