As for your second question -- the only motor that's spinning constantly is the Chiaphua motor. Even then, it's spinning at low voltage with a low current draw when the robots at the low end of its operating range. The drill can be safely turned off entirely once the robot's moved beyond the useful speed of the drill motor.

Actually if you don't cut power to the chip motor at low RPM it will stall and will subsequently over heat and literally fry the motor.
If you do cut the power to the chip it will act like a magnetic brake because it will be generating electricity; due to the conductor, magnetic field and relative motion between the two. That's assuming that the chip motor has permanent magnets.
