New TETRA micromouse is blazingly fast. How does it do it? (Video)

micromouse 2009-14

The basic rules and regulations for the Japan Micromouse contest haven’t changed in 30 years. You might think that would stifle innovation and creativity, but exactly the opposite has occurred. Competitors continue, year after year, to introduce surprisingly new and fast designs. This year one new design, TETRA by Kato-san, really stood out dramatically, and clocked unbelievablely fast times.

We asked David Otten, a 22 year veteran of the competitions, to share his observations, and the current theories on how Kato’s robot was able to achieve world-class performance.

    Fun content, but the music bed is WAY too loud. But thanks for the video!

  2. It looks so simple, but the results are amazing! When you are talking about pushing the boundaries that far I think it will be years before it is optimized.

  3. it would be fun to calculate what the theoretically fastest time is given known friction of tires for braking and peak motor speeds and optimal trajectory. seems like it cant be much faster than kato’s 4.7 sec

  4. What is the material used below the PCB instead of castor wheels?
