A video shows a person wearing an orange jacket disappearing, prompting the question of how well they can hide. The footage was captured at the University of Celje, where researchers are developing unmanned aerial vehicles. These drones are capable of navigating autonomously without relying on GPS signals. The team tests their concepts in real‑world conditions at a dedicated research centre. During a visit, the investigators demonstrated the technology’s ability to operate in complex environments. The experiment aims to advance aerial robotics for scenarios where satellite navigation is unavailable.
