Abstract: The system developed by us consists of measuring head, target,and a subsystem for data collection and pro-cessing. Six displacement sensors of inductive type are mounted on the measuring head. The target is connected tothe robot under measurement. The data of target posture relative to the measuring head may be calculated inaccordance with the distances data from the sensors. A microcomputer supervises the automatic collection andprocessing of data, the communication and coordinating action between it and the robot controller. Actualmeasurements on two robots have revealed some results with certain significance.
