    Autonomous Robotic Car
    (UMT Lahore, 2012) Muhammad Adeel Kamran; Muhammad Saqib Mukhtar; Asif Abbas
    It is an anti-accident car which automatically deviates its path when any hurdle comes in front. The sharp IR distance sensor and camera is mounted at the front of the robotic car for this purpose. The sharp IR sensor is used to detect the obstacles while the camera is used to avoid that obstacle. While moving forward, if the IR sensor does not detect any hurdle, the robotic car is going to its normal speed. If the IR sensor detects any hurdle, then the robotic car slows down and takes the decision to overtake that hurdle by camera. The back motor speed is controlled by PWM that depends on the IR sensor’s output, while the front motor is a bidirectional motor and controlled by H-bridge that depends on camera image processing data. Both sensor and camera output is controlled by PIC16F877A microcontroller. ADC is used for sensor output, and level converter (MAX232) is used for PC to PIC interfacing. Whole PIC programming is done in PROTON Basic language, while image processing is done in MATLAB.
