Industrial robots and method for operating same

摘要

The robot (1) has a robot arm apparatus comprising a robot arm (6) mounted on a base. An electrical drive has a signal emitter for emitting a signal representing one of electrical currents and electrical voltages. A computerized control device (14) operates the robot arm by controlling the drive. The control device is supplied with the signal from the signal emitter and another signal from a position detector i.e. rotary encoder. The control device determines a position of one of axes (A1-A6) from the signals and controls the drive dependent on the position of the axis. An independent claim is also included for a method for operating an industrial robot.
