Abstract: An encoder includes a first disc and a second disc, a first detector, a second detector, a rotation count detector, and a sender. The first disc and the second disc are mounted on a rotation shaft of a motor. The first detector is configured to detect a rotation position of the first disc within one rotation of the first disc. The second detector is configured to detect that the second disc has made one rotation. The rotation count detector is configured to count a rotation count of the second disc based on an output from the second detector. The sender is configured to send sending data including the rotation position and the rotation count.

Abstract: An encoder includes a rotation position sensor, a first addition information generator, an identification information generator, and a sender. The rotation position detector is configured to detect a rotation position within one rotation of a rotation shaft of a motor. The first addition information generator is configured to generate first addition information for a period at least longer than a data sending period. The identification information generator is configured to generate identification information by which at least the first addition information is identifiable as information to be sent. The sender is configured to send, for the data sending period, sending data including the rotation position within one rotation. The sending data includes first sending data including the rotation position within one rotation, the identification information, and the first addition information.

Abstract: A robot system (1) according to the present disclosure includes: a robot (10#n); a controller (20#n) connected to the robot (10#n) via a wired line to control the robot (10#n); a first wireless device (30#n) connected to the controller (20#n) via a wired line; and a teaching device (50) configured to be capable of communicating with the first wireless device (30#n), capable of being grasped and operated by an operator (2), and controlling the robot (10#n) via the controller (20#n) in accordance with operation of the operator (2), in which a distance (D1) between a position where each robot (10#n) is arranged and a position where each controller (20#n) is arranged is longer than a distance (D2) between the position where each robot (10#n) is arranged and a position where each first wireless device (30#n) is arranged.
