, SECTION 1 : PROJECT INTRODUCTION
1.1 Introduction :
For students from BEng / MEng Electronic Engineering level 2, the design,
development and testing of a micro-control-based embedded device through the use of a
handheld, compact robot call Micromouse will take place in typical groups of four
students. Students are expected to compete at the end of the course with their
Micromouse robot. Mouse will win the award with the fastest time to go downtown.
This document provides a report on the development, construction and testing of a
smart mobile robot created to compete in a competition for 'Micromouse.' I planned, built
and programmed the robot Micromouse over the two term periods of this academic year.
This paper will describe all the problems I encountered in the design and development of
this robot, the solutions I have found and the reasons I have to select those solutions.
what is Micromouse?
“Micromouse is an occurrence that solves a labyrinth by tiny robot mice. The
labyrinth is composed of an 18-by-18 cell grid with 5 cm walls each 1.2 cm thick.
The mices are completely autonomous robots which need to be able to enter the
central area of the maze with no help from a predetermined starting location. The mouse
will have to track its location, explore the walls, map out the labyrinth and detect when
the target has been achieved. Once you have found the optimal path, the mouse will
start the path as soon as possible..”
