M2M communication system for networked robots with low memory footprint

Abstract

A team of robots performing a common task must be able to exchange information about the environment and the progress of task to be performed. For the robots having limited power supply, small storage space, small processing power and very limited range of wireless communication, disconnection with the rest of the network is often a problem if they travel farther from the communication range of any nearest member of the network. To solve this problem, a communication architecture which uses RRT algorithm for searching the lost members of the network has been proposed in order to the route the information from a lost source robot to a destination robot. Selection of a robot for routing in the network is based on its load which is estimated by factors like ongoing processes, battery power, its connectivity, and storage space. We also propose the effective role of the idle robots in the network to increase the efficiency of the communication system.
