Abstract
Official abstract text for this publication.
A measurement system including: reflectors mounted on a robot; a measuring apparatus including a laser head, wherein the measuring apparatus includes a controller, the controller is configured to conduct: a coordinate relationship acquisition process for acquiring a position and a direction of a measuring-apparatus coordinate system with respect to a robot coordinate system by emitting a laser beam from the laser head toward reference reflection portions provided in a base portion of the robot, and based on a reflected light; and a head drive control process which controls a direction of the laser head by receiving coordinate data of the reflector recognized by a controller of the robot, and by making a control command to change the direction of the laser head using the coordinate data which is received and the position and the direction of the measuring-apparatus coordinate system with respect to the robot coordinate system.
First claim
Opening claim text (preview).
1 . A measurement system comprising: a reflector mounted at a distal end portion of a robot; and a measuring apparatus including a laser head which emits a laser beam toward the reflector and receives a reflected light from the reflector, and a head driving device which changes a direction of the laser head, wherein a position of the reflector mounted at the distal end portion of the robot is measured by the measuring apparatus, wherein the measuring apparatus comprises a controller, the controller is configured to conduct: a coordinate relationship acquisition process which acquires a position and a direction of a coordinate system of the measuring apparatus with respect to a robot coordinate system, by emitting the laser beam from the laser head toward a reference reflection portion provided in a base portion of the robot, and based on a reflected light from the reference reflection portion; and a head drive control process which receives, from a control unit for the robot, coordinate data of the reflector, which is recognized by the control unit, the reflector being mounted at the distal end portion of the robot, wherein the control unit transmits, to the head driving device, a control command to change the direction of the laser head using the coordinate data which is received and the position and the direction of the coordinate system of the measuring apparatus with respect to the robot coordinate system. 2 . The measurement system according to claim 1 , wherein the reference reflection portion is used for setting the robot coordinate system when installing the robot.
