Creating Packages in ROS 2
Package Fundamentals
A package serves as a container for organizing ROS 2 code. When distributing or sharing your software, code must be structured within packages. This organization enables others to easily build and utilize your ROS 2 projects.
ROS 2 packages utilize ament as their build system and colcon as the build tool. Packages can be cr ...

ROS 2 Communication Patterns: Parameters and Actions
Parameters: Dynamic Node Configuration
Parameters are key-value pairs used to configure node behavior at runtime. Each parameter consists of a string name and a value of supported types: bool, int64, float64, string, or byte. Unlike topics or services, parameters are not used for data exchange but for tuning node settings dynamically. To inspec ...

Mastering ROS 2 Topic-Based Inter-Process Communication
Core Concept: The Topic Abstraction
In robotic software architectures, individual nodes handle distinct responsibilities such as perception, planning, or actuation. These components rarely operate in isolation; they rely on robust communication channels to exchange state and commands. Within the Robot Operating System 2 (ROS 2) ecosystem, topic ...
