3 Computers Setting with ROS : Wifi -> (Wifi-Ethernet) -> Ethernet
I have a mobile robot with a wifi router plugged to it. And a workstation with no wifi. I also have a laptop with both Ethernet and wifi. I connect the laptop by Wifi to the robot, and to the Ethernet network by cable. The workstation is on that Ethernet network as well. After setting up ssh I could connect from my workstation directly to the robot and to the laptop as well. The problem is I can't run any GUI through ssh on an XServer (RViz especially) because of my Laptop having OpenGL 1.4 (It is weird because I can run RViz on the laptop directly). Even setting LIBGL_ALWAYS_SOFTWARE to 1 doesn't help and it keeps repeating the same error message:
libGL error: failed to load driver: swrast terminate called after throwing an instance of 'std::runtime_error'
what(): Your graphics driver does not support OpenGL 2.1. Please enable software rendering before running RViz (e.g. type 'export LIBGL_ALWAYS_SOFTWARE=1').
So my question is : is there a way to make some kind of bridge, so that I get an IP adress I can set on my workstation as URI Master which will automatically search for a ROS master on the robot's computer but going through the laptop?
I know that the easiest alternative would be to buy a Wifi dongle, but I am interested to know if what I described is possible.
