Clever use of a servo motor
In Houston I found one team using a servo as a vacuum release mechanism for their suction cup. The servo was used to close or pinch off a piece of tubing thereby keeping their suction cup fully engaged. If necessary the servo would open the tube - releasing the vacuum. A clever and simple release mechanism.
Often servos are used as release mechanisms at the beginning of matches so that a robot can expand outside its constrained envelope.
