2020-08-27 06:44:33 -0500 | marked best answer | ros2 import tf2_geometry_msgs Hello there, I am unable to import tf2_geometry_msgs as an python3 module in ros2 eloquent. Only tf2_ros, tf2_py and tf2_msgs seem to be a python module. I am porting an melodic project to eloquent and we used the comfortable do_transform_vector3 function of that script. Someone else seems to have a similar issue with c++: link (Maybe its completely unrelated though) Am I missing something here? |

2019-03-28 03:06:08 -0500 | marked best answer | Ros 2 import tf2 Python Hello, I started having a look at Ros 2 (crystal) two weeks ago and really had a hard time creating a package that produces some executables.
As I managed to do that I tried to migrate some old code to Ros 2 code. It was just a tiny project which moved a frame in a circel around the world-frame's center in rviz. To do that I used the TransformBroadcaster imported from tf. I saw that there is now tf2 in my rosdistro/share, so I tried to import that with The weird thing is, I can import TFMessage from tf2_msgs and publish TFMessages to tf 'by hand'. This really feels like I overlooked something trivial but as I didn't find anything so far I wanted to ask here. |
