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.
