What is a Micro Mouse

A Micro Mouse is an miniature electro-mechanical robot, typically consisting of three main subsystems:

1. The drive system2. An array of sensors, and3. The control system. Its purpose is to find its

way through ANY type of maze - in the shortest amount of time.

It integrates several different disciplines of engineering, ranging from electrical to mechanical to computer science

Sensors in a Micro mouse A device that measures

or detects a physical condition.

An electronic sensor converts this measurements into an equivalent analog or digital electrical signal.

Detect presence/absence of walls.

To be able to run straight.

To be able to position and

orient itself in the maze.

Microcontroller:

Choose the controller that has sufficient

Amount of FLASH memory to store your program Amount of RAM memory for variables Number of Timers Min of TWO 16 bit timers or ONE 16 bit timer with TWO output compare channels and ONE 8 bit timer Number of ADC channels Good operating speed ATMEGA32 of Amtel made is one that is suitable

STEPPER MOTOR

STEPPER MOTOR is a brushless DC motor whose rotor rotates in discrete angular increments when its stator windings are energized in a programmed manner. Rotation occurs because of magnetic interaction between rotor poles and poles of sequentially energized stator windings. The rotor has no electrical windings, but has salient and/or magnetized poles.

Batteries:Choose batteries that can provide high voltage and high power with low weight

Should have current capacity more than 700 mah

Ni-MH & Ni-Cds Can provides high current at 1.2 V Can be charged by Constant Current or Constant Voltage chargers

Li – Ion Can provide high current at 3.6v Should be charged using CCCV charger .
