Real motor curves and SI units. Give each person a different assignment code and they each get their own mechanism to tune.

Push, proportional to how far off it is.
Grinds out an error that won’t budge.
Brakes. Amplifies sensor noise.
Holds the arm’s weight up front.
This arm is tuned badly. Look at the response curve above — what is wrong with it?
Drag a slider — the test runs itself.
