Miniature unmanned aerial vehicles (UAVs) and unmanned vertical take-off and landing (VTOL) vehicles have become popular due to their compact size, high maneuverability and high payload-to-size ratio. Such vehicles have shown great potential in surveillance and search and rescue; however the “onthe-ground” processing methods implemented are rather insufficient. This paper presents a low cost, h...

This paper concerns the control of Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vechicles (UAVs) based on exteroceptive measurements obtained from a mono-camera vision system. By assuming the existence of a locally planar structure in the field of view of the UAV’s camera, the so-called homography matrix can be used to represent the vehicle’s motion between two views of the structure. I...

Abstract As part of an envisioned autonomous swarm exploration mission in Valles Marineris on Mars a design investigation high-range scout UAV is performed this work. Two VTOL configurations, coaxial helicopter and transition tailsitter, are examined to assess their suitability. A preliminary framework using Python the optimization OpenMDAO created software NDARC. To model rotor performance, co...

Quadrotors are rapidly emerging as a popular platform for unmanned aerial vehicle (UAV) research, due to the simplicity of their construction and maintenance, their ability to hover, and their vertical take off and landing (VTOL) capability. Current designs have often considered only nominal operating conditions for vehicle control design. This work seeks to address issues that arise when devia...

Autonomous Unmanned Aerial Vehicles (UAVs) require avionics systems that enable them to maintain a stable attitude and to follow a desired flight path. This paper considers the design and development of such an avionics system that provides navigational and terrain information to the flight computer of a rotorcraft UAV. The process includes the design and testing of flight hardware and software...

The US Army has plans to deploy a dedicated UAV system at every echelon. However, there are disadvantages to fielding such a large number of different and separately controlled vehicles. This research addresses one key part of this issue of selecting the right mix of UAV systems: How shall a company be supported? We consider two alternatives for the company commander, loosely based on systems c...

The studies in UAV modeling and control have been increased rapidly recently. This paper presents the modeling and control of a four rotor vertical take-off and landing (VTOL) unmanned air vehicle known as quadrotor aircraft. The modeling of the quadrotor will be described by using Euler-Newton equations. In order to stable the quadrotor and control the attitude of that, classical PID controlle...

The Man-Portable Networked Sensor System (MPNSS), with its baseline sensor suite of a pan/tilt unit with video and FLIR cameras and laser rangefinder, functions in a distributed network of remote sensing packages and control stations designed to provide a rapidly deployable, extended-range surveillance capability for a wide variety of security operations and other tactical missions. While first...

The number of Unmanned Aerial Vehicles (UAVs) continues to explode. Within the total spectrum Aircraft System (UAS) operations, Urban Air Mobility (UAM) is also on way. Dense air traffic getting ever closer us. Current research either focuses network design and route for safety purpose or swarm control in open airspace contain large volume UAVs. In order achieve a tradeoff between volumes UAVs,...
