Robot safety system for connecting peripheral device to a robot controller

Abstract

A robot system allows an operator to connect a peripheral to a robot controller without entering the operation range of a movable robot assembly. The robot controller has a data communication interface therein which is connected through a connector cable to a relay that is mounted on a safety cage. The relay has a connector for connecting a data communication cable to which a transmitter/receiver is connected. A peripheral such as a programmable logic controller or a personal computer is connected to the transmitter/receiver through a data communication cable. When the data communication cable connected to the transmitter/receiver is connected to the relay, the robot controller is connected to a network. The robot controller can easily be connected to the peripheral by connecting the data communication cable to the relay.
