An article conveying system includes a tray that is disposed on a floor surface and on which an article to be conveyed is mounted, a robot provided with a force sensor that detects an external force, a frictional force reduction device provided in at least one of the floor surface or the tray, to adjust a frictional force between the floor surface and the tray, and a controller that controls the robot to apply a lateral load to the tray and thereby slide the tray on the floor surface, and controls the frictional force reduction device based on a magnitude of the external force in a direction of the lateral load that is detected by the force sensor when the lateral load is applied.

Article conveying system

A robot system comprises a robot provided with a robot arm and a robot hand, and a control device for controlling the motion of the robot, wherein a permitted area where a teaching operation for the robot hand should be permitted is preset within a maximum area which the robot hand can reach. The control device is provided with a judging part which judges if the robot hand as a whole is present in the permitted area, based on robot hand position information, and a teaching operation restricting part which permits a teaching operation for the robot hand when it is judged that the robot hand as a whole is present in the permitted area and prohibits a teaching operation for the robot hand when it is judged that the robot hand as a whole is not present in the permitted area.

Robot system for preventing accidental dropping of conveyed objects

A device which prevents a gear from ending up being damaged while enabling the gear to be more easily and suitably gripped is provided. A gear gripping devicecomprises a pawl which is provided to be able to move so as to approach a circumference of a gear G and which can engage with a gear groove which is formed at the circumference of the gear, a first drive partwhich drives the pawl to abut against the circumference of the gear G, a second drive partwhich makes the gear G rotate in the circumferential direction of the gear G, and an engagement detection partwhich detects if the pawl has engaged with the gear groove.
