2022年9月12日 · ros2 run tf2_tools view_frames.py I got the following error: "No executable found". The tf2_tools pkg is installed with: sudo apt-get install ros-humble-turtle-tf2-py ros-foxy-tf2-tools I also installed transforms3d: pip3 install transforms3d I have the turtle_tf2_py and the turtle_tf2_demo.py running. The teleop_key is working fine.

2017年10月22日 · tf2::fromMsg is a templated function so it is not expected to be in the libraries and found by the linker, you need to make sure to have the correct include is available.

Here it is my launch file, where I launch the robot state publisher to publish the tf2 transforms, and the joint state broadcaster to broadcast the joints position through the /joint states topic, needed by the robot state publisher:

2022年3月25日 · Hello all, My robot base node, which publish odom to base link tf on /tf topic and meanwhile publish /odom topic. ros2 topic hz /odom is 50hz, consistent with my config param rate=50hz. But `ros2 run tf2 ros tf2 monitor odom base link` gives about 154 hz, i don't figure out why it is not 50 hz? RESULTS: for odom to base_link Chain is: odom -> base_link Net delay avg = 0.00471396: max = 0. ...

Sorry for my late reply and thanks for answering me! Does ros-blessed work for ROS2? I installed it, but it asked me to source the environment even after I had done it. The only debug I could make was using tf2_echo. Please, let me know any tool for debugging TF in ROS2! I just updated the question with new info. Thanks!!

2020年11月2日 · A tf2_ros::TransformBroadcaster is broadcasting the transforms between the "world" and "Frame1". So, how does the transform method work? Does it automatically assume that the streamed position messages are with respect to the "world" and performs the necessary calculation based on this assumption?

2020年5月2日 · This is the package I assume the above comments are talking about. Geometry2 contains tf2 and many other tf related packages. The problem is the order of operations. Before ever calling catkin_make, be sure to first remove the geometry2 package and be sure you have it installed as a rospkg sudo apt install ros-noetic-geometry2.

I'm following ideas from python broadcaster, listener tutorials on tf2 package. I broadcast some simple transformation in one node and listen for it in other node. However the listener node doesn't get correct transformation values. When I rostopic echo in terminal /tf topic, I see the values I've sent. Please help me why I receive wrong data?

But the code for matrix inverse does not assume the matrix is orthogonal, and the Jacobi method for diagonalizing matrices only applies to symmetric matrices, and matrices that are both symmetric and orthogonal are rather specialized. Has anyone considered representing transforms by dual quaternions? Or at least adding dual quaternions to tf2?
