Daniel Claes, Daniel Hennes, Karl Tuyls (all three Swarmlab, DKE, UM) and Wim Meeussen (Willow Garage, San Francisco, USA) have won the Best Demonstration Award at the eleventh international conference on autonomous agents and multiagent systems (AAMAS’12, June 4th – June 8th 2012) with: “CALU: Collision Avoidance with Localization Uncertainty”. AAMAS is the largest and most influential conference in the area of agents and multiagent systems, the aim of the conference is to bring together researchers and practitioners in all areas of agent technology and to provide a single, high-profile, internationally renowned forum for research in the theory and practice of autonomous agents and multiagent systems. CALU is a multi-robot collision avoidance system based on the velocity obstacle paradigm. In contrast to previous approaches, it alleviates the strong requirement for perfect sensing using Adaptive Monte-Carlo Localization on a per-agent level.
