The European Reference Network for Critical Infrastructure Protection (ERNCIP) and European Robotics group are partnering for a new robotics hackathon. The event will bring together roboticists and RN professionals & specialists to give a better insight into possible robotic applications for radiological and nuclear tasks. As common for software hackathons, ENRICH will contain a contest element, in which a panel of judges selects the winning teams. The main goal is to foster the development of robotic solutions for the RN domain. The trial takes place June 19 – 23 at the Zwentendorf Nuclear Power Plant (NPP), Austria.
