Motors Don't Run

We know the motor works since if we directly connect the motor to the battery for very short periods of time, it spins.

Any suggestions?

Would you please go more into detail on how you are you wiring your bot? (starting from where it's getting power from and where it's all going). Load the default into the Robot controller and use PWM 1 and 2 (for the two drive motors), it should work if everything is wired correctly. We did have a problem where our radio wouldn't work, but after tethering and testing with it, everything seems to be fine.
