Typical quadrotor aerial robots used in research weigh< 3kg and carry payloads measured
in hundreds of grams. Several obstacles in design and control must be overcome to cater for …

We describe a new configuration of fixed-pitch miniature robot rotorcraft that combines the
energetic efficiency of a helicopter and the mechanical simplicity of a quadrotor. The large …

This paper presents a novel control algorithm to regulate the aerodynamic thrust produced
by fixed-pitch rotors commonly used on small-scale electrically powered multirotor aerial …

In this report, we present the theory on aerodynamics of quadrotors using the well
established momentum and blade element theories. From a robotics perspective, the …

THIS paper introduces a class of nonplanar rotary-wing vehicle in which both the vehicle
thrust and torque vectors can be arbitrarily orientated with respect to the vehicle body axes …

The small rotor sizes of quadrotors and multirotors makes them intrinsically less energy
efficient than a traditional helicopter with a large single rotor. However, the quadrotor …

Small unmanned aerial vehicles (UAVs) come in many types, the most common being fixed-
wing and rotorcraft. Most of these are powered by brushless dc motors driving fixed-pitch …

Virtually all quadrotors used in research weigh less than 2 kg, and carry payload measured
in hundreds of grams. To be useful platforms for expanded operations, these vehicles must …

Quadrotors are aerial vehicles with a four motor-rotor assembly for generating lift and
controllability. Their light weight, ease of design and simple dynamics have increased their …

The control design for a propeller-based thrust generator used in a wind turbine testing
platform is studied in this work. A mathematical model has been developed for the system …
