Sensitive E-skin for Robots

That day is not so far when robots will be touchy and feely like humans. Robots that made from metal in human size can do multiple works. These robots look same as human and can do different kind of work, these robots will have now skin that identify sensitivity of skins.

Because of this skin, now modern robots will look exactly like human and while touching them they will make us to feel same sensitivity and softness just like human being. Researchers of California University had tried to make sensitive fingers of robot that can pick up the delicate drinking glass carefully.

They also made e-skin for such robots from in organic materials. For this they used germanium/silicon nanowires on a cylindrical drum, which was then rolled onto a sticky substrate. This e-skin is one kind of chip which is slimmer like rubber and it make robot to feel touch. This robot can carry a child and play with him without any harassment.

The substrate used was a polyimide film, but the technique could be used with a variety of materials, including other plastics, paper or glass, the team said. The nanowires were deposited by the drum onto the substrate in an orderly fashion, and then the substrate was processed into thin, flexible sheets.

For the e-skin, the engineers printed the nanowires onto an 18-by-19 pixel square matrix measuring 7 centimeters on each side. Each pixel contained a transistor made up of hundreds of semiconductor nanowires. Nanowire transistors were then integrated with a pressure sensitive rubber on top to provide the sensing functionality.

The matrix required less than 5 volts of power to operate and maintained its robustness after being subjected to more than 2,000 bending cycles.

The e-skin developed by the team can detect pressure from 1 to 15 kilopascals. That's about the amount of pressure used to complete daily activities like typing on a keyboard or holding an object, the researchers said.

Such sensitivity is necessary to create a human prosthetic hand that can distinguish between the force necessary to, say, hold an egg without cracking it and the force necessary to lift a heavy pot without dropping it.

Google has released its goo.gl URL shortener to the public

Google has released its goo.gl URL shortener to the public, and created a standalone website so that anyone can use the service to shorten and track the URLs they share via social media sites and e-mail.

The phrase “Google it” is getting a whole new meaning today; the search giant has just released its goo.gl URL shortener to the public and created a standalone website so that anyone can use Google to shorten and track the URLs they share via social media sites and e-mail.

Goo.gl initially debuted last December as a feature integrated into other Google () products. Google’s newly public URL shortener competes with a myriad of other popular services, Bit.ly () being the most notable of the bunch.

The company claims that its shortener boasts stability, security and speed. The former two are especially important as several other services have been plagued by both downtime and malicious parties masking deceptive links. Goo.gl features automatic spam detection, and “near 100% uptime since our initial launch,” according to the company’s announcement.

The product also comes with expected URL-tracking features. As a goo.gl user, you can log in to your Google account to view URL history, traffic sources, referrers and visitor profiles for countries, browsers and platforms.

Google is known to hide bonus easter egg features in its products, and goo.gl is no different. Earlier today, Google engineer Matt Cutts tweeted one such easter egg — add .qr to a shortened goo.gl URL and you’ll create a QR code that, when scanned, will redirect to the original URL. It’s a quirky additive that makes goo.gl all the more friendly for brands and marketers experimenting with QR codes. A Twitter () tipster also informed us that you can add .info to the goo.gl URL to check out analytics.

As for why Google is going public with goo.gl, it’s anybody’s guess. Initially, goo.gl was designed because the company didn’t want to rely on other URL shorteners for the same purpose. Our guess is that it’s another small part to the much speculated about social strategy. After all, Google is the business of URLs, and URLs are the fabric of the social web. What’s your take?

Cloud Burst, Cloud Computing

It’s the right season to go chasing clouds–in a manner of speaking. So we present the ‘seriously dumbed down guide to cloud’–the hottest term in computing
Ever so often, in your company’s IT department, you’ll hear someone say, “Why live in the desktop when you can live in the cloud?”
At this point, nobody is going to blame you if you wonder what the IT department has been smoking. It might pay to get on board though, tiresome as it may seem. After all, you just finished mastering “wet lease” and came to terms with “rainmaker”, and now there’s “cloud” to contend with. In the world of jargon, there’s never a drought, is there?
But the good news is that “cloud” and “cloud computing” are swiftly saturating, lurking in the corridor of every company that wants to bring down costs and be liberated from the “tyranny of the geeks”. In other words, IT departments are simply using the term—made sexy by Google’s Eric Schmidt in 2006 to describe his company’s approach to Software as a Service (SaaS)—in a bid to describe the client-server model (hang in there, we’ll translate this too, in just a moment).
Everyone’s cloud-surfing
To begin with, we’ll get rid of your chief anxiety-inducing question: What if I don’t use cloud? Am I a technological troglodyte?
Chances are really low that you are not already using cloud computing. If you use a Web-based email service (such as Hotmail, Yahoo, Google, GMX or Gawab), you are already using “cloud”. Congratulations.
But this might leave you scratching your head and asking, “So, what’s new then?” Well, what’s new is that cloud computing has now begun to radically change the IT business, transforming it for large and medium enterprises as well as for individuals such as you and me.
Assume you have a small business or run an NGO. Using a Web-based email service helps you do three invisible things: move the load of computing from your desktop or laptop to a machine owned by someone else on the Net; stop adding storage space or backup devices as the volume of your emails grows; and not purchase the software on which the email runs. Yes, as a business and as an individual, you are not buying software licences any more. And you are still on the right side of the law. How cool is that? Because anyone who runs a business is familiar with the nightmare of buying additional licensing as the workforce grows (for specifically business-related cloud computing services, see “Nine ways to live among the clouds”).
Even if you’re not a business owner or manager, but have used Facebook, MySpace, Twitter, Flickr, Photobucket, YouTube or Vimeo, you are a veteran cloud user. If you use Google Docs to store, share and collaborate on your documents, you have moved a step ahead on the cloud computing platform and qualify as an advanced user. And if you’ve begun to use Wikis for content management and collaboration, you are perhaps a cloud computing champ. In fact, you are qualified to use terms such as “distributed-access workspace” just to confound everyone and effectively keep competition anxious.
The SaaS syndrome
At this point, you may wish to describe cloud computing as “Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on demand, like electricity”. That’s the simple Wikipedia definition. Notice how it also carefully includes a rough-around-the-edges definition of SaaS.
When you put software on the Web and make it accessible to multiple people, you get SaaS. “Because SaaS can be designed to be modular and ‘pay-as-you-go’, it has become the hot option over software that you buy, own and keep paying licence fees for even when you are not using all the features of the package,” says Darshan Jadav, CEO of Pune-based Widget Factory Software, a decade-old company that has expertise in financial software and offers small and medium businesses with supply chain management capability in cloud.
Fundamentally, Widget Factory brings SAP-style resources to small firms in the area of pay, accounts, inventory management and control, HR management, business intelligence and reporting tools. What providers like Widget Factory enable for small and medium enterprises (SMEs) is the ability to use and pay for what they need, without having to worry about platforms, infrastructure, software upgrades, availability, backup and crashes. “Best of all,” points out Jadav, “they don’t need an IT team to run around managing complex technology. Cloud takes the headache out of computing.”
It’s raining convenience
What cloud does is reduce start-up costs for enterprises by bringing down investments in hardware, controlling spiralling software and hardware upgrade outlays and shrinking IT maintenance crews.
But what does it do for you and me?
To begin with, thanks to cloud computing, you can work from anywhere and access your data even when you are not on your own computer. Your data and software applications are available to you regardless of where you are, as long as you can log on to the Internet.
Besides, with your data living in cloud, you become machine-independent—whether you have a PC or a Mac at your disposal, you can access your data just by opening a browser.
So if your computer crashes you needn’t worry about your data—just move to the next terminal and continue working. A few months ago, Vishal Bali, the CEO of the Wockhardt Hospitals group, lost his laptop. It wasn’t the hardware that he was worried about—he needed urgent access to data to continue with his meetings. Perhaps, if the data were maintained in cloud, there would have been a silver lining.
The dark cloud?
But there is probably good reason he didn’t put it there. Because cloud computing usage is also going through a serious reality check on the security front.
No one wants sensitive company data to sit on a computing grid that is shared by others—including the competition—unless it is secure. So the question is, what happens if your cloud computing provider’s systems are hacked or compromised? A June 2008 Gartner study, Assessing the Security Risks of Cloud Computing, said cloud computing had associated risks in the areas of data integrity, recovery, privacy and even legal issues such as regulatory compliances (for example, you may not be comfortable with local privacy laws where your data is being stored if it differs from your own country’s) and auditing. These issues are being addressed as standards are being developed by Cloud Security Alliance (www.cloudsecurityalliance.org) and other organizations.
Meanwhile, SMEs and individuals don’t need to get overly apprehensive. What large enterprises—and governments—are debating is somewhat similar to what we were wondering about a decade ago when we walked around with floppy disks: What if I lose the disk? We lived through that, right?
DRIVING A DIFFERENCE
Honestly, what’s so great about cloud computing? Here’s an off-the-beaten-path (but on the road) example to set you thinking.
You own a car. And you plan to keep it for the next 10 years. Aren’t you lucky the car does not have an onboard computer? Because if it did, the computer would be outdated in a couple of years. Which is why auto manufacturers are reluctant to install powerful computers on the dash, preferring to have simple things such as GPS devices there. But if you could install a device that accesses the computing power in a cloud, it would make for a killer app. The thrust here is on keeping it relevant through the life of your investment, since a car’s life spans 10-15 years on average. So, while the actual computing device would remain the same, the cloud computing power behind it could keep improving, providing the car with a value-for-money feature that you don’t have to pay to upgrade.
