Dagstuhl: Day 1 Session 2

The second session on Day 1 of the Computer Science in Sport Conference (Special Emphasis:Football) at Schloss Dagstuhl was dedicated to Robocup.

Sven Behnke (Universitat Bonn) introduced the session with some historical background about Robocup competitions. (Some of Sven’s publications can be found here.)

Bernhard Nebel (University of Freiburg, location 48° 0.822′ N, 007° 50.045′ E (WGS84)) provided further background about the origins of Robocup. He discussed sensor interpretation (inputs and outputs) and noted the importance of cooperative sensing.

Bernhard explored the ways in which robots can act cooperatively:

  •    Avoidance of interference
  •    Task decomposition and re-allocation
  •    Joint execution
  •    Dynamic role re-assignment

There are four roles for each robot in 4v4 Robocup: goalkeeper (fixed), active player, supporter, and strategic. Each role has a preferred location that is situation dependent. Each player computes the utility for each outfield role and shares it with the other outfield robots.

Bernhard discussed the development of table soccer as a micro-version of large space games. There is a commercially available table (National Geographic has a video about this table). This table uses a reactive scheme but Bernhard has been looking at anticipation schemes with decision theoretic planning. Recent research has simulated games between a decision theoretic system against a reactive system.

Sven and Berhard’s presentations stimulated a great deal of interest and questions.

Sven concluded the session with a discussion of technical challenges in humanoid robot design and performance (see, for example, Saskia Metzler, Matthias Nieuwenhuisen and Sven Behnke. Learning Visual Obstacle Detection Using Color Histogram Features.)

Dagstuhl: Day 1 Session 1

The Computer Science in Sport Conference (Special Emphasis:Football) started at Schloss Dagstuhl this morning.

Martin Lames is coordinating the Conference.

There is a list of participants here.

The first session was an introduction to Dagstuhl and to the Conference program.

Themes of the Conference include:

All these will take place in the context of the wonderful social environment of Dagstuhl and a number of unmeetings.

(A note about unmeetings (via Jay Cross):

New approaches create meetings that people enjoy, often organized in scant time, at minimal cost. Unconferences are characterized by:

  • No keynote speaker or designated expert
  • Breakthrough thinking born of diversity
  • Having fun dealing with serious subjects
  • Emergent self-organization
  • Genuine community, intimacy and respect)
