Preliminary Design Review EE 296 – Micromouse Spring 2007

Team Giga-Cat Team Members Mark Fujihara Christopher Ho Katherine Ishida David Ota

Overview Build an autonomous robot mouse that can find the center of a 16 x 16 maze and then calculate the shortest path to the center.

Our Design So Far…  Top Down sensors for path/wall detection  4 sensors at each corner  3 for error correction  1 for wall detection  2 sensors in the middle for error correction during turns  Two wheels and a ball bearing for mobility  Stepper motors

So What Have We Done?  These have been our accomplishments up to this point  We have our sensor layout pretty much final.  We have our chassis design pretty much final.  We started buying parts.  We started building the chassis.

What Now?  Finish building the chassis  Wire the rabbit with motors and sensors  Write a code and program processor  Test and Debug EVERYTHING!  Movement  Sensor Placement  Code
