Torsion Spring

Looks a lot like what we're trying to do.

That's pretty neat. I wonder how they plan to get down...

Looks like a regular hook so you just lift your bot off the tower.

Cool. Nifty way of lifting them up though. Very neat way to "pull down" and go up.

This Gives me a great idea! We don't even have to use a motor to pull ourselves up! Instead of having a motor provide that force to wind the winch up, we can use a stored potential energy. We could take a shaft and attach one end of surgical tubing to it. Then pull the tubing taught and roll it onto the shaft, and tie the other end to some sturdy peice. then, on the other end of this shaft would be one end of the winching rope. To lift, we just release the shaft and let it spin freely, which winds up the rope, pulling up the robot. All we need is like some sort of servo device to hold the bar still and then release it like a clutch.

Heh. Sounds a bit over complicated for a weeks worth. Plus that'd have to be ~120 pounds of force in a piece of tubing. Scary is that!

Or multiple tubings.
