The present invention relates to a control system for a servomechanism device such as robot, and more particularly to a position correcting control system for a servomechanism device which is well suited to perform high-precision positioning or high-perfomance operations on the basis of a sensor feedback control system such as force detection feedback control. It is characterized in that a plurality of algorithms for correcting a position target value on the basis of a sensor signal are prepared and are switchedly used so as to readily switch functions, depending upon whether the purpose of a sensor control is a high-precision control or any other high-performance control, that the position target value is corrected through a threshold characteristic element or a dead band element so as to make effective the correction of the position target value based on the sensor signal, and that a correcting signal is applied through a response lag element so as to attain stabilization owing to a viscous effect bestowed on the position correcting operation based on the sensor signal.

A control system and method for controlling a hand of an industrial robot are disclosed wherein the hand is driven at a predetermined speed along a polygonal path defined by a plurality of straight lines which interconnect a plurality of point coordinates taught to the robot. The straight lines are continuously interconnected by a parabola at predetermined locations in the vicinity of the centers of the straight lines, wherein the hand is continuously moved along the parabola from a straight line to the next straight line, and wherein the parabola is generated by dividing a span between two predetermined positions through arithmetic linear interpolation technique in a manner in which points located between the predetermined positions are defined on a straight line interconnecting the two predetermined positions.

Interfitting apparatus including a fitting jig formed with a plurality of regulating openings each for receiving therein one of a plurality of shaft members having chamfered forward ends, which are objects of interest, to hold the shaft members by regulating their posture and allow them to move freely within tight tolerances, and a table at least slightly movable in a horizontal direction for supporting, by precision positioning, an object formed with a plurality of holes separated from one another by a spacing substantially the same as the spacing between the regulating openings of the fitting jig. In fitting the shaft members in the respective holes in the object, the fitting jig is moved in a vertical direction toward the table, and guiding members and guided members mounted in the fitting jig and the table respectively are brought into engagement with each other so that the former may guide the latter, to thereby allow the table to move slightly in the horizontal direction to effect positioning of the shaft members and the object horizontally relative to each other within the range of the chamfers. Thereafter the fitting jig is further moved in the vertical direction to interfit the shaft members and the holes in the object with each other by exerting a fitting force on the shaft members from outside a jamming area.
