Modeling the Quad-Rotor Mini-Rotorcraft,e quad-rotor modeling is addressed using two different approaches: Euler–Lagrange and Newton–Euler. How to derive Lagrange’s equations from Newton’s equations is also shown. Finally, the author presents also the Newton–Euler modeling for an “X-Flyer” quad-rotor configuration.

Imaging Sensors for State Estimation,heoretical background concerning computer vision is given in first instance. The pinhole camera model as well as the camera calibration procedure is shown. Stereo imaging, together with a method for stereo calibration and rectification are presented also. The concept of optical flow and a method for

Vision-Based Control of a Quad-Rotor UAV,ography estimation technique and an optical flow computation. Using this approach, a comparison of three control methods is addressed, with the purpose of validating the most effective approach for stabilizing the vehicle when using visual feedback. In the second strategy, the vision system is imple
