SABER sets forth a novel idea of an autonomous multi-agent system of collaborative flying and ground robots. This idea will transform aerial delivery and data gathering systems for combat zones on land, sea, and air. The disruptiveness lies in the idea of using existing drones and ground rovers as part of a universal multi-agent system which enables scalability and cost-effectiveness. The SABER project will research hardware and software components as add-on solutions to existing robotic platforms enhancing their autonomous capacities for near real-time situational awareness and deliveries as an easy-to-use service. SABER's primary research question is whether it is possible to use the same technologies for a variety of aerial delivery and data collection needs, and thereby enable economies of scale and widespread adoption across capabilities for last-mile aerial logistics and data collection for situational awareness (SA). For impact, avoiding vendor-specific solutions helps to strengthen the European defence supply chain and beyond. To that end, the research outcomes hold significant spin-off potential both within the defence sector and in civilian applications calling for aerial data and point-to-point aerial deliveries.
