 ## Architecture
 
-We're basically following the ROS2 architecture and make use of its middleware pluggability to use DDS-XRCE, which is suitable for micro-controllers. Moreover, we use an RTOS (NuttX) instead of Linux. On micro-controllers many different RTOS's are used, so we also add an RTOS abstraction layer (AL), to make porting to other RTOS possible.
