SAN FRANCISCO Nike Shox R4 Nere Italia , May 26 (Xinhua) -- Roboticists at the University of California, Berkeley, have built a new robot that can pick up and move unfamiliar, real-world objects with a 99 percent success rate.
The dexterous robot, called DexNet 2.0, gained its highly accurate dexterity through a process called deep learning.
Irregularly shaped items such as shoes, spray bottles Nike Shox OZ D Uomo Nere Italia , open boxes, rubber duckies are easy for people to grab and pick up, but robots struggle with knowing where to apply a grip.
UC Berkeley professor Ken Goldberg, postdoctoral researcher Jeff Mahler and the Laboratory for Automation Science and Engineering (AUTOLAB) created DexNet 2.0 with the support of a vast database of three-dimensional shapes, 6.7 million data points in total, that a neural network uses to learn grasps, which in turn will pick up and move objects with irregular shapes.
The neural network was then connected to a 3D sensor and a robotic arm. When an object is placed in front of DexNet 2.0 Nike Shox Avenue Uomo Nere Italia , it quickly studies the shape and selects a grasp that will successfully pick up and move the object 99 percent of the time.
Featured as the cover story of the latest issues of MIT Technology Review, DexNet 2.0 is also three times faster than its previous version.
With such a high success rate, claimed UC Berkeley's Industrial Engineering and Operations Research Department in a news release. "it is likely that this work will soon be applied in industry, possibly revolutionizing manufacturing and the supply chain."
AUTOLAB at the public university in Northern California is a world-renowned center for research in robotics and automation sciences, with more than 30 postdoctoral researchers, doctoral and undergraduate students pursuing projects in Cloud Robotics, Deep Reinforcement Learning Nike Shox 807 Uomo Nere Italia , Learning from Demonstrations, Computer Assisted Surgery, Automated Manufacturing and New Media Artforms.

A city in China's water-rich Hubei province that has sacrificed much for China's grand south-north water diversion project Balenciaga Speed Trainer Italia , which has begun to supply water to China's arid north, has been called "the saddest city in China" by local officials, the news website thepaper reported Tuesday.
Despite its great contributions to the project, the city is still plagued with poverty. Many of its residents are moving their whole lives to make way for the project.
Over the past five decades, the city experienced two large-scale migrations. The first came in 1958 when Danjiangkou Reservoir Dams were built and the 2,000 year old city of Junzhou was totally submerged in 1967. Then, in 2009 Balenciaga Triple S Italia , Junxian town, a town that housed immigrants from Junzhou and named in the memory of that ancient city, had to relocate all its residents again because the dam was raised leading to higher water levels.

A city of reluctant migrants
Nearly two years ago, the entire Junxian town was relocated to a new site six kilometers away, to make way for the south-north water diversion project.
Ming Ruixiang, a 55-year-old resident, is an exception. She still lives in the original site of Junxian town due to relocation disputes.
This is far from the first time Ming faced relocation. As early as 1966 Nike Shox Avenue Uomo Italia , the then 7-year-old Ming moved from her hometown near Junzhou Ancient City with her parents. The migration did not end there. Without knowing the ultimate water level of the Danjiangkou Reservoir, her family has fallen into a vicious cycle of moving to a new place, being submerged by water and moving again, until they finally settled down in the original site of Junxian town. She cannot remember how many times she moved. The only certainty is that all the moves took place in the jurisdiction of one city, Danjiangkou.
Danjiangkou is the starting point of the middle route of south-north diversion project and its pride, Danjiangkou Reservoir, is the key water source of the project.
Danjiangkou city has undergone two large-scale migrations. The first migration happened when Danjiangkou Reservoir Dams started construction in 1958 and about 160 Nike Shox Avenue Italia ,000 residents moved. In 2005, Danjiangkou Reservoir Dams rose to 176.6 meters from 162 meters, submerging new areas. The second batch of up to 100,000 migrants were relocated after 2009.
For most Danjiangkou residents, moving has become a part of life due to the water diversion project. He Shengyou, a villager, relocated as many as six times Nike Shox 807 Italia , said Chen Huaping, deputy head of the information office of Danjiangkou city government.
On Nov 18, 1967, Danjiangkou Reservoir started to store water. Though unwilling to move, the next morning He Shengyou saw his house submerged by rising water and "many snakes and rats climbed to the rooftop of his house" to escape the flood.
An ancient city sleeps underwater
In the winter of 1965, the then 11-year-old Ding Lixian was brought by his father to see Danjiangkou Reservoir Dams under construction. Taking a boat upstream, Ding saw half of the demolished ancient city walls without a single soul in it.
