Hi Dominus
Current focus is SLAM and then improving of perpherals (mostly audio nodes)/motors. So far we dont have exact roadmap as we are facing one significant blocker but when we get that sorted, we will probably be able to give pretty decent estimates when new functionalities will be out.
there will be additional functionality in web form - expanding the existing RAE - Default app with map (SLAM) and navigation (go to point on map)
which we plan to open source to guide users on how to develop their own apps
FW update is one-click install from RH platform. The reason you are not seeing any pending updates is because there are none at the moment. Latest FW to my knowledge is 1.12.
As for storage upgrades, AFAIK it is not possible to upgrade it at this time.
It is possible to control each LED separately in ROS directly - granted idk how useful that is to users who are not advanced ones. Future apps will generally involve LEDs as sending a message (like taking a turn, close to the wall,...).
EDIT: additional info
Thanks,
Jaka
