Suggestion: Pallet Movers (i.e. forklift-type device)greenspun.com : LUSENET : Junkyard Wars : One Thread
How about a challenge where the contestants must build a device for moving cargo-laden pallets? The basic design would be a forklift, but certainly there are many possibilities for both power (gasoline, human) and lifting implementation (hydraulic, lever & counterweight, pneumatic, &c.). Judge by some measure of rate (lbs. cargo/minute over a fixed distance; pallets/min over a fixed distance).
