Look at a 3D printer or some subtractive manufacturing machine like a CNC mill. There is:
- a workpiece holder of some sort
- a tooltip holder of some sort
- a frame connecting the two somehow
- actuators within that frame facilitating controlled motion that is minimally cross coupled
This sequence forms a kinematic chain.
And once the tooltip contacts-onto and presses-into the workpiece a loop is closed.
A progression in "expanding the loop"?
Regarding the bootstrapping of advanced atomically precise manufacturing one idea along the incremental path is to introduce a positional assembly loop quite early on and then scale it up.
Progression:
- Existing natural enzymatic proteins as example
- Catalysis construction kit approach (which includes the less ambitious functional block construction kit approach)
- Printer approach (See: Foldamer printer) (and less so robotic AP block handling approach)
- Full on advanced productive nanosystems
This "expanding the positional kinematic loop" approach pushes
the material capability technology levels pretty hard pretty early on.
So it's a quite direct side of the incremental path.
