Driver does not build on Melodic due to "SetPayload" service

[stefanz-tri]

It seems like the driver does not build on melodic (and kinetic) currently because of #50 . When using the universal_robot metapackage, the "SetPayload" service is missing the "center_of_gravity" member. When using the standalone ur_msgs package, it does not build because the "payload" member was renamed to "mass". Or is this already solved in a branch?

Did you use my fork of the universal_robot repository, as explained in the README?

[stefanz-tri]

No I actually used the main repository. It is a bit confusing that now three versions of ur_msgs exist. But that should solve the issue, thanks.

I am facing the same issue and could not figure out which fork I must use for Melodic??

The current version of the ur_msg repository has a variable name Mass
https://github.com/ros-industrial/ur_msgs

And the hardware interfaces file in
https://github.com/UniversalRobots/Universal_Robots_ROS_Driver/tree/master

is still using payload as variable

Following README file but still got errors:

What's wrong? @fmauch

Thanks

I only followed the instructions
and build successfully.

I think my previous trouble was caused in universal_robotTutorials
sudo apt-get install ros-kinetic-universal-robots

@suc1 please do not hijack an old (and closed) issue for your problems. You can link to related issues, by simply writing #235 inside the issue.

Before you open a new issue: Please note that ros kinetic is no longer supported. As mentioned in #235 (comment) this was solved.
