One of the weaknesses multi-rotor unmanned aerial vehicles (UAVs) or vertical take-off and landing aircraft is that they need a flat surface to make safe landing. In order reduce impact this weakness, it inevitable add systems will give UAV some additional capabilities related capability. study, four-arm adaptive gear designed kinematically analyzed for UAV. The adaptability feature achieved by...

The capacity of a runway system represents a bottleneck at many international airports. The current practice at airports is to land approaching aircraft on a first-come, first-served basis. An active rescheduling of aircraft landing times increases runway capacity or reduces delays. The problem of finding an optimal schedule for aircraft landings is referred to as the “aircraft landing problem”...

Operation load measurement is an important technique enabling machine health monitoring and fault localization; however, direct measurement is usually difficult or impossible. The paper deals with the development of a smart sensor, which estimates the load based on structure response. In case studies, a hardware neural network was used to obtain the load course from structure vibrations ¡ shake...

Autonomous landing is an essential function for micro air vehicles (MAVs) for many scenarios. We pursue an active perception strategy that enables MAVs with limited onboard sensing and processing capabilities to concurrently assess feasible rooftop landing sites with a vision-based perception system while generating trajectories that balance continued landing site assessment and the requirement...
