Researchers Build Flying Robot

Researchers say they have assembled a flying robot. It’s not designed to fly like a bird or an insect, but was built to simulate the movements of a swimming jellyfish.

Scientists at New York University say they built the small, flying vehicle to move like the boneless, pulsating, water-dwelling jellyfish.

Leif Ristroph, a post-doctoral student at NYU and a lead researcher on the project, explained that previous flying robots were based on the flight of birds or insects, such as flies.

Last spring, for example, Harvard University researchers announced that they had built an insect-like robot that flies by flapping its wings. The flying robot is so small it has about 1/30th the weight of a U.S. penny.

Before the Harvard work was announced, researchers at the University of Sheffield and the University of Sussex in England worked together to study thebrains of honey bees in an attempt to build an autonomous flying robot.

By creating models of the systems in a bee’s brain that control vision and sense of smell, scientists hope to build a robot that would be able to sense and act as autonomously as a bee.

The problem with those designs, though, is that the flapping wing of a fly is inherently unstable, Ristroph noted.

“To stay in flight and to maneuver, a fly must constantly monitor its environment to sense every gust of wind or approaching predator, adjusting its flying motion to respond within fractions of a second,” Ristroph said. “To recreate that sort of complex control in a mechanical device — and to squeeze it into a small robotic frame — is extremely difficult.”

To get beyond those challenges, Ristroph built a prototype robot that is 8 centimeters wide and weighs two grams. The robot flies by flapping four wings arranged like petals on a flower that pulsate up and down, resembling the flying motion of a moth.

The machine, according to NYU, can hover and fly in a particular direction.

There is more work still to be done. Ristroph reported that his prototype doesn’t have a battery but is attached to an external power source. It also can’t steer, either autonomously or via remote control.

3D Printer Goes Retail

MakerBot, a 3D printer maker which opened two new retail stores last week, is among the companies trying to bring the cutting-edge digital manufacturing technology to Main Street consumers, but skeptics say the debut may be premature.

MakerBot, a unit of Stratasys Ltd, opened retail stores this week in Boston and in Greenwich, Connecticut, both of which are twice the size of MakerBot’s first store, 1,500 square feet in downtown Manhattan.

The company offers designs for more than 100,000 items through its “Thingiverse” online user community. The products range from knick-knacks like zombie sculptures to jewelry, sink drains and even medical devices. They are printed using its line of corn-based plastic fibers in more than a dozen colors.

“For most people 3D printing is futuristic science fiction. We’re here to make it real,” said CEO Bre Pettis, who cut the ribbon at the store on Boston’s fashionable Newbury Street using scissors made on one of MakerBot’s Replicator printers which start at $2,199.

Pettis, who has purchased splashy magazine ads to promote 3D printers as holiday gifts, believes there could soon be a 3D printer on every block in America.

Yet some technology experts say 3D printers may not be ready for prime time because they are still much less user friendly than most modern consumer electronics.

“There is so much hype,” said Pete Basiliere, an analyst at technology research firm Gartner. “People are getting a little bit misled as to how easy it is,” he said.

Some investors also are skeptical of 3D printing’s readiness for the market. Short-seller Citron this week published an article questioning the earnings of Germany’s voxeljet AG’s, and shares in the sector fell, including those of MakerBot parent Stratasys and rivals 3D Systems Corp and ExOne Co.

Twitter Tightens Security

Twitter Inc said it has put in place a security technology that makes it harder to spy on its users and called on other Internet firms to do the same, as Web providers look to thwart spying by government intelligence agencies.

The online messaging service, which began scrambling communications in 2011 using traditional HTTPS encryption, said on Friday it has added an advanced layer of protection for HTTPS known as “forward secrecy.”

“A year and a half ago, Twitter was first served completely over HTTPS,” the company said in a blog posting. “Since then, it has become clearer and clearer how important that step was to protecting our users’ privacy.”

Twitter’s move is the latest response from U.S. Internet firms following disclosures by former spy agency contractor Edward Snowden about widespread, classified U.S. government surveillance programs.

Facebook Inc, Google Inc, Microsoft Corp and Yahoo Inc have publicly complained that the government does not let them disclose data collection efforts. Some have adopted new privacy technologies to better secure user data.

Forward secrecy prevents attackers from exploiting one potential weakness in HTTPS, which is that large quantities of data can be unscrambled if spies are able to steal a single private “key” that is then used to encrypt all the data, said Dan Kaminsky, a well-known Internet security expert.

The more advanced technique repeatedly creates individual keys as new communications sessions are opened, making it impossible to use a master key to decrypt them, Kaminsky said.

“It is a good thing to do,” he said. “I’m glad this is the direction the industry is taking.”

Intel Buys KNO Software

Intel has acquired educational software developer Kno to add to its Education division.

Speaking in the company blog, Intel Sales and Marketing Group VP John Galvin explained that in a world where kids are being bombarded by technology, Intel Education has a mission to support the rollout of technology in the classroom.

Galvin said, “The Kno platform provides administrators and teachers with the tools they need to easily assign, manage and monitor their digital learning content and assessments.”

This acquisition brings Intel’s global digital content library to over 225,000 [higher education] and K-12 titles from 74 education publishers. “We’re looking forward to combining our expertise with Kno’s rich content so that together, we can help teachers create classroom environments and personalized learning experiences that lead to student success,” Galvin added.

Intel Education has been working for the past decade with over 10 million teachers that it has assisted to integrate technology with education.

In the UK alone there have been tremendous strides in educational software over the past 30 years, dating back to the government pledge to provide a computer in every school, which led to the creation of the BBC Microcomputer designed specifically for that purpose.

Today, not only is ICT a dedicated lesson in its own right, but it forms one of the key skills that educators are expected to incorporate into all lesson plans, putting it on a par with English and Maths, showing just how far we’ve come from making Venn diagrams with ascii art.

Intel’s Bay Trail M Is On The Way

Intel launched its Bay Trail-M ultra low voltage processors for netbooks and mobile devices over the weekend. According to CPU World the new mobile CPUs, branded this time as Celeron and Pentium, can manage twice the CPU performance, and up to three times faster graphics.

They do all that while using the same amount of juice as their “Cedar Trail” predecessors. Most chips have higher clock speeds than N2805, N2810 and N2910 SKUs and come with Burst Performance technology. They can operate at a higher maximum operating temperature which makes them easier to cool. Finally, in addition to 4 N28xx/N29xx Celerons Intel also released Pentium N2920.

Then there are new dual-core Bay Trail-M microprocessors like the Celeron N2806, N2815 and N2820 which can operate at frequencies from 1.6 GHz to 2.13 GHz, when going downhill had the wind is behind them. They also have the maximum burst speed ranging from 2 GHz to 2.39 GHz. The processors come with 1 MB L2 cache, Ivy Bridge graphics clocked at 311 MHz and up to 756 MHz, and support for DDR3L-1066 memory. The N2806 has 4.5 Watt TDP while the N2815 and N2820 have 7.5 Watt TDP. All of the Celeron N28xx processors are priced at $132.

Two new quad-core microprocessors are Celeron N2920 and Pentium N3520. The CPUs have 2 MB L2 cache, and run at 1.86 GHz and 2.17 GHz respectively, with burst frequencies reaching 2 GHz and 2.42 GHz. Both parts integrate Ivy Bridge graphics, that can be clocked as high as 854 MHz. The Celeron can deal with DDR3L-1066 memory, and the Pentium supports 1333 MHz memory data rate. They fit into 7.5 Watt power envelope. The official prices of Celeron N2920 and Pentium N3520 are $132 and $180.

Will nVidia’s Tegra 5 Go LTE?

The tradition continues. Our sources are confirming that Nvidia’s Logan SoC, possibly called Tegra 5, doesn’t come with an integrated LTE modem. Just like Apple, Nvidia makes a big fast chip with impressive Kepler based GPU, but it won’t put a an icera LTE solution inside the same chip.

Icera i500 is Tegra 5 compatible and it has AT&T certification. As the launch draws near, it should become compatible with other US and international LTE carriers like Verizon and T-mobile.

This should not be a big issue for Nvidia’s target market, manufacturers will have to choose two chips instead of one, a clear competitive disadvantage compared to future Qualcomm chips with Adreno 400 graphics and updated CPU cores, expected in early 2014.

During Nvidia’s recent conference call, CEO Jen Hsun Huang said devices based on the new Tegra 4i with integrated LTE should be announced in Q1 and ship no later than Q2. Jensen also mentioned that people are going to be “delighted by the OEM that it comes from” which is probably his way of of announcing some big brand design wins, but he also emphasised that the designs will be global rather than US. For US success you need CDMA Jensen said, but as far as we know Verizon is the only company using it.

Since Apple can pull of two chip designs from day one, we can only assume that two chip approach won’t cost much battery life compared to single chip design that has LTE on board (Snapdragon 600 and 800 ed. ). However, Nvidia is likely going to be making bets on its Kepler based GPU, expected to be the fastest graphics core ever integrated in a mobile SoC that will rock tablets and some phones around the world. The fact that Logan is likely to pack very powerful graphics sans on-die LTE makes it a bit more interesting for tablets than phones, which is exactly what we saw with the Tegra 4.

We expect to see Tegra 5 devices announced at CES 2014 so early January and with some luck we might see them shipping very early in 2014.

Can Acer Go High-End?

Most popular for its low-cost laptops, Acer doesn’t really inspire thoughts of premium products. But building high-end hardware could be the Taiwanese vendor’s best chance as it looks for a way to rescue its struggling business.

With consumers flocking to tablets and smartphones, Acer’s once-thriving PC business has been left in the dust. Quarterly financial losses have become routine at the company and its PC shipments declined more sharply in the past year than at any other major vendor, according to IDC.

The grim situation forced CEO J.T. Wang to resign from his post last Tuesday. Acer will also cut 7 percent of its global workforce and has assembled an advisory committee to come up with a new strategy, the company announced.

Bright spots are hard to find. The Wintel model that propelled Acer for years and helped it become the second-largest PC vendor in 2009 has been falling apart amid the demand for mobile gadgets. And Windows 8 and Intel’s Ultrabook strategy have failed to resuscitate the market.

It hasn’t helped that Acer is so reliant on sales to consumers, said IDC analyst Bryan Ma. The entire PC industry has been hurt by tablets, but Dell and Hewlett-Packard have at least managed to find cover selling PCs to businesses, which are still buying them. And Lenovo has capitalized on its position in China, now the world’s largest PC market.

“Acer didn’t really have the commercial PC business to protect themselves. That’s why they were hit harder,” Ma said.

Acer — whether to its benefit or detriment — has instead gained a reputation for low-priced PCs. Even in tablets it has tried to undercut rivals — its Iconia W4, an 8-inch Windows 8.1 tablet, starts at US$329.99, while its Iconia B Android tablet goes for $129.99. The low prices have helped keep the company on consumers’ radar, but at the expense of profits.

One option for Acer is to build a brand as a higher-end PC player. It took a step in that direction last year with the Aspire S7, a Windows laptop with a slender, aluminum chassis that sells for $1,200 and up. That product and its successors have had some success for the company, with sales of 2,000 to 3,000 units per month, said James Wang, an analyst with research firm Canalys.

“I think Acer has started to learn they are able to sell some expensive products,” he said.

Selling higher-end PCs could help stop the bleeding in Acer’s finances, but with the overall PC market still shrinking it’s unlikely to help it expand in any meaningful way. “You can’t really expect vendors in desktops and notebooks to find growth,” Wang said. “You win in the market by not falling in shipments.”

Can Robots Run On (NH2)2CO?

Scientists have discovered a way to power future robots using an unusual source — urine.

Researchers at the University of the West of England, Bristol and the University of Bristol collaborated to build a system that will enable robots to function without batteries or being plugged into an electrical outlet.

Based on the functioning of the human heart, the system is designed to pump urine into the robot’s “engine room,” converting the waste into electricity and enabling the robot to function completely on its own.

Scientists are hoping the system, which can hold 24.5 ml of urine, could be used to power future generations of robots, or what they’re calling EcoBots.

“In the city environment, they could re-charge using urine from urinals in public lavatories,” said Peter Walters, a researcher with the University of the West of England. “In rural environments, liquid waste effluent could be collected from farms.”

In the past 10 years, researchers have built four generations of EcoBots, each able to use microorganisms to digest the waste material and generate electricity from it, the university said.

Along with using human and animal urine, the robotic system also can create power by using rotten fruit and vegetables, dead flies, waste water and sludge.

Ioannis Ieropoulos, a scientist with the Bristol Robotics Laboratory, explained that the microorganisms work inside microbial fuel cells where they metabolize the organics, converting them into carbon dioxide and electricity.

Like the human heart, the robotic system works by using artificial muscles that compress a soft area in the center of the device, forcing fluid to be expelled through an outlet and delivered to the fuel cells. The artificial muscles then relax and go through the process again for the next cycle.

“The artificial heartbeat is mechanically simpler than a conventional electric motor-driven pump by virtue of the fact that it employs artificial muscle fibers to create the pumping action, rather than an electric motor, which is by comparison a more complex mechanical assembly,” Walter said.

Is Qualcomm’s Adreno 400 Coming in 2014?

Qualcomm’s Adreno 330 GPU will be replaced by new Adreno 400-series parts and naturally the new generation will be faster than the one that sits inside the Snapdragon 800.

Our sources are telling us that Adreno 400 is expected with the new version of Snapdragon that is set to debut in early 2014. Traditionally Qualcomm uses CES to showcase its new chips and CES 2014 starts on January 7th, so it sounds like the right time for it.

The only key detail that we learned about Adreno 400 is that despite a significant increase in GPU performance the chip won’t have a compute part and it doesn’t support OpenCL. Many will see this as a handicap, but to be honest we see limited uses for OpenCL in mobile chips, at least for now.

Nvidia’s Logan comes with Open CL 1.1 as well as Open GL 4.4 support. Adreno 330 can push 3.6 Gigapixels a second making it one of the fastest GPUs in mobile market, capable of going head to head with the Tegra 4. Adreno 400 naturally ends up faster.

Then again we expect that Logan Tegra 5 has what it takes to dominate the mobile GPU market in 2014. Let’s not forget about PowerVR 6-series parts, ARM’s recently announced Mali 700-series or Vivante’s upcoming mobile GPU designs, either.

Unlike the AMD-Nvidia duopoly in the PC GPU market, right now there are five players vying for the top spot in the mobile space and things are bound to get interesting.

Africa To Lead Global Bandwidth Demand

Africa’s demand for Internet access to the rest of the world will grow by an average of 51 percent every year until 2019, ahead of all other regions, according to a forecast by research company Telegeography.

Rapid economic growth and wider Internet use will drive the increase in demand, which will be met mostly by turning on unused capacity in existing cables, according to Telegeography analyst Erik Kreifeldt. Terrestrial links are in demand partly because much of Africa still relies on satellite, which is far more expensive per bit than wired broadband, he said.

Most Internet bandwidth between continents is provided by undersea cables built and financed by groups of service providers. From Africa, most of those links go to Europe. Other carriers pay to tap into those cables and link their customers to the Internet. In some parts of Africa, running cables from coastal areas to the interior is a challenge so satellite remains the major Internet source, Kreifeldt said.

The capacity of international cables landing on African shores is just a fraction of the bandwidth available between Europe, the U.S. and Asia. After seven years of the growth that Telegeography forecasts, from 2012 through 2019, Africa will have 17.2Tbps (bits per second) of links to the outside world. That’s up from just 957Gbps in 2012 but will still be only about one-quarter of the international capacity of Latin America and less than that of Canada, according to Telegeography.

The hunger for the Internet varies among African countries. Through 2019, bandwidth demand is expected to grow fastest in Angola, at 71 percent per year; Tanzania, at 68 percent; and Gabon, at 67 percent.

Many new cables have been built to Africa and around the continent in the past several years, giving service providers excess fiber capacity that can be turned on when needed, Kreifeldt said. As that fiber gets lit up and supply rises, prices should fall for enterprises and other users in African countries, he said. However, due to relative scarcity, a given amount of bandwidth between Africa and Europe costs about 10 times as much as the same size connection between Europe and North America, he said. Africa’s bandwidth gains aren’t expected to shrink that gap.
