Xenosaga

Xenosaga (ゼノサーガ, Zenosāga) is a series of science fiction video games developed by Monolith Soft and published by Bandai Namco. Xenosaga's main story is in the form of a trilogy of PlayStation 2 video games. There have been three spin-off games and an anime adaptation. The Xenosaga series serves as a spiritual successor to the game Xenogears, which was released in 1998 for the PlayStation by Square. The creator of both Xenogears and Xenosaga is Tetsuya Takahashi, who left Square in 1998 along with Hirohide Sugiura. Using funds from Namco, they started MonolithSoft and the Xenosaga project.

The first game in the trilogy, Episode I: Der Wille zur Macht was released in February 2002 in Japan, and in February 2003 in North America. Xenosaga Freaks, a lighthearted game with a playable demo for Episode II, was released in April 2004 in Japan, but was not released elsewhere. Episode II: Jenseits von Gut und Böse was released in June 2004 in Japan and February 2005 in North America. Xenosaga: The Animation, an anime based on Episode I, premiered on TV Asahi in Japan on January 5, 2005. Xenosaga Pied Piper, a three chapter-long cellphone-based game depicting the history of cyborg "Ziggurat 8" 100 years before the start of Episode I, was released in Japan in July 2004. Released on July 6, 2006, Episode III: Also sprach Zarathustra is the final title in the Xenosaga series; six episodes were originally projected, but by the time Episode III was released, Namco had already established that it would be the last entry, effectively halving the series. A retelling of the first two episodes titled Xenosaga I & II was released on the Nintendo DS in March 2006 in Japan.

Autonomous underwater vehicle

An autonomous underwater vehicle (AUV) is a robot which 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 AUVs are more often referred to simply as unmanned undersea vehicles (UUVs).

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 the Hart Nautical Gallery in MIT. At the same time, AUVs were also developed in the Soviet Union (although this was not commonly known until much later).
