Re: Interesting/Cool Scaling Mechanism Designs

Here's FRC Team 1501 lifter in action (still action ):http://www.chiefdelphi.com/media/photos/43471
The hook design uses a spring to hold it back while we drive around the field. When we are ready to lift we use a pneumatic lifter to lift the hook to the bar. When it hits the bar, the spring over centers the hook and a spring pin keeps the hook from opening up as we lift. There are two pulleys for the rope.
Since the hook is loose in the lifter, we pinch the two ropes and the strap between the two lifter joint pieces.
The rope loop is attached to the front corners of the robot. When we lift we engage the PTO on our tranny. This reels in a ratchet strap that is attached to the rope.
We have tweaked it and it should be ready for the Indiana State Championships
