No question about it… they're very good at what they do. But they don't take well to orders, especially those to carry out inspection work in oily or dangerous environments, or in any kind of harsh environment, for that matter.
The tuna has a natural body framework ideal for unmanned underwater vehicles (UUVs), solving some of the propulsion and maneuverability problems that plague conventional UUVs. BIOSwimmer™ is a UUV inspired by the tuna and designed for high maneuverability in harsh environments, with a flexible aft section and appropriately placed sets of pectoral and other fins.

Still, they're one of the fastest and most maneuverable creatures on the planet, having extraordinary abilities at both high and low speeds due to their streamlined bodies and a finely tuned muscular/sensory/control system.
This impressive creature is the humble tuna fish.
The Department of Homeland Security's (DHS) Science and Technology Directorate (S&T) is funding the development of an unmanned underwater vehicle designed to resemble a tuna, called the BIOSwimmer™. Why the tuna? Because the tuna has a natural body framework ideal for unmanned underwater vehicles (UUVs), solving some of the propulsion and maneuverability problems that plague conventional UUVs.
Inspired by the real tuna, BIOSwimmer™ is a UUV designed for high maneuverability in harsh environments, with a flexible aft section and appropriately placed sets of pectoral and other fins. For those cluttered and hard-to-reach underwater places where inspection is necessary, the tuna-inspired frame is an optimal design. It can inspect the interior voids of ships such as flooded bilges and tanks, and hard to reach external areas such as steerage, propulsion and sea chests. It can also inspect and protect harbors and piers, perform area searches and carry out other security missions.
Boston Engineering Corporation's Advanced Systems Group (ASG) in Waltham, Massachusetts, is developing the BIOSwimmer™ for S&T. "It's designed to support a variety of tactical missions and with its interchangeable sensor payloads and reconfigurable Operator Controls, can be optimized on a per-mission basis" says the Director of ASG, Mike Rufo.
BIOSwimmer™ is battery-powered and designed for long-duration operation. Like other unmanned underwater vehicles, it uses an onboard computer suite for navigation, sensor processing, and communications. Its Operator Control Unit is laptop-based and provides intuitive control and simple, mission-defined versatility for the user. A unique aspect of this system is the internal components and external sensing which are designed for the challenging environment of constricted spaces and high viscosity fluids
"It's all about distilling the science," says David Taylor, program manager for the BIOSwimmer™ in S&T's Borders and Maritime Security Division. "It's called 'biomimetics.' We're using nature as a basis for design and engineering a system that works exceedingly well.*
Tuna have had millions of years to develop their ability to move in the water with astounding efficiency. Hopefully we won't take that long."
* Biologically inspired robotics (biomimetic robotry) is a fairly new science that is gaining steam. There are now robotic lobsters, flies, geckos, moths, clams, dogs, and even a lamprey-like robot, all being designed to perform a variety of missions including surveillance and search and rescue. Robotics based on sinuous snakes and elephant trunks, for example, may be the ideal way to search for survivors inside the rubble of structures destroyed by explosions or natural disasters.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
