Re: Official Team 2526 Robot Model!!

Ryan, do a search on "class three lever". Just try to do the calculations on the middle elbow joint, ignoring the rest. It isn't too hard to "ball-park" it.

Better yet, borrow a bowling ball. Hold it straight down by your side, and have someone try to lift your arm and the ball by pressing up on the bottom side of your arm an inch or two below your elbow joint. That will give you an idea of the force necessary to raise that arm. You only have so much air pressure available. You can "super size" the cylinder, but you only have so much energy available in the compressed air tank and what the compressor can deliver on demand.
