Morphing aircraft can alter their aerodynamic configuration to obtain multitask adaptability and improve flight performance. In this paper, we apply the variable sweep concept on a tandem-wing micro aerial vehicle (MAV) for adaptability, two canards of which undergo backward wings forward sweep. The morphing mode not only weaken additional inertia forces moments caused by morphing, but also mai...

This is a final report on the research studies completed under NASA Grant NAG 1-03045, “Development of Micro Air Vehicle Technology with In-Flight Adaptrive-Wing Structure.” This project involved the development of variable-camber technology to achieve efficient design of micro air vehicles. Specifically, it focused on the following topics: 1) Low Reynolds number wind tunnel testing of cambered...

Unmanned aerial vehicles (UAV) and micro air vehicles (MAV) are already intensively used in geodetic applications. State of the art autonomous systems are however geared towards the application area in safe and obstacle-free altitudes greater than 30 meters. Applications at lower altitudes still require a human pilot. A new application field will be the reconstruction of structures and building...

Feature tracking is an integral part of most vision-based state estimation frameworks. However, tracking features at a sufficient frame rate is a challenging task for mobile robots such as Micro Aerial Vehicles (MAVs) due to their fast dynamics and limited on-board computing resources. Recent developments in smartphone processors have led to embedded computing platforms that are ideal on-board ...

ABSTRACT Introduction: The continuous improvement of the level modern sports competition compels reform and constant updates on training theory; research is migrating from low-intensity to high-intensity interval, many studies have shown that interval has a good effect athletes. Objective: Investigate different recovery modalities during athletic performance young male runners. Methods: Using b...

Understanding forest functioning is limited by the scalability of monitoring solutions and difficulty access. Manual sensor placement can reach most locations but lacks scalability. Micro-aerial vehicles (MAVs) allow for scalable delivery, current are to attaching sensors trunk or large branches with spines adhesives. The thinner outer canopy remain inaccessible, despite being particular intere...

We present a framework for performing collaborative localization groups of micro aerial vehicles (MAV) that use vision-based sensing. The are each assumed to be equipped with monocular camera, and capable communicating other. This approach is developed as decentralized algorithm built in distributed fashion where individual relative pose estimation techniques combined the group localize against...
