Routing of Autonomous Wheeled Mobile Robot in External Environment using Wireless Sensor Network

Abstract

This paper proposes the application of wireless sensor network for routing of wheeled mobile robots in dynamic external environment. Wireless sensor network (WSN) in navigation of mobile robots avoids the need of knowledge of map in advance. Sensor nodes will enable mobile robot to build the map of the external location while moving around. The problem of localization can be solved by determining robot’s physical distance from sensor nodes. In proposed navigation system, the robot can navigate autonomously without the need for a map, by acquiring the information from RF emission sensors deployed in an external environment. This approach is easy to implement and proposed model shows that accurate navigation can be achieved by this method.
