Sounds like Alan has it pegged....carpet makes a big difference in high gear turning ability. Also go thru the electrical supply system completely, the screws that hold the wires into the distribution block and the Maxi Fuse panel need to be TIGHT, and have enough bare wire (correct strip length) to be fully inserted. This bit us at the AZ regional, the robot worked fine at home, but had all kinds of weird problems like you describe, ending with it sitting still on the field during our last elimination match (which we lost, of course). Inspection at the next regional revealed a loose and melted wire at the fuse block, replacing it and tightening all the connections properly resulted in no odd behavior during that regional.
