Hawks and other birds of prey are famous for their keen eyesight.
But researchers have created a roboTIc bird so lifelike that it's even fooled hawks, which swoop down and attack it the way they would any other pigeonlike bird.
Developed at the Maryland Robotics Center, the robot — dubbed Robo Raven — is made of carbon fiber; 3D-printed, lightweight, thermal-resistant plastic; foam; and silvery Mylar foil (for its wings and tail), Military.com reports. [Image Gallery: Remarkable Bionic Animals]
Robo Raven is almost 2 feet long (60 cm) and weighs less than a can of soda. Its original design was developed in 2007 by University of Maryland professors SK Gupta and Hugh Bruck, who carried the battery-powered bird through several evolutions before arriving At the current model.
The long lead time was necessary because, during the trial-and-error process needed to improve the robotic bird, any error would lead to a crash. This would sometimes destroy the robot, so each step in the design process was painstakingly slow.
What makes the current model so realistic is its ability to move each wing independently of the other, just as real birds do. This enables the Robo Raven to swoop, soar, dive and flap its wings in a much more aerobatic way than older models, Whos wings could only move simultaneous.
"Our new robot, Robo Raven, is based on a fundamentally new design concept," Gupta said in a news release. "It uses two programmable motors that can be synchronized electronically to coordinate motion between the wings."
Some of the design improvements to the Robo Raven were inspired by designs found in nature. For example, the robot uses a hollow framework to provide a stiff, lightweight structure; real birds use a hollow skeletal system for the same task.
The robot is guided by a handheld radio that controls its flight. Some of the funding for the Robo Raven was provided by the US Army Research Laboratory, which is investigating the Robo Raven's possible uses for surveillance and other missions.
The Robo Raven “attracts attention from birds in the area,†John Gerdes, an engineer at the Army's Aberdeen Proving Ground in Maryland, told Military.com.
Whereas seagulls and other birds try to fly in formation with the Robo Raven, raptors like hawks have tried to attack the bird as quarry.
"Generally, we don't see them coming," Gerdes said. "They will dive and attack by hitting the bird from above with their talons; then, they typically fly away."

Birds such as eagle and raptor are famous for their keen eyesight.
However, the researchers have created a robot bird so realistic, it even went on as a hawk, it swooped down and attacked them in a way that treated other pigeonlike birds.
Developed at the Maryland Robot Center, Robot & Mdash; known as Robot Crow & mdash; is made of carbon fiber; 3D printed, lightweight, heat resistant plastic; foam; and silver Mylar foil (its wings and tail), Military .com report. The outstanding bionic animal Image Gallery: Remarkable Bionic Animals was originally designed by the University of Maryland professors SK Gupta and Hugh Brook, who developed the battery-powered bird that was carried before the current model through several changes.
Long preparation time is necessary because any errors can cause the system to crash during the pilot-to-improve machine-neighbor-error process. This sometimes destroys the robot, so every step in the design process is extremely slow.
What makes the current model so realistic is that it can move independently of each other wing, just like the real bird's ability. This makes the robot crows sneak in, flying into the sky, dive and fan its wings than the old models, its wings can only move at the same time.
U0026 A more aerobatic way; our new robot, the robot crow, is based on a new design concept, said Gupta at a press conference. It uses two programmable motors that can be electrically synchronized to coordinate the movement between the wings
Some of the improved robot crows are inspired by the natural design. For example, the robot uses a hollow frame to provide a rigid, lightweight structure; the true bones used by birds to perform the same task.
By controlling its flying handheld radio-guided robot. Some of the funds for robotic crows are funded by the US Army Research Laboratory, which is investigating the requirements of the robotic crow; S possible use monitoring and other tasks.
The robotic crow draws attention from birds in the area, with John J., an engineer in the military's overall situation; Aberdeen at the Maryland test site, told Military.com.
While seagulls and other birds try to form a quarry with robotic crows, like the Eagle Raptors try to attack the birds.
In general, we can't see them coming, Jez said. They will dive and attack the birds from above with their claws; then they usually fly away
This project Gannan quality navel orange whole fruit (not peeled) as raw materials, using self-developed patent Orange surface sterilization technology to maximize retained a whole pieces of all Orange essence (Orange: Shun Qi, phlegm, pulp: fiber laxative, fruit seeds: allergic inflammation, juice: whitening detox).
Conventional enzyme production is mainly produced by hand, hand-sliced, hand-fermentation, the company every step of the process are used self-developed technology and equipment to automate production. Moreover, the conventional enzyme production have adopted a fermentation technology, enzyme often taste discomfort, sour and other issues, I produced using a variety of enzymes, probiotics composite grade fermentation technology, fermentation at different times with different strains, and two or three times through fermentation, enzymes such pure taste, streptozotocin balanced nutrients. Scientific and standardized process:
I produced using enzymes navel cleaning, sterilization, slice, fermentation (fermentation grade composite multi-strain), solid-liquid separation, bottling and other steps. Each step developed a patented automated production equipment, fully automated production, to avoid the traditional manual production workers are not standardized, easy to pollution, low production efficiency, product quality is unstable defects.
Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
