An autonomous robot is a robot that is capable of moving on its own in an unknown and unstructured environment. An autonomous robot is equipped with software intelligence to sense its environment, detect obstacles in its path and move around an unknown environment overcoming the obstacles. There are many robotic designs that are employed in designing of autonomous robots. These designs are usually developed considering the physical environment in which the robot has to be deployed. There are autonomous robots like snake robots, walking robots, autonomous drones and autonomous robotic cars or rovers.
In this tutorial, an autonomous robotic car is designed. The robotic car uses an ultrasonic sensor to sense its environment and detect obstacles. The robot can rotate the ultrasonic sensor from 0 degree to 180 degrees with the help of a servo motor and find an escape route by measuring distance on its left and right side. The robot automatically turns left or right depending upon the side at which there is no obstacle or a path obstruction is at a greater distance. The robot is designed to move around an obstacle detected in front of it. The robotic car designed in this project runs on two geared DC motors and is powered by the battery.
The control circuitry of the robot is built on Arduino UNO. The ultrasonic sensor, servo motor and motor driver IC coupled with two geared DC motors are interfaced with the Arduino board. The Arduino sketch initializes the robot to move in forward direction and manages to detect any obstacle in front of the robot, rotate ultrasonic sensor with help of servo motors, measure distance on left side and right side and turn robot either left or right where ever there is more distance available to move around. The Arduino sketch has been written and compiled using Arduino IDE. The control circuitry is assembled and mounted on a two-wheel and a castor robot.
