In the modern era, the vehicles are focused to be automated to give human driver relaxed driving. In the field of automobile various aspect has been considered which makes vehicle automated. In this paper, considering the different features and the cost, on a small scale a three-wheel vehicular robotic prototype has been designed that will follow the lane and avoid obstacles. Autonomous cars are a developing technology which may prove to be the next big evolution in personal transportation. This report begins by describing the landscape and key players in the self-driving car market. Current capabilities, as well as limitation and opportunities of key enabling technologies, are reviewed, along with a discussion on the impact of such advances on society and the environment.
