    Unmanned aerial rotorcraft vehicles have many military, commercial and civil applications. There is a necessity to advance the performance on several ranges of rotorcraft for using these vehicles successfully in the expanded future roles. A lower flight time, noise disturbance and safety issues remain the key obstacles in increasing the efficiency of the rotorcraft for various applications. This work presents the design and realization of a rotorcraft using pressurized inflatable structure filled with lighter than air gas such as helium or hydrogen to provide lift assistance for the vehicle. Two iterative design procedures were developed for designing the vehicle. One is based on the net weight of the vehicle and the other based on the diameter of the pressurized structure. Fabrication of a design based on the diameter of the pressurized structure is analysed and evaluated. Gross static lift, the correlation between the size of the inflatable structure and lift force produced, lifting gas properties in the flight range, stress on the structure, and the maximum achievable altitude is also discussed. The vehicle possesses the potential to overcome some inherent limitations of the current unmanned aerial rotorcraft vehicles. This work holds an excellent prospect for future research and more isolated development in all the applications this particular system can be employed

We first perform optimization of rotor distribution to maximize control wrench generation in SE(3) while minimizing aero-dynamic interference among the rotors. We present dynamics modeling of the ODAR system in SE(3) and simultaneous translation / orientation control design. We also implement a ODAR system and experimentally validate its performance. Being completely different from the conventional drone, we believe this ODAR system would be promising for such applications as aerial manipulation, where omni-directional wrench generation is important, and also as aerial photography, where an ability to taking photos in omni-direction is desired for 3D environment reconstruction for VR scene rendering.1 ์„œ๋ก  1 1.1 ์—ฐ๊ตฌ ๋™๊ธฐ ๋ฐ ๋ชฉ์  1 1.2 ์—ฐ๊ตฌ ์„ฑ๊ณผ 4 2 ์‹œ์Šคํ…œ ๋””์ž์ธ ๋ฐ ์ œ์–ด ์„ค๊ณ„ 6 2.1 ์‹œ์Šคํ…œ ๋””์ž์ธ 6 2.2 ์ œ์–ด ์„ค๊ณ„ 16 3 ์‹œ๋ฎฌ๋ ˆ์ด์…˜ 21 3.1 ์‹œ๋ฎฌ๋ ˆ์ด์…˜ ์ค€๋น„ 21 3.2 ์‹œ๋ฎฌ๋ ˆ์ด์…˜ ๊ฒฐ๊ณผ 24 4 ์‹œ์Šคํ…œ ์ œ์ž‘ 27 4.1 ์‹œ์Šคํ…œ ์ œ์ž‘ ์ค€๋น„ 27 4.2 ์‹œ์Šคํ…œ ์ œ์ž‘ ๊ตฌ์„ฑํ’ˆ 28 4.3 ์‹œ์Šคํ…œ ์ œ์ž‘ ํ†ตํ•ฉ 34 5 ์‹คํ—˜ 36 5.1 ์‹คํ—˜ ์ค€๋น„ 36 5.2 ์‹คํ—˜ ๊ฒฐ๊ณผ 38 5.2.1 ์›ํ˜• ๊ถค์  ์ถ”์  39 5.2.2 3D ์˜์ƒ์ดฌ์˜ ๋ชจ์…˜ 42 5.2.3 ์ˆ˜์ง ๊ตฌ๋™ ์ž‘์—… 45 6 ๊ฒฐ๋ก  49 6.1 ๊ฒฐ๋ก  49 6.2 ํ–ฅํ›„ ๊ณผ์ œ 50 ์ฐธ๊ณ ๋ฌธํ—Œ 52 Abstract 57Maste

    In this thesis are analyzed different and innovative techniques for Human Robot Interaction. The focus of this thesis is on the interaction with flying robots. The first part is a preliminary description of the state of the art interactions techniques. Then the first project is Fly4SmartCity, where it is analyzed the interaction between humans (the citizen and the operator) and drones mediated by a cloud robotics platform. Then there is an application of the sliding autonomy paradigm and the analysis of different degrees of autonomy supported by a cloud robotics platform. The last part is dedicated to the most innovative technique for human-drone interaction in the Userโ€™s Flying Organizer project (UFO project). This project wants to develop a flying robot able to project information into the environment exploiting concepts of Spatial Augmented Realit
