[Rock-dev] [Rock-users] Problems to get ROS-Rock working in all branches (Ubuntu 12.04)

Wed Aug 27 09:44:16 CEST 2014

Hi Mathias,

Actually, I never used rock-display to see the ros part, I tested that 
stuff using the ros tooling. Also I used an extra ruby script to get 
(not start) running task contexts and connected them there (or called 
publish_to_ros on the ports I wanted to have in ROS)

It could be possible that the issue is not the bridge itself, but 
rock-display support for ros datatypes.

Can you test whether publish_to_ros works? (in a script and use ross 
tooling to see the data)

I think so, but the error was my mistake but the rock/ros directory was 
never meant to be used in first place when writing rock.ros in the 
autoproj/manifest file.

The ros package support may be considered late alpha phase, not more. It 
was just convenient in a project where we used the bridge, but there are 
sill some things that can be done better.

Kind regards,

Steffen
