What to do if RoboSense Robotics LiDAR rotates but there is no data output?
- A
  Anne WatsonAug 16, 2025
  If your RoboSense Robotics LiDAR is rotating but not outputting data, try the following: * Ensure the network connection is stable. * Verify that your computer's network configuration is correct. * Use software like Wireshark to check if the packet output is normal. * Disable firewalls and security software that might be blocking the network. * Confirm the power supply is working correctly. * Restart the sensor.

Why am I experiencing frequent data dropouts with my RoboSense Robotics LiDAR?
- J
  Jessica HernandezAug 18, 2025
  Frequent data dropouts with your RoboSense Robotics LiDAR might be due to: * Excessive network traffic or collisions. * Other network devices sending too many broadcast packets, slowing down the sensor. * The computer or interfaces not being fast enough to handle the packet flow. To troubleshoot, try removing other network devices and connecting the sensor directly to the computer to see if the packet loss stops.

How to fix the issue when I can see data in Wireshark but no point cloud in RoboSense Robotics RSVIEW?
- J
  Jean JonesAug 25, 2025
  If you see data in Wireshark but no point cloud in RSVIEW, try these solutions: * Disable the computer firewall and allow RSVIEW to bypass it. * Ensure the computer's IP address matches the LiDAR's IP address. * Verify that the Data Port setting in RSVIEW is correct. * Confirm that the RSVIEW installation directory and configuration file storage directory only contain English characters.

How to troubleshoot RoboSense Robotics GPS/PTP synchronization issues?
- T
  Teresa KhanAug 28, 2025
  To troubleshoot GPS/PTP synchronization issues with your RoboSense Robotics system, ensure the following: * The synchronization mode is correctly set on the web page. * The GPS baud rate is 9600bps and serial port is set to 8N1. * The GPS signal level is 3.3V TTL or RS232. * The 1PPS pulse is continuous and correctly connected. * The GPRMC message of NMEA is correct. * The GPS and Interface Box share the same ground. * The GPS has received a valid message. * The GPS module is outdoors. * The PTP Master synchronization protocol complies with the current PTP protocol. * The PTP Master is working properly.

What to do if there is no data output when RoboSense Robotics sensor is connected to a router?
- C
  Carrie PerrySep 2, 2025
  If you experience no data output when the sensor is connected to a router, turn off the DHCP function of the router or set the IP address of the sensor to the correct IP address within the router's network.

Why does RoboSense Robotics RSVIEW software output the point cloud into a ray?
- J
  John JohnstonSep 8, 2025
  If you are using a Windows 10 system, set RSVIEW to run in Windows 7 compatibility mode.

Why is there a fixed blank area that continuously rotates in the RoboSense Robotics point cloud?
- R
  Robert BurtonSep 12, 2025
  This is normal behavior. The ROS driver performs frame display according to a fixed number of packets, and the blank part of the data will be displayed in the next frame.
