  • Patent number: 7925382
    Abstract: An input unit enters angular displacements by which drive shafts of a robot arm are to be turned as teaching data into a control unit. The control unit converts the input angular displacements into position-attitude data, namely, converted commands, indicating a position of the free end of the robot arm and an attitude of the robot in a rectangular coordinate system through forward conversion. The control unit corrects the position-attitude data on the basis of inherent errors in the robot to provide corrected position-attitude data. The control unit converts the corrected position-attitude data into corrected angular displacements through inverse conversion and gives the corrected angular displacements to an actuator included in the robot. The inherent errors in the robot include mechanismic errors resulting from machining errors and assembling errors, installation errors and errors in the origins of axes.

  • Patent number: 6701196
    Abstract: A control unit (14) makes an end effector (10) compliant with respect to an x-axis and a y-axis which are perpendicular to a z-axis parallel to a direction in which a shaft (20) is moved for insertion and makes the end effector (10) produce a pressing force acting in a direction parallel to the z-axis to press the shaft (20) against an internally toothed disk (22). The control unit (14) moves the compliance center of the shaft (20) along a predetermined groping route in a state where the pressing force acting in the direction parallel to the z-axis is produced by the end effector (10). The shaft (20) gripped by the end effector (10) repeats radially outward movement from a position near the center of the center opening (22b) of the internally toothed disk (22) in different phases in an xy plane defined by the x-axis and the y-axis to find a position where the splines (20a) of the shaft (20) are able to engage the internal teeth (22a) of the outermost internally toothed disk (22).
