Maze Solver Walking Robot

Published on 20 May 2022. Written by Tej Kumar

In our Childhood, we used to solve Mazes in the books and News Papers. It is very interesting right?? Imagine there is a robot which can solve any kind of maze by itself. Through this project you are going to create unique Walking Robot which can solve any kind of maze on its own.

You will need an Arduino Uno board for interfacing microcontroller with IR Sensors and Servo Motors. Here the IR Sensors will act as Eye of the Walking Robot. There are many logics we can use to solve the Maze. Few of them are Left-Left logic, Right-Right logic and Right-Left logic. Of all you are going to use the Left-Left logic. You will program the microcontroller in such a way that whenever the Walking Robot Identifies a T-junction, it should take left turn and follow the LINE. Whenever the robot identifies a turn, it should follow the turn. Whenever there is no line detected by any sensor , the walking robot should stop and it will the reach point, thereby reaching the reach point, the maze has been solved.

Project Description:

Arduino Uno: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
Servo Motors: A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is a signal (either analogue or digital) representing the position
Motor Driver: Generally the Arduino board is not capable of providing required amount of current for running the motors. So we use a device called Motor Driver which will provide sufficient current for driving the motors.
IR Sensors: The component we use to find whether there is any obstacle in the path in which our trolley is going are IR sensors (Infrared).

Project Implementation:

Interface the IR Sensors and Servo Motors with the Arduino board
Power your robot and upload the code
Place your Walking Robot on the Line
The robot will start walking in forward direction till it detects the turns in the line
Based on the programming logic you used, it will take turns
Once the Walking robot doesn’t detects any line, it will stops there and maze has been solved

Software requirements:

Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board

Programming language: Arduino Programming (C++)
