+*   [EU project OFERA](http://ofera.eu/): The EU project OFERA (Open Framework for Embedded Robot Applications) aims at a ROS 2-compatible stack for MCUs in the range of STM32F4 or STM32L1, i.e. with possibly less than 100kB RAM. The project partners currently investigate of using the ROS 2 rmw, rcl and rclcpp layers as-is on the micro-XRCE-DDS implementation of the upcoming XRCE-DDS standard. In parallel, a more modular approach in the style of rosserial is investigated. In the project's use-cases, NuttX is considered as primary choice for the RTOS. Beyond the project page, additional details of the project results can be found at [http://micro-ros.com](http://micro-ros.com).
