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. Our CoCoRo system consists of 3 types of robots. One is Jeff, a very fast and agile small autonomous swarm robot. This is an overview of its capabilities.
