Hi,
I’m trying to run the ursim_cb3 docker image on my windows 11 laptop with docker desktop but I’m unable to get it working.
When I start the container with the following parameters the java application fails to get a connection to the controller.
docker run --rm -p 5900:5900 -p 6080:6080 --name ursim_cb3 universalrobots/ursim_cb3
In Initialization screen it first says disconnected from controller. I can press restart. Afterwards it just shows “NO CONTROLLER” and the button changes to “Start”.
I was able to run the script below to get the simulator running showing “Normal” state, but I was not able to move the robot. Seems in the urcontrol log that there is some problem with a TCP connection.
docker exec -it ursim_cb3 bash -c 'cd /ursim/ && ./stopurcontrol.sh && ./starturcontrol.sh'
Found the image here:
https://hub.docker.com/r/universalrobots/ursim_cb3
The e-series version seems to work fine.

For information I tested it from my ubuntu machine and experienced no issues.
I’ve encounter the no controller issue before using the e-series simulators on Windows11.
I resolved the issue by updating Docker Desktop; it was behind a patch number causing the issue.
Thanks for chiming in. Actually I just got the no controller issue myself of e-series on Windows 11.
Manually trying to start URControl gives the following issue:

URControl::shutdown
Afraid I can’t be too much help here. I also observe the no controller issue when starting the cb3 container. I also observe a similar output when launching URControl.
docker run --rm -it -e ROBOT_MODEL=UR10 -p 5900:5900 -p 6080:6080 universalrobots/ursim_cb3
