Drone Hides in Plain Sight Through Speed

Researchers have developed a novel drone, Phantom Twist, that utilizes rapid spinning to achieve stealth. By rotating at 25 revolutions per second, the drone creates a motion blur, effectively blending into its surroundings and evading visual detection.

This unique design emerged from a sophisticated, multi-stage automated process. A computer initially generated millions of potential designs, with AI then optimizing component placement to minimize visibility from all angles. A subsequent AI assessment, mimicking human sight, evaluated each design against various backgrounds, leading to the final, palm-sized, 30-gram drone.

Experts note that while the motion blur makes the drone hard to perceive, its effectiveness depends on the background color matching. The current design also faces limitations. Adding sensors or payloads would increase visibility, and scaling up the drone would create unmanageable centrifugal forces. Furthermore, its spinning nature severely restricts maneuverability compared to quadcopters.

While currently limited to a steady hover and audibly detectable, the research team believes further enhancements are possible. Future iterations may incorporate transparent components and refined AI design processes to reduce visibility further. The team is presenting their findings at the Robotics: Science and Systems 2026 conference in Sydney, Australia.
