A method for controlling a multi-axis industrial robot or manipulator arranged with a robot control unit. The robot or the control unit includes at least one first computer running a servo controller. A motion limit is configured for at least one axis of the robot arm. A reference signal for a robot position is sent to a robot controller together with a measurement of a position of the robot arm. The reference position is processed and the measured position and the processed reference position are then compared in an evaluator for the purpose of limiting the motion of an arm of the robot.

Method and device for controlling motion of an industrial robot with a position switch

An industrial delta robot with an arm system rotatable in space and including a base section, a moveable plate, several multi-jointed pull rods and a telescopic axle arranged between the base section and the moveable plate, opposite ends of the pull rods and of the telescopic axle being connected with the base section and the moveable plate respectively, and the telescopic axle comprising an inner axle and an outer tube arranged on the inner axle and displaceable in a longitudinal direction where a pair of end-to-end torsional rigid bushings are arranged in a stationary manner on the outer tube in which the inner axle is mounted to be displaceable, the bushings being spaced apart at confronting inner ends to form a transversely extending lubrication pocket for continuous lubrication of the inner axle during movement relative to the bushings.

Industrial robot

The present invention concerns an industrial robot according to the delta concept with an arm system ( ) intended for rotation in space that comprises a base section ( ), a movable plate ( ), several jointed struts ( ) and a telescopic shaft ( ) arranged between the base section and the movable plate, in which opposite ends ( ) of the struts and the telescopic shaft are connected to the base section and to the movable plate, respectively, and in which the telescopic shaft ( ) comprises a first telescopic arm ( ) and a second telescopic arm ( ) that are arranged longitudinally displaceable relative to each other, that each telescopic arm ( ) comprises at least two rods ( ) that are attached to holders ( ) at their respective end sections. The present invention also includes a method and an application.

Industrial robot device

A manipulator for an environment with hygienic requirements, comprising a stationary element ( ) with a plurality of drive means ( ), and arms ( ) attached to the drive means, which arms, via a respective linkage ( ), support a movable element ( ). The drive means ( ) are enclosed in an enclosure ( ) which encloses a gaseous coolant which, by a forced flow, takes up heat from the motors of the drive means.

Manipulator

A manipulator comprising a linkage with at least two links ( ) which have ball joints ( ) at their ends, and a spring device ( ) which exerts a tensile force between the links. The spring device ( ) comprises a first drawing device ( ) with a first angle device ( ), a second drawing device ( ) with a second angle device ( ), which are arranged, displaceable in parallel, side-by-side, and a spring member ( ) arranged between the angle devices. The tensile force arises by the spring member exerting a compressive force against the angle devices.
