Overview
WLR-720 is a 16-line Mechanical LiDAR (Yahboom / VANJEE / WANJEE Technology) based on the TOF (Time of Flight) ranging principle, designed for 360° panoramic scanning and environmental 3D perception. It supports up to 120 m scanning radius, provides high-quality raw point cloud data within a 30° vertical field of view, and integrates a built-in 6-axis IMU for outputting angular velocity and acceleration data via PC software/host computer. Typical applications include navigation and positioning for low-speed vehicles and robots, outdoor high-precision map drawing, and obstacle detection.

Designed for obstacle detection and navigation on low-speed vehicles such as delivery robots, forklifts, and mobile platforms.

ROS SDK and supporting tools help you bring point-cloud data into common robotics workflows faster.

Ready-to-use navigation and mapping routines accelerate testing in a ROS environment.

Supports multiple 3D mapping approaches such as Lego-Loam, Cartographer 3D, A-Loam, LIO-SAM, and more.

Autoware.ai adaptation enables building mapping and navigation pipelines for autonomous applications.

Time-of-Flight measurement uses laser pulse timing to calculate distance for accurate point cloud generation.

A 16-channel layout covers a -16° to +14° vertical field of view for more complete 3D scene capture.

The built-in 6-axis IMU provides angular velocity and acceleration data for improved motion compensation.

A sealed protective cover helps the LiDAR operate more reliably in dusty or wet industrial environments.

Class 1 laser design supports everyday deployment where eye-safety is required.

Optional external IMU integration supports tighter inertial navigation workflows (for example with LIO-SAM).

10-axis IMU inertial navigation modules can be added for projects that need higher-grade inertial inputs.

Up to a 120 m measuring radius helps extend obstacle detection and planning distance in outdoor scenes.

Choose 5 Hz, 10 Hz, or 20 Hz scan frequency to balance update rate, mapping detail, and computing load.

The WLR-720 LiDAR supports single-echo and dual-echo ranging with measuring point rates listed as 288,000 and 576,000 points per second.

Windows PC client software lets you view the 360° point cloud output during setup and testing.

Adjustable shielding angle settings help block unwanted scan sectors, such as the left 30°, for cleaner point cloud data during robot operation.

The WLR-720 LiDAR is commonly used for ROS robots, mapping and navigation, warehouse logistics automation, and autonomous driving research.

Yahboom WLR-720 learning resources include an online tutorial link and downloadable documents for popular SLAM algorithms like LOAM, Cartographer, A-LOAM, and LIO-SAM.

VANJEE WLR-720 LiDAR dimensions and mounting-hole layout help plan enclosure fitment and bracket placement.
