Pneumatics are excellent for motions that require two positions (one end and the other end), where the transition between the two positions must be fast, and where the forces required are not very large.

Understand how a rotary pneumatic actuator works. Basically, it is one (or two) small cylinders pushing an arm that rotates. Those small cylinders do not generate much force. So, for turning a small lever arm, they might be great, but for a large arm (like I might imagine for this year's game) you might be disappointed in the power. Check the specs to be sure.
