We experimented a lot, but up until today we did not yet succeed in getting the bird in the air with the home build electronics. Such constraints are dynamic constraints and require the state. A mathematical model of a quadrotor UAV is defined on the special Euclidean group, and nonlinear output‐tracking controllers are developed to follow (i) an attitude command, and (ii) a position command for the vehicle center of mass. quadrotor, as depicted in Figure 4, is a rotary wing UAV, consisting of four rotors located a t the ends of a cross structure. In a video that similar to those videos where humans push around ATLAS, researchers at Delft University of Technology have created a system that will let a quadrotor drone keep flying even if one.

A well-accepted model for quadrotor vehicles is used, with simulation parameters compara-ble to those of a small commercial quadrotor.
