What does closed loop mean?
Control with measurement: read a sensor, compare with what you wanted, adjust, repeat. The measurement closing the loop is called feedback.
In a lesson
A program that says "forward for 3 seconds" and never looks is open loop: it acts and hopes. A program that looks at the sensors while it acts and adjusts is closed loop: what the sensors say feeds back into what the motors do. Every accurate robot is closed loop.
