Traditionally, ROS has stopped at the microcontroller boundary, even though robots contain many of them. Usually, they are integrated through serial protocols. This is error-prone work and worse, many existing sensors and actuators have proprietary firmware that cannot be changed, because manufacturers are concerned (not unreasonably so) that user-changes might break it. Therefore, the micro-ROS project is working on bringing full microcontroller support to the ROS 2 ecosystem, and to provide safe mechanisms for composability. In this talk, we will introduce current work, our architectural approach, the hardware we support, challenges we addressed, and challenges that remain.
