Summary:To provide a measuring system that can reduce time required in calibration and yet perform the calibration accurately.SOLUTION: The measuring system comprises: a plurality of reflectors 31a, 31b and 31c to be attached to tip parts of a robot 2; a measuring device 40 having a laser head 41 which emits laser light toward the reflectors and receives reflected light from the reflectors and a head driving device for changing a direction of the laser head 41; a robot control device 20 that controls the robot 2 on the basis of a calibration operation program by which the tip parts of the robot 2 are sequentially arranged at a plurality of measurement positions for calibration; and head driving control means that receives controlled coordinate data on any of the plurality of reflectors when the tip parts of the robot 2 are sequentially arranged at the plurality of measurement positions, and sends to the head driving device a control command for changing the direction of the laser head 41, using the received coordinate data.SELECTED DRAWING: Figure 1 【課題】キャリブレーションに要する時間を短縮することができ、しかも正確なキャリブレーションが可能となる計測システムを提供する。【解決手段】この計測システムは、ロボット2の先端部に取付けられる複数の反射器31a,31b,31cと、該反射器に向かってレーザ光を出射し該反射器からの反射光を受光するレーザヘッド41および該レーザヘッド41の向きを変更するヘッド駆動装置を有する計測装置40と、ロボット2の先端部をキャリブレーション用の複数の測定位置に順次配置するキャリブレーション動作プログラムに基づきロボット2を制御するロボット制御装置20と、前記複数の測定位置にロボット2の先端部を順次配置する時の前記複数の反射器のうち何れかの制御上の座標データを受付け、受付けた前記座標データを用いて前記レーザヘッド41の向きを変更するための制御指令をヘッド駆動装置に送るヘッド駆動制御手段とを備える。【選択図】図1
