  3. KRDL • Kent Ridge Digital Labs (KRDL) is a national applied research and development organisation established in January 1998 through the merger of former national IT institutes - the Information Technology Institute (ITI) and the Institute of Systems Science (ISS). • A repository of curious minds, the creativity emanating from a diverse team of more than 400 research scientists and engineers. • Five Research Labs - Learning, Knowledge, Ubiquity, Bio-Medical and Transportation Lab.

  4. Introduction • Our approach to the first RoboCup Pacific Rim Series (PRS) competition priortise on the research aspect of Robocup over development work. • We explored (1) multi-agent collaboration with strategical positioning, roles and responsibilities and (2) virtual global vision agents (3) Knowledge discovery agent. • Development work on (2) & (3) remains in the lab due to time-constraints.

  5. (1) Strategical Positioning, Roles and Responsibilities • Each agent has a strategical position that defines its default position and movement range inside the soccer field. • Two categories of positioning: (1) Initial and (2) Game-play (1) (2)

  6. (1) Strategical Positioning, Roles and Responsibilities (cont) • Goal-keeper: Positions in goal-mouth, prevents ball from going past, and distributes ball to team mates. • Defender: Positions in front of our penalty area, tackles for ball, and passes ball to midfielders. Wing-backs will in-charge of kick-ins in their own half. • Midfielder: Feeds forwards with ball and goes for the ball. Wingers will in-charge of corner-kicks and kick-ins in the opposing half. • Forward: Hard-press opposing defense for ball, strikes ball at goal.

  7. (2) Virtual Global Vision Agents (1) formulate a dynamic global map of the field by integrating vision senses of the distributed agents in the field. (2) The use of this information to best play the game, balancing team stamina, team workload and team. In a nutshell, we attempt to

  8. (3) Knowledge Discovery Agents In short, we do data (numeric) and textminingusing the rich and generous broadcast of the auditory and possibly visual information from the opposing team through the soccer server.

  9. Game Screen Snapshots S1. Initial Position (T-1) S2. Game Play Position (T-104)

  10. Game Screen Snapshots (cont) S3. During Game Play (T-779) S4. During Game Play (T-2647)

  11. Conclusion • Our debut participation in the Robocup simulation league focus on the strategic positioning, roles and responsibilities of multiple agents. • We hope to implement our ideas on (1) virtual global vision agents and (2) knowledge discovery agents in the future Robocup conferences.
