  • Patent number: 6230079
    Abstract: A method for control of an industrial robot, which has a plurality of movement axes with a position sensor for each of said axes which is adapted to deliver an output signal which defines the current position of the axis, and a control system for control of the axes of the robot. Continuously during operation of the robot for at least one mechanically critical point (i) of the robot, the relevant load (&tgr;i) during a predetermined period of time (&Dgr;t) is calculated on the basis of the output signals (&phgr;1,&phgr;2 . . . &phgr;6) from the position sensors and a mathematical model of the robot.
