3
Overview

• To build a robotic mouse that is able to maneuver
  its way through a maze using 4 side sensors and
  our ingenious algorithms. Hopefully to not only
  finish the project but to competitively
  challenge, if not win, in the competition.

Sensor Module

• How is the sensor circuit implemented?
• How do the sensors work?
• Why 4 sensors?
• Why side instead of top down?
• How does the A/D converter work?
• What does the Rabbit do?

Move Diagram

• Forward
• Adjust left
• Adjust right
• Turns (90 or 180-degrees)
• Turn right wheel (CW or CCW)
• Turn left wheel (CW or CCW)

12
Wall-hugger

• Mouse will follow the left or right wall of the
  maze
• Not a definite or efficient way to find the
  center
• Main goal is to perfect traction and turning

13
Algorithm (Modified Flood-Fill)
The mouse will use distance values to move about
the maze
The distance values represent how far the mouse
is from the destination cell They are followed
in descending order until the mouse reaches the
center
14
Algorithm (Modified Flood-Fill)
If a cell is not the destination cell, its value
should be one plus the minimum value of its open
neighbors.
Mouse can only go north or south
Value of cell is updated

Yet to be completed

• Assembly of mouse hardware
• Coding(x10)
