Re: Disk brakes

If you have potentiometers or a similar devices to measure the position of your wheels, you can program in a reactive braking feature that we refer to as “dynamic brakes”. When the robot is at rest and you want to stay put, the dynamic brakes are activated. 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.
