The numbers of road accidents are increasing worldwide day by day and most of them are due to human errors including rash driving, carelessness and mishandling. Also the traffic is a big problem in the world. This problem can only be handled by driver less car. The motive is to develop a robo-car that drives without a driver on lanes. It should follow the lane lines on particular track and turn according to the lane. It should contain feature to turn left and right and must take U-turn after detecting end of lane. This can be done by constructing a set of hardware that enables image processing. Algorithms are applied on the fly i.e. image processing is done on real time data. The pollution caused by traffic is enormous and environment is affected adversely. The pollutants release by cars is very minute. The traffic and pollution affect us badly and waste our time and it is very inconvenient. Thus we need an cheap and convenient alternative in order to decrease this risk.
