Common interfaces is a metapackage (collection of packages) that includes the standard set of messages (.msg) and services (.srv) available on all ROS systems.

The following packages are contained in the common_interfaces meta package. The links below point to Rolling Ridley API documentation for each package.

• diagnostic_msgs
• geometry_msgs
• nav_msgs
• sensor_msgs
• sensor_msgs_py
• shape_msgs
• std_msgs
• std_srvs
• stereo_msgs
• trajectory_msgs
• visualization_msgs

Isolating the messages to communicate between stacks in a shared dependency allows nodes in dependent stacks to communicate without requiring dependencies upon each other. This repository has been designed to contain the most common messages used between multiple packages to provide a shared dependency which will eliminate a problematic circular dependency.
