Version: ROS 2 Humble

Robot Operating System 2 (ROS 2) Overview

For ROS 2 Humble and beyond, the software structure of Clearpath robots has changed significantly. Rather than having individual sets of packages for each robot, we have opted to create common clearpath packages which are used by all supported platforms. Additionally, we are moving away from using environment variables to customize the robot, and instead using a YAML configuration file to describe the robot. We have also defined a ROS 2 API common to all of our supported platforms. As a result, our platforms are now more customizable, more modular, and more unified.


Clearpath Platform: The platform refers to the vehicle that makes up the base of the robot. The platform may be referred to by the platform code to indicate the revision.

Clearpath Robot: The robot refers to the entire robotic system, including the platform, sensors, and additional accessories.

Clearpath Config: The config refers to the robot.yaml configuration file that defines the Clearpath robot.

Clearpath API: The API refers to the ROS 2 application programming interface. This is a set of ROS 2 topics and services defined by Clearpath which are used by all supported Clearpath platforms.
