Two wheel drive robot ?

[jvriezen]

The OP stated a two wheel drive bot, with the rear wheels powered, but the omnis in front not powered at all. With scoring platforms and stray noodles, it seems any time you are on uneven ground (except when driving over a bump orthogonally) you'll have one wheel off the ground and this may reduce to a one wheel drive. With a four wheel drive, loss of wheel contact will only drop you from 4 wheel drive to 3 wheel drive.

Wouldn't this be a major issue?

Good point. What if you tried three wheels? That way you'll always have the drive wheels on the ground (unless, of course, you bottom out). One unpowered omni wheel in the back and two powered wheels up front may work.
