SPURV II
SPURV II, short for Special Purpose Underwater Research Vehicle, was an Autonomous Underwater Vehicle built at the Ocean Physics Department at the Applied Physics Laboratory at the University of Washington in 1973 to study Ballistic missile submarine, SSBN wakes. Capability SPURV II had variable speed, and could run for about 6 hours to depths of 1500 meters. It carried instruments to measure temperature and velocity with taken at 1 kHz, temperature and conductivity taken at 100 Hz, and temperature conductivity, pressure, and dye concentration at 10 Hz. SPURV II was quite a bit different in its 1975 operational state than its final 1979 state. The instrumentation and the internal recording system capacity were significantly increased, and all of the sensors—temperature and velocity at 1 kHz, temperature, conductivity and velocity at 100 Hz, and (more precisely) temperature, conductivity, dye concentration, and pressure (depth) at 10 Hz—could be ...

Autonomous Underwater Vehicle
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs. History The first AUV was developed at the Applied Physics Laboratory at the University of Washington as early as 1957 by Stan Murphy, Bob Francois and later on, Terry Ewart. The "Special Purpose Underwater Research Vehicle", or SPURV, was used to study diffusion, acoustic transmission, and submarine wakes. Other early AUVs were developed at the Massachusetts Institute of Technology in the 1970s. One of these is on display in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Washington
The University of Washington (UW, simply Washington, or informally U-Dub) is a public research university in Seattle, Washington. Founded in 1861, Washington is one of the oldest universities on the West Coast; it was established in Seattle approximately a decade after the city's founding. The university has a 703 acre main campus located in the city's University District, as well as campuses in Tacoma and Bothell. Overall, UW encompasses over 500 buildings and over 20 million gross square footage of space, including one of the largest library systems in the world with more than 26 university libraries, art centers, museums, laboratories, lecture halls, and stadiums. The university offers degrees through 140 departments, and functions on a quarter system. Washington is the flagship institution of the six public universities in Washington state. It is known for its medical, engineering, and scientific research. Washington is a member of the Association of American Universiti ...

Ballistic Missile Submarine
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. The United States Navy's hull classification symbols for ballistic missile submarines are SSB and SSBN – the ''SS'' denotes submarine, the ''B'' denotes ballistic missile, and the ''N'' denotes that the submarine is nuclear powered. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect (see acoustic signature), thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence. The deployment of SSBNs is dominated by the United States and Russia (following the collapse of the Soviet Union). Smaller numbers are in service with France, the United Kingdom, China and India; North Korea is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPURV
SPURV, or Self-Propelled Underwater Research Vehicle, was an Autonomous Underwater Vehicle built in 1957 at the University of Washington's Applied Physics Laboratory. The research and development of this vehicle was funded by the United States Office of Naval Research (ONR), and it became the US Navy’s first autonomous underwater vehicle (AUV). The navy used a total of 7 SPURV vehicles until 1979. Construction The original engineers of SPURV were Bob Van Wagennen (mechanical) and Wayne Nodland (electrical). Terry Ewart calculated the hydrodynamics design on a Berkeley EASE analog computer. SPURV was machined by Boeing from a forging of 7078-T6 aluminum. Capability SPURV had an operating depth of at least 3000 meters and a maximum depth of 3600 meters. It could go about 4-5 knots for about 4 hours. A propulsion battery consisting of 2 sets of 16 silver zinc cells connected in a parallel through diodes was the primary power source for SPURV. The battery provided a 24-volt, 200 ...

Robotic Submarines
Robotics is an interdisciplinarity, interdisciplinary branch of computer science and engineering. Robotics involves design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrates fields of mechanical engineering, electrical engineering, Information engineering (field), information engineering, mechatronics, electronics, bioengineering, computer engineering, control engineering, software engineering, mathematics, etc. Robotics develops machines that can substitute for humans and replicate human actions. Robots can be used in many situations for many purposes, but today many are used in dangerous environments (including inspection of radioactive materials, bomb detection and bomb disposal, deactivation), manufacturing processes, or where humans cannot survive (e.g. in space, underwater, in high heat, and clean up and containment of hazardous materials and radiation). Robots can take any form, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autonomous Underwater Vehicles
In developmental psychology and moral, political, and bioethical philosophy, autonomy, from , ''autonomos'', from αὐτο- ''auto-'' "self" and νόμος ''nomos'', "law", hence when combined understood to mean "one who gives oneself one's own law" is the capacity to make an informed, uncoerced decision. Autonomous organizations or institutions are independent or self-governing. Autonomy can also be defined from a human resources perspective, where it denotes a (relatively high) level of discretion granted to an employee in his or her work. In such cases, autonomy is known to generally increase job satisfaction. Self-actualized individuals are thought to operate autonomously of external expectations. In a medical context, respect for a patient's personal autonomy is considered one of many fundamental ethical principles in medicine. Sociology In the sociology of knowledge, a controversy over the boundaries of autonomy inhibited analysis of any concept beyond relative autonomy ...
