Fast DDS and ROS2 power many IoT devices, including many that might already be in your home. Some examples:
iRobot Roomba & Create3:
A good example is the iRobot Roomba.
Some models use ROS2 and Fast DDS, and they even create an educational Robot similar to the large production models, the Create 3.
Micro-ROS: An eProsima open-source project.
Micro-ROS is the official extension of ROS2 for microcontrollers. It was initially a European-funded project coordinated by eProsima and is now maintained and updated constantly. Thousands of developers use Micro-ROS in their IoT projects, from hobbyist projects to professional applications.
