ROS Network Connection and Exploration

Set up and interact with ROS networks

Connect to ROS 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 network. To set up a ROS network, start by calling rosinit.

You can access transformations between coordinate systems as ROS topics and use them to transform data in MATLAB. For more information, see Access the tf Transformation Tree in ROS.

The rosrate object helps control the timing of code execution.
