Suppose I wanted to build a duplicate of this with slightly longer arms. https://en.wikipedia.org/wiki/Armatron I have one of these still in the original box and have played with it for hours. And then decades later my boys played with it. The TT Holders I use don't all have the slot like the original Tormach units. In fact 5 of the Tormach originals don't have the slots either. When I use my hand to catch the tool and place it in a rack I envision a robot arm doing much the same thing. In fact the same arm could theoretically serve a dual purpose and also place raw material and remove finished product. So 4 rotating joints and a gripper. Since it's not a rotary table under constant turning and precision is relative would 3D printed harmonic drives work for the joints? Or do they wear too fast. They don't need to be large and don't require tons of load capabilities. After all a TT Holder with a 1/4" chuck and #27 drill bit isn't that heavy. In fact I could probably pull the parts out of the collet with the Armatron.
