The RoboCup 2013 Drop-In Player Challenges: Experiments in Ad Hoc Teamwork

Patrick MacAlpine, Katie Genter, Samuel Barrett, and Peter Stone

To appear in the Proceedings of the IEEE/RSJ International Conference on Intelligent Robots (IROS 2014) in Chicago, Illinois, USA, September 2014.

The full paper can be found here.


This page provides details on Drop-In Player Challenges that were held at RoboCup 2013 in three different leagues: Standard Platform League (SPL), 2D Simulation League, and 3D Simulation League. In each game of the challenges teams consisting of robots randomly drawn from participating teams in the competition play soccer against each other. These "pick-up" soccer games occur in an ad hoc teamwork setting with no pre-coordination or knowledge of who ones teammates are beforehand.

Rules of the challenges and videos of drop-in player games can be found below.
