The image display apparatus includes a light attenuation section that reflects a portion of light emitted from a light source and a scanning section that scans the light reflected by the light attenuation section. The light attenuation section transmits a portion of light emitted from the light source. The light attenuation section has reflectance and transmittance and the reflectance is smaller than the transmittance. The image display apparatus further includes a light receiving element on which the light transmitted through the light attenuation section is incident. The image display apparatus also includes a control section that controls activation of the light source in accordance with detection results of the light receiving element.

A three-dimensional measuring device is a three-dimensional measuring device that performs three-dimensional measurement of an object using a laser beam. The three-dimensional measuring device includes a laser emitter disposed in a movable section of a robot and configured to irradiate a region including the object with the laser beam, a laser emission controller configured to control driving of the laser emitter, an image capturing device configured to image the object, on which the laser beam is irradiated, and acquire image data, and a point cloud generator configured to generate, based on the image data, three-dimensional point cloud of the region including the object. The laser emitter includes a laser beam source and a diffuser configured to diffuse the laser beam emitted from the laser beam source.

Three-dimensional measuring device, controller, and robot system

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.

Robot controller and robot system

At least one of a first beam portion and second beam portions is provided with an out-of-plane vibration suppressing structure configured to suppress vibration of a movable portion in an out-of-plane direction vertical to an in-plane direction. Thus, unintentional occurrence of unintentional movement in the out-of-plane direction vertical to the in-plane direction can be suppressed. Furthermore, in this case, a size reduction of a device can be achieved in comparison with a case where a device includes a motor disposed for rotation driving, for example.

A robot system includes an automatic transport device, a robot arm that is installed on the automatic transport device, an object recognition sensor that is disposed on the robot arm, an environment recognition sensor, a placement portion that is disposed on the automatic transport device, and a controller, and in which the controller controls the automatic transport device for moving toward a work stand based on a recognition result of the environment recognition sensor and controls the robot arm for transferring a plurality of component kits from the placement portion to the work stand based on a recognition result of the object recognition sensor after controlling the robot arm for taking out the components from a component storage unit based on the recognition result of the object recognition sensor and creating the plurality of component kits on the placement portion.

Robot system

Movement of a movable portion without stopping at any moment can be achieved by a simple configuration including a beam structural portion including two beam portions extending in directions different from each other and one driving portion. Furthermore, a size reduction of a device is achieved in comparison with a case where a device includes a motor disposed for rotation driving.

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.
