Hi!
I'm working on this branch, and I have some questions:
-
Is it possible to include xacro tags directly in the SDF code? I was looking but I did not find decision blocks (similar to the xacro:if) for SDF.
In ROS2 Foxy documentation I found that they can be replaced from the launch file, so I proceeded that way, processing the xacro file to get the robot description. But it would be great to replace them from the SDF. -
can
revolution joints
be used in a xacro file? In the original Dolly model, a Joint Revolute is used for the wheels. However, when I wrote the Xacro I use Continuous Joints since in this way thediff_drive plugin
can work correctly. Or is it an error with my environment?

I recently looked a bit into it and I couldn't find a way 😕 I originally thought that xacro was general enough to template any XML file but now I think it's very specific to URDF...
In this case, I think it may be possible to use SDF param passing. It's not as flexible as xacro, but it should be enough.

URDF has a revolute
joint type, but in this use case, continuous
would be more fitting. SDF uses revolute
for both types.
I've been trying to stick to SDF with Dolly because it's more flexible than URDF, but as you're seeing, there are some details still to be figured out 🙂
