An Arduino micro controller based robot which first analyzes the maze in the dry run by following lines through IR sensors and then calculates the shortest path from the source to the destination.In this paper we have discussed a unique general algorithm for exploring and solving any kind of line maze with another simple one for simple mazes without loops or with loops having highest two branches none of which are inward. For the general algorithm, we need a method to map the whole maze, which is required if the maze is complex. The proposed maze mapping system is based on coordinate system and after mapping the . In order to find the coordinates of the turning points and junctions, linear distances between the points are needed, for which wheel encoder was used. However, due to non-linear movement of robot, the directly measured distance from the encoder has some error and to remove this error an idea is built up which ended by deriving equations that give us almost exact linear distance between two points from the reading of wheel encoder of the robot moving in a non-linear path
The game field consists of an arena having dimensions 2310 mm X 1980 mm (lxb).It consists of the following: 1.The arena is composed of random paths made up of white strips. 2.Angle between two adjacent white lines in the path is either 90 deg or 135 deg. 3.The width of all white stripes will be 30mm. 4.The actual arena at the competitionwill consist of slight alterations in the path.
