DEFINITION

Classification: 901/9

Closed loop (sensor feedback controls arm* movement):

Subject matter under cross-reference subcollection 2 wherein a sensor on the robot monitors a position of the arm* and transmits a signal indicative of that position back to the arm motion controller which compares the actual arm* position with the desired position so as to adjust movement of the arm* towards that desired position. [figure]

(1) Note. The arm* is controlled to move and to stop anywhere within its limits of travel, rather than only at the extremes.
