3 Overview of Project Our Micromouse Project involves designing a mouse beyond the standard top-down, MOSFET driven setup. We are using smaller motors with motor driver ICs, side sensors w/ Analog to Digital conversion and a flood-fill algorithm to solve the maze.

4 Detailed Overview We are using unipolar motors to move our mouse vs. bipolar motors. We are using side sensors to sense our way through the maze vs. top- down sensors.

5 Detailed Overview We will be using a flood-fill algorithm to solve the maze. This algorithm is distance based, with the mouse keeping track of the shortest way to the center of the maze.

7 Motor Driver Design Description Our Motor Driver circuit consists of one UCN5804B IC chip for each motor. The accompanying hardware is simply 4 diodes and 3 pull-up resistors for the Rabbit inputs. We chose this chip because it was the lowest priced driver that we could find.

8 Motor Driver Design Description This was our test setup. We used LEDs in place of the motor to see how the chip pulses the stepper motor. We also had to verify that the circuit would work at around the 3.15V our motors are rated for.

9 Items Remaining to Be Done Finish PCB Etching Design Etch Board Solder Components Debug Circuits Write and Test Code Debug Code

10 Potential Problems Frying more parts Motors might not provide enough torque. Running out of time Design flaws Troubleshooting

11 Updated Schedule

12 Questions? Meaning of life? Which came first the chicken or the egg? What is the sound of one hand clapping?
