Abstract:
A method for controlling a multi-axis industrial robot or manipulator arranged with a robot control unit, the robot or the control unit also comprising at least one first computer (10) running a servo controller. A motion limit is configured for at least one axis of said robot arm. A reference signal (1) for a robot position is sent to a robot controller (13) together with a measurement of a position of said robot arm. The reference position is processed and the measured position and the processed reference position are then compared in an evaluator (4) for the purpose of limiting the motion of an arm of said robot.

Abstract:
An industrial robot including a parallel kinematic manipulator of an object in space. The manipulator includes a stationary platform, a movable platform for carrying the object, and at least three arms connecting the platforms. Each arm includes a first arm part connected to the stationary platform for manipulating the movable platform.
Abstract:
An apparatus, a method and a control system for controlling an industrial robot with at least one axis of rotation and/or translation. The robot includes at least one actuator or motor at each of the axes for driving a movement of an arm of the robot and at least one sensor at each of the rotatable shafts. A dither-signal generator for generation of a periodic signal is used to provide a varying dither signal to a servo of the actuator. Automatic adaption of the dither signal is provided. A computer program for carrying out the method and a graphical user interface.

Abstract:
A method of an industrial robot including a control unit and a manipulator including a tool including a defined tool center point and a device for determining a distance error between an inaccurately programmed position for a spot on a surface of a work piece and a corresponding actual position.
