It is well-known that autonomous underwater vehicle (AUV) missions are a challenging, high-risk robotics application. With many parallels to Mars rovers, AUV missions involve operating a vehicle in an inherently uncertain environment of which our prior knowledge is often sparse or low-resolution. The lack of an accurate prior, coupled with poor situational awareness and potentially significant sensor...
The current paper discusses how 3-dimensional Forward Looking Sonar (3D FLS) technology can be used to improve the safety of navigation around offshore wind farms (OWFs). The authors make the case that although the use of 3D FLS is not widespread at present, the rapid growth in the number, and sizes of offshore wind turbines presents a formidable challenge for the maritime industry. In order to prepare...
The performance of a navigating officer in critical situations is uncertain and has to be considered in a probabilistic framework, since this may provide an in depth insight in the human - machine interaction. Such a systematic approach will have the objective to understand, to predict and to minimize the role of the human as a causal factor for a casualty in terms of the time sequence needed to perform...
Scientific principles of ground navigation visual aids -lighting systems - design for civil aviation aerodromes are suggested. All grounds based on modern international standards and recommended practice.
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...
Robots will more and more enter our daily life. In order to increase their acceptance it is necessary that their movements and behavior are predictable. With our present experiment we assess the acceptance of autonomous robots in human working and living environments. As a specific indicator we define legibility as an important prerequisite for user acceptance. In a simulator study participants rated...
An automated method for sea route design based on electronic chart is developed to improve the security and reliability of planned sea route. First, the obstacle projection matrix is built based on the environmental information provided by electronic chart. Then a basic path is built quickly by using the adjacent relation among girds. Finally, elastic algorithm was used to optimize the basic path...
A shortest routing is crucial in emergent navigations including rescue and military applications. This paper proposes an automatic method of the shortest routing for emergent navigation. Firstly, un-navigable shallow areas are obtained by tracing safety contour for the ship navigation, and they are processed together with other obstacle areas. Then navigable paths are tested based on the predefined...
