The Fairy is a next‑generation, high‑precision mid‑range digital LiDAR built on RoboSense’s chip‑based transceiver architecture and fully digital design. Compact and lightweight, it delivers industry‑leading 0.5 cm precision, supports up to 96 beams, and outputs a high‑density point cloud of 1.37 million points per second. With its 360° × 32° field of view and 150 m detection range, Fairy provides structured, algorithm‑friendly point clouds that enable real‑time object sizing, shape recognition, and distance measurement, making it ideal for 3D mapping, obstacle avoidance, and autonomous navigation.
Equipped with active illumination technology, Fairy maintains consistent performance regardless of ambient lighting. It operates reliably in nighttime, strong light, rain, and fog, ensuring stable perception data even in challenging environments. This robustness significantly improves a robot’s adaptability and supports high‑reliability perception in complex real‑world scenarios.
