Hyper fast robot line following

[gunmanscotland]

Wot the fuck...my robot is faster than your robot....lmao these people are so easily amused.

[frackcha]

so they copy the design of the chassis... if it works, why change it!!!

its the electronics, and how they communicate to the chassis that counts..

[Me102288]

I dont notice them taking turns outside inside outside... define the width of the track and program them to cut corners... kills a bunch of time.

can they be programed to accelerate or slow down by identifying the degree the white line is bending ??

I'm into racing no robotics.. if ya couldn't tell .. lol

[BrutManDave]

Or you could just buy scaletrix.

[asanchez1103]

Shouldn't this mean that we should be implementing this into cars by now?

[LXBD]

They look like the robots from the movie Wall-E :D:D:

[MainlyMainly]

wonder if hes on robot cocaine

[fiddyschmitt]

i for one welcome our new robot overlords

[Shocker9]

Isn't this a programming contest since everyone appears to be practically running the same kit?

[MrMinidude4]

OOOOOOOOH a lightsabre! oh its your like bar...

[hipersons137]

@darthspeaks

We could find out earths mysteries like trace nazca lines in Peru or they could do all the dangerous jobs like mining. Robots really can do anything!

[darthspeaks]

I love watching robots evolve! Someday many things will be done automatically with the help with robotics - everyone will have a beautiful lawn and landscaping. Everyone will have their floors clean every day with robots vacuuming at night silently. You have a knot in your back? The automatic masseuse will massage your back! No more paying through your nose for this pleasure.

[kubarebo]

It's boring, all the robots on a shelf visible at 2:01 seem to use same basic design. No innovation at all. It seems like everything was done from same kit...

[palmisano]

@kubarebo no kits, but yea, everyone copies the winning design from previous years . . .

[kubarebo]

@palmisano Where's the fun in *that*? Copying only goes so far...

[palmisano]

@kubarebo no fun in losing either =P

[kubarebo]

@palmisano It's entirely counterproductive, it's more like a cargo cult than engineering... Who says you'll lose if you do your homework. Quantify the performance of other designs, then come up with a fresh new thing that does better. That's where fun's at. Methinks line following can be done down to the limits imposed by wheel-surface coefficient of friction, at least after one pass. What I saw in the video was seemingly far from that. And I did motion track a few runs off the video.

[palmisano]

@kubarebo Don't get me wrong, I think the competition should be changed if an optimal design is copied by everyone and can't be improved upon. I wouldn't compete myself, with such little remaining room for creativity. btw, wheels aren't allowed for the race.

[kubarebo]

@palmisano If you can't have wheels, you need accurate actuators that can maintain static friction at the "foot" where it contacts the ground. Using rotating cams like they do here is silly, and you can see that they are sliding all around. To get these robots to perform well, you need to do almost everything exactly differently from the solution we can see here. You need legs with contact force sensors to maintain zero slip, you need low center of mass, etc. This "competition" is mindless crap.

[Liamspero]

@palmisano when u build one THEN you can bitch about one.

[ez2animate]

@kubarebo If you take the best design so far, and improve upon it what do you get? An even better design. Who needs a more creative way when you have the best and most efficient already? Not saying this is the best, but just stating why it makes sense to copy the design.

[kubarebo]

@ez2animate How do you know you're not reaching some local optimum? The global optimum may be way better, but is far away in your solution space. You have to explore, otherwise you get diminishing returns. The particular designs we see here are crippled by low resolution of the sensor and high moment of inertia about vertical axis. They are also unnecessarily tall, possibly enabling roll-over. They also seem to be using a control algorithm that would have been state-of-the-art 50 years ago :)

[ez2animate]

@kubarebo Yeah no I totally get where you're coming from, I was just trying to justify the re-use of a concept. If you take the best concept at the moment, and make it better, that's a lot faster than finding a completely different one that takes time and energy. But once you've exhausted the possibilities then you'll be forced to come up with a new design.

But besides, there's always some guy out there that has to be different ;P

[1weside]

@kubarebo boo who snivling baby

[TechnoInformation]

@palmisano if everyone copies the design from previous years then the design will never ever change, because all the designs are the same.. Just saying!

[slowpoke96Z28]

@kubarebo hmm. they say the same thing about nascar. yet some teams seem to win while others don't. gues there's more than meets the eye...

[quaditz]

@kubarebo They are from Singapore, they get a bonus when they copy it :D

[lazerusmfh]

So... Why are they doing this at a track?? Take a robot, and put in on the bike lane white line on the side of the road, see how far it goes.

[luisvoid13]

what's a rotating cam? how does it make the robot move?

[palmisano]

@luisvoid13 google has all the answers, my friend =P

[iamgodlike91]

how did the IR sensors so good...i made my robot from cytron using IR sensors as well and it sucks alot while tuning it.

[ThePingPanTher]

แรงสั่งฟ้า ข้าสั่งลุย

[Joreen95]

Hi can I invite you to Robo Games?

[palmisano]

@Joreen95 Sure . . .

[erikd217]

Super speedy robot

[MechanicalStagfish]

Alternatively, you could use scalextrics.

[AunShovah]

It's a lively one!

[TrickyNekro]

And some time after fast and the furious Tokyo drift we have...

The PID and the H-bridge: Singapore drift...

Yeah!

[bolestar]

upgraded bristle bots t(-.-t)



[hassanabbasbirmani]

if we gave them car body thnk about it .........

[TheBl4ckPhoenix]

Drifting Robots.

Now,yes, we are really fucked.

[FEARcactus]

Think Wall-e

[Understandable666]

That's cool now try doing it with cars.

[YouSoPorker]

but will it blend?

[Sadokun23]

@YouSoPorker I see that coment on every video. What does it mean?

[Dino22Dan]

hold 3 then 4 you will see a warping bot

[MrAndrewlarson]

the future of darpa!

[dylanxmazoch27]

that things drifting

[kosilveriarn]

White can of spray paint $5, map of the complex printed on paper $1, stealing these robots by running through the demonstration spraying a white line along the ground and out to your car.....epic.

[noobmaster31]

You guys put my robot to shame. Mine travels like 25% of your robot speed and the treads (I use a traxster robot) always break.

[k1ttys]

lol they look like bugs drifting

[Evi1M4chine]

How many legs do they have?

[palmisano]

@Evi1M4chine None. Its sticks on rotating cams.

[omgitsrez]

LOL never thought that legged robot can drift

[PAVONEZORZ]

INITIAL D?!

[findharsha]

Looks like the robots are already programmed with map!

[tascheri]

at first, I thought it had wheels...

[mindstormsNL]

i think it drink to muck cafeine

[minyaaak]

crash please !

[notexactlyIO]

I learned something just now: it's possible to drift without wheels!

[pkpgpk]

I love how it drifts. :V

[NeverOffLimits]

I wanna see them crash.

[watwat79]

Looks like the little robot from the Transformers movie. Awesome!

[TiagoTiagoT]

Things need to get seriouslly cheaper so we can have schoolkids building monster trucks that run crazy like that on their own!!

[amara17]

cooooll robot !!! really awesome ... :) compared 2 this 1 ours was like .... a turtle..... :( ... but still for an al girls project... it was good!!

[CROUCHINGCOUGAR]

RUN FOR YOUR LIFE PEOPLE! RUN!!!

[sparkysparkpants]

@CROUCHINGCOUGAR it runs to fast for people, did you not her palmisano? it runs on premium squirrel juice!

now robot, get me the newspaper!

[Ropinlizard]

Ultimate Pet

[dudealive1]

one day using this same type of technology our everyday cars will have auto pilot.

[leon0862]

common crash already

[bestamerica]

'

why NO wheels

[jeetendrag10acc2]

it moves too fast..i can't see: are these hexapods or wheels???????????omg..awesome!­!!!

[CROUCHINGCOUGAR]

@jeetendrag10acc2 hexapod

[thadx123]

LOL i live in s'pore. Wish i could have seen it in action.

[cardriver222]

that is better than micromouse

[cardriver222]

AWESOME!!!!

[cardriver222]

AWESOME!!!!!

[youtubasoarus]

Get that line Robot. GET IT!

[shuwukong]

do you know why people don't make a hexapod a vehicle? coz the driver will be shaken to death

[thetigerevil]

They're drifting :))

[ninja6kid]

mind = blown

[MultiAf11]

HOW THEY MOVE?can u pls tell me?

[lenzub]

thats nuts but maybe magnets to help it stay on the track?

[jchowrules]

How do they move??

[nicodanger13]

Run, Baby, run

[Timgeo84]

looks like a mountain goat chasing a deer

[JaredAredRed]

that thing looks like it might kill someone

[MaxC17]

so basically one day we don't need to drive? oh man... i wanna drive...

[UnluckyGambler]

@MaxC17 ull still have the option of driving, im sure. future cars wont be able to hit each other, theyll have sonars detecting other objects around them.

[RDCST]

It haves wheels or legs? It's so fast I can see it.

Maybe you can modify a Skyline and race against a human drifter. :P

If you do that, please, I wan to see it.

[rmazing]

there's illegal plutonium or something isn't there?

[palmisano]

@rmazing They run on premium squirrel juice.

[MrTpengineer]

@palmisano I use the super :)

[eVITORIOe]

DRIFT !! :D

[zeromra]

hahaha it's going so fast that it practically drifts around the corners!

[Aznnvazn99]

I wanted to see robots overtaking each other like a race.

[ans0njac0b]

btw, ter was no rotating cams on these robots

[jpap967]

That truly is impressive... They walk so fast!

[DeathStrawberry15]

If you put blades on that thing it would be freaking scary.

[ZeroBlitz36]

Thats crazy fast O_O. I saw some other hexapods on youtube , but these are like dragsters

[QcLoneWolf]

Incredibely fast actually for a walker

[rejoiceJennt]

yo! that's insanely fast!

[mog123noblog]

What's this robot called? does he have a homepage?

[magzinerack]

the robot is called legged marathon robot

[TCCHowie]

OMG of course they scan the line !!!!

Would make no sense if not !!!

n00bs

[nnieznan]

Maybe robots doesn`t know path before race. I think that they can scan and remember it in the fist lap.

Do you agree?

[magzinerack]

infact the path is fixed, however, they still use sensor to sense the line that use the line as a navigation

[kakkanekukkane]

huh? is this somekind of drift race?

[dillydean]

so have they got wheels?

[palmisano]

nope

[iSkyProducciones]

@palmisano and wath they have to moove??

[palmisano]

@iSkyProducciones huh?

[iSkyProducciones]

@palmisano if they havent wheels... what do they have?

[palmisano]

@iSkyProducciones cam driven legs

[Bedulonko]

Maybe in the future cars will work like this, so we won't have the drive anymore. The streets will have those lines, and your car will just follow them to the point you want to reach... Who knows,but if there's something i'm sure about, is that cars won't fly, at least not in the next few or ten-twenty years.

[fassenkugel]

future? my accord do this till 3 years ago..

[Bedulonko]

lol I mean every car, and you know what I meant. Why do you want a car like that if all the others are still driven manually? I would by kind of dangerous, you know? "You" would be driving perfectly, but the others would still drive bad. Anyways, it's impssible to guess what we are going to use for trasport in twenty years more, but it's fun to think about it.

[fassenkugel]

it is not dangerus, because the accord have radar aided tempomat. keep safe distance from other cars, and the camera on the mirror keep on the way. ofc this feature is not for city traffic, but work well on highway.

[mop65]

Never thought I'd see a legged robot getting oversteer! Get it a pair of Nikes!

[akeithkira]

was that a legged robot or wheeled robot? what was the rotating cams for?

[8Ecnelis8]

legged

saw something like that on TV

the idea is taken from some insect

[smashingparadox]

that's really impressive!

[jigglesnap]

Are they allowed to memorize the track?

How long until we have cars that drive themselves? :)

[palmisano]

nope just basic line following

[molinobeer]

I'm sorry but that's not line following.. sometimes they get all of the line and still turn to the right direction...

[wesajarjar]

@molinobeer but they adjust to get back on the line O-O

[molinobeer]

ok, but on line following contests this is considered traject programming before the race...

[wesajarjar]

@molinobeer im not relly following u i know what they are soppost to follow the line, but is there some kind of rules to these things?

[molinobeer]

they must not know the path before the race, and looks alot like these robots on the video are programmed to follow a predetermined path.

get it? ..or my english is to bad!?xD

[wesajarjar]

@molinobeer so u think they were cheating?

[molinobeer]

@wesajarjar

no, i don't don't what was the pourpose of this contest, i'm only saying that i think this video title is wrong..

[wesajarjar]

@molinobeer oh so u think it was just a race and not line following? because to him it might look like theyre following the lines on the track, but i can seewhat u mean the way they go off the line and still turn and stuff

[molinobeer]

yes, I think that the white line is there just for punctual calibration of the robot position... seems alot they are not following the line.

[wesajarjar]

@molinobeer ok i see what u mean. well sorry for cousing u trouble and wasting ur time. but i think this is cool either way

[molinobeer]

@wesajarjar

lol, no prob.

[magzinerack]

in fact they are following the line,welcome to singapore robotic game 2010

[wesajarjar]

@magzinerack oh well i just had this long convo with molinobeer so i dnt know who to listen to

[magzinerack]

In fact I am one of the participant

[wesajarjar]

@magzinerack really? sounds fun. how much do those cost?

[ans0njac0b]

@wesajarjar arnd S$3000 + all ur hard wrk and time

[molinobeer]

I will be making the nationals, them i will see if i get in there to... i will spread the news..

[KuroTempest]

neat

[MyCarlover]

wow robot drifter

[pludrpladr]

exactly what i thought... soon well have line following robot races :D

[gabydewilde]

Very cool, they go pretty fast, could perhaps go even faster if they would look around the corner and remember the shape of the track if that is allowed. R R L R L L R until a match is found. They also approach the corners the wrong way.

Wish I had the money - lol

[TrickyNekro]

Man.... they drift.....

[Productopunto]

It uses a PIC?, i'm building a line following robot, how you deployed the steering?? it seems so efficient. Im using a PIC16F877A IR CMY70 sensors, DC motor's for propulsion (back). Please help in the steering!!

[palmisano]

oh its not my robots, and they just used differential steering . . .

[Productopunto]

thank's man!

[giannis400]

thats some scary shit...maybe a 100 yrs from now, robots will rebel against humanity and destroy us all.

[Gamerdudeeee]

dont be afraid ull be dead by then

[m23402027]

i am pretty sure that it must be implemented PID control algorithm :)

very nice!

[superchiku]

wow man..

[EthernalsabreX]

Does it have wheels or legs? I can't quite make it out from the vid.

I guess wheels cuz their so fast but still, Are we that far yet?

[rswamy85]

just legs..no wheels...

[arixrobotics]

do you know how those sensors work? how come they are not directly above the floor like always?

[palmisano]

They aren't just normal IR sensors. I'm not entirely sure what the physics behind it is, but its long range and can report back the difference between black and white.

[Igotocostarica]

its like star wars

[NYVonix115]

Beautiful, look at them go! =)
