This is compiling but has not been tested. I'm opening the PR for visibility as I'll be on vacation next week.

There are a few TODOs to check and adding some unit tests would be really good.

This builds on top of #803 as well.

I finished most of the port and started the migration guide. Also:

  • Added a demo world with instructions
  • Added a test that commands are received and odom is published
  • The test doesn't check TF

When visualizing TF on RViz, note that due to ros2/rviz#332 the wheels are not updating correctly, but the TF is being properly published:

tf_diff_drive


@tfoote , I haven't addressed the QoS comments you left. If you don't have time for it once you're back, I can take a stab at it.

Motivated by this PR, I also started a migration guide for gazebo_ros_utils, more specifically the get* functions.

After talking to @tfoote , we will merge this PR and retarget #815 to ros2
