Mini Autonomous Flying Vehicle
•CASDE is part of the National effort to develop a Micro Air Vehicle.
•CASDE has chosen a Mini Vehicle, in the short term, keeping in mind the autonomous mission.
•CASDE feels that ~500 Gms. of Avionics is bare minimum to make a mission autonomous.
•A 2 Kg. Aircraft, with 500-600 Gms. payload, needs to be demonstrated.
