#Autonomous drones flock like birds Autonomous drone flock The first drones that can fly as a coordinated flock has been created by Hungarian researchers.#
Drones are designed typically to fly alone, and although other research groups have created flocks before, Vicsek says that those attempts involved cutting some corners the copters were restricted to indoor arenas or controlled by a central computer.
According to Vicsek, the only other truly autonomous drone flock was created in 2011 by robotics researcher Dario Floreano at The swiss Federal Institute of technology in Lausanne1.
By contrast, his drones can coordinate their movements to form rotating rings or straight lines. If Vicsek tells them that they face a wall with a gap in it,
and these lags mean the drones often get too close to one another or overshoot their mark.
The drones did not flock successfully until the team managed to speed up their reaction times a challenge that Floreano
the drones communicate among themselves via radio, but that sometimes leads to jammed signals. Fitting them with cameras might provide a workaround.

'The next generation of futuristic weapons has arrived. The U s. Navy announced that its high-tech laser weapon is ready to disable
and destroy enemy drones and small boats, should the need arise. The 30-kilowatt laser weapon system (Laws) is housed aboard the USS Ponce,
a naval vessel stationed in the Arabian Gulfa body of water located south of Iraq that separates the Saudi arabian peninsula from Iran.
If an enemy boat or aircraft gets too close to a Navy ship, the laser can deter the threat with an effect known as optical"dazzling."
which will knock out the sensors or control systems on an enemy drone or vessel. If the adversary still doesn't get the hint,
In recent tests, Laws successfully hit targets aboard a small boat that was speeding toward the Navy ship.
The laser weapon also shot a small drone out of the sky according to Navy officials.""We ran this particular weapon, a prototype, through some extremely tough paces,
and it locked on and destroyed the targets we designated with near-instantaneous lethality,"Klunder,
The sailors who tested Laws reported that the weapon worked well even in high winds,
The data collected from these trial runs will be used to develop new laser weapons for the Navy under the Office of Naval Research's Solid-state laser-Technology Maturation program.
These future lasers could one day be deployed on both large destroyer ships (used to launch missiles) and smaller combat ships
These weapons are sought after because they don require highly explosive gunpowder or pressurized gas to destroy enemy targets,
making them safer for military personnel to operate. And since all they require is a steady supply of electricity,
laser weapons may also be more reliable than conventional weapons. Of course, the U s. military is also pursuing this new breed of weapons for economic reasons.
Laser weapons cost less to build install and fire, compared with multimillion-dollar missiles, Navy officials said."
"At less than a dollar per shot, there's no question about the value Laws provides, "Klunder said."
and Marines are never in a fair fight.""The most recent tests of Laws are part of several rounds of testing that have occurred over the past three years.
In a 2011 test, a laser weapon disabled multiple small boats launched from a U s. warship. And in 2012, Laws downed several drones during a naval test of the system t

Nevertheless tiny submarines that could navigate through the body could be of great benefit: they could deliver drugs precisely to a target location a point on the retina for instance.
Indeed a scallop-shaped miniature submarine could also be driven by an actuator that responds for example to temperature changes.
The tiny submarine could also be used in media other than synovial fluid. Other liquids in which such nanovehicles could deliver drugs for example include the vitreous humor of the eye mucous membranes and even blood.
