Autonomous Maze Solving Robot

Abstract

In this article, the construction and programming of a line-follower maze solving robot will be presented. In the beginning a general overview is offered, followed by the main technical aspects and implementation details. The main objective of the robot is exploration and terrain mapping. However, after finishing the exploration process, it is often desired that the robot must be able to find a specific object or return to a given point. The proposed terrain is a maze consisting of lines, turns and crossroads, which the robot detects using infrared sensors. An algorithm for exploring, learning and solving the maze has been implemented. Therefore, the robot manages to optimally find the exit of the maze during the second run. A Bluetooth module was used in order to broadcast real-time data and plot it in Matlab during the robot's operation.
