Title:
CORRECTION FUNCTION-GENERATING DEVICE, ROBOT CONTROL SYSTEM, AND ROBOT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/163116
Kind Code:
A1
Abstract:
The present invention makes it possible to control the position of the tip of a robot arm with high precision without increasing the points for which the position is measured. A correction function-generating device (100a) for generating a correction function to be used for controlling the position of the tip of a jointed robot arm is provided with: an information-acquiring unit (110a) for acquiring temperature information measured at a specified position of the robot arm and a measured position obtained by measuring the angle of a joint at the time point at which the temperature information was measured and the position of the tip at the time point at which the temperature information was measured; a tip position-estimating unit (120a) for determining an estimated position by estimating the position of the tip at the time point at which the temperature information was acquired on the basis of the acquired joint angle; and a correction function-determining unit (130a) for determining a correction function, which is a function that has temperature information as a variable, on the basis of the results of comparing the measured position with the estimated position.
