Abstract: In this paper we are mainly focusing on the design of embedded controller for self-driving car in a unique way. Here two major modules plays a vital role, one is detecting the obstacle around the car and another one is tracking the exact location of respective car. we can detect the obstacle with the help of RADAR, Li-DAR or Ultrasonic sensors. By using these sensors for detecting the obstacle it is useful to avoid the accidents and allows to move car smoothly without any intervention with the surrounding vehicles. In our paper we are using ultrasonic sensor to detect the obstacle, once it will find the obstacle immediately it slowdowns the speed of the car based on that we have developed the module. Once the speed of the car will reduce, ultrasonic sensor scans surroundings of the obstacle with an effectual angle of 30°of both left and right side of an obstacle, it also finds the obstacle free zone. Once the obstacle free zone have been founded, car move towards free path. If free zone is not found sensors keep on sensing the obstacle till the free zone is found and also status of the car will be notified to the micro-controller.The micro-controller immediately send commands or information to the passenger in the form of audio signals. In the second module we have focused on tracking the car with the help of GPS NEO-6 module. It helps to track the car based on the accurate co-ordinates of longitude and latitude of the respective global position. So this module will helps to navigate from source and to reach the destination without any intervention of surrounding vehicles.
