For motor testing on prototypes, we have some little 12 volt black and decker drills that we modified with a lead and anderson connecters. They work quite well and are small and portable. Since it is a drill, you can change the polarity easily too by using the direction control. Only downside is that they run out of juice fairly quickly. Another thing we did is have a passive bridge manipulator. We have a wide faced bot so our tower slides out to make an almost square robot for balance. The bridge manipulator is a drop down from the slide out that rotates back to make an inclined plane when we hit the bridge.
