Abstract: A machine learning device included in a radio repeater selection apparatus has: a state monitoring unit that monitors, as state variables representing multiplexed communication path data specifying a construction state of a multiplexed communication paths and multiplexed radio communication state data specifying a state of multiplexed radio communication among devices to be managed; a determination data acquisition unit that acquires determination data designating a result of determination on whether or not the construction state of the multiplexed communication paths is appropriate; and a learning unit that learns the construction state of the multiplexed communication paths and the multiplexed radio communication state data in association with each other on the basis of the state variables and the determination data.

Abstract: A robot system and a robot controller, by which a teaching operation, etc., of a robot can be intuitively carried out by a simple operation. The robot has a sensor arranged on a surface of a movable part or the robot, and the sensor is configured to detect a three-dimensional position of an article, when the article contacts or is close to the sensor. When the article reaches a reference position, a mode change section switches a motion mode of the robot to a following mode. In the following mode, based on the direction of movement of the article from the reference position, the direction of motion of the robot is determined. Then, a motion control section controls the motion of each axis of the robot so that a portion where the article contacts moves in a direction generally the same as the direction of movement of the article.

Abstract: A portable operation panel having a vibration motor configured to tactually provide information to an operator, and having a configuration capable of rapidly and accurately detecting a structural damage or deterioration of the vibration motor. The operation panel has a controlling section configured to control the behavior of the operation panel; a vibration generating unit capable of vibrating at a natural frequency of the operation panel; a vibration detecting unit configured to detect the vibration and/or acceleration of the operation panel; and an inputting section to which the operator can input information. The controlling section judges that the operation panel has an abnormality, when a vibrational amplitude of the operation panel detected by the vibration detecting unit, during the vibration generating unit vibrates at the natural frequency, falls below a predetermined threshold.

Abstract: A controller, a wireless module and a wireless repeater, by which a possibility of interruption of wireless communication between the controller and a wireless operation panel can be significantly reduced. The wireless system includes a robot and a controller for controlling the robot. When the robot is to be taught, a human uses a wireless teaching pendant so as to teach the robot. The controller has a wireless module for wirelessly communicating with the teaching pendant, and the wireless module is configured to receive a signal from the teaching pendant via at least one wireless repeater, as well as a signal directly transmitted from the teaching pendant. In other words, the wireless module receives a multiplexed signal generated by multiplexing signals from the teaching pendant by using at least one wireless repeater.
