Hello, I have a problem with RTDE communication not working between host with simulator and another device on the same network. About 2 months ago everything was working fine, but last week when I was about to do some test I was not able to connect to the RTDE controller.
I am also using primary / secondary interfaces, which both work fine. Some technical info:
-
sb_release -a gives:
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04 LTS Release: 14.04 Codename: trusty
-
Using VirtualBox 6.1.30
- tried with bridged connection → could not connect
- tried with bridge + NAT (with port forwarding to 30004) → could not connect
-
URSim UR3, 5, 10, 16 all fail
Tried to run script from (GitHub - ryanpennings/RTDE_UR: Real Time Data Exchange streaming for universal robots. (Streams points to robot, for running large files)):
python ringBufferUR.py --host 192.168.20.101
Universal Robots - (semi) Real Time Point Streaming ring buffer
