The main aim of the project is to design a robot which can detect the obstacle and pothole while moving and alerts the person through buzzer along with RED LED indication. The system uses ultrasonic sensor to detect the obstacles in its path and MEMS sensor is used to detect the potholes. DC motors are used to moves the directions of the robot. The main controlling device of the project is Arduino nano microcontroller. Ultrasonic sensor, MEMS sensor, Buzzer and DC motor along with l293d motor driver are interfaced to the microcontroller. We are placing ultrasonic sensor at front side of the robot. When the robot starts moving it will automatically detect the obstacles in its path using ultrasonic sensor and stop the robot automatically and activate the buzzer along with RED LED indication. When the robot detects the potholes by the mems sensor and process this data to the arduino nano then arduino nano will activate the buzzer for alerts and switch on the GREEN LED. The Arduino Microcontroller is programmed in Embedded C language which intelligently performs the specific task.
