The goals
Hang on the bar
Do this in 10s or less
Fit on 14in tall robot

Proposed solution
Take two small Nerf (or similar) guns, and attach grappling hooks and steel cable. Hard mount these to your frame at the corners. At the start of endgame fire both dart guns at the bar. Then use 2 CIMs to winch yourself up 22-28in and hang there.

Does any one see any problems related to legality or technical implementation?
(Assuming the hooks stay within 15ins of the frame, and are throw at non lethal velocities)
