n the part where I should see the robot in RVIZ, I can’t add the “robot_description” and “tf” fields because I don’t have the “add” option in the lower left field and I couldn’t find any other way to do it.
A different message also appears in the shell when I execute the command for RVIZ:
“process[robot_state_publisher-2]: started with pid 
[WARN] [1609699272.588294, 3900.595000]: The ‘use_gui’ parameter was specified, which is deprecated. We’ll attempt to find and run the GUI, but if this fails you should install the ‘joint_state_publisher_gui’ package instead and run that. This backwards compatibility option willbe removed in Noetic.”
What do I do?
