Czech Republic. South Moravian Region. Brno. The International Defence and Security Technologies (IDET 2021) fair is an important defence and security technology show. In addition to supporting soldiers during their missions, Rheinmetall has integrated the quad-legged robot Rheinmetall Robotics L. The walking dog is a semi-autonomous quadrupedal unmanned ground vehicle, or Q-UGV. It has been developed with the subcontractor Ghost Robotics. The system can carry a wide variety of payloads for reconnaissance, protection, detection and other battlefield tasks, and is perfectly capable of operating in an urban environment. 6.10.21 © 2021 Didier Ruef
