Irrigated row-crop agriculture is contributing to declining groundwater in areas such as the Mississippi Delta region of eastern Arkansas. There is a need to move toward sustainable levels of groundwater withdrawal. Recent improvements in remote monitoring technologies such as wireless soil moisture sensors and unmanned aerial vehicles offer the potential for farmers to effectively practice sit...

Demonstrating the reliability of flight control algorithms is critical to integrating unmanned aircraft systems into the civilian airspace. For many potential applications, design and certification of these algorithms will rely heavily on mathematical models of the aircraft dynamics. Therefore, the aerospace community must develop flight test platforms to support the advancement of model-based ...

The paper is dedicated to determination of equipped with a video camera unmanned mobile object (e.g., a mobile robot) orientation by natural landmarks. The problem is relevant for solving the problem of autonomous movement of the mobile object at a given point of navigating using natural landmarks linked to the map location. The algorithm for determining the orientation of an unmanned mobile ob...

Unmanned aerial and ground vehicle teams present a majoropportunity for expanded operation over individual autonomous vehicles alone. The different perspectives available for sensors, the different operating ranges and payload capabilities, and the ability to observe a target environment from all angles at once all add up to significant improvements in ability to search for and track targets, t...

Recent development in unmanned space travel [1], agricultural automation [2], archaeological exploration [3] and evolution of military devices [4] shows that the demand for Unmanned Ground Vehicles is strongly increasing. Still most of the implementations appear more like enhanced remote-controlled cars [5] than autonomously acting and decision-taking, thkus "intelligent", robots. As teleoperat...

Unmanned ground vehicle is an autonomous vehicle that mainly capable to do tasks independent of humans. Automated vehicle works during off road navigation and mainly used in military operations. The radio environment on electrically small platforms is changing rapidly. In order to support high speed audio and video, processing needs higher data rates concerned with sending and receiving data pa...

Advances in autonomy have made it possible to invert the typical operator-to-unmanned-vehicle ratio so that a single operator can now control multiple heterogeneous unmanned vehicles. Algorithms used in unmanned-vehicle path planning and task allocation typically have an objective function that only takes into account variables initially identified by designers with set weightings. This canmake...

A new design for an immersive ground control station is presented that allows operators to monitor and control one or more semi-autonomous unmanned remote vehicles. This new ground station utilizes a virtual reality based visualization of the operational space and the graphical representation of multiple information streams to create a comprehensive immersive environment designed to significant...

OBJECTIVE This study examined the impact of increasing automation replanning rates on operator performance and workload when supervising a decentralized network of heterogeneous unmanned vehicles. BACKGROUND Futuristic unmanned vehicles systems will invert the operator-to-vehicle ratio so that one operator can control multiple dissimilar vehicles connected through a decentralized network.
