Multiple sick tim 561 with the same ip address have mismatched data #38

Closed CaptD closed 5 years ago

CaptD commented 5 years ago

Hi, I have nine sick tim 561 on nine mobile robots, one on each. At first, I configured all these nine lidars with the same IP address 192.168.1.1 with SOPAS, so I can have the same launch file for all these nine robots. However, when I started these nine robots, I found lidar #1 detected points obviously from another lidar #2. And this happened for all lidars.

Is it because of my mis-configuration, or is it common sense to avoid the same local ip address for sick tim lidars under one router?

Thanks.

You must configure each scanner with its own ip address. E.g. 192.168.1.1 for the first, 192.168.1.2 for the second and so on. Then you must setup a launch file similiar to an extended version of https://github.com/SICKAG/sick_scan/blob/master/launch/sick_tim_5xx_twin.launch

Also you can use the tool "https://github.com/SICKAG/sick_scan/blob/master/tools/sick_generic_device_finder/sick_generic_device_finder.py" to check your scanner setup.
