Proposal Presentation
Members
 Toy Lim – Project Manager
 Kyle Montpas – Software Leader
 Tyson Kikugawa – Hardware Leader
Overview
 Design and build an autonomous robotic mouse
to find its way to the center of a maze as fast as
possible
Hardware
 Opted for $250 budget over kit
 Design to be compact and light
 Li-Ion batteries
 Smaller stepper motor – 25.4mm x 38mm sq.
(versus kit – 39mm x 42.3mm sq.)
 Sensors – undecided
Hardware
 PCBs/Circuits
 Incorporate battery charging circuit
 Voltage converters (3.7 V -> 5 V)
 USB Interface for charging and
programming communication
 Structure
 Possibly use sheet aluminum
Software
 Develop sequentially



Drive (forward/backward)
Tracking (drive straight)
Turning (90, 180, 45 deg)
Exploration of maze
Shortest path algorithms
Expected Problems
 Time!
 Developing/Fabrication of

structure
Programming/Debugging
USB Charging too slow?
Motor torque
Sensors – use and
implementation
Expect to Learn…
 Designing a system from scratch
 Using sensors
 Working with bi-polar motors
 Developing navigation software
 Serial over USB emulation
Deliverable Goals
 Have a working mouse
 Be able to find the center of the maze
 Compete in Mini-Competition – Mar. 31
