Filed: 1990-03-27
Abstract: PURPOSE:To prevent the disorder of a production process and the lowering of yield caused by the interruption of work by dropping the work speed to terminate the work even if the work speed of a working robot is lowered during work because of the battery capacity approaching the lower limit level. CONSTITUTION:In case displacement delay is generated, the action of a handling robot 12 is not stopped, but the followable speed of each shaft motor is computed from the displacement delay quantity. On the basis of this computed displaceable speed, the target position displaceable per unit time is computed and corrected in order to continue handling action.
