Project OverviewTo create, a small autonomous robotic mouse that will:1. Navigate it’s way safely to a central point of a maze2. Map the maze 3. Find the shortest route from the start point to central point

of the maze.Contest rules must be followed.

Learning Expectations Implement new technology into to the components

Understand how to inter-connect each component and

improve their functionality within circuit.

Learn how to work efficiently as a team in an engineering

work environment.

Improve on previous autonomous robots

Discussion of ApproachExplore new components

1. Pic Microcontroller vs. Rabbit Microprocessor2. Side Sensors vs. Top-down Sensors3. Smaller Stepper motors4. No Voltage Regulator5. Wheels6. PCB board

Design Micromouse1. Schematic layout2. PCB 3. Physical Layout4. Software

Build1. Transform schematic design to PCB2. Construct chassis3. Program

Test / Debugging1. Does everything work?2. Does the mouse do what we want it to do?

Potential Problems Finding the right components
