Great question. Human arms are also very bad in rigidity, repeatability, etc. but we manage to do great work by adjusting. Of course we try to move and rest on things to get out of the error-prone postures (so in effect moving from this to a gantry type of configuration), and need to measure, create jigs and templates, etc. but there is something here to be covered by sw for sure.

Comparing human arms to CNC "arms" makes about as much sense to me as comparing a sparrow to an F16.

Yeah both humans and multiaxis cnc machines can articulate their arm to apply a tool to a work piece and both a sparrow and an F16 can fly through the air.

I like your analogy, but just to clarify, which is the human being in your comparison: the sparrow or the F16?

A sparrow can take off and land on a branch, and it regularly weaves through thick foliage no wider than its wingspan. So, I assume the human is the sparrow?

Yeah I was thinking of the human as the sparrow.
