custom-interfaces

Use a dedicated _interfaces package, such as my_robot_interfaces, to isolate .msg, .srv, and .action definitions. This structure prevents circular dependencies and ensures interface packages remain standalone and reusable across ROS 2 projects.

ROS 2 interface naming conventions require consistent prefixes and clear descriptive names for .msg, .srv, and .action files. Following standard naming conventions ensures interfaces scale with your project and prevents integration gaps across Jazzy and Rolling distributions.

Configure CMakeLists.txt and package.xml with appropriate dependencies to make ROS 2 interface packages standalone. Step-by-step package setup guidelines ensure your .msg, .srv, and .action files build correctly and remain reusable across Jazzy and Rolling distributions.

Yes, the interface design guidance applies to ROS 2 workflows across both Jazzy and Rolling distributions. It covers package layout, naming conventions, and build configuration to prevent integration gaps from initial setup through final deployment.

You need a dedicated _interfaces package in ROS 2 when defining custom .msg, .srv, or .action files for a project. Isolating interfaces prevents circular dependencies, ensures standalone reusability, and maintains consistent naming conventions as the project scales.

The best way to design scalable ROS 2 services and actions is to define them in a dedicated _interfaces package following standard naming conventions. Real-world use cases demonstrate how to structure .srv and .action files to prevent integration gaps across Jazzy and Rolling.
