  • Publication number: 20200238522
    Abstract: This robot controller causes a robot to follow a target, while a transfer device moves the target, by using a detection result obtained by a movement-amount detecting device that detects the amount by which the transfer device moves the target. When the value of any one of the speed, the acceleration, and the jerk of the target calculated based on the detection result obtained by the movement-amount detecting device or the pattern of the speed, the acceleration, and the jerk deviates from the predetermined reference, the robot controller performs predetermined reporting or stops the robot.
