Abstract
Provided is a robot system with which it is possible to easily set an error parameter. The robot system according to an embodiment of the present disclosure comprises a robot, a measurement device attached to an end of the robot, a target mark fixed to a work space for the robot, and a robot control device for controlling the robot. The robot control device has: a parameter storage unit for storing a plurality of error parameters used to calculate the position of a reference point for the end of the robot; a command value generation unit for generating a command value indicating a required position or speed of a drive shaft of the robot, upon taking an error parameter into account; a position information acquisition unit for acquiring position information for the reference point on the basis of the relative position of the target mark measured by the measurement device relative to the measurement device and coordinate information for the target mark in a user coordinate system; and a parameter correction unit for correcting an error parameter on the basis of the command value and the position information.
