Speed of Atwood motors in forward and reverse...

The drills are probably still asymmetrical... Since it would make sense for a drill to be more powerful in "forward", or drilling direction. But this isn't too big a deal.

Just have more driver practice, and your drivers will be able to drive that robot straight. But if you really want to... Compensate the difference in the program, although you will be limiting voltage to the drills spinning in forward to match speed of the backward running motors...

Drivers' practice is still the way to go... You never know if you will need those forward running drills pushing as hard as possible.

Also, you can use the gyro (Yaw Rate sensors) to sense changes in drive train direction and program the robot to drive straight.
