When I run roslaunch quad_utils quad_visualization.launch, the RViz interface is blank. However, when I run gazebo.launch, the robot model is displayed correctly, and other programs also work fine. Below is a video of this operation

Hi @nanbwrn, Thats to be expected. The launch file quad_gazebo.launch runs the entire stack (except for planning), so it launches the rviz interface, loads in the robot and launches robot driver etc.

Quad_visualization.launch only runs the rviz visualization plugins for the robot, so it doesn't run the rest of the stack. Typically, quad_visualization is used if you want to run visualize a recorded bag file.

See an example here: https://github.com/robomechanics/quad-sdk/wiki/3.-Processing-Data-Logs

Best, David
