Wireless Inter-Vehicle Communication Among VEX Robots

Abstract

Dramatic advances towards the development of robotic networks occurred in the past few years. The availability of such robotic networks has not only promoted research in coordinated control theories, but also helped to introduce these cutting-edge topics into undergraduate robotic courses and curriculum. This paper describes construction of a VEX robotic network with wireless inter-vehicle communication. Robots, built using the VEX robotic kits, are integrated with XBee modules. Detailed procedures are given, including configuration of the XBee modules, connection of the VEX micro-controller, Cortex, with the XBee module over the UART port, and design of communication protocols for sending and receiving of positions from each other. This VEX robotic network can be easily obtained at other institutions. Educators can integrate multi-robot technology and coordinated control subjects into undergraduate robotics education.
