• Software
• Arthur Phanphengdy
• Jackson Ng
• Hardware
• Quincy Quach
• Kang Lu

OVERVIEW OF THE PROJECT

• Make a micromouse that is able to find the center
  of a maze on its own
• Use side sensors
• Go to regionals and WIN!!!

4
Last Year (EE296)

• Used only 3 Top-Down Sensors
• Right wall hugger
• No mapping or solving code
• Just let it run in the maze
• Been able to move 30 cells w/o crashing
• Self-aligning Mouse
• Implemented different speeds (3 gears)
• VERY SIMPLE MOUSE

GENERAL DISCUSSION OF APPROACH (HARDWARE)

• Re-design and build the mouse itself . (Chassis,
  wheels, motor, sensors, etc.)
• Use Copper Boards and Etchant
• Develop CIRCAD skills
• Simplify Circuit Design
• Reduce Soldering Time
• Minimize Size of Mouse

8
General Discussion of Approach (Software)

• Get Analog Sensors working with A/D Converter and
  rabbit.
• Implement algorithm for finding center, mapping,
  and solving
• Find shortest path to center
• Develop proper alignment program
• Include S-turns and 45s

9
POTENTIAL PROBLEMS (Hardware)

• Need to learn how to use CIRCAD
• Errors on circuit design
• Difficulty in precise measurements on side sensor
  placements and chassis design
• Etchant problems
• Limited supplies
• Press-n-Peel, Etchant Solution, PCBs

10
POTENTIAL PROBLEMS (Software)

• Implementing algorithm for finding center,
  mapping, and solving
• Not be able to figure out the right C coding
• Using Arrays
• Debugging code
• Robustness
• Not have enough time to finish

11
WHAT WE EXPECT TO LEARN

• Build upon skills ascertained in 296
• Engineering process of solving problems
• Concepts taught apply in real-life problems
• Develop teamwork skills.
• Develop time management skill
• Develop troubleshooting skills

12
DELIVERABLE GOALS

• Make a micromouse that
• Small and Fast
• Find center
• Map and Flood entire maze
• Solve for the shortest path
• S-turns and 45s
• Go regionals
