The Year of CoCoRo Video #17/52: Lily confinement by bluelight

April 30, 2015


The EU-funded Collective Cognitive Robotics (CoCoRo) project has built a swarm of 41 autonomous underwater vehicles (AUVs) that show collective cognition. Throughout 2015 – The Year of CoCoRo – we will be uploading a new weekly video detailing the latest stage in its development. In this video we use blue-light blinks to keep the swarm together and to keep it in vicinity of the moving base station.

Due to this “confinement”, the radio-controlled base-station can pull a whole swarm of Lily robots like a tail behind itself. It is important to confine the robots into specific areas in larger water bodies because the swarm requires normally a minimum connectivity among agents to work efficiently, which is achieved only with a critical minimum swarm density. Without keeping the robots in a controlled area, robots could get lost and the robot density could fall below the critical density. Thus, confinement was identified to be a critical functionality.

To learn more about the project, see this introductory post, or check out all the videos from the Year of CoCoRo on Robohub.
