Watching a pair of robots 3D print an object is like gazing into the future

3D printing is one of the most exciting revolutions to hit manufacturing in decades, but it’s not without its limitations. Perhaps the biggest of these is the fact that, unless you create an unusually large 3D printer or break your model up into a whole lot of pieces, it’s difficult to create especially large 3D-printed objects. Fortunately, researchers from Singapore’s Nanyang Technological University have come up with a neat fix to the problem — and like all the best solutions, it involves a pair of robot arms.

In a new video demo, shown above, the researchers showcased how robots can build objects of virtually any size by moving around to carry out the printing. The demonstration employed off-the-shelf components, augmented by a nozzle, couplings, printing material and — perhaps most importantly — special guidance software developed at the university. It hints at a future in which whole teams of moving robots could collaborate to build structures.

“What we are seeing [in the video] is two mobile robots concurrently printing a concrete structure,” Pham Quang Cuong, Assistant professor of Mechanical and Aerospace Engineering at Nanyang Technological University, told Digital Trends. “The two robots first navigate from their base station to the printing site, then print by depositing a special type of cement layer by layer in a coordinated manner, and finally return to their base stations. The whole sequence was performed autonomously, [with] no human teleoperation.”

Cuong is no stranger to coming up with innovative uses for robots in construction tasks. Earlier this year, we wrote about another project he worked on in which robot arms were used to autonomously assemble a flat-packed Ikea chair — without having a massive argument over whether the instructions were being properly followed.

“The main potential use [for this latest project] is to print architectural, non-structural components, such as facades, either on-site or off-site,” he said. “Another team from our research center, the Singapore Center for 3D Printing, recently printed a bathroom unit using a similar technique.”

A paper describing the work, titled “Large-scale 3D Printing by a Team of Mobile Robots,” was recently published in the journal Automation in Construction.

Qualcomm’s push against Intel worked, and we’re all reaping the benefits

The idea of a processor company truly challenging Intel still feels far-fetched. Despite the repeated security mistakes and executive switch-ups, Intel has an almost unshakable reputation in the eyes of both manufacturers and everyday people. We see Intel, and we buy.

But if the Intel’s most recent set of chips is any indication, Qualcomm recent run of PCs has caught the attention of the Intel empire. For the first time in a long time, Intel was forced to play catch up.

Catching up on battery life

We were rightfully skeptical when Qualcomm announced its big push into the PC space last fall. Despite the experience the company had in the mobile space, powering a PC running Windows 10 was a different ballgame. We assumed the Qualcomm processors would struggle to offer a smooth experience, that that assumption proved true — but Qualcomm managed to pull off things Intel couldn’t.

Let’s start with battery life. This is a common pain point for laptops, and despite the push for all-day battery led by Apple a few years back, there hasn’t been much  forward momentum since. Then came the three laptops powered by the Qualcomm Snapdragon 845, each claiming twenty hours of battery life.

The battery doesn’t last that long in the real world (manufacture estimates are always a stretch),  but we were pleasantly surprised all the same. The Asus NovaGo, the most affordable of the trio, lasted over 15 hours in video playback, and over 10 and a half hours in web browsing. That’s not 20 hours, but it still beats the snot out a typical Intel-powered laptop running Windows 10.

Now, Intel has made that same push for battery life. Laptops announced this week at IFA with Intel’s new Core processors feature similar claims of around twenty hours of battery life. Outside of the Surface Book 2 (which had the bonus of an extra battery built into the display), we’ve never seen an Intel-powered PC with that kind of battery life. 

Tearing down the walls of connectivity

Connectivity is the second big innovation in Qualcomm-powered PCs. As you might expect given its roots in smartphone hardware, laptops with Qualcomm processors come with 4G LTE by default. While they aren’t the first laptops to feature this kind of connectivity, it was uncommon and sold at a hefty premium. These Qualcomm PCs are affordable, mainstream devices that can be used anywhere you’d use a smartphone.

Intel is making a similar push in connectivity with its chips. Laptops powered by Intel’s new round of U-Series processors feature Gigabit Wi-Fi. According to Intel, this will let people “download their favorite shows and movies in under a minute, create, edit, and share 4K/360 video content 6.5x faster, and stream and play games, including World of Warcraft: Battle for Azeroth and World of Tanks.”

The Y-Series processors, which are being implemented in lighter, more portable laptops like the 12-inch MacBook and XPS 13 2-in-1, go a step further. These processors will come with built-in 4G LTE, just like the Qualcomm devices. We just may see a LTE-enabled MacBook before the end of the year, for all we know.

That’s proof Intel is paying careful attention to its new rival, and adjusting accordingly. We even know Microsoft had every intention of making its Surface Go 2-in-1 into a Qualcomm device before Intel stepped in. 

Which begs the question…would we have ever seen this push from Intel, if Qualcomm hadn’t done it first? We may never know the answer. For now, let’s enjoy the benefits of some good, old-fashioned competition.

Looking for a wider screen? These are the best monitors of IFA 2018

Whether you’re a consumer looking to upgrade to a high-resolution display or a gamer seeking out the fastest refresh rates, IFA 2018 brought a number of eye-pleasing options. Many of the affordable monitors start with FHD resolution panels, but if you’re looking to step up your desk game, there are plenty of attractive choices that ship with higher resolutions, wider screens, and faster refresh rates.

All the monitors we saw checked off many of the boxes that consumers should look for when choosing to upgrade, including bright screens, slim bezels, and attractive styling. Displays designed with slim bezels not only take up less space and look more modern on your desk, but it’s also easier to connect multiple monitors together for an immersive computing or gaming experience without the screen’s borders getting in the way. But if you’re looking for a simpler setup, you may want to take a look at ultrawide monitors. These displays give you plenty of screen real estate on which to multitask without requiring you to connect multiple monitors.

Dell Ultrathin S2718DC

Who’s it for: Consumers who demand premium styling

How much and when can you buy it: Starting at $550 on September 20

If you don’t need an ultra high definition (UHD) panel, Dell’s Ultrathin S2718DC is one of the best-looking monitors to hit the market. As a technologically functional “objet d’art,” the Ultrathin S271DC measures less than a quarter-inch thick and comes with a near bezel-freedesign, 60Hz refresh rate, and a maximum resolution of 2,560 x 1,440 pixels. With 600 nits of peak brightness and HDR 600 certification, the Ultrathin is great for both work and entertainment.

If you’re running low on desk space, you can use the VESA-compatible mount to hang the monitor on a wall. To complement the design, the single USB-C connector helps to minimize unsightly wires snaking around your workspace, allowing you to power the display and connect to a compatible PC or laptop with one cable. Older computers can connect via the HDMI 2.0, and there’s a USB hub and a 3.5mm headphone jack on board.

LG UltraGear 34GK950G, 34GK950F

Who’s it for: Gamers who don’t want multiple monitors for an immersive experience

How much and when can you buy it: TBA

Even though it may be nice to connect multiple displays together, you can opt for a simpler single monitor setup and still get an immersive gaming experience with an ultrawide panel. LG’s pair of monitors support either Nvidia’s G-Sync technology (34GK950G) or AMD’s FreeSync tech (34GK950F) on a 34-inch panel. The pair comes with a 21:9 aspect ratio, and because it’s so wide, the display has a 1,900R curvature to help make it easier for your peripheral vision.

The ultrawide QHD resolution supports 3,440 x 1,440 pixels, and the panel supports 98 percent of the wide color gamut space. Refresh rates vary, with a 100Hz standard rate on the Nvidia-compatible panel that goes up to 120Hz when overclocked to a native 144Hz rate on the AMD-optimized screen. The panel comes with 400 nits of brightness and supports 5ms response time for gaming. In addition to faster refresh rates, the FreeSync panel also comes with HDR 400 certification and 1ms Motion Blur Reduction (MBR), whereas the G-Sync one doesn’t. Both panels can be mounted on a wall to save space, but gamers opting for the G-Sync variant will likely want to show off the backside of the display, as that version supports LG’s Sphere Lighting System for illumination.

Acer Predator XB273K and Nitro XV273K

Who’s it for: GeForce gamers not willing to sacrifice on specs

How much and when can you buy it: $1,299 (Predator), $899 (Nitro) in the fourth quarter

Though it will cost you a pretty penny, Acer’s Predator monitor delivers on the company’s gaming creds. Launched just in time for Nvidia’s newest GeForce RTX 2080 GPU, the Predator XB273K was designed for GeForce gamers. The panel takes advantage of the chipmaker’s G-Sync technology to prevent screen tearing. Gamers who play fast action games will love the 27-inch 4K UHD panel with a fast 144Hz refresh rate. HDR 400 certification helps you spot enemies or pick out details in shadows in games, and the display’s calibrated panel supports 90 percent of the wide color gamut. The Predator comes with an ErgoStand and a hood to help keep gamers focused, but if you’ve got a gaming chair — like Acer’s Predator Thronos chair — you can opt to mount the display with the VESA-compatible mount to create an immersive multi-monitor setup that will be the envy of your gaming pals.

Just because the Predator monitor was built to support Nvidia gamers doesn’t mean that Acer is turning its back on fans of AMD. The flagship Nitro XV272K matches the Predator XB273K spec-for-spec.. The main difference between the Nitro XV272K and the Predator-branded display is that the Nitro supports AMD’s FreeSync technology to prevent screen tearing. The Nitro XV272K also supports a fast 1ms moving picture response time (MPRT) for fast action games, and it features six-axis color adjustments, so gamers can tune the color, hue, and saturation on the display. The built-in black boost option allows gamers to select from 11 levels of black to gain a visual advantage when trying to spot enemies in darker scenes.

Samsung CJ79

Who’s it for: Tech-forward multitaskers wanting a premium experience

How much and when can you buy it: TBA

Stylish and chic, the Samsung CJ79 is an ultrawide monitor that doesn’t skimp on technology. Like LG’s UltraGear, Samsung opted to go with a curved 34-inch ultrawide panel on the CJ79. The CJ79 has a 1,500R curvature and ultrawide QHD resolution. Though Samsung is mainly targeting the CJ79 at creatives and professionals with this stylish monitor, gamers can also take advantage of the CJ79’s FreeSync support. The quantum dot LED (QLED) screen tech supports 125 percent of the sRGB space and has a 3,000:1 contrast ratio.

As the first monitor on the market to take advantage of Thunderbolt 3, you can use a single Thunderbolt cable for power, data, and video. Compared to USB-C, Thunderbolt 3 offers faster data throughput and outputs more power.  Older computers can rely on HDMI or DisplayPort, and the CJ79 also has a USB hub with three USB-C and two USB 3.0 ports to easily connect peripherals and accessories. Picture-in-picture support coupled with the ultrawide aspect ratio will be appreciated by multitaskers hoping to keep multiple windows open. If 34 inches is too small, Samsung also has a larger 43-inch CJ79 model with a 3,840 x 1,200 resolution and 32:10 aspect ratio. That monitor comes with an integrated KVM switch, allowing you to connect two computers to it.

Jane Krakowski to Star Alongside Hailee Steinfeld in Apple’s Upcoming Emily Dickinson TV Show

Jane Krakowski, known for her roles in “Unbreakable Kimmy Schmidt” and “30 Rock,” has joined the cast of Apple’s upcoming “Dickinson” series, reports Variety.

“Dickinson,” which Apple ordered back in May, is a half-hour show about the life of poet Emily Dickinson, who will be played by Hailee Steinfeld.

Also a musician, Steinfeld is known for her roles in “True Grit,” “Pitch Perfect 2,” “Pitch Perfect 3,” “Ender’s Game,” and coming of age film “Edge of Seventeen.”

Krakowski is joining “Dickinson” to play Mrs. Dickinson, Emily’s mother. In addition to “Unbreakable Kimmy Schmidt” and “30 Rock,” Krakowski has also worked on “Ally McBeal, “Alfie,” “Ice Age,” and “National Lampoon’s Vacation.”

“Dickinson” has been described as a comedic look into Emily Dickinson’s world that explores the constraints of society, gender, and family from the perspective of a budding writer who doesn’t fit into her own time.

For those unfamiliar with Emily Dickinson, she was a prolific American poet known for short lines, slant rhymes, and irregular use of punctuation. Much of her work focused on death and immortality, and she was known for living a reclusive life.

The show is being written and executive produced by Alena Smith, who was previously a writer on “The Affair” and “The Newsroom.” David Gordon Green, known for “Stronger,” Red Oaks,” “Vice Principals,” and “Pineapple Express” will direct.

“Dickinson” is just one of more than a dozen television shows Apple has in the works. Several of the shows are now in the casting stages, including an untitled space drama from Ronald D. Moore that will star Joel Kinnaman, “Are You Sleeping” starring Octavia Spencer, world-building drama “See” that will star Jason Momoa, and a series based on child journalist Hilde Lysiak starring Brooklynn Prince.

Rumors have suggested that we’ll see the first of Apple’s television shows debut in March 2019. It’s not yet entirely clear how Apple plans to distribute the TV shows, but given the sheer number of different shows in the works, it’s likely Apple plans to introduce a new streaming service based on its original content.

According to a June report from The Information Apple is considering building a bundle that would include access to original TV content, Apple Music, and news and digital magazines for one monthly fee.

Square Upgrades Square Reader for Magstripe With Lightning Connector

Square today announced that it has updated its original free Square Reader for Magstripe with a new Lightning connector, so sellers with the iPhone 7 and above will no longer need to use an adapter to accept payments from customers.

Prior to the Lighting connector update, the Square Reader plugged into the headphone jack on a device. Square users with the iPhone 7 or later were required to use an adapter with the Square Reader as Apple eliminated the headphone jack starting with the iPhone 7.

Square is also introducing support for using the original Square Reader with a computer using the Square Virtual Terminal. This setup is ideal for sellers who do the majority of their business on the computer, and the software is compatible with Apple’s Macs and Chromebooks.

According to Square, users will need to plug the Square reader for Magstripe into the headphone jack on a computer and then open up the Virtual Terminal to begin accepting payments via computer.

Transactions made via the new Square Reader with Lightning or the Square Reader used with a computer incur a 2.75 percent fee per swipe for Visa, Mastercard, Discover, and American Express. Manually entered computer payments incur a fee of 3.5 percent plus 15 cents.

The Square Reader for Magstripe with the new Lightning connector is available from the Square website for $10 or free for eligible merchants.

It flies and floats! The Spry drone wants to master both the sky and sea

The Spry looks like a typical quadcopter — until you flip it upside-down and toss it in the water. Designed by waterproof drone company SwellPro and Urban Drones, the Spry can navigate both in the air and in water with its (also waterproof) controller. Launching on Kickstarter and fully funded in a day, the Spry crosses both aerial and aquatic categories.

The Spry and its controller float in the water, allowing the drone to take off and land in water. Flip the drone over, and the props can help the drone navigate the water, though the company hasn’t yet detailed how fast or how long the drone can maneuver like a boat. While the company has launched air-to-water drones before like the Splash 3, the company says the Spry is the first that can also temporarily navigate underwater like a submarine using the propellers. (once the propellers stop, the floating drone returns to the surface).

In the air, the Spry is a mix between a racing drone and a camera drone. The drone uses a 4K 30fps camera with 12-megapixel stills, but with the GPS disabled, the drone can hit top speeds of more than 43 mph. With the GPS, the drone offers flight patterns like auto follow and object orbit, along with options like returning to the pilot’s position and holding the drone’s position in the air. The mobile app also allows pilots to pre-set a flight path using waypoints.

The camera sensor is from Sony, using the 1/2.3-inch size common in basic point-and-shoots. Controlling the camera from the remote control, the pilot can also tilt the camera to adjust the view from float to fly.

The included controller is also waterproof and floats, integrating a 4.3-inch monitor for live video. The drone’s Wi-Fi allows for streaming the footage to multiple devices at once, the company says, including optional flight goggles.

“The Spry’s ability to submerge under water and fly in the air makes it the most versatile drone ever created. We’ve only seen this in science-fiction movies,” Alex Rodriguez, Urban Drones CEO, said in a statement.

While the water-to-air design is unusual, the drone uses only a vertical axis gimbal mixed with electronic stabilization — there is some noticeable wobble to the sample footage shared by the company. Full specs on how long the drone can move on water — and underwater — also aren’t yet available. And while the Kickstarter is fully funded, there is always a potential risk with crowdfunded projects.

If the project is successful, early backers could pick up the drone for about $770; the company expects the retail price to be about $990. The company anticipates delivering the drones in December.

Next-gen A.I. hearing aid can translate languages, track fitness, monitor falls

We’ve covered some seriously impressive accessibility devices here at Digital Trends, but in most cases, they’ve all got one major limitation: They’re only trying to restore a certain function to the level that you’d expect in someone without a particular disability. That’s utterly commendable, but with modern technology, it’s sometimes possible to go further than this — to actually try and raise certain senses or functions beyond what you might normally expect to find.

That’s definitely the case for a smart new hearing aid from Starkey Hearing Technologies. With its newly launched Livio A.I. device, the company is reinventing the humble hearing aid for the machine learning generation. Not only does the Livio hearing aid enhance your ability to hear things, but it can also automatically translate foreign languages, and even track physical and mental well-being. Think of it like the babelfish from The Hitchhiker’s Guide to the Galaxy — only with some extra cool tech thrown in there for good measure!

“I believe Livio A.I. heralds the hearing industry’s iPhone moment,” Dr. Achin Bhowmik, Starkey’s chief technology officer, told Digital Trends. “The mobile phones prior to the iPhone were single-purpose devices, allowing us to make phone calls. In contrast, today’s smartphones are multipurpose devices. Hearing aids have so far been single-purpose devices as well, helping people hear better by amplifying sound. We are changing that with Livio A.I. With embedded sensors and artificial intelligence, we are turning the hearing aid into a multifunction health-monitoring and multiuse device that will help us lead better lives in many more ways. This is driven by our mission to improve human lives through technology.”

The next-gen hearing aid can translate between 27 languages, courtesy of a companion smartphone app called Thrive. If an English speaker says something they wish to translate, the words will appear in the selected target language on their mobile device so they can show the other person. If, on the other hand, a person says something in a language the wearer doesn’t speak, the words will be directly translated into spoken English via the earpiece.

The device also offers step-counting features, the ability to quantify your “brain score” based on active listening and social engagement, and smart gestures that allow wearers to control the audio stream from a TV by double-tapping their ear, rather than having to stop and search for the remote.

In the near future, Bhowmik said, the hearing aid will also be able to automatically detect if the user falls down using its in-built sensors. If a fall is detected, the hearing aid will then immediately notify designated emergency contacts by sending alert messages.

Watch as engineers 3D print a bionic eye prototype

University of Minnesota, McAlpine Group

At the beginning of 2015, Ray Flynn couldn’t see a thing in front of him. The 80-year-old suffered from a common disease called dry age-related macular degeneration (AMD), which caused him to lose his central line of sight and required him to rely on his peripheral vision instead. Flynn couldn’t use ATMs and had trouble distinguishing weeds from flowers in his garden. But in June, Flynn received the world’s first retinal implant to treat AMD, a procedure that left the patient with a bonafide bionic eye.

Now, engineers from the University of Minnesota have made another significant step in the development of bionic eyes. In a paper published this week in the journal Advanced Materials, the researchers describe how they 3D printed a prototype for a synthetic eyeball, equipped with photodetectors that allow the device to pick up light. The prototype could help usher in more advanced devices for visually impaired people.

“Here we demonstrate a fully 3D-printed hemispherical photodetector array that can sensitively detect images with a wide field-of-view,” Ruitao Su, a research assistant at the University of Minnesota who worked on the project, told Digital Trends. “The high efficiency of the photodetectors and the ability to readily customize the size and layout of the design render this approach … promising for the creation of bionic eyes.”

To make the device, the researchers began with a hemispherical glass cone, which they used as a sort of canvass to 3D print an array of photodetectors. Silver nanoparticles were used as conductive interconnections, and a couple layers of semiconductive components helped convert light into electricity. Finally, liquid metal was used to print cathodes on top. The whole process, which took about an hour, is pretty complicated but still generates a relatively primitive prototype.

Ideally, the researchers want to be able to print on a soft material, such as tissue, that can be implanted into a real eye. That means they have a lot of work ahead. Their next steps will include scaling down the size and improving the performance of their 3D-printed photodetectors, such that they can compete with commercial ones, and develop the image sensors to support a comprehensive vision system.
