The feedback control system that uses sensor data to correct robot motion errors is called ________ Control.

  1. Ethical / CEH
  2. du
  3. Uncertainty / Observer
  4. Closed-loop / Feedback

Answer: Closed-loop / Feedback

Closed-loop control continuously compares desired vs actual state (via sensors) and adjusts actuators to minimize error. Contrasts with open-loop (no feedback). Essential for precision tasks: assembly, welding, autonomous navigation. PID controllers are common implementation. Critical for robotics control theory questions.
