Is this using any feedback mechanism on the position, or is it just feed-forward?

Anyway, I want a machine like this that can paint.

There's a little bit of feedback: Each belt has a rotary encoder to track position, and the motors apply positive torque rather than positive position. This is in contrast to how stepper motors work on a 3d printer, for example.
