Here is a quick video that shows my team's deployment system.

We still need to cut a channel in the Plexiglass for the pole and we need to figure out how the minibot will attach to the plate, but the core of the system is there. We used a pneumatic cylinder and a 4-joint scissor lift with the sliders. The mechanism goes from 0 (totally inside the robot's perimeter) to 22 inches (touching the pole) in about 1.4 seconds. The maximum extension, like I said, is 22 inches, which gives us some space for the channel and for alignment error.
