This is cool. Last Saturday there was a Space Elevator robot challenge, held in the Seattle area. Several teams competed to build Lifters out of identical Lego Kits. The objective was to climb a “Space Elevator” (a 7 foot long, 2 inch wide nylon ribbon) to deliver a “payload” (golfballs) to the “satellite” (a large brass ring).
Lots of pictures and videos at this website.
