 ### Known issues
 - When using the default ros 2 middleware rmw_fastrtps_cpp the may get unresponsive sporadically if you very often subscribe and unsubscribe to the image_raw topic. This happens due to a deadlock in the middleware implementation. Therefore it is recommended to use rmw_cyclonedds_cpp as ros 2 middleware instead.
