‘MANTABOT’ VEHICLE SWIMS LIKE A RAY
U. VIRGINIA / PRINCETON (US) — Designers are attempting to recreate the relatively effortless but effective swimming movements of stingrays and manta rays by building their own ray-like machine.
Batoid rays, such as stingrays and manta rays, are amongst nature's most elegant swimmers. They are fast, highly maneuverable, stylish, energy-efficient, and can cruise, bird-like, for fars away in the deep, open up sea, and hinge on the sea bottom.

"They are wonderful instances of ideal design naturally," says Hilary Bart-Smith, an partner teacher of mechanical and aerospace design in the College of Virginia‘s Institution of Design and Used Scientific research.
They are designing an "self-governing undersea vehicle" that one day may surpass what nature has provided as a design. The vehicle has potential industrial and military applications, and could be used for undersea expedition and clinical research.
Copying nature
Sometimes called "biomimicry"—the attempt to copy nature—Bart-Smith phone telephone calls her work "bio-inspired."
"We are examining an animal to understand how it has the ability to swim so wonderfully, and we are wishing to surpass it," she says. "We are learning from nature, but we also are innovating; attempting to move past emulation."
Bart-Smith's group, that includes scientists at College of Virginia, Princeton College, the College of California, Los Angeles, and West Chester College, are modeling their mechanical ray on the cow-nosed ray, a species common to the western Atlantic and Chesapeake Bay.
The staff member, that are experts in aquatic biology, biomechanics, frameworks, hydrodynamics and control systems, have produced a model molded straight from a genuine cow-nosed ray.
By examining the movements of living rays in the area and the lab and through dissection, this model attempts to duplicate the near-silent flaps of the wing-like pectoral fins of a ray, to swim ahead, transform, accelerate, move, and maintain position.
"Biology has refixed the problem of mobility with these pets, so we need to understand the systems if we are mosting likely to not just copy how the pet swims, but potentially also to surpass it," Bart-Smith says.
Her group is attempting to accomplish ideal quiet propulsion with a minimal input of power.
Stealth monitoring
Scientists from another location control the mechanical ray via computer system commands. The plastic body of the vehicle includes electronic devices and a battery, while the versatile silicone wings include poles and cable televisions that expand and pull back and change form to facilitate what is basically undersea trip.
Bart-Smith's supreme objective is to designer a car that would certainly run autonomously, and could be released for lengthy time periods to gather undersea information for researchers, or as a monitoring device for the military.
It also could be scaled up, or down, to function as a system bring various payloads, such as ecological monitoring tools. For instance, it potentially could be used for pollution monitoring, such as monitoring the locations of undersea oil spills.
And because the vehicle appearances and acts such as a common sea animal, it most likely would certainly run in the sea without impacting all-natural animals or their habitats
