Abstract

The RoboCup Four-Legged League is a robot soccer league where AIBO robots play in teams of four on a field of size 4m x 6m. In recent years the low level skills of the robots such as vision, localisation, locomotion, and ball handling have improved substantially and the games have become more exciting to watch. However, deliberate passing is extremely challenging and occurs rarely during games. This study investigates for the first time the impact of variations of global team strategies. The experiments employed the system used by the 2006 world champion team, the NUbots. The base strategy was compared against a more offensive and a more defensive variation. All test games were video recorded and evaluated using a variety of metrics including score, shots at goal, and ball position histograms. The results indicate that a team's style of play and low level skills are still the most critical parameters.
