Description

Introduction:

The L-M1/L-N1 series LiDAR adopts the Time of Flight (ToF) measurement method, capable of performing 360° 2D scanning and detection of the surrounding environment. With a maximum measurement frequency of up to 20,000 times/s, a measurement accuracy of ±3 cm, and a maximum detection range of 25 meters, it features strong resistance to intense light interference and is suitable for both indoor and outdoor use. All LiDAR models are equipped with a closed independent housing, supporting waterproof and dustproof protection. It is applicable to scenarios such as industrial robots, security and protection, industrial automation, smart logistics, and navigation obstacle avoidance.
 

Features:

1. 360° Omnidirectional Laser Scanning: 360° unobstructed scanning enables higher positioning accuracy and better mapping performance.
2. Dual Indoor & Outdoor Compatibility: Outdoors, it offers reliable resistance to sunlight interference. When detecting black/white objects, long-distance objects, and objects under direct intense light, it delivers more stable ranging performance.
3. Advanced ToF Ranging Principle: ToF-based LiDAR provides higher stability and superior light resistance. Equipped with a non-rotating housing, it is more aesthetically pleasing and lightweight, with overall performance far exceeding that of triangulation ranging LiDAR.
4. Full Support for ROS2: Fully compatible with both ROS1 and ROS2 systems, providing SDKs for both platforms along with relevant technical support.
5. Enhanced Glass Recognition: Delivers high reflection recognition rates for highly translucent objects such as glass.
6. Optional Ethernet Conversion Module: Utilizes Ethernet for data transmission, offering faster speeds compared to serial ports. It meets long-distance signal transmission requirements, saves USB interface resources, and can be directly connected to the Ethernet ports of main controllers such as Orin Nano and Raspberry Pi for data collection.
7. L-M1P-PHY Industrial-Grade Ethernet LiDAR: An industrial-grade Ethernet LiDAR that outputs data via Ethernet protocol without the need for a conversion module. It features significantly enhanced reliability, meeting industrial-grade standards.
8. USB Plug-and-Play: Based on the full-platform SDK provided, the LiDAR can be used directly after connecting to your computer via USB.
9. IP65 Waterproof Rating: Leveraging the ToF ranging principle, it completely abandons the traditional belt-driven design and is equipped with a closed independent housing.
10. Built-in Brushless Motor: Greatly reduces mechanical friction during operation, ensuring smooth performance with a service life exceeding 20,000 hours—more than 10 times that of triangulation ranging LiDAR.
11. Support for Dual-LiDAR Fusion: In environments with fixed obstacles, a single LiDAR may lose perception in certain angular ranges. Dual-LiDAR fusion compensates for this defect, enabling comprehensive environmental perception.
