1. Preliminary Design Review Micromouse Team: Ocha

2. Team Members Kanoa Jou Ryan Sato KiWoon Ahn Brett Ikei

3. Overview of the Project  Traditional top down style mouse  Implementing infrared sensors  Implementing stepper motors  Begin with an easy design  Making mice a wall hugger or random turns  Design more complicated algorithm  Mouse can find the quickest way to the center

4. Block Diagram Mouse/Motors Battery Rabbit Sensor

5. Rabbit Module  Inputs from the sensors  Algorithm  Code

6. Inputs from the Sensor  Sensor layout

7. Algorithm  Right wall hugger  Go straight while front sensor is false and right sensor is true  Turn right when right sensor is false  Turn left when right sensor and front sensor is true.

9. Incomplete Tasks  Build  Complete circuit  Mounting of Sensors  Power supply  Combining all components  Code

10. Potential Problems  Power supply not adequate  Hardware  Wheels not aligned  Body not balanced
