Re: What drivetrain did you do?

Soap-Box style steering X 2.

Two pivoting axles, linked with a cross-bar to provide high-speed staight-away and turning. Each axle has a pair of CIM motors, driving inline 3:1 Banebots Planetary gearboxes and custom made 4" diameter traction wheels.

Original tests showed that we could drive and steer JUST using differential speeds on the opposing wheels, but we ended up adding a dedicated steering motor with position feedback for Hybrid mode.
