Do we actually need any of this? We aren't using bullet directly in this package, and hence all of this should be inherited from tf2_bullet. If it is not, then that seems like a bug in the tf2_bullet package.

Yes, there seems to be a bug. #428 opened

Add needed includes for these at the top:
#include <tf2/LinearMath/Quaternion.h>
#include <Eigen/Eigen>
Also, I think we need to declare a dependency on eigen in the package.xml and the CMakeLists.txt.

Remove this dead code.

Add the include for geometry_msgs::msg::Vector3 at the top of the file.
Also, style nit: there should be a space before and after the reference symbol (&). We aren't enforcing it in this package yet (and I don't think we should in this PR), but we may as well make one less thing we have to change later.
The same comment goes several other times below.

I hope I addressed all of the remarks. There seems to be a blocking issue with bullet dependencies, see #428. |

Vectors can be converted to a Vector message or a Point Message, some libraries behave differently. This unit test will make sure that the default return value for
toMsg()will stay the same.This was separated from #368.
