The RoboCup soccer simulation 3D league has taken a big step forward to the RoboCup’s ultimate long-term goal Since the 2007. The simspark with humanoid robots was used in RoboCup-2007. In 2008, the development of simulation 3D is heart-stirring. The better agent model, called Nao, has been used in the competition. In RoboCup-2008, 3Vs3 has been tested, and the competition of 4Vs4 is also actualized in China Open 2008. The simspark is an experimentally platform for researchers of humanoid robots behavior. Comparing with real humanoid robots, humanoid simulation environment has advantage in costs and convenience, so we can experiment on methods and algorithms for humanoid soccer behaviors in order to optimize them and apply results in real humanoid robots finally.
