1. 1. Exploration and Mapping of Warehouses Using QuadrotorHelicopters

   Master-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Författare :Yuantao Fan; Maytheewat Aramrattana; [2013]
   Nyckelord :;

   Sammanfattning : The goal of this thesis work is mapping of warehouse infrastructure using AR.Drone, aquadro helicopter equipped with a wide angle camera as its main sensor for mapping.Parallel Tracking and Mapping algorithm is employed for localization and creationof 3D point cloud of corner feature in the environment.

3. 2. Autonomus Helicopter Landing on a Mobile Platform.

   Kandidat-uppsats, KTH/Optimeringslära och systemteori

   Författare :Rasmus Hansén; Axel Ringh; Victoria Svedberg; Nils Landin; [2011]
   Nyckelord :;

   Sammanfattning : In this thesis we investigate the problem of landing a helicopter autonomously on a mobile platform by designing controllers for the attitude- and translational dynamics in parallel. A mathematical model of the helicopter, in form of general 6-degrees-of-freedom rigid-body dynamics with application-specific actuations, is developed. LÄS MER

4. 3. Investigation of rotor downwash effects using CFD

   Sammanfattning : This paper is the result of a master thesis project on helicopter rotor downwash effects using computational fluid dynamics (CFD). The work was performed at the department of Aerodynamics and Flight Mechanics at Saab AB, Linköping in 2008. It completes the author’s studies for a M. LÄS MER

5. 4. Modelling, Identification and Control of a Quadrotor Helicopter

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Tammaso Bresciani; [2008]
   Nyckelord :System Identification; PID Control; VTOL; UAV; Quadrotor; Technology and Engineering;

   Sammanfattning : This thesis work focused on the study of a quadrotor helicopter. The dynamic system modelling and the control algorithm evaluation were carried out. To test the results, a simulator and a real platform were developed. The Newton-Euler formalism was used to model the dynamic system. LÄS MER
