Abstract
The present invention provides: a program generation device provided with a function to identify a robot movement causing an inconvenient voltage drop and present a movement for easing said robot movement or automatically ease said robot movement; and a robot control device. This program generation device comprises: an electric current calculation unit which calculates the value of a driving electric current to be supplied to a motor in order to cause a robot to operate in accordance with a movement program; a drop voltage calculation unit which calculates an amount of instantaneous drop voltage in an electric circuit between the motor and an equipment power supply for supplying an electric current to the motor, on the basis of the calculated value of the driving electric current and the configuration of the electric circuit; a comparison unit which compares the calculated amount of instantaneous drop voltage with a predetermined first threshold value; and an output unit which outputs a target movement or an easing movement in the case where the amount of instantaneous drop voltage has exceeded the first threshold value and/or a correction unit which corrects a target movement to an easing movement in the movement program.
