Half-Sized Micromouse
Half Sized micromouse is a new catagory other than classic full size micromouse.
The length and width for cell is half size of a full size maze, however, the total size for the maze remains the same, which means instead of 16x16 cells for classic micromouse, a half sized micromouse maze will be have 32x32 cells. This is much harder to build the robot in a smaller size besides the search process takes much longer time.
It's also extremely hard to put all components into such a small PCB
It's finally assembled and be able to run in a full size maze(since I don't have have half size maze yet)
I believe this is the first working half size micromouse ever in United States

A video that the mouse running in a classic size maze(since I don't have half-size maze for now)
================== design stage ===================
determine the specs
Tried to print about demo parts for motor/encoder mount with makerbot for demo purpose
