Answer：The rs_SDK is dependent on the ros system because it relies on visualization tools like rviz. The rs_driver is independent of the ros system.
Regarding Lidar
Answer：Check the rs driver tutorial at github. For compilation errors, please check whether the relevant dependencies are installed. https://github.com/RoboSense-LiDAR/rs_driver
Answer：RS LiDAR only supports saving data in pcap format.
Answer：RS LiDAR only supports saving data in pcap format.
Answer：The unit is meter.
Answer: After changing the PC IP, you need to cut the LiDAR connection and reconnect;
After unplug the LiDAR, you need to examine the connection of the LiDAR;
Check if the ports are configured correctly;
Answer：First of all, please make sure that you are using the right RSView version for your LiDAR. RSView for different RoboSense LiDAR products can be find on RoboSense website. For Windows users, please check the PC IP setting, RSView port setting and the firewall status of your computer. Please make sure that your PC IP is the destination IP of the LiDAR, and the RSView MSOP port is the LiDAR MSOP Port. After which, please check if the firewall on your computer permits the operation of the RSView, if not, please turn off the firewall. If there is still no point cloud display, set the administrator authority for the RSView and set the RSView to be compatible with Windows7, then run as administrator. B. If you are using Ubuntu, please make sure that your PC IP and the MSPO and DIFOP of the RSView are set correctly.
Answer：You can download RSView from RoboSense official website or you can ask your account manager for it. https://www.robosense.ai/en/resources Currently, there are only RSView for Windows and Ubutu. RSView is compatible with Windows 10 and Ubuntu 16.04.
Answer：Due that the RSView does not support display of point cloud of multiple LiDAR sensors at the moment, we suggest you use the rs driver to view the point cloud of multiple LiDAR sensors. If you need support, please contact a RoboSense technical expert.
Answer：(1) Configure the host computer IP to the destination IP of LiDAR to send UDP packets. (2) Connect LiDAR to Interface Box through the LiDAR data cable; (3) Connect the power supply adaptor to the Interface Box to supply 220V AC power to the LiDAR; (4) Connect the Interface Box to the host computer with the network cable.
Answer：Yes, please provide 100Base conversion port for RS-LiDAR-16, RS-LiDAR-32, RS-BPearl and RS-Helios, and 1000Base conversion port for RS-Ruby, RS-Ruby-Lite and RS-LiDAR-M1.
Answer：All RoboSense LiDAR products support multicast mode.
Answer：You can find the download address at github: https://github.com/RoboSense-LiDAR
Answer：Please ensure the connectivity of LiDAR, and point cloud can be displayed and get the firmware information in RSView.
Click Tools -> Online Update, as shown in Figure 1, top board update and bottom board
update could be selected.
Click Top Board Update, then choose the proper firmware file with suffix “.bit”, then click
open, start Top Board Update. The update process will take a while, after update “Online
Update Successful” will be shown in a message box.
Note: Config Updata is not available
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：Currently, this problem only presents in the RS-LiDAR-16, RS-LiDAR-32 and RS-BPearl products. Other products do not have such problem.
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; When the time mode of the RS-LiDAR-16, RS-LiDAR-32, and RS-BPearl is 1, there will be a lag of 1S; 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; 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：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：
(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：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：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.
