My high school team 616 (no longer competes) created a successful scissor lift in 2005. It was powered by two Fisher-Prices motors that drove a lead screw. The amount of power needed to lift from starting position was so much that we propped each level of the lift up about an inch. And it was heavy, we were about 0.5lb under the weight limit. Picture attached below.

In all seriousness, scissor lifts are pretty difficult to get working, especially at a reasonable weight compared to elevators or arms.

Chris, just for you I've also attached a picture of our suction cups from 2004 in action...
