MAZE SOLVING ROBOT (MICRO-MOUSE)

OUTLINE

BackgroundSystem RequirementsDesign ChallengesSystem OverviewHardware and Software Q/A

BACKGROUND

Micro mouse competitions began in the late 1970s. In this event, a 16x16 maze is used and solved by small robot mice. These competitions are held worldwide and most popular in UK, U.S., Japan, Singapore, India and South Korea.

The current world records are around 4 seconds and are held by

Ng BengKiat.

MOTIVATION

Building a Smart Machine that can find its way out of any maze.

MAIN OBJECTIVE

The aim of this project is to design a robot that is capable of leading itself to solve a maze using the wall follower algorithm.

SYSTEM REQUIREMENTS

Being able to detect obstacles for short distances depending on the width of the path in the maze.

Move according to the algorithm its programmed with.

Saving that was taken into a stack.

Cost should be within the budget

DESIGN CHALLENGES

Sensors Ranges.

Size of Maze.

Accuracy of Robots turns.

Controlling simple DC Motors is really Hard.
