Go to Post It doesn't make a team better if they have just one sponsor or if they have 100 sponsors. However, you should commend a team who struggled to pay the bill with a list of sponsors one hundred long for showing their strength, perseverance and love for participating in the FIRST robotics program. - MikeDubreuil [more]

I have been thinking about a solution to this also. We won't need to use it due to redesigns with our arm drive but I think a good solution is to make a centrifugal brake. If the motor shaft is extended long enough, a pair of arms with weights connected to the shaft can be used to compress a spring. So, when the motor is not running the spring can press on a friction material holding the motor shaft. When the motor starts to run the mass of the weights swing out due to centrifugal force compressing the spring.

You’ll have to work out the forces needed, but I think this basic idea has merit.
