Basically, as lab frame or reference frame, there are two kinds of conventions for the frames: East, North, Up (ENU), used in geography; North, East, Down (NED), used specially in aerospace; This frame referenced w.r.t. Global Reference frames like Earth Center Earth Fixed (ECEF) non-inertial system.
A quadcopter, also called quadrocopter, or quadrotor [1] is a type of helicopter or multicopter that has four rotors. [ 2 ] Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern unmanned aerial vehicle or drone.
In many flight dynamics applications, the Earth frame is assumed to be inertial with a flat x E,y E-plane, though the Earth frame can also be considered a spherical coordinate system with origin at the center of the Earth. The other two reference frames are body-fixed, with origins moving along with the aircraft, typically at the center of gravity.
The axes of the original frame are denoted as x, y, z and the axes of the rotated frame as X, Y, Z.The geometrical definition (sometimes referred to as static) begins by defining the line of nodes (N) as the intersection of the planes xy and XY (it can also be defined as the common perpendicular to the axes z and Z and then written as the vector product N = z × Z).
DJI Phantom 1 drone. A multirotor [1] or multicopter is a rotorcraft with more than two lift-generating rotors.An advantage of multirotor aircraft is the simpler rotor mechanics required for flight control.
The flexibility allows for support of a wide variety of frame types and sizes, different sensors, camera gimbals and RC transmitters depending on the operator's preferences. ArduPilot has been successfully integrated into many airplanes such as the Bixler 2.0. The customizability and ease of installation have allowed the ArduPilot platform to ...
The Parrot AR.Drone is a discontinued remote-controlled flying quadcopter, built by the French company Parrot.. The drone is designed to be controlled by mobile or tablet operating systems, such as iOS or Android [1] within their respective apps or the unofficial software available for Windows Phone, Samsung BADA and Symbian devices.
The Euler angles linking these reference frames are: Earth frame to body frame: yaw angle ψ, pitch angle θ, and roll angle φ; Earth frame to wind frame: heading angle σ, flight-path angle γ, and bank angle μ; Wind frame to body frame: angle of sideslip β, angle of attack α (in this transformation, the angle analogous to φ and μ is ...
