Micromouse 2011-2012

This is the second year that I work on Micromouse, since I wasn't satisfy with the
performance of the mouse from previous year, I did huge amount of research and
made a brand-new, extremely competitive world class Micromouse. I put lots of
efforts on doing research on STM32 and how to make a perfect motor mount in
order to make this tiny 4-wheeled robot gets perfect balanced.

2nd one from left was the the lastest update for my STM32 micromouse

 

 

It's completely constructed after I received all replacement parts
