The purpose of this project is to build a solar powered vehicle/car with Ultrasonic Sensors. This Vehicle/car automatically senses the presence of obstacles in its path and changes its direction of movement. The obstacle detection mechanism is done by an ultrasonic sensor that makes uses of ultrasonic waves to find the presence of an obstacle in its path.   The proposed project is a Microcontroller based control system, solar powered DC motors and Ultrasonic Sensor. This autonomous vehicle/car senses the obstacles in its path by continuously transmitting the ultrasonic waves. If any obstacle comes in its vicinity then the ultrasonic waves get reflected back to the vehicle/car. The ultrasonic receiver fitted on the vehicle/car senses these ultrasonic waves and this information is passed onto the Microcontroller. Now the Microcontroller takes necessary action like taking the diversion, reversing the vehicle/car direction etc. The power required for the operation of vehicle motors is supplied from solar panels connected to a battery. Also, the voltage from solar panels will be displayed on LCD by interfacing solar panel to Microcontroller through a voltage measuring circuitry. The Microcontroller is programmed using Embedded ‘C’ language.   This vehicle/car is designed in such a way that there is no requirement of manual attention towards it. It makes use of the ultrasonic sensors to detect the obstacle present in its expected trajectory and dynamically changes the trajectory to be followed.
