Title: Industrial robot
Inventor: KASAI MASUO
IPC: G05B19/18
Filed: 1995-06-29
Abstract: PURPOSE: To make the quick conformity of position compensation and operation stability compatible. CONSTITUTION: Of the industrial robot which has an articulated arm, adjustment parts Tc1-Tc6 for time delay between position control servo systems Sb1-Sb6 and a robot track calculation part 21 outputs operation commands of articulations which are relatively short in response time among the articulations of the articulated arm with previously set time delay to compensate deviations in response time between the articulations. Further, position control servo systems Sb1-Sb6 select a small integral time constant when articulation operation is at a stop and thus quicken the whole integrating operation to compensate the influence of friction in a short time. When the articulation operation is not stopped, a large integral time constant is selected and the speed deviations are integrated to determine driving force; and then driving pressure when stationary friction is present is increased to stabilize the operation.
