Add support for 10kg and 12kg variants of GoFa robots (abb_crb15000_support) #202

There are two more models on the GoFa product line for 10kg and 12kg payloads. It would be great to add support for them to this package. Is there a source from which we could get a hold of the URDF and meshes of those models? If so, I can prepare the PR to add it to this repo.

The model I added in ros-industrial/abb_experimental#127 was based on a conversion from the CAD made available by ABB on their website.

If the variants you mention do not have any geometrical differences, you'd only have to add a new xacro:macro, reusing the original meshes, but (I assume) updated joint limits.

Thanks! I started updating the URDF you provided also converting from the CAD models.

The 3 GoFa models have geometrical differences (mainly links 2,3,4 have different lengths), so the meshes should be updated.
How did you find joint limit values? Also from ABB data sheet?

EDIT: links 1,2,4 + base have different sizes

Please make sure to reuse meshes as much as possible. If only those links changed, reuse the existing meshes for the other links.

yes, that'd be a reliable source of information, although in case of asymmetric limits, you'll either need to check them against a real robot, or RobotStudio.

(technically you could also use RWS to get the info, as abb_robot_driver does, but that's probably more work)
