Abstract
It is an anti-accident car which automatically turns from its original path when any hurdle comes in front. The sharp UV sensor mounted at the front side of the robotic car for this purpose. The sharp UV sensor is used to detect the obstacles. While moving forward if sensor does not detect any hurdle the Robotic car is going to its normal speed. If sensor any of the three detects any hurdle, then the Robotic car slows down and takes the decision to make a smooth turn left or right with the help of other two sensors. The back motor (dc-motor) speed is controlled by sensor’s output while front motor is bidirectional motor and controlled by H-bridge. Sensor output is controlled by PIC16F877A microcontroller. The PIC Controller will be used to perform PID Algorithm control the speed of motor, while PIC16F676 will be used for the movement of the front wheel supported by servo motor. PID Controller has superior performance as compared to conventional controllers. The advantage of using PID closed loop control system is the gain can be controlled in closed loop system. PID algorithms monitor and adjust the gain of robot based on the characteristics, of the feedback to improve robot performance .Whole PIC programming is done in C language.
