If you're talking about VRC, Team 1103 (Titan) has easily the best robot that can both score/descore and high hang. Check out this thread on vex forum: http://www.vexforum.com/showthread.p...highlight=1103

Eric,

The key to a simple, yet fast high hang lies in the use of an extremely strong elevator. To maximise efficiency, this can be put on the same arm that is used to pick up rings, or a separate elevator on the back of the robot.

KISS should be applied when you design this prototype. The simpler the better.

Best Regards,

Austin

What our team found this year (355A) was that our claw arm wasn't enough power to lift up. We had a four bar with 4 296 motors, but found that although they had enough power to just about lift the robot up, it would back drive once it was all the way up (although our robot this year weighed 19.6 lbs!). We added a winch kit to each side with a 393 motor on each one and it was plenty of strength for a high hang, and the ratchets on the kits kept it from back driving. Unfortunately our team wasn't able to pull off hanging before our regional because the way the winch's were positioned, the string would run into the claw when it folded back. Also a certain other robotics team got in the way come January too...
