The idea of
Robot Soccer
What is AI?
Research in AI includes:




design of intelligent machines
formalization of the notions of intelligence and
rational behavior
understanding mechanisms of intelligence
interaction of humans and intelligent machines.
Objectives of AI
Engineering : costruct intelligent machines
Scientific : understand what is intelligence.
Can a robot do these?
Understand?
Simulate its environment?
Act rationally?
Collaborate and compete?
Display emotions?
A bold claim:
A team of Robots will beat the FIFA World Cup
champions by 2050!
RoboCup - Aim
”pushing the state-of-the-art”
”By mid-21st century, a team of fully
autonomous humanoid robot soccer
players shall win the soccer game,
comply with the official rule of the FIFA,
against the winner of the most recent
World Cup.
TO BOLDLY GO WHERE MAN HAS GONE
BEFORE (cf. Star Trek)
Formalised Testbed
Do you really believe that a team of Robots
could beat the FIFA World Cup champions by
2050?
By all accounts this may sound overly ambitious.
In fact, if you compare this goal to other ground breaking
achievements it is not ambitious at all.
The Wright brothers' first airplane was launched and 50 years
later man landed on the moon.
Even more recently Deep Blue the computer programmed to
play chess, played chess grand master Garry Kasparov and
won -- roughly 50 years after the deployment of the first
computer.
It's a long time.
Think what has happened since 1950.
Power of AI
Is the following AI?
In 1997 a computer, Deep Blue, won a chess
match with world champion Kasparov.



Accident?
IBM paid Kasparov to loose?
Brute force with no intelligence?
So, what is intelligence?

Intelligent Agents
Agents are situated


Perception of environment
Execution of actions
Agents can communicate and collaborate


they can differ

egoistic/altruistic
The agents have:



objectives,
communications,
intentions.

World is two-dimensional.
Players are points.
Simplified control of movements
No collisions and conflict solving.
Simulation of soccer using artificial
intelligence programs.
Each team consists of eleven autonomous software
players.
Sophisticated rules apply in this league.
Simulation League
Each Team consisting of 11 programs, each controlling
1 of 11 simulated team members
The game takes place on a soccer software server
Motion, energy and distributed sensing capabilities are
resource bounded
Time 11 minutes
Communication is available between players and strict
rules are enforced e.g. offsides
Mainly for researchers interested in complex multiagent reasoning and learning issues but don’t have
the resources for building real robots

No communication, autonomous robots, software
only. Legged Robot League. 2.8 m x 1.8 m
2 players and 1 goal-keeper in a team
Sony Legged Robot League
Is played on a field, approx 3x2 meter
Sony develops the robots, and provides a
interface for the programming of the robots.
•No Hardware
modification is
allowed
Playing time is
10 minutes per
half, with a 10
minute break at
halftime
Do different Robots have
different personalities?
Some teams have robots with very
different capabilities.
But it is hard to think of them as
having personalities;

rather the robots have different
playing styles.
Early Sony prototype

Robot movements closely mirror those of
animals
•The winner is the team
that scores the most
goals.
• In the event of a tie, a
sudden death penalty
kick competition will
determine the winner

The Legged Robot League
If opposing teams'
robots are damaged or
play is excessively
rough (whether
intentional or not),
penalties may be
assessed to the
offending robot

RoboCup-Rescue Simulation Project is a new practical domain
of RoboCup
A new initiative on search and rescue for large scale disasters
A generic urban disaster simulation environment constructed on
network computers
Heterogeneous intelligent agents such as fire fighters,
commanders, victims, volunteers, etc. conduct search and
rescue activities in this virtual disaster world
Goal: to enlighten citizens about accurate damage predictions,
decision support in real disasters, and emergence of better
disaster prevention strategies

Problems
1. Propose other robot sports in addition to
soccer and sumo. Wrestling? Volleyball?
Fencing? Write the rules and design a robot to
play them. What will be technical and what will
be the scientific challenge.
2. Design the rules for walking robots playing
soccer. Design the field. How to control the
camera. Do we need sensors and for what?
Where are they located?
