The robot soccer game system is a challenge for real-time control, which can be moderately abstracted from the standpoint of AI (Artificial Intelligence) and multi-agent systems. This simulator is developed for RoboCup Soccer Humanoid League. A humanoid robot belongs to highly intelligent system. The intelligent technologies of the humanoid robots include mechanism design, vision system, and algorithms in software programming. Therefore, its competitions can encourage creativity and technical development. To facilitate the strategy testing of these humanoid robot soccer competitions, a strategy simulator for kid-sized humanoid soccer in RoboCup is proposed. In this simulator, strategies compiled to DLL files may be explicitly loaded at run-time.
