The arm itself is working nicely so far. I have spring loaded joints to offset the load on the actuators. I am using rotary springs from car windows. The wrist is the bugger to build with the tooling and equipment I have. I am having trouble with the grabber binding on the common shaft. I think I have a solution finally. I am NOT giving up!</div><div>Hank</div></div></body></html>
