You're reading the documentation for a version of ROS 2 that has reached its EOL (end-of-life), and is no longer officially supported. If you want up-to-date information, please have a look at Jazzy.
joint_state_controller
The joint_state_controller
has been renamed to joint_state_broadcaster
in order to differentiate between true controllers and simple data broadcasters.
This package will be removed in ROS H-Turtle. Instead, use package
joint_state_broadcaster
.
