TOF (Time-of-Flight) Ranging Technology

Adopting TOF (Time of Fight) ranging technology, measuring distance according to the time-of-flight of the laser pulse. The maximum ranging distance can reach up to 25m to meet the demand of most commercial applications, and can reach the measurement accuracy of ±20 mm within the effective detection distance of 8m. With efficient algorithm logic to achieve 360° detection of the robots, autonomous mapping, and obstacle detection...

Supports Start-stop Control via Software

Open source for demo, schematic diagram and other resources of the adapter board, enabling personalized development and Lidar operation control, effectively prolonging its lifetime.

More Stable Performance, Long Lasting Lifetime

Adopts Coaxial brushless motor, quiet without friction, supports high-speed wireless data transmission with stable performance. Features a longer lasting lifetime up to 10000+ hours, meets the requirement of low failure rates in the projects.

360° Omni-Directional Laser Scanning

Rotates clockwise in the ranging core to achieve 360-degree scanning and ranging of the surrounding environment, thus obtaining the contour map of the surrounding environment and the point cloud information of the location of obstacles

Ranging Radius up to 25m

 Longer Ranging Distance, Can Obtain the Environmental Information in A Farther Range, Ensuring The Large-Area Cruising And Mapping Capabilities Of the Robots

 * The ranging distance data is obtained by repeated measurements of STL27L and a target surface with 80.6% reflectivity under laboratory conditions.

High Real-time & Accurate Map Building

Supports scanning at 10Hz and measuring distance at a rate of 21600Hz, effectively reducing navigation blind spots and improving scanning coverage

Multi-echo detection technology, Supports glass wall detection

Supports glass wall detection at specific angles through multi-echo detection technology, reducing collisions during robot operation and increasing safety

Strong Ambient Light Tolerance

Adopts excellent filtering technology to meet the use in 60Klux strong light, suitable for a variety of indoor and outdoor scenarios

Exquisite, Compact, Easier to integrate

It adopts a compact structure design, smaller size, lower power consumption, and can be embedded inside the robot to reduce the overall size and improve its passability.

Laser Safety FDA Class 1

To ensure the safety for humans and pets, a low power infrared laser emitter is used as the light source and is driven by modulated pulses, the laser completes the emitting action in a very short period of time, complying with the FDA Class 1 human eye safety rating
