 From the level of ROS onwards, we strive to re-use as much as possible from ROS 2, and be as compatible with it as possible. In some areas, we will probably do custom implementations optimized for resource use. This will definitely include TF, and maybe other areas such as scheduling. These optimized implementations may also be interesting for use with "normal" ROS2.
 
 We'll update this README as we proceed. For now, you can check out our work on:

 ### Architecture
 The micro-ROS architecture is a work in progress. It's modular and built with the following ingredients:
