Why soccer?

[PerryMason]

I personally think that they should have robots competing to see who can complete a jigsaw puzzle first. It is completely unbiased and provides a test of both vision and dexterity, and both to fairly high degrees......but then what do I know?

Jugsaws are ok, but they are static.

Training an algorithm to react in a fast changing environment is much harder and realistic.

If we can put robots to work as a team in an hostile environment (such as a soccer game), we could also have autonomous robots working on mars and reacting in realtime to their surrondings.

Jigsaws won't work, its too simple a problem (no teamwork required, no changing scenarios in real time), but I agree that something other than Soccer could be a better test of the bots.

Personally I think SKIING would be an excellent test of bots. And it would enable bot builders to justify funding for trips to the alps every now and again.

Ever changing scenario, quick responses, weight balancing, gates to get through in difficult visual conditions. Different disciplines - Jumping, Downhill, Boarding etc...

Admitedly balance element would be a limit at the moment - but given time this could be hugely entertaining stuff to watch when they lose their footing!

Why Soccer? Because robots have a good chance to win.
It will make the organisers happy just like the IBM developers with Deep Blue. :-)

Here is the motto from www.robotcup.org
By the year 2050,
develop a team of fully autonomous humanoid robots
that can win against the human world soccer champions.

I don't really think it will take up 49 more years. If I were a professional (human) soccer player, I will run for life once the walking robots appear in the field (esp for the alpha/beta versions). That's not so funny to see big robots on rampage.

-- From the perspective of a survivor who got nearly run down by an out-of-control 100kg research robot. ;-)

Close to luck

[fireboy1919]

The general technique is to use an approximation of search (finding based upon luck) which tends to find good solution. Generally, it is based upon luck, and the only way to guarantee that its human-like is to restrict the search space to human-like possibilities. Whatever human-like means.

This is NOT the simulation of algorithms already created always, its often the creation of totally new algorithms, which can be extracted after development - a learning approach.

How? Straight statistics, support vector machines, decision trees, neural networks, fuzzy logic, and simulated annhealing are all common techniques to lead towards the goal. Who knows what they actually use.

Robot Emotions

[metlin]

A poster above had commented on Logical v. Illogical Actions. I'd agree with him, but what actually sets us apart is emotions, or instinct, however you may choose to call it since the two are subtly connected.

Robot emotions play a much larger part than most people know. In fact, any serious researcher into AI would know that emotions are nothing but another decisive factor, except that they are not well understood.

I'd seriously advice looking at Arthur T Murray's research into this area available here. It has a lot more to it than mere `entertainment` value.

And if you really are worried about robots having souls or a conscience, you should read this!. It is a pretty insightful article into what robots may have to do to qualify as humans.
