Line follower Robot is made by using micro controller "msp-430".Using this micro controller,i get the sensors available from the internet.It works as a Robot following a particular line. As the frequency of the color is set up by using the coding procedure and coding of micro controller is done by Energia software(Texas Instruments).This type of robots are used in the Racing games,Battles for children(entertainment),If we connect a Temperature sensor over it too..It tells us how moderate the temperature is ! This is a good device and using different-different components,we can use it for various purposes.If we want to run this device using IR remotes sensors can be attached to the micro controller to operate as simple as possible or as variable as possible.
