  • Patent number: 4734866
    Abstract: An optimum velocity controller having absolute track faithfulness for linear track motions of articulated robots having several axes of motion. If at least one velocity reference value of an axis of motion exceeds an assigned limit, the velocity of the predetermined total motion of the track is reduced. In order to obtain a stable control behavior of the robot, an additional velocity reduction of the track motion is executed for each of the individual axes of motion within predetermined range limits. The boundaries of these range limits are selected according to the respective velocity and/or acceleration of the robot along the track.

  • Patent number: 4665352
    Abstract: For reducing the dead time in the control circuit for the track control of an industrial robot (IR), a sensor signal (s) is fed back not at the interpolation clock frequency, but at the faster position control frequency. For this purpose it is necessary to transform the correction vector (c) derived from the sensor signal (s) separately into robot-referred coordinates (.DELTA., .alpha.) and to feed it back to the input of the position control. The actualization of arm position dependent transformation parameters (b.sub.mn) can take place at the interpolation frequency.

  • Patent number: 4616326
    Abstract: In a robot motion control system a modular sensor data preprocessing unit is provided between the sensors and a motion control unit. Modules in the data preprocessing unit are activated in a temporal sequence in accordance with the kinds of sensors involved and the technological task to be performed. The data preprocessing unit comprises a data transfer control circuit, a basic function control circuit and a complex function control circuit, each such circuit including a plurality of independently activatable function modules. For example, the complex function circuit includes a velocity control module and a path correction module.
