OBSTACLE AVOIDING ROBOT CAR BY USING GSM MODEM TO GET ALERT MESSAGE

Abstract: Obstacle avoidance is one of the most important aspects of mobile robotics. Now day’s many industries are using robots due to their high level of performance and reliability and which is a great help for human beings. This project proposes robotic vehicle that has an intelligence built in it such that it directs itself whenever an obstacle comes in its path. so, to protect the robot from physical damages. This can be design to build an obstacle avoidance robotic vehicle using ultrasonic sensors for its movement. A micro - controller (AT mega 328P) is used to achieve the desired operation. An ultrasonic sensor is used to detect any obstacle ahead of it and sends a command to the micro- controller. Depending on the input signal received, the micro-controller red erects the robot to move in an alternate direction by actuating the motors which are interfaced to it through a motor driver. The GSM module we here going to use is Sim900 which is capable of connecting to GPRS and through which we can send and receive commands.
