 Throughout this collaborative effort, TRADR enables the team to gradually develop its understanding of the disaster area over multiple, possibly asynchronous sorties (persistent environment models), to improve team members’ understanding of how to work in the area (persistent multi-robot action models), and to improve team-work (persistent human-robot teaming).TRADR focuses on an industrial accident scenario, but the technology is equally applicable for using robots in other disaster, emergency and urban search and rescue (USAR) scenarios, such as earthquake relief, as the TRADR deployment of robots in Amatrice, Italy, on September 1, 2016 shows.The goal of SHERPA is to develop a mixed ground and aerial robotic platform to support search and rescue activities in a real-world hostile environment like the alpine scenario.
