Its task: find and “rescue” two dummies and bring them outside. Some hundred meters or so away, Patrick Weiss is focused on remotely controlling the robot’s movements and its overlong gripper arm, while his colleagues Oliver Schulz and Patrik Bylin are glued to their monitors, watching the action unfold in the tunnel. The three of them, all from southern Germany, made up one of 17 teams from all over the world who entered the 12th European Land Robot Trial (ELROB), held on the grounds of Bundeswehr Technical Center for Land-Based Vehicle Systems, Engineer and General Field Equipment (WTD 41) in Trier in late June. Across five challenging disciplines with a military focus, the competitors tested their robotic systems to see how they would perform in real-world settings — and the results were mixed.
