A demonstration involving L3Harris Technologies and ARX Robotics UK showed that passive counter-drone sensing can now be performed from uncrewed ground vehicles (UGVs), potentially reducing personnel exposure in hostile or hazardous areas.
The trial took place during Project Convergence-Capstone 6, an event organised by the US Army to assess new technologies and future operational approaches.

During the event, the companies integrated the Corvus-Raven system, a tactical counter-drone technology from L3Harris, onto ARX Robotics’ remotely controlled ground vehicle, to demonstrate how robotic mobility can extend the reach of counter-drone sensing.
According to L3Harris, Corvus-Raven passively detects signals associated with unmanned aerial threats and provides bearing information to operators, which can help enhance situational awareness on the battlefield.
During the demonstration, the counter-drone sensor was carried by the ARX robotic platform into forward positions, transmitting threat detection information to operators at a distance.
The companies stated that this approach enables repositioning of sensing equipment as mission needs change, allowing for a flexible response to potential drone incursions.
L3Harris Global Spectrum Superiority UK managing director Nicky Tabram said “Our collaboration with ARX Robotics UK demonstrated the value of combining proven mission capabilities with innovative robotic technologies from across the defence ecosystem.
“By mounting Corvus-Raven on a remotely controlled uncrewed ground vehicle, we explored how operators could extend passive sensing into forward or hazardous areas, enhance situational awareness and reduce personnel exposure.”
According to L3Harris, Corvus-Raven features an open architecture, supporting integration with command-and-control and battle management applications and the generation of TAK-compatible messages to update a shared geospatial operating picture. The system also offers the option to provide an integrated electronic defeat capability.
The demonstration was cited as evidence of how modular, open-architecture designs can accelerate the integration and assessment of complementary technologies.
L3Harris reported that lessons from the event will help shape future developments and create further opportunities for combining counter-drone and robotic ground systems across different missions.
