Drone applications master thesis

Comment Multi-rotor Unmanned Aerial Vehicles UAVs high maneuverability and their capability to hover, makes them an extensively used platform in many fields of applications.

Due to the multiple rotors, they are extremely easy to steer, making them far more applicable for situations other than simply travelling from one point to another compared to their counterparts like planes and helicopters.

However, their limitations in flight time challenge the ambition of using multirotor UAVs in fully autonomous operations. To achieve a seamless synergy between the UAVs and the vehicle including a landing pad, requires the UAV to be able to perform autonomous landing on the landing pad while it is in motion.

Landing on a moving platform is easier said drone applications master thesis done. We might have seen a number of action movies where a helicopter lands on a moving vehicle but in the real world during real time situations, it is extremely difficult to access all the factors associated with such a landing and making it work safely.

Mentioned below are some possible methods to achieve the said task: Sensors on both the UAV and the moving platform: An Accelerometer often comes with a gyro sensor installed with it. Installing this sensor, or a more advanced sophisticated sensor on both the flying craft and the moving platform will allow the controller in the UAV to decide the perfect speed and direction for the UAV to land on the platform.

We have talked about image processing before, it is the use of simple cameras to understand the environment around the camera; the same way we interpret our environment when we see it with our eyes and process what we see with our brains.

A camera is able to decide the distance between the drone and the moving platform and the relative velocity between the two. Not only that, a camera can also decide the best location on the said platform to land on and adjust the drone according to the platform during landing.

To measure the pose of the landing pad relative to the UAV, a camera based measurement system for detecting fiducial markers was implemented as an image processing module.

The imaging processing module has been extensively tested under various scenarios, such as winter conditions, bright summer sunlight at sea and indoor, all given reliable and accurate results.

The two guidance methods Parallel Navigation Guidance and Optimal Guidance These methods were discussed and compared using simulations. In the Optimal Guidance method it is possible to add constraints, such as restrictions in the flight area or control output.

However, this guidance method has a high computational cost compared to the Parallel Guidance method and it is harder to implement. Controller logic was developed to set the desired UAV trajectory, velocities and controller gains. The image processing module, the state estimator, the Parallel Navigation method and the controller logic were all implemented and running in real time on the UAV.

Results from physical tests indicates that the combination of the state estimator and the Parallel Navigation Guidance method ensures robust and accurate autonomous landing on a static target.

Additionally, results from the tuned state estimator and simulations indicated that the system is able to carry out autonomous landing on landing pads in motion.

Landing has been conducted both on ground and a surface vehicles containing world class navigation system, and on a homemade landing pad containing a low cost navigation system. FFI will use the state estimator, guidance method and the controller logic developed in this project on their attempt to create fully autonomous drone swarms.Jun 17,  · Master’s UAV Project Takes Flight.

My passion lies in applying innovative tion on drones and their application for nature conservation. Finally, at the end of this chapter. Naval Postgraduate School Center for Homeland Defense and Security master’s degree student Craig Schwartz, Captain with the Santa Rosa (California) Police Department, believes a public agency’s drone program is as much about community trust as it is about gadgetry and situational awareness.

The drone system was assembled in a Bachelor thesis and extensively tested on the PV LABs own roof-top PV-installation. Application to two large Swiss PV-installations (football stadium “Stade.
