Control of Mobile Robot Using Visual Feedback and Wireless Communication

Abstract

A camera based wireless control of a mobile robot is designed & implemented in this paper which is suitable for indoor application. This system consists of a mobile robot (Fire Bird Nex Robot), Laptop as controller, camera as sensor and XBee (zigbee) for wireless communication. A Wireless camera is used to capture images of the environment in which mobile robot is located. Laptop (Matlab) process images and calculate current position & orientation of robot using color detection algorithm. Control signals are sent to robot via XBee modules to drive it to desired location. This whole system is realized & experimented in a lab environment. Experimental results are presented to move robot between two locations.
