Preliminary Design Review Micromouse EE 296 Spring 2008

Aether Burst

Our Team  Blaise Arita Team Leader  Maran Osakoda Organizer  Shaunty Kleinschmidt Programmer  Matthew Menor Designer

Overview  This semester we will be designing, fabricating, and programming a small robotic mouse to make its way to the center of a difficult 16X16 maze.

Accomplishments So Far Top looking sensors Made a prototype uMouse General Structure of our uMouse Bought most of the materials Started writing some of the Algorithms

A Look into the Hardware  This is what we first started off with:  Material: 1/32 Aluminum  Problems: Very thin, Not rigid Wasted Space No support for other hardware components

Our Ideal uMouse

Our uMouse Now  Material: 1/16 Angled Aluminum 8 Shortened M3 Screw  Lighter  Motors very close together  Use 8 AA batteries  Use Velcro to secure battery holders  Use “mini furniture sliders” to keep the uMouse balanced  Use top 2 Aluminum plates to mount circuit boards

Some Potential Problems  No Wheels  Can’t test height off the ground  Can’t test position and distance of sensor boards  Difficult to keep wires organized  Fitting the circuit boards on the chassis with the wheels  Finding the quickest and simplest way to find the center  Once to the center, how to go back to the start efficiently  Motors getting too hot  Supplying enough power for the 10 minutes  Time Management

Tasks Remaining  Number of sensors to be used  Need to test sensors for approximate wall distance  Build circuit boards  Finish construction of uMouse  Program and test on uMouse
