YDLIDAR TW3 Underwater Green Laser LiDAR, 360° Scanning Range Finder, 4000Hz Sampling Rate, 0.05-5m Detection Range, IP68 Waterproof, for Pool Cleaning Robot Navigation and Obstacle Avoidance

YDLIDAR TW3 The First Mass-Produced Consumer-Grade Underwater Green Laser LiDAR Solve Underwater Perception Challenges Traditional infrared LiDAR and cameras fail underwater due to light refraction, surface glare, and turbid water causing positioning drift, obstacle avoidance failures, and inefficient cleaning. The YDLIDAR TW3 changes the game. Green Laser Technology for Superior Penetration Unlike 905nm infrared, the TW3 uses a 520nm green laser (Class I, eye-safe) that cuts through suspended particles and resists intense ambient light up to 100Klux. It delivers stable ranging from 0.05 m to 5m in pools, even under direct sunlight or in murky water.

360° Precision Scanning for Smart Navigation 4000Hz ranging frequency & 612Hz adjustable scan rate ±50mm accuracy & 0.54 ° angular resolution Distortion-free point cloud with 360° field of view Enables pool cleaning robots to achieve centimeter-level real-time mapping, autonomous path planning, and full-coverage cleaning no missed spots. Built to Survive Harsh Pool Environments IP68 waterproof operates at depths of 0.5 to 5 meters Chemical-resistant materials withstands chlorine, salt, and oxidizers (passed 30-day immersion tests in 5% NaCl & trichloroisocyanuric acid) Dual-sealed housing no leakage, no corrosion
