ROS Bridge sample without external hardware devices (no camera required)

Since I don’t have the V4L2Camera used in the ROS Bridge sample, I have written a fake ROS publisher as the camera and provide the code here: GitHub - j3soon/isaac-sdk-extended: Provide some Isaac SDK examples and notes not included in the toolkit.

After writing the sample above that does not require any camera, I make it work on a Zed camera: GitHub - j3soon/isaac-sdk-extended: Provide some Isaac SDK examples and notes not included in the toolkit.

Just posting the code here in case someone want to try out a minimal sample for ROS bridge.
