Robot proprosal

The purpose

To build a mapping robot that goes through a maze and maps it out.

Function, Structure and design

The robot will move by a chassis with four wheels. The robot chassis will be powered by its on dc power supply. The robot movement will be controlled by the arduino. The arduino micro controller will powered by a 9v battery adapter. The arduino will tell the chassis where to move by the result of the proximity sensor measurements. The robot will be using two (or one rotating) proximity sensors. One will be place on the right side of the chassis to detect if a wall on its right side and the other in the front to detect if a wall is in front of it.  The proximity sensors will keep the robot a certain distance from the walls. As the robot move, it will keep an equal distance from the side of the walls. When the robot detects a wall in front of it, it will make a right turn.  As it moves through the maze, it will record its movement. It will know that it is out of the maze once it detects a black (color may change) line. Once it completes the maze, it will display a simple view of the routes in the maze on a LCD.
