ROS 2 Network Connection and Exploration

Set up and interact with ROS 2 Networks

Connect to ROS 2 to prototype robotics applications and access robotics hardware or simulators over a ROS network. You can create your own ROS network using MATLAB® or connect to an existing ROS 2 network. To set up a ROS 2 network, create a ROS 2 node using ros2node object.

You can access ROS 2 parameters using ros2param object and its object functions.

The ros2rate object helps control the timing of code execution.
