  1. cup o stuff says:

    Those turns are unreal, it looks like the mouse is simply teleporting across across certain parts of the maze

  2. Blender Guru says:

    Sure the mice are impressive, but the animations at 8:40 are surprisingly sophisticated! It made understanding these concepts so much easier. Hats off to the team behind them.

  3. Michael Polakowski says:

    It’d be interesting to add some curved sections to the maze and see how that affects the routing algorithms. It looks like the mice can already handle them mechanically.

  4. Neuro says:

    Once you understand what goes into mouse navigation, this goes from appearing as odd nerd behavior to something genuinely impressive.

  5. Mace Dindu says:

    Absolutely fascinating. It’s a real shame this stuff isn’t aired on major outlets.

  6. M.J. Nilsson says:

    I would love to see a layered maze with multiple floors and ramps, like a parking hall. Bottom is the start and top is the goal

    • Argy Em says:

      And they need to make the problem more complicated again – like adding in the free-standing walls. How about some curved walls, or pegboard holes in the floor, or rough surfaces, or transparent walls, or curtained-off short-cuts?

    • Think About It says:

      Or add “cats” that block parts of the maze as they follow predefined paths. So the mouse has to probe the movement of the cats as well as the walls to find the best path.

    • Shayon says:

      Opening and closing gates like in fall guys

    • Wasgeht Siedasan says:

      Add a lava moat filled with fire alligators

  7. Mr. Wilkinson says:

    It’d be cool to see a maze with different elevations throughout.

  8. Chris Wong says:

    I love how the video is building up the tension of the Japan competition of Utsunomiya trying to beat first place.
    It’s just such a treat to watch

  9. Ryan Salm says:

    This videos was absolutely stunning. You took a sport nobody knew about and turned it into an amazing video. I also wouldn’t of understood a thing without those visuals. Hats off to the team.

  10. Tai Jarman says:

    I did this as part of my electronics university course and it was a lot of fun! Didn’t end up with anything groundbreaking, but it’s great to go through every stage of design and prototyping and create something that actually solves a practical problem, even if it’s a small one.
