Checks

[ ] Check Rviz

Launch using the rviz2 command.

The rviz window should be generally usable and should be able to load some of the discovered visualizations.

Loading visualizations into the tree and using the mouse to navigate through the virtual workspace is sufficient for this test.

details
**Try** 1. ```bash # User input in terminal 1 ros2 launch dummy_robot_bringup dummy_robot_bringup.launch.py ``` 1. ```bash # User input in terminal 2 rviz2 ``` 1. In RViz, in the left pane, click 'Add'. A window will pop up. In that window, under 'rviz_default_plugins', select 'TF' and click 'OK'. Under 'Displays', in the 'Global Options' section, change the 'Fixed Frame' to '/world'. 1. In RViz, in the left pane, click 'Add'. A window will pop up. In that window, under 'rviz_default_plugins', select 'LaserScan' and click 'OK'. Under 'Displays', in the 'LaserScan' section, change the 'Topic' to '/scan'. **Expect** 1. You should see the dummy robot's kinematic tree waving back and forth in the rviz window. 1. You should see a laser scan emitting from the waving end of the dummy robot. 1. Play around, move the camera, enable and disable things in the 'Displays' pane. RViz should be stable.

Use ros2 launch dummy_robot_bringup dummy_robot_bringup_launch.py instead of ros2 launch dummy_robot_bringup dummy_robot_bringup.launch.py.

Expect

You should see the dummy robot's kinematic tree waving back and forth in the rviz window. OK
You should see a laser scan emitting from the waving end of the dummy robot. OK
Play around, move the camera, enable and disable things in the 'Displays' pane. RViz should be stable. NG

Problems

After unchecking and checking the LaserScan checkbox, the LaserScan status in the Displays becomes unstable (switch state repeatedly Error <-> Ok ). rviz2 in the console outputs error information frequently.
