The Unitree 4D LiDAR L1 is described as the industry’s first omnidirectional ultra-wide-angle bionic 4D laser radar, priced from $249. It measures 75 by 75 by 65 mm and weighs 230 g with 360 by 90-degree scanning at 21,600 effective points per second (43,200 sampling). Available in PM (Precision Measurement, 20 m at 90 percent reflectivity) and RM (Remote Measurement, 30 m at 90 percent reflectivity) variants with ±2.0 cm accuracy and 0.05 m minimum blind spot. A built-in 3-axis IMU supports open-source SLAM using only point cloud and IMU data. It resists over 100 KLux outdoor ambient light with effective glass detection. Non-contact brushless rotating mirror scanning operates at 11 Hz circumferential and 180 Hz vertical frequency with TTL UART communication. Power consumption is 6 W. It is Class 1 eye-safe. Unitree claims it achieves the same effect as traditional LiDAR at less than one-tenth the price. Targets research applications for small to medium mobile robots.
