In this paper, we present the design and implementation of POSSE, a new, lightweight computational steering system based on a client/server programming model. We demonstrate the effectiveness of this software system by illustrating its use for a visualization client designed for a particularly demanding real-time application—wake-vortex simulations for(More)
This paper describes an intelligent autonomous airborne flight capability that is being used as a test bed for future technology development. The unmanned air vehicles (UAVs) fly under autonomous control of both an onboard computer and an autopilot. The onboard computer provides the mission control and runs the autonomous Intelligent Controller (IC)(More)
—The need for intelligent unmanned vehicles has been steadily increasing. These vehicles could be air-, ground-, space-, or sea-based. This paper will review some of the most common software systems and methods that could be used for controlling such vehicles. Early attempts at mobile robots were confined to simple laboratory environments. For vehicles to(More)
This paper describes the development of a system that uses computational psychology (the Soar cognitive architecture) for the control of unmanned vehicles. A multithreaded software system written using Java and integrated with the Soar cognitive architecture has been implemented on two types of mobile robots. Soar can be used as a general purpose robotic(More)
The possibility of predicting the full three-dimensional, unsteady, separated flow around complex ship and helicopter geometries is explored using un-structured grids in a parallel flow solver. The flow solver used is a modified version of the Parallel Un-structured Maritime Aerodynamics (PUMA) software. Since this requires immense computational resources,(More)
— This paper describes an implementation of an autonomous Intelligent Controller (IC) architecture for collab-orative control of multiple unmanned aerial vehicles (UAVs). Collaborative capabilities include formation flying, search of an area, and cooperative investigation of a target. The IC provides capabilities for sensor data fusion, internal(More)
