It looks a lot like a typical robotic arm used in manufacturing. A quick Google shows that there are a number of desk mounted versions available, but I have no idea what kind of accuracy they offer. It shouldn’t be that complicated of a design and since most approaches use encoders things like missteps should be a thing of the past.

I can’t see pulling this off at a home user price point without pretty big compromises on positioning accuracy and/or giving up on feedback.
