LiDAR, also known as Light Detection and Ranging, is a system that combines laser, Global Positioning System (GPS), and Inertial Navigation System (INS) technologies to acquire data and generate accurate digital elevation models (DEMs). This combination of technologies allows for precise positioning of the laser beam’s spot on the target with centimeter-level ranging accuracy. The biggest advantages of LiDAR are its high accuracy and speed. In the field of robotics and autonomous driving systems, the most acclaimed LiDAR in the past two years has been the LiDAR used for autonomous navigation in self-driving vehicles. Notably, it helps drones and autonomous vehicles avoid obstacles independently, making it a crucial core sensing component for navigation, positioning, and obstacle avoidance.

The laser transmitter emits laser pulses. When the laser strikes the target, some of the light is reflected back to the laser receiver. By calculating the time difference between the emitted and received pulses, the distance can be calculated. The laser transmitter continuously emits laser pulses, which are distributed at a certain angular interval (i.e., angular resolution) through a rotating optical mechanism, thus forming a two-dimensional scanning surface.

Distance = Speed ​​of light × (t2 – t1)/2

(1) The power supply should be stable;
(2) The power supply and current should be sufficient to support the stable operation of the lidar;
(3) The power supply should provide sufficient starting current for the lidar.

RoboSense LiDAR sensors have passed the IEC/EN 60825-1:2014 Class 1 eye safety certification, meaning they are safe under all conditions of normal use.

By adding phase-locking capabilities to the LiDAR system or optimizing the installation position of the LiDAR sensors, interference between multiple LiDAR sensors can be mitigated or even avoided.

Yes. The time synchronization board is part of the RoboSense LiDAR perception solution. Please contact your account manager for a quote.

Currently, this issue only exists in RS-LiDAR-16, RS-LiDAR-32, and RS-BPearl products; other products are not affected.
(1) When the time mode of RS-LiDAR-16, RS-LiDAR-32, and RS-BPearl is 255 or 0 (which can be checked via RSVIEW-TOOLS-RSLidar info), there will be a delay of 1 second + 1 PPS pulse width;
(2) When the time mode of RS-LiDAR-16, RS-LiDAR-32, and RS-BPearl is 1, there will be a delay of 1 second;
(3) When the time mode of RS-LiDAR-16, RS-LiDAR-32, and RS-BPearl is 2, the time is synchronized with the current time of GPRMC.
(4) RS-LiDAR-16 V3.0 and earlier versions, and RS-LiDAR-32 V1.7 and earlier versions do not support time mode settings;

Answer: No.

A: The lidar sensor itself is waterproof, but the interface box is not.
