Subject follower by using firebird V

Subject follower is one of the most important aspects of autonomous robotics. Subject following is a task which is used for detecting the objects placed in the path of your robot or any vehicle and following that Subject keeping itself at some fixed distance from the Subject. So, to protect the robot from any physical damages and following it. An Subject following robot is an intelligent robot, which can automatically sense and follow the Subject. In this project, we will learn How to design an Subject follower robot with AVR ATmega2560 microcontroller using Sharp IR Sensor. This robot is an automatic robot i.e no manual control is needed. The robot will follow an Subject keeping itself at a fixed range of distance from the Subject. Whenever the Subject stops or there is no Subject in front of the robot, the robot will stop. The above process continues till the robot finds an Subject at some fixed range of distance. Here, we will use one sharp IR sensor to detect Subject and to follow it. We place the sharp IR sensor in the front side of the robot and the sensor will be pointing towards the front of the robot.
