Re: Four Little Motors
Make sure they each motor on your gearbox is turning the wheels in the same direction manually: one motor at a time, touch the black to back and red to red on a battery. If they are not turning the wheels in the same direction then reverse one of the polarities on your speed controller.

Also, we had a weird stalling issue with our drive train this year when we tried to move them at more than a slow turning pace (with the robot on blocks). Turned out it was caused from a bad battery.

Also, if you are using 2 motors on each gearbox, I recommend using one motor output for each side and making the PWM cable into a Y cable so you know that both motors are always being driven at the same speed.

Hope it helps.
