This paper describes recent advances in Unmanned Aerial Vehicles aimed at improving their autonomy and reliability for a diverse domain of applications from forest fires and rescue operations to military and border patrol missions. We introduce an experimental VTOL aircraft and discuss instrumentation requirements and control strategies that are essential to maintain stable operations as the ve...

An autonomous robot with vertical take-off and landing (VTOL) capability could be useful for many applications including search and rescue, exploration in hazardous environments, monitoring, surveillance and investigation or even for intelligence. However design of a flight control system for a small UAV is a challenging task. Unlike in conventional aircrafts the control algorithm has to be imp...

The paper concerns the control of Vertical Take Off and Landing (VTOL) Underactuated Aerial Vehicles (UAVs) in hover flight, based on measurements provided by an on-board video camera. The objective is to stabilize the vehicle to the equilibrium pose associated with an image of a planar target, using a minimal sensor suite and poor knowledge of the environment. By using the homography matrix co...

The Vertical Take-off and Landing (VTOL) unmanned aerial vehicles (UAVs) with the tilt-rotor mechanism also known as hybrid UAVs have a lot of challenges in designing controlling concerning their use harsh weather for surveillance access to remote areas. This review paper presents preliminary design aircraft control systems. tilt wings UAV are analyzed. provides an outline technical advances co...

The CL-327 vertical take-off and landing unmanned air vehicle has a payload carrying capability of 100 kg and an on-station endurance of 4.75 hours at 100 km (based on 50 kg payload). Although similar to that of the CL-227, the pitch, roll, yaw and height autopilots have been modified and improved to account for the capabilities and dynamics of the CL327. The advanced guidance, navigation and c...

The main performance characteristics of a helicopter is its fuel consumption. This paper reports the current state in an ongoing project seeking a fast and approximative implementation of mathematical models for helicopter performance predictions, primarily in terms of fuel consumption. The model is limited to a subset of the normal operation modes, only including hover, climb and forward. Also...

When considering the operation of an Unmanned Aerial Vehicle (UAV) or an Unmanned Ground Vehicle (UGV), such problems as landing site estimation or robot path planning become a concern. Deciding if an area of terrain has a level enough slope and a wide enough area to land a Vertical Take Off and Landing (VTOL) UAV or if an area of terrain is traversable by a ground robot is reliant on data gath...

To participate in the Outback Medical Express UAV Challenge 2016, a vehicle was designed and tested that can hover precisely, takeoff and land vertically, fly fast forward efficiently and use computer vision to locate a person and a suitable landing location. A rotor blade was designed that can deliver sufficient thrust in hover, while still being efficient in fast forward flight. Energy measur...

As a new mode of transportation in the future, electric vertical take-off and landing unmanned aerial vehicles (eVTOL UAV) can undertake task logistics distribution carry people urban areas. It is challenging to out research designed plan path eVTOL UAVs which have safe sustainable operation Therefore, this work proposes method for planning an obstacle-free areas with goal minimizing energy con...
