Topics

Work with Specialized ROS Messages

Some commonly used ROS messages store data in a format that requires some transformation before it can be used for further processing.

Work with Velodyne ROS Messages

Velodyne ROS messages store data in a format that requires some interpretation before it can be used for further processing.
