3. Overview To build a robotic mouse that is able to maneuver it’s 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.

4. 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?

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) Mouse can only go north or southValue of cell is updated If a cell is not the destination cell, its value should be one plus the minimum value of its open neighbors.
