Micromouse 2013-2014 

This is the forth year for me to do Micromouse.

I am having this new design by hollowing the front part of PCB of mouse in order to reduce weight.

Mouse is being assembled and ran same as I expected. I am still in the process of achieving better performance. 

Now it ranks #1 at United States based on performance. I am working on my way to be the top 1 in the world one day :)

I participated 2014 APEC international Micromouse Contest on March 17th, 2014,
at Fort Worth, Taxes,  and took 5th place amount all professional Micromouse
players entries in the world , and the raw best running time scored at 4th place.
