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.
