During the first 18 months TRIFFID built the technical foundations of the system across mission planning, perception, human-robot interaction, human factors and system integration.
For autonomy and control (O1), the consortium developed a hierarchical mission-planning system based on a timeline-based planning and execution framework (PLATINUm) coupled with the ROXANNE reactive acting system, enabling dynamic task decomposition and real-time plan adaptation for both platforms. Autonomous navigation was implemented for the DJI Matrice 30T UAV (waypoint missions with GPS guidance and obstacle avoidance) and the Unitree B2-W legged UGV (SLAM-based navigation using LiDAR and RGB-D sensing with 3D mapping). An integrated safety-monitoring framework runs in parallel with planning, covering fault detection and a three-tier recovery strategy (dynamic re-planning, safe-stop-in-place and supervised return-to-base), alongside a resilient communications backbone combining Wi-Fi, 4G/LTE and Starlink fallback. These results are consolidated in deliverable D3.1.
For perception and situational awareness (O2), the team created the Incidents1M-Seg benchmark dataset — 170,272 annotated instances across 15,033 disaster images and 63 classes — and trained models reaching state-of-the-art accuracy: 95.58% mIoU for building-damage assessment on RescueNet, 95.80% mAP50 for aerial object detection and a gesture-recognition system exceeding 90% correct classification. Multi-modal sensor fusion extends perception beyond the visible spectrum, and an AR-based command-and-control ground station presents three complementary views (2D operational map, 3D LiDAR point cloud and AR-augmented camera feeds). These results are reported in D4.1.
For responsible integration (O3), a human-factors analysis using the EAST (Event Analysis of Systemic Teamwork) methodology characterised the task, social, information and knowledge networks of disaster-response teams, and a participatory-design toolkit was produced (D5.1). End-user requirements were systematically elicited and prioritised (D2.1) and realistic pilot scenarios for the three use cases were defined (D2.3).
For system building (O4), end-user needs were translated into a complete system specification and architecture (D6.1) comprising 43 functional and 8 non-functional requirements, and the hardware and middleware integration baseline was established (D6.2) including the selected UAV and UGV platforms, a combined RGB/thermal/LiDAR/gas/acoustic sensing suite and a dual-computing architecture (Intel NUC and NVIDIA Jetson AGX Orin). All reporting-period milestones were achieved on schedule, with individual modules validated in the laboratory ahead of system-level integration and the field pilots.
