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.
