hi,
when I use below code:

    <node pkg="robot_state_publisher" type="robot_state_publisher" name="robot_state_publisher" output="screen">
      <param name="publish_frequency" type="double" value="50.0" />
      <param name="tf_prefix" value="tb3_1_tf" />
    </node>

The tf tree of the robots is fine in contrast to using the frame_prefix parameter.
The ROS version is Noetic and rviz version is 1.14.14, all executed in Ubuntu focal.

Sorry, I'm not sure what you mean. In ROS 1 noetic, using tf_prefix is the correct way to add prefixes to TF. frame_prefix is new in ROS 2, so doesn't apply to ROS 1. Can you explain more about what you are expecting to happen?

I was trying to apply frame_prefix to ROS1.
Sorry for my mistake.

OK, thanks. Closing this out, then.
