Vability of a particular climbing system

[xtantheta]

One of the members of my team suggested a pneumatic-run method of climbing: the bot goes in the inside of the 'mid, and slowly elevates itself using as many pistons as is feasible to push off the ground. A pole touches level 1, and a hook is positioned *above* level 2. The air is released faster than the acceleration due to gravity so the pistons retract, and the robot falls, but this hooking mechanism lands on level 2. Yes, it goes airborne for a split. It is dubbed "flying with style".

Now I know that we probably shouldn't use a coat hanger and duct tape for the hook, so I was wondering what was okay. Is a standard steal hook fine? Should we use more than one or two?

Many thanks for any and all help that you can give us. The more precise (and perhaps mathematical) the responses, the better.

Good luck to all the other teams in their goal of climbing!
