Re: Impact and Capability of Motor Brakes?

If you have the weight for it, mechanical brakes will work wonders. It seems like pneumatics are the most popular, but motor driven brakes are possible. On our bot, we literally have COTS bicycle brakes on our center wheels. The cable from the brakes get wound onto a drum driven by a window motor, so they breaks stay where they are when power is cut because window motors are difficult to backdrive. For your situation, I would recommend pneumatic brakes, if you can package them/afford the weight.
