Patent number: 8036776Abstract: 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.Type: GrantFiled: November 14, 2006Date of Patent: October 11, 2011Assignee: ABB ABInventors: Magnus Hellberg, Mats Thulin, Michael Fors, Pierre Mikaelsson, Tommy Thors, Sönke Kock, Kevin Behnisch, Peter Eriksson, Jan Bredahl, Bo Toresson

Patent number: 6419211Abstract: A manipulator comprising a linkage with at least two links (1, 4) which have ball joints (3, 6) at their ends, and a spring device (10) which exerts a tensile force between the links. The spring device (10) comprises a first drawing device (11) with a first angle device (18), a second drawing device (12) with a second angle device (19), which are arranged, displaceable in parallel, side-by-side, and a spring member (13) arranged between the angle devices. The tensile force arises by the spring member exerting a compressive force against the angle devices.Type: GrantFiled: June 20, 2001Date of Patent: July 16, 2002Assignee: ABB ABInventors: Hakan Hvittfeldt, Jan Larsson, Pierre Mikaelsson, Fredik Persson
