摘要： The controller comprises (a) an interpolation calculator for dividing move data of a robot arm tip position into each sample period, the data fed from a position teaching section, (b) a load inertia calculator, (c) a gravity torque calculator, (d) acceleration and deceleration (A & D) time calculator for calculating an optimum A & D time by using the load inertia calculated by the load inertia calculator and the gravity torque calculated by the gravity torque calculator, (e) an A & D processor for providing an A & D process to move data of each sample time calculated by the interpolation calculator based on the A & D time calculated by the A & D time calculator, and (f) position controllers for controlling each motor based on the move data processed by the A & D processor. The A & D time is calculated with the following equation:T=.alpha..multidot.(J.sub.m +J.sub.L)/(T.sub.m -T.sub.L).multidot.Vwhere: V=desirable speed, J.sub.m =motor inertia, J.sub.L =load inertia, T.sub.m =motor torque, T.sub.L =disturbance torque including gravity torque, .alpha.=proportional coefficient and T=A & D time. The robot having the above construction can figure out an optimum A & D time by considering change of load inertia and also that of gravity torque produced by a posture change of the robot, whereby A & D time can be varied. As a result, the robot can be operated at a higher speed.

摘要： When either a command value or an actually measured value is appropriately selected as an angular velocity used for the frictional torque calculation, the frictional compensation can be made valid at all times in both the case in which a robot is actively operated according to an angular velocity command and the case in which the robot is passively operated being pushed by an external force. In the case where a motor rotating direction and a collision direction are reverse to each other after a collision has been detected, the control mode is switched from the positional control to the electric current control and a torque, the direction of which is reverse to the direction of the motor rotation is generated by the motor, so that the motor rotating speed can be reduced and the collision energy can be alleviated. After that, when the motor rotating speed is reduced to a value not more than the setting value, the control mode is switched to the compliance control and the distortion caused in a reduction gear is dissolved. On the other hand, in the case where the motor rotating direction and the collision direction are the same, the control mode is directly switched from the positional control to the compliance control without passing through the electric current control. When the robot is operated whole following a collision force, the collision force can be alleviated.

摘要： A control system which comprises a reduction gear unit containing gears, a motor being disposed on an input side of said reduction gear unit, a sensor for detecting a turning angle of said motor, and control means for inputting output from said sensor and controlling turning of said motor. The control system further includes gear output angle variation estimation means for estimating a gear output angle variation of said reduction gear unit based on the motor turning angle. An angle transmission error is estimated based on the motor turning angle, whereby load tip locus accuracy can be improved without lowering responsivity of the control system.
