RoboCup 1999 brought the Simulation League to Stockholm. I competed with RoboLog, the University of Koblenz team, alongside Frieder Stolzenburg, Jan Murray, and Björn Bremer.

No contemporary photograph specifically identifying the RoboLog team has yet been found, but Tomomi Kawarabayashi’s surviving album provides a valuable record of the Simulation League site and several participants. The original album captions and full provenance are preserved in the accompanying sources.yml file.

The recovered material also includes original 2D Simulation League game logs. The three match images below were reconstructed from those logs in 2026; they are not contemporary screenshots.
