Sure the mice are cool, but can we talk about the animations at 8:40? So impressive! No idea how they were made, but it really helped understand the concepts. Hats off to the team behind them.
As one of those who missed the podium of the All-Japan Competition this year, I can tell you that the level at which they are competing for the champion is on a completely different level.
one of them mentioned that he changed the optical rotary encoder disc from plastic to paper, making it 0.15g lighter!
It's amazing how such a simple concept as a robotical mouse running in a maze can have so many implications and thought put into it.
Wow, I'm almost 40 and I remember competing in this kind of competition back when I was 15 and studying for my IT GCSE. I remember spending hours tweaking the motor commands to the main 2 wheels to be able to take corners as quickly as possible and very crude attempts at a maze searching algorithm - I think I made some terrible combination of trial and error and "always keep your hand on the left wall". One of my best memories of that class :)
I wish competitions like this were big in the US as an educational circuit with different divisions for middle school, high school, and college. There isn't really the massive hurdle of cost and equipment required next to most other competitive events/sports, but there's room to learn so much about all the different disciplines involved. I've helped teach some basic programming and embedded systems lessons at my old rural high school when a teacher of mine asked me to come in for her class, but she was the last teacher left that would even think about interesting academic adventures for the students. A cool result of those lessons was that she went on to really get into robotics and the next school she went actually allowed a robotics club, and they competed in all kinds of stuff at a national level.
I love these kinds of things. It feels like you met someone 10 years ago and thought their hobby was kinda interesting. Then you come back and they have taken it 1000x further than you could even conceive of 😂😂😂
Those turns are unreal, it looks like the mouse is simply teleporting across across certain parts of the maze
Sometimes you come across a thing you've never heard off, and it opens up a whole world for you.
I never heard of this, but it seems to be a longstanding scene of people exited and engaged in a very specific hobby going on for half a century.
People are awesome.
Im a motorsport enthusiast and got really excited when they announced Roborace. Sadly it never caught on and became a joke before disappearing.
Seeing those robot mices racing in those mazes really is awesome and I'd happily watch an AI race with full size cars and tracks.
Optimization has always been my issue as a programmer. I love the initial phase of learning and growth. Just discovering a problem and new tools to solve said problem is great. I'd say the most improvement you'll ever make is gonna be during the initial stage of problem solving. You'll go from not being able to solve it, to solving it, to minor tweaks that yield big gains, to slightly smaller gains until it tapers off. Then you hit a point where the amount of effort and tedium required for even small breakthroughs starts to be so much it doesn't feel rewarding. It's something I'm aware of, and wish I could change, but I still haven't quite worked out in my motivation.
I think it would be very interesting to re-create mazes from earlier years to compare current mice side-by-side with the times of their great, great grandfather mice, had they run the same maze together.
I was dying imagining how it worked at the start. And then you came with the most freakish didactic and animation that blow my mind. Congratulations, this channel is crazy awesome
It’d be cool to see a maze with different elevations throughout.
This channel has consistently dished out amazing science and tech content for so many years.
This is a phenomenal little doc. Super interesting, and info is presented in a way with essentially zero fluff, which is just so rare these days. Thank you!
I would love to see mazes that allow non-straight walls
As someone who has participated in robotics competitions, it's so emotional, it's like horse racing, but you have spent months building the horse with everything you have. Just being there with all these people, seeing their genius solutions to the problem, it's so much fun. I would truly recommend it to anyone
Wow, how dedicated are these guys.
Amazing how people set goals and fully commit themselves to it.
As an electronic engineer, this is one of the most epic electronic engineering vids I've seen. Thanks Veritasium
The next step will be to turn this into something more difficult like recognising stuff on the path, avoid moving traffic, add wall materials, curves, different path sizes, etc. Very nice to watch and to learn different strategies along the years. Thank you.
