Underactuated Rotor for Simple Micro Air Vehicles
Underactuated Rotor for Simple Micro Air Vehicles

We extract thrust, roll, and pitch authority from a single propeller and single motor through an underactuated mechanism embedded in the rotor itself. This allows new types of conventionally-capable micro air vehicles now requiring only two motors. This contrasts with the servos and linkages of conventional helicopters or the four drive motors in quadrotors.
