The revolution in the mechatronics field made a new era for the monitoring and supervision of agriculture management systems. In precision agriculture, crop protection drones have great potential due to its flexibility in handling to increase crop productivity. However, the multi-rotor aerial system working capability depends on the required thrust to be produced in order to lift the system from the ground position. This work proposes simulation and theoretical static thrust calculations to develop an autonomous multi-rotor system, which is capable of lifting the components, those are helpful for precision farming. This work starts with an analytical approach of the thrust equation and its influences at various parameters explained. The motion equations are derived using the kinetic energy, disk actuator theory and momentum theory. The thrust is calculated using the parameters, motor specifications, propeller dimensions and constant. If the calculated thrust is twice to the total weight of the multi-rotor system, then the system has the ability to fly comfortably toward the crop agriculture field. The calculation is done for different propellers and chosen the best one. The chosen theoretical result validated using a static thrust calculator in a Web site from “gobrushless.com.” The relative error between the simulated and theoretical results has shown only 2% of the difference.
