Obstacle detection Robot with Ultrasonic Sensors



Obstacle detection Robot with Ultrasonic Sensors automatically senses the presence of a obstacle in its path and deviates its path or stops its journey. The obstacle detection mechanism is managed by a ultrasonic sensor which makes uses of ultrasonic waves to find the presence of a obstacle in its path.

                        The robot consists of an 8-bit microcontroller to communicate with the sensor and takes any action depending upon the feedback received from the ultrasonic sensor. Here the micro controller part is to control the movement of the robot as well as to read the input from the sensor unit.

This also consists of few dc motors to rotate the wheels of the robot. The motor is rotated as per the direction in which the robot has to be moved, these kind of intelligent decisions are to be taken by the controller.


     The major building blocks of this project are:-

    • Regulated Power Supply
    • Microcontroller based Control Unit
    • Ultrasonic Sensor
    • Geared DC motors
