2016 All Japan Micromouse Contest – full entry details

When entering for the All Japan Micromouse contest, you have to enter a whole bunch of details about your mouse – number of wheels, types of motor, motor driver, sensor devices, gyro, CAD software. It goes on and on. I always wondered what happened to that information. This year it has been published along with all the run times and other mouse details. Tricky if Japanese is not your first language but I am sure you will figure it all out:

Maze File Archive

Over the years, I have collected a good number of micromouse mazes. Some of these are from previous contests, some are just odd test mazes.
