Get a Ubuntu Snappy Core drone and access to the "app store" for drones
With the
support of Canonical, the PixHawk Fire Cape together with the BeagleBone Black will give everyone access to a
Snappy Ubuntu Core brain for making drones. This means that you'll be able to access the app store for drones we've been working on over the last months:

Start developing drone apps already ;)!
Story
![]()
The PixHawk Fire (PXF) has been evolving over the last year. It went through different versions improving capacitor values, changing functionality exposed, addressing booting issues.
The initial concept started from Philip Rowse, an Australian hardware engineer. Philip and Víctor got in touch through the BeaglePilot project which aimed to port APM to Linux. At that time Víctor was working on Erle-Board, an integrated BBB-based design for making single-PCB drones. Giving the high costs of the final design Víctor decided to jump into the PXF and push forward a single design together.
Who's behind the cape
The following organizations contributed to make the PXF and its software a reality:
Documentation
The PXF is documented in Erle-Brain GitBook. Additional sections would be added by user request and optionally a sole GitBook could be created for this cause.
Discussion about the cape is available through:
About Erle Robotics
Erle Robotics is a startup based in the Spain and led by a group of young roboticists focused on bringing up the next generation of personal Linux-based robots powered by ROS.
