Robocup 2002 Now Underway
ChenLing writes "Forget small robots on wheels playing soccer...193 teams from 30 countries have built androids to play soccer at 'RoboCup'. Although as the article says, it will be a while before we can pit androids vs humans on the same field....." Our previous story has background links and information about the contest.
I'm on the University of Virginia team, and we're in the simulation league. We don't have physical robots. The result is we don't have to spend the effort on mechanical concerns and image recognition, and we get to devote more effort to the AI aspect of the competition. In the simulation league, the robots DO get tired, they do miss shots, and they have imperfect information. The idea is to remove all physical considerations from play and have them win on intellect alone. The robots being used in competition are no where near the level required to beat a world cup team, but I imagine that once they get close, these "humanizing" factors will be added to keep the match fair. At the current rate of development, I expect this to be well before 2050.
I didn't realize robotics had gotten anywhere near this point. I think a lot of people underestimate exactly how hard it is to get a robot to do something like, for example, find a ball. Now these robots are walking (a significant challenge, from my experience... :) kicking a ball, and interacting with each other? Pretty incredible.
I wonder how sophisticated these humanoids can get. Can they pick themselves up if they stumble? Can they figure out whether another robot is on their team? Can they pass? The article seems to imply that at this point, they're not that much more than glorified mechanical penalty kickers.
Or, if the programers were smart, to only commit them when the ref was looking away

recently i watched a PBS (i think) special on the Robocup...must've been from 2001, if the 2002 one is going on right now...it was hosted by Alan Alda...anyway, it was really interesting...
some of the things the teams could do were amazing...while most teams basically used "brute force" to push the ball into the net, there were some advanced teams that could actually recognize teammates and pass the ball to them...that was pretty impressive...the had kind of a pinball type flipper kinda thing that would poke out near their feet...
another cool thing was that some of the robots (i think it was the same team that could do the advanced passing) could actually "trap" the ball...they had a spinning bar on their front, so as the ball came to them, the bar would spin, and they could keep control of it, by basically continually spinnning the ball towards themselves...kinda like a tread mill...
another progressive idea (and i'm sure the slashdot/open source community will appreciate this) was that after the competition is over, all of the teams are required to share their source code, so everyone starts on the same plane for the next year of research... it's really a cool speical if you can catch it while you're flipping the channels sometime....
"Facts are meaningless. You could use facts to prove anything that's even remotely true." - Homer Simpson
1. A robot may not score on his team's own goal, or, through inaction, allow his team's goal to be scored upon.
2. A robot must obey the orders given it by coaches except where such orders would conflict the First Law.
3. A robot must protect its own field position as long as such protection does not conflict with the First or Second Law.
Ok, I'm not there but as far as I know android team v. android team is not being done this year, contrary to what the article is insinuating.
According to the Official 2002 Robocup Humanoid League Draft Rule there are three catagories of Current and Future events with several sub-sections. Here is the run down.
* Standing Still on One Leg
* Humanoid walk - out from one end, around a pylon and back,
* Shoot - where the bot is able to shoot on the goal and get it in.
* Penalty Shootout
* 1v1, 2v2, 3v3 Soccer
* Freestyle - Five minutes of judged performance art.
According to the organizers they are just hoping to get some teams to try the first few! And as you can see the competitive playing of soccer is waaaaaaaaaaaaaaayy down the list and probably aren't even being attempted this 'Cup. Sure, those nice posed shots of those Sony bots look nice, but those aren't competition pictures. Sure, the information on the Official Robocup site is sparse, but don't you think that they would have some big announcement if it did?
This article from MSNBC is confusing one league (the humanoids) with another (the non-humanoid) in an attempt to create hype. Personally I think Robocup deserves it, but not by misconstruing what's going on.
The best thing about the Robocup site is that you can actually watch the replays of the simulation games with Flash. Pretty sweet.
