Arm is the next one I built. As usual, lots
more expensive than I thought it would be, but it is all mine (except for
the electronics, the servos, and the rest <grin>).
Arm was mostly a craft project. I went out to
the web and could only find a decent hint from the www.lynxmotion.com
site again, so I just eyeballed everything and made it out of 3/32" 5 ply
model airplane plywood cut with a Dremel scroll saw. The best thing I did
was to get it all working and then take it apart, paint the wood, and put
it back together again. It gave me a chance to tune it all up. The actuator
cable was adapted from model airplane parts (Golden Rod cable and aileron
eyes). I glued the ends of the cable tube into the claw housing using Epoxy.
The claw was thought up by me since the scissors claw on the Lynxmotion
site was just too hard to do with normal tools. This claw works pretty
well. See the AVI for an action shot.
Oh, yes... the electronics, right now, use the
Serial Servo Controller that you can get at Lynxmotion. The whole project
took about four evenings and a Sunday afternoon.
