From the DroneLab at the University of California in San Diego:
BeagleMAV
BeagleMAV is a 3D-printed hexacopter that derives its extremely low weight of 500 grams (1.1 pounds) from its unique monocoque structure that was designed iteratively with modal finite element analysis. The monocoque frame design emphasizes simplicity of assembly and safety of indoor flight.
With the BeagleBone Black and Robotics cape at its heart structurally and electrically, the drone’s flight controller is based on the same software environment used for most DroneLab robotics projects (to maintain interoperability). Since the control system is based on a Linux operating system, it becomes possible to connect the BeagleMAV with a wide range of sensors and network interfaces — with minimal modification.
