Obstacle detection and avoidance can be considered as one of the most captivating term in designing robots. This technology provides the robots with senses which it can use to traverse in unfamiliar environments without damaging itself. In this paper an Obstacle Avoiding Robot is designed which can detect obstacles in its path and maneuver around them without making any collision. We can consider it as an autonomous robot when we use it in auto mode and manually it can be controlled via our smartphones as well as, it successfully maneuvered in unknown environments without any collision. The hardware used in this project is widely available and inexpensive which makes the robot easily replicable. This paper introduce us with the outcome that can objectify itself in many scopes. The robot would have the capacity to detect obstacles in its path based on a predetermined threshold distance. After obstacle detection, the robot would change its course to a relatively open path by making autonomous decision. It would require no external control during its operation in auto mode ,it can run under our guidance with the help of manual mode installed in the device. It can measure the distance between itself and the surrounding objects in real-time. It would be able to operate effectively in unknown environment, where human penetration may be fatal. With the growth and evolution of robotic terms our research can be introduced as another venture to generate quality outcomes.
