2020-12-11 This article proposes a method of measuring wind speed using the data logged by the autopilot of a quadrotor drone. Theoretical equations from works on quadrotor control are utilized and supplemented to form the theoretical framework. Static thrust tests provide the necessary parameters for calculating wind estimates. Flight tests were conducted at a test site with laminar wind conditions with Mapping and 3D modelling using quadrotor drone and GIS software. March 2021; Journal of Big Data 8(1) DOI:10.1186 The drone is also supported by a high-quality camera with dreadlocks for using quadrotor drones [27,28]. All the flight controls of a quadrotor drone are based on variation of the speeds of the four rotors. Hence, a strong down flow occurs during the flight of a quadrotor drone, resulting in vortex and wake phenomena [29], which could interfere with the detection capability of an integrated chemical sensor.
With four independent rotors, the need for a swashplate mechanism is alleviated. The swashplate mechanism was needed to allow Quadrotor Helicopter Flight Dynamics and Control: Theory and Experiment∗ Gabriel M. Hoffmann† Haomiao Huang‡ Steven L. Waslander§ Claire J. Tomlin ¶ Quadrotor helicopters are emerging as a popular platform for unmanned aerial vehicle (UAV) research, due to the simplicity of their construction and maintenance, their ability Drone, Quadcopters, UAV's. Whatever you want to call them, give you the freedom to feel free. To fly up and soar to areas we could only have dreamed of 20 years ago. with the technology being more affordable than ever before, this site will give users of all abilities somewhere to come, so they can share their experiences and flights. Modelling, Identification and Control of a Quadrotor Helicopter (Modellering, identifiering och reglering av en quadrotor helikopter) Abstract This thesis work focused on the study of a quadrotor helicopter.
Fixed-wing drones have problems in cities. They cannot easily fly down narrow streets and alleys, and certainly not inside buildings.

The quadrotor vehicle operates on the concept of variable torques and thrusts. Each rotor consists of a brushless DC motor and rotor with a fixed pitch.
