4-wheel drive trouble

That shortens your running time and drags down everything else on the robot that runs off the battery. In the past (pre-backup battery) this would have reset the robot controller.

i agree.... we were having the same problem last year and probably this year too... that really helped us out...

another thing, think of different places that you can place pneumatics in of the robot which might help you to get up to the platform...
