2017 All Japan classic micromouse contest 1st prize-赤い彗星(red comet) by Utsunomiya san

Best run time = 7.284s

[@ChrisTheCringe]

3:13 this part looks so unreal. You usually see this stuff in cartoons

[@reeddicenso951]

If you think that is crazy, take a look at the 1st place run from 2016: kzbin.info/www/bejne/f5_Klp-Bn9KYmck

[@anteconfig5391]

I just watched that speed run in slow motion, 0.25x normal speed, and I gotta say I love that way that thing corners and course corrects 3:13. It's just awesome.

[@suhu9379]

Yes, that is also one of the reason why we love this game. Mouse with suction fan is the current trend for high speed running micromouse.

[@ATLTraveler]

Peter's car actually took a better route I think, his was just slightly slower.

[@sn4fuls]

Utsunomiya san's car probably took velocity into consideration and therefore took the longer route with less turns

[@ATLTraveler]

@@sn4fuls yes which is probably why he won!!

[@sn4fuls]

@@ATLTraveler and therefore Peter's car didn't take the better route.

[@benlex5672]

Not quite Peter's car is the only one that took that rout in the whole competition On the other side, the computer only computes the time that the car will spend the least, meaning that even though Peter's car might be more fuel efficient if we put it as a real car, it won't be faster on that rout It's like driving on a longer freeway or a shorter county road.

[@lhl2500]

Shortest route and fastest route are rarely the same thing on a course with multiple paths.

[@Zbychu93]

Woah ! I have seen the 2nd place video and that to me was fast. Now this is super fast, only if he chose a different route.

[@error.418]

The route is correct. You can get more speed on long straightaways, so it takes that into account. The shortest path isn't always the fastest since changing direction takes time.

[@patrick7932003]

He took the path with fewer turns. For me, that’s a genius move.

[@Saul30119]

[@lafeo0077]

What does he do to the robot after it finishes a round. He rubs it on something or applies? And why does he do it?

[@3drocket]

Looks like he uses a lint remover to take any dust or hair off the tires. This would be important before the speed run.

[@anteconfig5391]

I thought they were trying to make the wheels extra sticky but +Matthew Simmonds could be right

[@user-ov8ct5bc7h]

Было бы здорово если пустили бы сразу двух мышек и они должны бы были приехать в этот квадрат

[@HiAdrian]

Wicked!

[@neon1300]

I am curious what algorithm they were using. It looks like the car was trying to turn right whenever possible (dfs), but it also skipped some right turns and went straight instead in some situations.

[@JuneJulia]

I think its because the destination is 2x2 area (All the times), so if you take that in account, you don't have to search all the ways, you can skip sometimes.

[@Koozmich]

I can't clearly understand: do the glue the wheels before the fast run?

[@suhu9379]

The contestant tried to clean the tire.

[@JuneJulia]

I wonder how the mouse knows how long he has been traveled? Rotations of the tire?

[@robertomessina1254]

Amazing, What technology they use?, genetic algorithms? AI?

[@markotikvic]

Maze solvers, A* (maybe), PID controllers, path builders (relying on ecoders) and maybe some accelerometers for slipping control (but I'm not sure if these are allowed for the micromouse contests). Maybe I'm wrong, but this is not AI, this is way cooler.

@@cguzmanxx my thought also. Given the noise there aren't any gears between the motors and the wheels. Still, they have amazing PID to drive this fast !
