Course TF ROS2 error with the robot model

[frabbit]

Hi, hello everybody, i’ve just started the course for TF ROS2 and i have some struggle with this error:

i’ve followed the step so:
-source of the environment
-open rviz2
-select the transform and robot description
and here we are. Rviz also tell me this:

Warning: Invalid frame ID "deepmind_robot1_backl_yaw_link" passed to canTransform argument source_frame - frame doesnot exist
         at line 93 in ./src/buffer_core.cpp

etc etc etc
How can i solve it? i’ve tried to colcon build another time but nothing

Hi @frabbit, sorry for the delayed response. The warning says:

Warning: Invalid frame ID "deepmind_robot1_backl_yaw_link" passed to canTransform argument source_frame - frame doesnot exist

It seems like you have not selected a robot frame under the TF element. I can’t see it because the drop down menu isn’t clicked for it. You should select a frame that exists in the robot you are trying to visualize.
