In this project you will design a controller for a quad-rotor with the objective of regulating its altitude. we will assume that a controller is already in place to ensure the quad-rotor can only move up and down. 1. write the equations of motion for the quad-rotor assumed to be a point mass that can only move along a vertical line and is subjected to the action of two forces: gravity and thrust. 2. knowing that there are 4 propellers, and that each propeller produces a trust force given by: tw 1.536x 10-7ns2 and w is the propeller's t cr is given by cr where the thrust coeffhicien rotational speed, compute the value of w required to make the quad-rotor hoover when its total mass is 0.027 kg
