Maintaining network connectivity and performance in robot teams: Research Articles

Abstract: In this paper, we present an experimental study of strategies for maintaining end-to-end communication links for tasks such as surveillance, reconnaissance, and target search and identification, where team connectivity is required for situational awareness. Our main contributions are threefold: (a) We present the construction of a radio signal strength map that can be used to plan multi-robot tasks, and also serve as useful perceptual information. We show how a nominal model of an urban environment obtained by aerial surveillance, is used to generate strategies for exploration. (b) We present reactive controllers for communication link maintenance; and (c) we consider the differences between monitoring signal strength versus data throughput. Experimental results, obtained using our multi-robot testbed in three representative urban environments are presented with each of our main contributions. © 2008 Wiley Periodicals, Inc.

Visualization for situational awareness

Abstract: We focus on theater-wide situational awareness covering a large geographic area containing many military units. The Joint Operations Visualization Environment (JOVE), developed at Sarnoff to assist military decision makers, optimizes the display of tactical data for information presentation. JOVE uses three rear-projected displays driven from an SGI Onyx2 Infinite Reality2 computer. Stereoscopic display is available. A joystick, graphical user interface, and speech commands provide interaction. JOVE delivers accurate navigation through the model over a range of viewer positions. This case study describes techniques used for effectively modeling and navigating geospatial and tactical data for situational awareness. The visualization technology could be applied to commercial air traffic control, emergency management response, and geographic information systems as well.

Visual Analytics for the Detection of Anomalous Maritime Behavior

Abstract: The surveillance of large sea areas often generates huge amounts of multidimensional data. Exploring, analyzing and finding anomalous behavior within this data is a complex task. Confident decisions upon the abnormality of a particular vessel behavior require a certain level of situation awareness that may be difficult to achieve when the operator is overloaded by the available information. Based on a visual analytics process model, we present a novel system that supports the acquisition of situation awareness and the involvement of the user in the anomaly detection process using two layers of interactive visualizations. The system uses an interactive data mining module that supports the insertion of the user's knowledge and experience in the creation, validation and continuous update of the normal model of the environment.

Using live video for information sharing in emergency response work

Abstract: This paper presents findings from a design-oriented study focusing on emergency response work. Traditionally, Information Technology (IT) for emergency response work has included en route navigation advice, resource management, hazard material databases, property information repositories and situation reporting using sketching functionality. Now, a new class of IT has become available, namely mobile live video capabilities. This paper presents initial findings from a study on how mobile live video capabilities can improve information sharing and situation awareness in emergency response work.
