OBSTACLE AVOIDING ROBOT DESIGNING USING AVR PROGRAMMING

Abstract

The obstacle avoiding robots are a great boon to the society because of their versatility, and easy maneuvering capability.  These are advanced robots which have the capability to detect obstacles through sensors and move without colliding. The objective of the project to  make mobile robots as the target application and problems that will be covered include : how to make (teams of) wheeled ground robots avoid collisions while reaching target locations, by using the AVR programmed microcontroller. This paper treats the navigation problem of mobile robots to avoid obstacles according to vision information. In present method, first detection of obstacles which exist in front of a mobile is done by robot by calculating the optical flow. Then, based on the area of detection, the optimal trajectory for a robot is decided. The sensor data for supporting a vision system has been used. In order to find the optimal trajectory, the distance between a mobile robot and obstacle evaluating a function is calculated. The microcontroller on the board  programmed with AVR can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators.
