Rodent-inspired artificial whiskers enable touch-based drone flight
Researchers at Delft University of Technology have equipped a sub‑100‑gram drone with a pair of rodent‑inspired artificial whiskers that provide real‑time tactile feedback. Each whisker contains three miniature pressure sensors at its base, detecting minute deflections, vibrations, and pressure changes when the whisker contacts a surface. An onboard processing pipeline, using only 34 kilobytes of memory, filters out propeller turbulence to deliver millimeter‑precision depth data. Flight tests showed the drone navigating pitch‑black enclosures, mapping unknown rooms, and [...]
