This document describes the development of redundant communication methods for robots used in nuclear applications. It aims to minimize wiring by serializing communication lines between a master control system and sub-modules like analog front ends and actuators. It implements three redundant communication methods - RS-485, optical fiber communication, and power line communication - to ensure uninterrupted data transfer even if one method fails. The methods are tested by transmitting joystick data between two microcontrollers to control a robotic arm model over each communication channel individually and combined. Results found the system works efficiently over any single channel and provides redundancy by using multiple channels.
