Desktop Robot Soccer
Robot soccer pits teams of fast-moving robots in a dynamic environment (Sng et al., 2002). Robot soccer fosters AI and intelligent robotics research by providing a standard problem where a wide range of technologies can be integrated and examined (Asada & Kitano, 1999). Today two international robot soccer federations, RoboCup (RoboCup, 2007) and FIRA (FIRA, 2007), organize competitions in an eclectic range of categories. Those competitions are accompanied with technical conferences. The first international robot soccer tournament MiroSot'96 was held at Korea Advanced Institute of Science and Technology (KAIST), in November, 1996. At the time of writing, we can count more than ten different robot soccer leagues from RoboCup and FIRA. Taxonomy of the robot soccer leagues could start with the vision system used. The global vision group contains all the leagues that allow a global vision system (camera that gives an eye-bird view of the playing field). The image processing is done on a PC that controls the robots via a radio link. Whereas the local vision group contains all the leagues that require the vision processing to be done on the robots themselves. In this second group, the robots achieve a higher level of autonomy. Only wheeled robots are used in the global vision group. Whereas, the local vision group can be subdivided into wheeled robots and legged robots. Finally there are simulation leagues that provide a test bed for multi-agent research for those who do not have access to real robots. Robot soccer not only stimulates robotic research, but also provides a platform for computational intelligence education that allows the development of engaging undergraduate level assignments. However, there are several limiting factors for the widespread use of robot soccer as a research platform or a teaching tool. Most robot soccer leagues like the popular RoboCup Small Size and FIRA Mirosot leagues require a large playing field and a team of several postgraduate students to build the hardware and develop the complex software. The least resource-demanding robot soccer league is the simulation league. Unfortunately, by its very nature, this league does not provide the invaluable experience of real robots. With the constraint of using real robots, the least resource-demanding robot soccer league is arguably the FIRA KheperaSot league. This league represents Desktop Robot Soccer, in the sense that the playing field fits on a desktop or a computer laboratory bench. The regulations of the KheperaSot league impose size restrictions on the robots. The size limitation lowers the entry barrier for participants in relation to other robot soccer tournaments, making it more accessible to individuals and small teams with modest funding and infrastructure support. The size limitation also poses challenge for hardware technology. It pushes the limits of how much processing and sensing can be put into the small package at a reasonable cost. However the size is not as small as to requiring miniaturisation technology beyond the reach of standard electronics and construction techniques. The KheperaSot league was the first fully autonomous robot soccer league of FIRA.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
