Not really a short cut, since it's supposed to be a robo Tracer, since it didn't trace the line correctly when it moved, this should be renamed to Robo Tracer Slightly Fails...
Thats 4th?? What 1st place did then? Starts teleporting? Thats impressive. I guess the only way for it to be faster is if it turns faster at corners. This one slowed quite a bit before turning.
There are some cars that have quad rotor drone propellers flipped upside down on them for max downforce. Helps keep them stuck on the surface for the turns. This robot can’t go much faster without them.
I competed at the 2016 Japan robotrace, the difference between the top 6 places were all less than 200 milliseconds, the first place guy has been competing for almost a decade and basically his code and design is so extremely optimized that almost nobody can beat him. It's almost practically impossible to tell what actually makes him first place because there is a thousand variables to handle, everything from design, specs of part to programming itself. It's really cool to see 6 completely different designs come so close to each other.
I'm guessing because the robot isn't following the line exactly, kinda gliding over the slaloms and taking turns early. Maybe the rule is the robot cant come off the line at all which is why it has those two wings on the side of it. That's my guess.
@@NickFlightX that is correct. Contestant need only ensure that the projected outline of the robot is over the line at all times. So, on that long, wiggly section near the start, a robot could make a single continuous curve rather than slavishly follow every turn in the tack. It is quite difficult to do and is not at all common even though it could save a lot of time. You can hear how impressed the audience are.
For those who are wondering what the shortcut is, if you slow down the video you can see the path it takes is closer to a smooth curve on the wiggly section than following the line, which allows for far greater speed through that section.
Not going to lie, I thought I read it as "2019 Japan Lobster which runs short cuts - a real genius!" I am a little disappointed that I didn't get to see lobsters race.
Holy shit, I remember my old Lego NXT bot who would do the same. By the time the guy in the video had finished, that Lego bot would have barely made it to the first corner :D
I presume it uses nothing but cameras for guidance and you've got to make a bot that follows the track layout in the fastest time possible. The impressive part is how little it has to slow down to turn.
In my Western interpretation, the robot would have turned right at the first cross roads, then right at the next, and skip the whole hash section of the track, having learnt the course in the practice run.
I think the robot's only allowed to make a turn where one of those white dots are, so the title is kind of click-baity in that the robot never actually "cuts" a corner - it just takes them with a high degree of efficiency.
I've seen a couple of vids on this now. I believe they first make a run to get to know the track, and then use that knowledge to accelerate and brake at the right times. I also believe that's what this white dashes along the track are for: to tell the bot exactly where it is.
For people who doenst even know line follower robotics would probably be confused ahah, basically the robot is not squiggling with the line, rather it runs on a straight line, impressive if you ask me
@Private117 Thats just lucky you understand, you would be suprised if some people in the internet doesnt even know line follower is a thing, and stop being an asshole just because you understood better than others.
It’s understatedly impressive. Quite a large number of the racers that day didn’t even manage to trace the path correctly and got lost following the track. This one managed to follow the path while optimizing its trajectory to be as straight as possible. It’s quite good engineering and coding.
Yup, that's the most impressive cheating I've ever seen. It's like when the samurai action is to fast to take in.... Officials can't call a foul they literally can't see. Very nice my boy.
how is it cheating? foregoing the wiggly line is a time save and a damn good heuristic, where it can estimate the shortest path on the fly instead of following each of its subtleties and having to calculate an arc movement for each one.

Looks like first place is narrower i.e. lower moment of inertia allowing it to turn faster

It's so ingenious I even couldn't comprehend it!
Much more interesting if you included the exploration run.
link?
Why do you need exploration run for a line follower bot??
@@srikrishna_97 I could think of a reason like calibrating for friction on the particular surface...
@@srikrishna_97 if you know what's coming up, you can run faster. For example, you can speed up on the straights, and slow down before the turn.
@@chaklee435 True, make sense. Even that shortcut in the curvy section is possible because of the prior knowledge I reckon
ただのライントレースか...WHAT!!!!!!!!?????????????速過ぎるだろ......すげえ
To think this robot was only the 4th prize winner, the top 3 must be really fast
Super happy fun car!
For those wondering what this is: I'm wondering too
ooooooo
Oooooooooiii
i legit thought the car was going to just go backwards and pass the finish line
4th winner what does. 1-2-3 does??
Omen?
Long live The Algorithm
The tangent point is marked. The radii are constant.
thanks
This is a lot more impressive at 0.25x speed.
right i couldn't even figure out what i was watching til i turned the speed down like you suggested
Sounds nAughty
Is it taking shortcut? Or simply going too fast?
Is it Robot Racer or Robo Tracer?
you can do literally anything in Japan and then host an event for it
I have no fucking clue what I just watched, but I want more.
You watched this more than once
watch at 0.25x towards the end bits of the race, you will know what shortcuts are taken. gotta look VERY closely though.
Watch the entire run at 0.25x. You can see the nose of the bot doesn't stay on the line, but it cuts through the inside of some of the curves.
SUGOI!!!!
Holy shit, I remember my old Lego NXT bot who would do the same. By the time the guy in the video had finished, that Lego bot would have barely made it to the first corner :D
I watch it three times, did the racer use the shortcut? Where is it?
Play it at 0.25x speed. You can see on some of the curves it doesn't stay right on the line, but cuts to the inside of the curves.
especially in the zigzag part, it almost cuts straight through.
I still don't get it cause I don't know the rules of this competition, but I guess it is like the racing line of a race track?
I presume it uses nothing but cameras for guidance and you've got to make a bot that follows the track layout in the fastest time possible. The impressive part is how little it has to slow down to turn.
This was cool but I saw there was pre- training involved. It just made it less interesting to me
Oh i wanna learn this
smoooooth
0:29 this man is very pleased
Nice...
I have a question... Is it pronounced robo tracer or robot racer??
You know you are in Japan when people go "ooooooOOOOOOoooooo"

Where is the shortcut ? I saw it follow exactly all the line...
in majority of corners the robot dont exactly follow the line, taking a light shortcut so it travel less distance
@@brambl3014 it still did not finish first
What shortcut???
use video speed X0.25 to see shortcuts.
Okay i literally thought the robot will actually turn left right away and thats what they meant by shortcut... hahaha
I wonder where this technological advancement is going.
wow!
Everyone: oooohhh...

這是什麼比賽呀？感覺很厲害
dude who released the robot looks like freddie wong
Which sensor did they used ??
I don't know, but we use VCNT2020 from Vishay for such a small distance from the track.
Bruh.. what am I amazed at?
The short cut is the not long cut.
ah, just like* Lego mindstorms line following!
*barely, it’s flipping fast oml
sugoi
used to do this sort of stuff in middle school with lego bots. damn were we clunky :V
It took me forever to understand...
Do they have a priori knowledge of the track? It sure seemed like that car slowed down before entering curves.
I've seen a couple of vids on this now. I believe they first make a run to get to know the track, and then use that knowledge to accelerate and brake at the right times. I also believe that's what this white dashes along the track are for: to tell the bot exactly where it is.
@@tjoeker680 the dashes are markers for change of curves or straight sections
@@tjoeker680 that would make sense
wait where exactly does it run a short cut
0:11 and 0:23
try using 0.25 speed and see the direction and path travelled
Maybe where everyone goes "uuuuuuuuh"?
On the squiggly line segment, it doesn't follow the squiggles. It just goes straight over them.
For people who doenst even know line follower robotics would probably be confused ahah, basically the robot is not squiggling with the line, rather it runs on a straight line, impressive if you ask me

Verlo a cámara lenta y verán como toma atajos 😮
Faster than I run
Are short cuts allowed?
Yes, as long as the robot still touches the track.
Would have a shortcut if the robot ignored the inner lines
Molto bene grazie Evitaeterna.lñ.
👏👏👏👏
i didnt see any shortcuts
can i have i make this bot into an f-zero ship
I thought there was any "shortcut" not a "short cut"
He needs to teach it how to drift on corners.
...y'all are seeing the squirrel too right?
If you search the short cut, the women explains it!
I clearly see the shortcut....shortcut to more views
I'm impressed at how Japanese hosts manage to always overreact to anything
slaloms? chikanes? nani?
5 second penalty for cutting the chicane

@@chemieju6305 Yes, there were indeed faster ones, so fast that they didn't even use shortcuts to win
It skipped that last chicane. Otherwise that was a really good run.

Ngl waiting for the "NANIII" this whole time actually kinda disappointed
I'm disappointed. At 0:15 goes straight instead of taking a turn right, wasting 4 seconds on exploring a dead end.
Can someone explain the rules of this to me? When I saw "short cuts" in the title I thought the robot would do the same. Would that have been allowed?
So, why would a cheating robot be considered 'a real genius'? Shouldn't a robot play by our rules?
It is within the rules. I suspect that is why they made it so wide - so it can be technically on the line, while not following it exactly
