The decisional capability of robotic systems has expended significantly in recent years. Their validation typically implies expensive and laborious test campaigns in the field. Part of the validation could use simulation means, but there is currently no systematic method to test robots in virtual worlds. This work aims to provide such a method. We discuss the challenges regarding the definition of...
The ability to navigate in diverse and previously unknown environments is a critical service of autonomous robots. The validation of the navigation software typically involves test campaigns in the field, which are costly and potentially risky for the robot itself or its environment. An alternative approach is to perform simulation-based testing, by immersing the software in virtual worlds. A question...
Toward Autonomous Vehicles Ford is testing remote-control repositioning technology using vehiclemounted cameras and real-time streaming video. With Georgia Techowned golf carts to prove the technology, a person sitting in a remote location can access real-time video, streamed over long-term evolution, to drive the carts. The outcome could be a more affordable and effective way to share or park vehicles...
Software is an integral part of Spacecrafts. Need of complex mission, operator & autonomy requirements have initiated comprehensive On-board software requirements. In order to analyze the design of this complex and evolving requirements, an analysis technique is worked out to identify faults at the lowest level, their propagation and effect on the system. “Software Failure Mode Effect Analysis...
The user evaluation in this paper concerns a domain-specific tool to support the comprehension of large safety-critical component-based software systems for the maritime sector. We discuss the context and motivation of our research, and present the user-specific details of our tool, called FlowTracker. We include a walk-through of the system and present the profiles of our prospective users. Next,...
Det Norske Veritas is a classification society providing standards in the Maritime and Oil&Gas industries. In these industries, Information Technology (IT) usage is increasing rapidly, especially for onboard embedded automation systems, such as propulsion, navigation, steering, power management systems, life support and entertainment systems. The industry needs an increasing level of confidence...
GeoCoastPilot is a research software application built to explore techniques for simplifying access to the navigation information a mariner needs prior to entering or leaving a port. GeoCoastPilot is intended to demonstrate what is possible with current technology and to facilitate technology transfer. We started with the question, "What might a digital application based on the NOAA Coast Pilot...
Boost-phase intercept of a threat intercontinental ballistic missile (ICBM) is the first layer of a multi-layered missile defense strategy. Space-based interceptors possess certain kinematic advantages over ground-based interceptors in defeating an ICBM threat during boost phase. This paper compares the performance of various guidance laws that might be used by an exo-atmospheric kill vehicle (EKV)...
Traffic congestion on major roadways costs our nation billions of dollars in lost earnings, wasted fuel consumption, injury and loss of human life. Providing motorists with real time roadway conditions is essential to mitigating traffic congestion. We propose a novel real-time messaging system that can be used to communicate imminent traffic conditions to motorists. Having such information can allow...
