    The objective of the project is to develop a semi-autonomous architecture of a Macron, “Handicap Guidance Support System “ that consists of perceptual and navigational capabilities by means of sensory technology. The wheel car agent aims at improving independent mobility of multi-disabled individuals, and this project focuses on integrating sensory information and human machine interaction. The perceptual navigation system consists of a collection of sensors. The Handicap Guidance Support System base on standard power that consists of two front pivot wheels, two rear motorized wheels, a battery pack, and a controller. The wireless joystick provides the system wireless access up to 60 meters. Front wheel controls the direction using H-Bridge mechanism while rear wheels controls the speed using PWM circuit. The two limit switches prevents it from extreme movements. Collision detection is carried through ultrasonic sensors. For night operations an automated light system is used which turns on itself when the darkness prevails. A Head Operation is also doing operating job of our vehicle to control the front wheels. Our head motion detection system has a advantage that it works only with head tilting not by rotating so the operation will be sensitive as well as accurate.
