Common Problem
Subclass：
Answer：Interference between multiple LiDAR sensors can be mitigated or even avoided by adding PhaseLock function to the LiDAR or optimizing the LiDAR mounting position.
Answer：Yes. The time synchronization board is sold as part of RoboSense’s LiDAR perception solutions. Please check with your account manager for a quotation.
Answer：RoboSense LiDAR sensors are certificated with class 1 eye safety according to the IEC/EN 60825-1:2014 standard, which means they are safe under all conditions of normal use.
Answer：Currently, this problem only presents in the RS-LiDAR-16, RS-LiDAR-32 and RS-BPearl products. Other products do not have such problem.
（1）When the time mode of the RS-LiDAR-16, RS-LiDAR-32, and RS-BPearl is 255 or 0 (Check through RSVIEW-TOOLS-RSLidar info), there will be a lag of 1S+1 PPS pulse width;
（2）When the time mode of the RS-LiDAR-16, RS-LiDAR-32, and RS-BPearl is 1, there will be a lag of 1S;
（3）When the time mode of the RS-LiDAR-16, RS-LiDAR-32, and RS-BPearl is 2, the time is synchronized with the current time of GPRMC;
（4）The V3.0 and earlier version of the RS-LiDAR-16, and the V1.7 and earlier version of the RS-Lidar-32 do not support time mode setting;
Answer：Not at the moment. If necessary, please contact RoboSense technical expert to evaluate the feasibility and cost.
Answer：No.
Answer：
(1) The power supply should be stable;
(2) The power supply and current should be able to support stable operation of the LiDAR;
(3) The power supply shall provide sufficient starting current for the LiDAR;
Answer：The LiDAR sensor itself is waterproof, but the interface box is not.
Answer：Check the current and voltage output. If you are using modified or extended cable, please also check the voltage drop.
Answer：The connect of RS-LiDAR-16 before v4.0 and that of the RS-LiDAR-32 before v2.0 are not waterproof.
Answer：The rotating point cloud is due to repeated restart of the LiDAR. If the screw is too tight or the mounting platform is not flat, the stressed will change the ideal space between the code disc and the encoder in the LiDAR, resulting in the zero point cannot be recognized and therefore the repeated restart of the LiDAR.
Answer：This might be due to a host computer that loses packets. Please check the host computer CPU and memory occupancy, or the network load and network status.
Answer：For LiDAR sensors using lasers of the same wavelength and without anti-interference function, there will be noise in the point cloud. Mechanical LiDAR with PhaseLock function can effectively avoid interference without affecting the quality of point cloud.
Answer：This is a normal phenomenon. Framing is done at a fixed-angle, when there is a sharp turn or an emergency braking, the framing angle will fluctuate (the angle of a UDP packet), visually, there will be gaps or overlaps of point cloud at the framing angle, nevertheless, the point cloud data is not lost.
Answer：905nm.
