Abstract

This measuring system comprises: a first measuring device that is attached to a manipulator and / or at least a portion of an end effector provided on the manipulator; a second measuring device that is disposed in a position spaced apart from the manipulator and / or the end effector, and that measures the end effector and / or the manipulator; and a control device that outputs a control signal for controlling the manipulator on the basis of a first output output from the first measuring device and / or a second output output from the second measuring device.
