Hydrodynamic coefficients are the foundation of unmanned underwater vehicles modeling and controller design. In order to reduce identification complexity and acquire necessary hydrodynamic coefficients for controllers design, the motion of the unmanned underwater vehicle was separated into vertical motion and horizontal motion models. Hydrodynamic coefficients were regarded as mapping parameter...

Unmanned systems are physical devices or systems equipped with necessary data processing units, sensors, automatic control, and communications systems that can perform desired tasks in unstructured environments without continuous human guidance. A fully autonomous unmanned system has the ability to gain information about and navigate through an environment, to work for an extended period withou...

This article describes the features and advantages of IPS in Unmanned Aerial Vehicle remote sensing image processing processes and software. Examples validate the software can he able to quickly meet the massive Unmanned Aerial Vehicl remote sensing data processing, remote sensing image data processing for the Unmanned Aerial Vehicle market provides a practical and effective solution.

As unmanned systems continue to evolve and their presence becomes more prolific, new methods are needed for training people to interact with these systems. Likewise, new interfaces must be developed to take advantage of the increasing capabilities of these platforms. However, the complexity of such interfaces must not grow in parallel with advancements in unmanned systems technology. A common f...

in this paper, we present the results of a hierarchical slam/gps/ins/wlfp sensor fusion to be used in navigation system devices. due to low quality of the inertial sensors, even a short-term gps failure can lower the integrated navigation performance significantly. in addition, in gps denied environments, most navigation systems need a separate assisting resource, in order to increase the avail...

This paper discusses the requirements, design and operational aspects of the Unmanned Marine Vehicles (UMVs), namely the Romeo Remotely Operated Vehicle (ROV) and the Charlie Unmanned Surface Vehicle (USV), developed at CNR-ISSIA, Genova, Italy for robotics research and scientific applications, pointing out the synergies between the development of underwater and surface unmanned vehicles.

Aim As one of the most diverse and economically important families on Earth, ground beetles (Carabidae) are viewed as a key barometer climate change. Recent meta-analyses provide equivocal evidence abundance changes terrestrial insects. Generalizations from traits (e.g., body size, diets, flights) insights into understanding community responses, but syntheses for Carabidae have not yet emerged....

The use of unmanned vehicle networks for diverse applications is becoming widespread. It is generally hard to program unmanned vehicle networks as a “whole”, however. The coordination of multiple vehicles requires careful planning through intricate human intervention, and a high degree of informality is implied in what concerns the specification of a “network program” for an application scenari...
