Abstract: A robot controller is a robot controller that couples a three-dimensional measuring device configured to perform three-dimensional measurement of an object using a laser beam and a human detection sensor configured to detect a person based on an image obtained by imaging a detection range including the object, the robot controller including a human detection signal receiver configured to receive, from the human detection sensor, a signal indicating that the person is present within the detection range and a robot arm controller configured to control a robot arm based on the signal. When the human detection signal receiver receives, from the human detection sensor, the signal indicating that the person is present within the detection range, the robot arm controller controls the robot arm to set an emitting direction of the laser beam to a direction different from a direction of the person.

Abstract: A three-dimensional measuring device includes a human detection information receiver for receiving information from a human detection sensor that detects a person present within a detection range, a laser emitter for irradiating a region including the object with the laser beam, a laser emission controller for controlling power of the laser beam irradiated from the laser emitter to first power and second power lower than the first power, an image capturing device for imaging the object, on which the laser beam is irradiated, and acquiring image data, and a point-group-data generator for generating, based on the image data, three-dimensional point group data of a region including the object. When the human detection information receiver receives, from the human detection sensor, first information indicating that a person is absent from the detection range, the laser emission controller controls the power of the laser beam to the first power.
