Re: Disk brakes

The controller senses when a wheel is beginning to turn and applies just enough current to the drive motors for that wheel to keep it stationary. This can work on each side of the robot in opposing directions to keep you from being spun around.
These dynamic brakes only work when you have power, so they won’t keep you on an inclined ramp at the end of a match. They are, however, lightweight (only software) and effective in keeping the wheels from turning. The limit to the staying power is the traction between the tires and carpet.

Would these potentiometers be made for continuous rotation, or am I missing something?
