Scientists ‘knit’ soft robotic wearables for easier design and fabrication

Scientists have made considerable progress with soft robots used for assistive wearables, rehabilitative technologies and more. Powered by compressed air, they offer advantages over regular robots like sensing capabilities, soft touch, and high power-to-input ratios. 

Designing and building them has been a challenge, however, due to the need for a manual design and fabrication pipeline that requires a lot of trial and error. Now, scientists from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have come up with a new pipeline called “PneuAct” that uses computers and a special knitting process to design and digitally fabricate the soft pneumatic actuators. Their work could eventually lead to new assistive and rehabilitative devices. 

“PneuAct uses a machine knitting process — not dissimilar to your grandma’s plastic needle knitting — but this machine operates autonomously,” according to CSAIL researchers. The designer simply needs to specify the stitch and sensor design patterns in software to program actuator movements, which can be simulated before printing. The textile piece is then fabricated by the knitting machine, which is fixed to a rubber silicone tube to complete the actuator. 

The actuators use conductive yarn for sensing so they can essentially “feel” or respond to what they grab. As proof of concept, the team developed several prototypes including an assistive glove, soft hand, interactive robot and a pneumatic walking quadruped, as shown in the video above. 

The new devices are considerably improved over older designs, incorporating programmed bending when inflated and the ability to incorporate feedback. “For example, the team used the actuators to build a robot that sensed when it was touched specifically by human hands, and reacted to that touch,” the team wrote. The glove could be worn to supplement finger muscle movement, adding extra force for grasping to help people with finger or hand injuries. 

The team plans to explore actuators with different shapes, and incorporate task-driven designs with target poses and optimal stitch patterns. “Our software tool is fast, easy to use, and it accurately previews users’ designs, allowing them to quickly iterate virtually while only needing to fabricate once,” said Harvard University’s Andrew Spielberg, an author on the paper. 

EU charges Apple over NFC payment restrictions on iOS devices

As the European Commission continues to look into whether Apple has abused its market dominance by restricting mobile payments on iOS devices, Executive Vice-President Margrethe Vestager today confirmed that it has formally charged the iPhone maker, which could result in a hefty fine if it is upheld.

In a statement, Vestager said that the Commission had “indications that Apple restricted third-party access to key technology necessary to develop rival mobile wallet solutions on Apple’s devices,” adding that the company “may have restricted competition, to the benefit of its own solution.”

Developers, the Commission argues in its Statement of Objections, have been barred from “accessing the necessary hardware and software” to create their own NFC payment services on Apple devices. Contactless payments are popular across Europe, but Apple Pay remains the only contactless option for in-store payments on iPhone and iPad.

“Apple Pay is only one of many options available to European consumers for making payments, and has ensured equal access to NFC while setting industry-leading standards for privacy and security,” Apple said in a statement. “We will continue to engage with the Commission to ensure European consumers have access to the payment option of their choice in a safe and secure environment.

The Commission opened a dual review into both Apple’s in-app and NFC payment systems in June 2020, noting that the company’s choice could stifle competition and therefore reduce consumer choice. The Commission says that today’s announcement relates only to the “NFC input by third-party developers of mobile wallets for payments in stores” and not online restrictions against or “refusals of access to Apple Pay” for competing services.

Apple has previously said that it limits third-party access to contactless payments in order to boost security. It claims that its own technology prevents fraudulent payments by using a secure chip inside the iPhone antenna. 

A Statement of Objections provides Apple with a list of exceptions that it argues go against EU antitrust rules. The company will now be invited to reply to the issues raised and request a meeting with officials, which means it could be some time before an official decision is reached.

Amazon’s Kindle e-readers are up to 41 percent off right now

Over the past few days, Amazon has begun slashing the price of its own gadgets as part of a wider Mother’s Day sale. Yesterday, we saw the Echo Show 8 and Echo Show 15 fall back to all-time lows, and today it’s the turn of the retailer’s popular Kindle e-readers, which are now offering savings of up to 41 percent.

Leading the way is the Kindle Paperwhite, which is typically priced at $140, but has fallen back to an all-time low of $105 in this particular sale. The standard Kindle is also down to $55, just $5 off its lowest ever price.

The fifth-gen Paperwhite, which was refreshed for the first time in three years this past September, has a larger screen than the previous model at 6.8 inches (compared to the six-inch display on its predecessor). Amazon says the 300 ppi screen looks like real paper and its glare-free screen enables “easy reading” in all conditions, even direct sunlight. Not only is it compact, but it has a waterproof design that will ensure it remains operational when splashed. There’s also support for USB-C fast charging.

If you’re looking for something a bit more premium, the Kindle Oasis is on sale too. The 8GB model, which typically costs $250, is currently available for $200. The e-reader has previously been as low as $175, so it’s not currently near its all-time low, but still offers $50 off its usual price. The Oasis features a 300 ppi display, though the screen is slightly larger than the Paperwhite at seven inches. It has physical page turn buttons, an IPX8 waterproof rating and a color-adjustable front light.

It may also be a good time to encourage your child’s love of reading. Amazon is selling the Kindle Paperwhite Kids for $120, or a full $40 below the usual price. The standard Kindle Kids is also on sale for today at $65 with a decent $45 (or 41 percent) discount. They both come with a two-year “worry-free guarantee,” a protective cover and a 12-month Kids+ subscription with access to thousands of books.

Apple’s 2021 iPad mini falls to a new all-time low of $400

Apple’s latest iPad mini has been on sale for a little under a year, but we’ve seen numerous price reductions on the (almost) pocketable slate. Having hovered around the $459 price point in recent times, Amazon has now discounted the 64GB iPad Mini further, bringing it down to a new all-time low of $400. That’s $99 off the original price or a savings of 20 percent.

If you’re looking for a bit more storage, Amazon has also reduced the 256GB model, which now costs $540. That means you’ll save $109 or 17 percent compared to the retailer’s list price.

The 2021 iPad mini received a score of 89 in our review, gaining marks for its “all-screen” design without the home button its predecessors have. It has a Liquid Retina 326ppi panel with a 2,266 x 1,488 resolution. The tablet’s edges are flat, and also sports a TouchID-capable power button, dropping the Lightning port for USB-C charging.

The slate features a new 12-megapixel ultra-wide front camera with Center Stage support, which like Facebook’s Portal devices will automatically pan and zoom to keep you at the center of the screen during video calls. 

Thanks to the A15 Bionic chip powering the tablet, it was also able to handle we threw at it. It typically lasts up to 12 hours between charges and it also supports the second-gen Apple Pencil so you can use it for doodling or note-taking while on the go.

Microsoft Edge will soon include a free built-in VPN

Microsoft has consistently tried to get more people to use Edge. Some of the ways it has pursued that goal have been less well-received than others, but its latest effort to do so could make for a useful addition to the software. In a support page spotted by The Verge, the company revealed it’s adding a free built-in VPN service dubbed Edge Secure Network to its web browser. 

The company says the tool will encrypt your internet connection. You can use that functionality to protect your data from your internet service provider. As with most VPNs, you can also use Edge Secure Network to mask your location, making it possible to access services that might otherwise be blocked in the country where you live or are visiting.

If you find yourself frequently traveling, chances are Edge Secure Network won’t replace a paid VPN. The feature limits you to 1GB of data usage per month. It’s also worth noting you’ll need a Microsoft account to use the service. Microsoft has yet to begin testing the VPN. But once the feature is available, you’ll be able to enable it through Edge’s three-dots icon. A new option titled “Secure Network” will turn the VPN on. Once you’re done browsing, it will automatically turn off again. 

Cat adventure game ‘Stray’ delayed to summer 2022

Cat aficionados will have to wait a bit longer to get their paws on Stray. Developer BlueTweleve Studio’s feline simulator won’t release in early 2022 as previously announced. It’s now slated to come out sometime this summer. Sony shared news of the delay in a tweet spotted by The Verge. “Releasing summer 2022,” says the video accompanying the message.

The clip includes footage from the gameplay walkthrough publisher Annapurna Interactive shared last summer. And if you’re curious what Stray is all about, that video provides a few clues. In it, we see the game’s feline protagonist explore a neon-soaked city populated by robots of all shapes and sizes. Gameplay involves using his abilities as a cat to solve environmental puzzles. Partway through your journey, you’ll meet B-12, a drone that will allow you to converse with the city’s inhabitants. Naturally, as the cat, you can also do things like scratch furniture and rub up against the legs of robots you meet.

Apple extends update deadline for outdated apps in danger of being deleted

Apple recently sent notices to some indie developers, warning them that their app will be pulled from the App Store if it’s not updated within 30 days. The tech giant has had a policy in place against outdated and abandoned applications since 2016, but the move suggests that it’s now more rigorously enforcing that rule. Some of the letters’ recipients criticized the policy for being a barrier to indie developers, what with how tough it is to keep up with platform changes and how much work it takes to roll out even a minor update. Now, Apple has published a post clarifying why some old apps are in danger of being removed, along with the announcement that it’s giving developers more time to update their applications. 

In the post, the company said that it will only send removal notices to developers whose apps haven’t been updated in three years, as well as to devs whose apps have not “been downloaded at all or extremely few times during a rolling 12 month period.” Apple said that dropping outdated apps makes newer ones more discoverable and also ensures users can enjoy games and tools that have been optimized for its latest OS and devices. 

As a lot of people know, there are older apps don’t work as well on the latest generation of phones, tablets and laptops anymore, delivering a subpar user experience. Still, 30 days might not be nowhere near enough time for smaller developers to conjure up an update. The good news is that Apple has extended its grace period and is now giving them up to 90 days to update their applications. Users will get to keep apps that are already installed on their devices even if they end up getting deleted, and developers can continue earning from them through microtransactions.
