Two other techniques we considered for our ball pickup last year are:
- Make the frictional force low enough that when the game piece is fully in place, the wheel slips. Problems with this method include possibly reduced intake force and rapid wear on your rollers.
- Monitor the current draw on the motor and cut it off quickly when it spikes. This used to require custom current sensors, which we had purchased from pololu, but now they're built into the power distribution panel.
Last year we used our solution number one, as the balls were compliant and not much force was needed to pull them in; it may not be a good solution this year.
