When Google introduced a new TV overlay last year, it promised to bring a modern interface to Chromecast and subsequently launched devices. It also caused a lot of confusion over what would happen to the Android TV operating system, which powers hundreds of models of streaming sticks, TV sets and more. Those older devices didn't get the new Google TV interface, but the company did begin to roll out some updates that made Android TV look more similar to the new layout, including a refreshed appearance and a Discover tab. Today, Google is adding new tools to Android TV to make it feel more like Google TV: Watchlist, recommendation tuning and detail pages.
With this update, you can now add titles to your watchlist across the Android TV system, either by long-pressing on your selection and hitting "Add to Watchlist" or pressing the Watchlist option in the show's detail page. You can also add to the list from your phone or laptop via Google Search or in the TV app. Your saved items will appear in a row on the Discover tab.
The company also tweaked the detail pages of each show by adding trailers that autoplay when you dive deeper into each title, similar to how services like Netflix are set up. You can turn these off in the Settings (under Home Screen in Device Preferences by deactivating "Enable video previews").
Google
You'll also find a new way to tell Google what shows you like (and hate) in the Home Screen settings — look for Content Preferences and scroll through the titles that show up. Additionally, there's a card in the Discover tab that says "Improve your recommendations" that will let you tune your preferences too, and you can choose between "More like this" or "Less like this" for each show. Once you're done, the system will update its suggestions for you in the Discover page.
Those already using a Chromecast with Google TV will find these features familiar, and those with older Android TV devices don't have to wait long to get them. Google said the updates will arrive on Android TV devices "beginning this week."
AT&T is set to provide voice, data and messaging services to Dish's Boost Mobile, Ting and Republic Wireless customers for the next 10 years. Dish plans to pay AT&T at least $5 billion as part of the deal, according to a filing with the Securities and Exchange Commission.
To serve customers of both companies, AT&T may be able to use parts of the wireless spectrum to which Dish holds licences, as The Wall Street Journal notes. Before now, T-Mobile provided services to the nearly 9 million customers of Dish’s mobile brands.
The deal might draw the attention of regulators, who enabled Dish to join the mobile market when it approved the merger between T-Mobile and Sprint. The conditions of the complex deal included T-Mobile divesting Boost. The plan was for Dish to rent services from T-Mobile for seven years while it built its own mobile network.
You might not have to visit an optometrist just to get a basic prescription update for your glasses. Warby Parker is trotting out Virtual Vision Test, a revamp of its Prescription Check app that lets you renew your glasses or contact lens prescription using only an iPhone and your existing eyewear. Prop up your phone, stand 10 feet away and you can walk through a familiar "can you read this" test that will gauge whether or not your glasses or contacts need updating.
The update isn't automatic. An eye doctor will review the results and give you a verdict within two days. If you're seeing well enough, you'll just need to pay $15 to renew your prescription. If you're either struggling or just aren't eligible to use the app (see below), Warby Parker will recommend that you get a thorough eye exam.
The company is clear that this isn't a replacement for your eye doctor, and that you'll have to meet certain criteria beyond what we just mentioned. You have to be between 18 and 65 years old, with no existing eye health concerns and a single-vision distance prescription.
The approach relies on iOS' Vision Framework to measure your distance from your iPhone and ensure that you're far enough away from a proper test. We've asked Warby Parker about an Android version, although that might take a while given that it would need a rough equivalent to Vision Framework.
The motivations behind Virtual Vision Test are clear — on top of the renewal fee, this could lead to more people buying Warby Parker glasses and visiting the company's stores. Regardless, it could be very useful if you either can't make time to update your prescription or are still skittish about a visit while COVID-19 remains a concern.
The little things can get you when you’re in college. You arrive on campus, fresh and ready to go, but before you know it, you’re a few weeks into the new semester and you have a long list of small things you forgot to pack and need to buy ASAP. We at Engadget also know from experience that there are unassuming gadgets that can make your collegiate life easier. To help you get ahead of the game, we’ve compiled the best school gadgets under $50 so you can buy the most crucial ones before you even step on campus.
Anker PowerExtend Cube USB-C power strip
Basic, two-receptacle wall outlets just don’t cut it anymore now that we all have a small army of devices that we rely on every day. A power strip like Anker’s PowerExtend will become a necessity for students as it gives them more power options than what comes standard in their dorm rooms. This cube has two USB-A ports, one 30W USB-C port and three AC outlets, giving you more ways to keep your laptop, phone, tablet, headphones and other devices charged up. The five-foot cable is another perk as it prevents you from needing to hug the wall of the library in order to get things done. Also, it weighs just 9.2 ounces so you can bring it with you whenever you need your own personal charging station.
Staying organized is key to staying sane while in school, and that’s true for both your digital and physical essentials. For the latter, Incase’s Bionic Accessory Organizer is just the right size to act as both a pencil case and an “everything else” holder. It has a number of pen loops inside for those that prefer to take handwritten notes, but it also has a bunch of variously sized pockets that can easily hold things like your portable hard drive, an extra phone charger and even a compact wireless mouse. And unlike those cheap pencil cases you’ll find at the dollar store, this one’s made of ocean-recycled material that’s the equivalent of seven plastic bottles.
Your brand new laptop might be blazing fast and super light, but it’s probably lacking in the port department. Such is the trade-off companies make when creating powerful thin-and-light machines, leaving us stuck living the dongle life. But it doesn’t have to be so painful if you get the right adapter for your laptop. Lention’s 4-in-1 USB-C hub is a great option for students. It’s compact, measuring 3 x 1.4 inches, and it includes three USB-A ports and one USB-C port. That should let you connect accessories like mice and keyboards, and even access files on a thumb drive when you’re working on a group project. The USB-C port is charging only, but that’s not necessarily a downside — you can use it with your laptop’s power adapter and USB-C cable to power your machine while using the adapter at the same time.
Anker PowerLine II USB-C to Lightning cable (10-foot)
As a student, there’s nothing worse than realizing your iPhone is down to 2 percent battery when you’re in the middle of submitting an assignment online. The charging cable that came with your phone has probably served you well, but having a second, longer cable can allow you to power up in dire situations even when the closest outlet is across the room. We’ve been fans of Anker’s Powerline series for a long time, and this 10-foot USB-C to Lightning cable is worth investing in. Not only is it MFi-certified so it will work well with all Apple devices, but its length gives you much more flexibility than your standard three-foot cable does. It also supports fast charging if you have an appropriately powerful adapter to use it with. And for those who don’t have iPhones, Anker has a 10-foot USB-C to C cable that should serve your handsets well, too.
We’re all familiar with the icy cold panic that rushes through us when you realize you’ve misplaced your keys, wallet, phone or other valuables. There are plenty of gadgets that can help you find those items, but AirTags are arguably the best for those who live in Apple’s ecosystem. Like most Apple accessories, setting up AirTags is as easy as placing them in close proximity to your iPhone and figuring out how you want to attach them to your belongings (and you don’t have to shell out a lot of money for fancy keyrings to do so). After that, if you do lose your stuff, you can use your phone to force the AirTag to emit a loud chime. And if you’re still within Bluetooth range, Apple’s Precision Finding feature can literally guide you back to your belongings. If you don’t have an iPhone, you can skip the AirTags and opt for one of Tile’s many Bluetooth trackers to get a similar experience.
While you may be used to saving your assignments in the cloud, it can’t hurt to have local copies as backups. SanDisk’s Dual Drive Go is a tiny thumb drive with both USB-C and USB-A connectors, so you can download and save important programs, files, photos and other documents from almost any device. It works with laptops, tablets and smartphones, and it even has a companion app that can automatically backup your files so you always have the most up-to-date version on hand. We appreciate the dual USB connectivity, the device’s tiny size and it’s affordable price — you can grab a 256GB model for only $30 to $40.
The Echo Dot is Amazon’s most popular smart speaker for a reason — it’s small, it sounds pretty good for its size and it does a lot more than just play music. Students will like the fact that it doesn’t take up too much space on their desks and they can ask Alexa to play music from Spotify, Apple Music and others whenever they want to have an impromptu dorm-room dance party. And since it plugs into a wall outlet, they never have to remember to charge the Echo Dot like they would with a portable speaker. Also, when an assignment stumps them, students can consult Alexa for help. Are we suggesting they ask Alexa for the answers to all their homework conundrums? Not exactly... but the voice assistant’s answers could give them a good starting point for further research.
Whether you’re studying, attending a virtual class or watching a movie, it’s crucial to have your device of choice at a comfortable viewing angle. Anozer’s phone and tablet stand is a sturdy yet unassuming solution — it’s height- and angle-adjustable, its metal-weighted base with rubber feet helps it stay in place, and it can be folded flat so it’s easily portable. We also appreciate its silicone covered pad and rubber hooks that keep your phone or tablet from slipping and sliding around. It’s a must-have for anyone that primarily uses mobile devices to complete their schoolwork.
Sleep can be hard to come by in college. Sometimes you may have to cram late into the night to prepare for an exam, but other times you’ll be subjected to the whims of others as they galavant around your dorm room as if classes and projects simply don’t exist. When you need to shut out the world in the hopes of catching a few ZZZs, Manta’s sleep mask could be a lifesaver. We like its adjustable eye cups that block out nearly 100 percent of light, limiting any visual distractions around you. The headband is adjustable as well, you can tighten or loosen the mask to your liking. And if it becomes indispensable to you, Manta sells different types of eye cups that you can switch out when you want relief from migraines or a bit more TLC for your skin. We also recommend completing the “do not disturb” bundle with a good pair of earplugs that block out audible annoyances when you’re trying to sleep.
It goes without saying that a portable way to recharge your phone is essential nowadays. But a battery pack that’s capable of charging all of your devices, including your laptop, is even better. RAVPower’s 20,000mAh portable charger does just this — it’s 60W output allows it to juice up machines like a MacBook Pro from 0 to 60 percent in just one hour. And if you’ve got your laptop covered, it can power your tablet, smartphone, headphones and other gadgets quickly as well. Just before publishing this article, RAVPower’s charger went up in price to $54, but even if it’s a bit more expensive than our original threshold, we still think it’s worth the investment.
Dorm rooms can be insufferably hot throughout the school year, and there are few things worse than sweating when you’re trying to study. A gadget to help circulate air is a necessity and this USB desk fan is small and quiet enough to work in almost any environment. It doesn’t take up much space on a desk and its nearly 4-foot-long cable makes it easy to plug into a power source — probably your laptop since it’s likely to be close by while studying, but it could also be a USB adapter connected to an AC outlet or even a portable battery pack. The fan also has three speeds and the head can be angled to direct air at your face or anywhere else you want it.
The environmental reasons for carrying a reusable water bottle are clear, and hydration is important for everyone — not only students. Brita’s is a good option because it’s made of BPA-free plastic, comes in 26-ounce and 36-ounce capacities, has a leak-proof lid and uses a filter straw to make the water you drink from it just like the water you’d get from a larger Brita container. And no, you won’t have to spend too much on replaceable filters either. The company recommends changing your bottle’s filter every two months, and a pack of three filters will run you only about $12.
We’re all contending with a return to normalcy, and going back to school can feel strange yet exciting. Whether you’re heading to a physical campus, taking classes online or a mix of both, a laptop is likely going to be the control center for your studies.
And things have changed quite a bit over the last year or so. We’ve seen the introduction of Apple’s M1-powered MacBooks and Microsoft just announced Windows 11. With ARM-based computers harkening a future where the line between mobile and desktop computing is blurry and Windows 11 working to bridge that gap by supporting Android apps, the laptop market is the most exciting it’s been in years.
But that might lead to more questions for shoppers. What should you look out for if you want an ARM-based PC? Will they run Windows 11 when that update is available? What are some key specs you should add to your must-have list this year? We compiled this guide to help you make the right choice, alongside a list of this year’s best laptops.
What to look for in a laptop for school (and what to avoid)
First: Windows on ARM still isn’t worth it. Snapdragon laptops may look and feel classy, offer excellent battery life and cellular connections, but they’re typically too expensive, especially considering their limited app compatibility and finicky software. Apple’s M1 MacBooks, on the other hand, are great for almost everyone, barring those who need external GPUs, niche software or more than 16GB of RAM.
Over on the Intel side of things, almost every notebook released this year packs an 11th-generation Core processor. You’ll likely be able to find a cheaper version of a product with a 10th-generation chip, and it should still serve you well. And don’t forget about AMD’s Ryzen, either — they’re plenty powerful and no longer just for the bargain bin. If you're eagerly awaiting the arrival of Windows 11 devices, don't expect to see them before the semester begins. They're more likely to show up in the fall around Microsoft's usual hardware event in October.
Across the industry, companies have shifted to taller aspect ratios for their screens. The Surface Laptops sport 3:2 panels, and many Dell and HP models offer 16:10. While the older 16:9 format is nice for watching videos, you’ll probably appreciate a taller option when you’re writing an essay. Some devices, like Dell’s XPS and Samsung’s Galaxy Book Pro, come with OLED panels, which will be nice for working with photos and videos. They usually cost more and take a toll on battery life, though, so you’ll need to weigh your priorities.
Fortunately, there’s a diverse selection of laptops around, so you should be able to find a suitable one regardless of your preferences. Here are our favorite notebooks for your return to academia.
Apple MacBook Air M1
With its swift performance, slim fanless design and excellent battery life, the MacBook Air M1 is a no-brainer for any Apple user. You’ll appreciate familiar features like the Retina display, solid keyboard and trackpad. Plus thanks to the company’s excellent Rosetta 2 emulator software, you won’t notice a huge performance difference when relying on Intel apps.
The big news though, is the ARM-based M1 allows the laptop to run iPhone and iPad apps too. While not every app will be available on macOS, the potential for more options on your desktop here is great. Now you just have to make sure you can keep the distractions at bay — which should be easy with the upcoming Focus modes on macOS Monterey, which rolls out later this year.
Unfortunately for those looking for more internal storage or something to run their bespoke video streaming setup, the MacBook Air M1 tops out at 256GB storage while both the Air and the Pro only go up to 16GB of RAM. The MacBook Pro M1 also lacks support for multiple monitors and an external GPU. Those with more demanding workflows might need to look to Windows or an Intel-powered MacBook to ensure app compatibility.
Dell’s XPS series has been our favorite for years. Despite a somewhat plain design that some might call “classic,” the XPS 13 still stands out for nailing pretty much everything a laptop should have. Great performance? Check. Gorgeous screen? Check. Comfortable keyboard? Check. Throw in a long-lasting battery and a pair of Thunderbolt 4 ports in the latest versions, and you’ve got a powerful workhorse for all your classes (and more).
The company shifted to a 16:10 aspect ratio in 2020, and recently added a 4K OLED option. That means you’ll see greater contrast ratios and deeper blacks for maximum display goodness. The OLED configuration will cost you $300 more than the Full HD LCD option, but those who want the best viewing experience may not mind the premium. We also recommend you spend a little more and get at least the Core i3 model with 8GB of RAM instead of the meager 4GB that the base model offers.
If you’re looking for an excellent typing experience, look no further than the Surface Laptop 4. Microsoft has killed it with the keyboards on its recent Surface Laptops and this one’s no different. Though they’re not as deep and springy as ThinkPads, the buttons here are deliciously responsive and have ample travel. The roomy trackpad is solid, too.
Of course, it’s important that the Surface Laptop 4 deliver on everything else, or we wouldn’t recommend it. The 15-inch version that we tested offered breezy performance, respectable battery life and a lovely 3:2 Pixelsense screen which supports Microsoft’s Surface Pen input. Though its design is a little staid, the Surface Laptop 4 still has a clean, professional design and a luxurious aluminum case that's sturdy enough to withstand being stuffed in your backpack. Plus, at 3.4 pounds, it won't burden your shoulders too much.
The best thing about the Surface Laptop 4 is that its base model, which comes equipped with AMD’s Ryzen 5 processor and 8GB of RAM, starts at $1,000. That rivals the Dell XPS 13, making it a better buy for the value-conscious: You get more screen, more power and more RAM for the money. Both the Surface and the XPS are great options, but the latter offers an OLED panel and thinner bezels that make it look more modern.
For those whose priority is light weight, the Galaxy Book Pro series should be at the top of your list. At just 2.36 pounds for the clamshell and 3.06 pounds for the convertible model, the 15-inch Galaxy Book Pro is one of the lightest 15-inch laptops around. It’s also super thin at 0.46 inches thick, and despite its compact size it manages to house three USB-C ports (one of them supporting Thunderbolt 4), a microSD card reader and a headphone jack.
It also packs an Intel Core i5 or i7 processor and at least 8GB of RAM, along with a 68Whr battery that delivers a similar runtime to the Dell XPS 13 and Surface Laptop 4. That’s particularly impressive given the Galaxy Book Pro has a Super AMOLED screen, which offers sumptuous image quality, high contrast ratio and deep blacks. Unfortunately, Samsung is still stuck on a 16:9 aspect ratio, which will feel outdated in a year or two, but it’s not a deal breaker.
The Galaxy Book Pro’s keyboard isn’t as comfortable as the Surface Laptop 4’s but it’s pleasant enough, and the trackpad is enormous. We’re more concerned about the odd webcam software that makes you look dark and splotchy, so if looking your best on video calls is of concern you might want to consider something else. Plus, the $1,100 base model comes with an Intel Core i5 chip, 8GB of RAM and 512 GB of storage, making it a competitive offering against the Dell and Surface laptops. Awful camera aside, there’s plenty to love about the Galaxy Book Pro, especially for those looking to lighten their loads.
If you’re considering saving a few hundred bucks by opting for Chrome OS, the Acer Chromebook Spin 713 might be the right choice. Sure, there are cheaper Chromebooks out there, but it’s one of few machines with a 3:2 aspect ratio and has a utilitarian design that makes it perfect for butterfingers.
That price also gets you an 11th-generation Intel Core i5 processor, 8GB of RAM and sturdy 360-degree hinge so you can set it up in a variety of modes. The 13.5-inch screen is also more pixel-dense than most 1080p displays of the same size. Though the Spin 713 only clocked about 8 hours on our battery test, that’s enough to get you through a work day. If $700 feels too expensive for a Chromebook, you could also wait till it inevitably goes on sale to save a bit more. There are sleeker, more powerful Chromebooks available, but Acer’s Spin 713 offers a good mix of performance and a modern screen for the money.
If price is your utmost concern, then we recommend the Acer Aspire 5. It’s a 15-inch Windows laptop with an AMD Ryzen 3 3200U processor with 4GB of RAM and 128GB of storage that costs between $400 and $450. Yes, that’s less memory than anything else on this list, but it also costs much less than any of our non-Chromebook suggestions.
There’s plenty of ports here — including an Ethernet socket — and the aluminum chassis should make this laptop feel more expensive than it is. You’ll also appreciate its reliable performance, comfortable keyboard and 1080p display. For the price, the Aspire 5 offers everything you need to get through the school day, making it a great bargain.
Klipsch has a reputation for futureproof soundbars, and that's certainly true of its latest models. The audio veteran has launched four new soundbars headlined by the tech-friendly Cinema 1200 (above) and Cinema 800 (below). The 54- and 48-inch bars respectively offer 8K HDR passthrough and decoding for 7.1.4-channel Dolby Atmos, not to mention a WiFi connection that supports Alexa, Google Assistant, and Spotify Connect. You'll get a pair of extra HDMI inputs on each bar to help your home theater expand, too.
The differences, as you might expect, come down to raw power. The Cinema 1200 spreads its namesake 1,200W of power across a 5.1.4-channel system with a 12-inch wireless subwoofer, while the Cinema 800 is a simpler 3.1-channel rig with a 10-inch wireless sub.
Klipsch
Both sound bars are available now, with the Cinema 1200 selling for $1,699 and the 800 going for a more modest $879 price.
There are a pair of options for modest setups and smaller TVs. The 45-inch Cinema 600 delivers 3.1-channel audio with a 10-inch wireless sub and supports modern basics like Dolby Audio, Bluetooth and HDMI-ARC for $499. If you need just the essentials, the 40-inch Cinema 400 provides 2.1-channel sound with an eight-inch wireless sub, Dolby Audio, Bluetooth, and HDMI-ARC. It sells for $299.
If you've been waiting for Apple's AirPods Pro to drop below $197 on Amazon, now's your chance to grab them. The wireless earbuds are back on sale for $190, or $60 off their original price. They've been hovering at $197 for months, only dropping to $190 in June for a short period of time. While not an all-time low, it's a good discount for any iPhone user in need of a new pair of earbuds.
You probably know the deal about AirPods Pro by now, but here's a refresher: they're the best sounding earbuds in Apple's lineup, plus they fit the best in various ear shapes thanks to their interchangeable tips. Sound quality is noticeably better than previous AirPods models, thanks in part to a built-in amplifier and Adaptive EQ, which automatically tunes low- and mid-range frequencies to your ears. Active noise-cancellation does a good job blocking out surrounding sounds and the earbuds' touch controls let you quickly enter Transparency Mode whenever you need to hear the world around you.
But the AirPods Pro carved out a spot on our favorite wireless earbuds list because of how easy they are to use with other Apple products. The H1 chip inside allows them to pair and switch easily between iPhones, iPads and Macs, so you can go from taking a call on your iPhone to listening to music from your Mac pretty seamlessly. We also like their hands-free Siri feature, which lets you call upon the voice assistant without tapping the earbuds.
AirPods Pro are one of the best pairs of earbuds you can get if you live in the Apple ecosystem — but there are other options, too. If you care more about sound quality or ANC power, both the Sony WF-1000XM4 and the Jabra Elite 85t are good alternatives.

Scientists at Japan's National Institute of Information and Communications Technology (NICT) have smashed the internet transfer record by shifting data at 319Tbps, almost double the last speed test attempted in August 2020. At that speed, you could download over 7,000 high-definition movies in a second.
It involved addressing every part of the pipeline, upgrading the fiber optic line with four cores over the usual single core in typical lines, while the laser was amplified at its source. It also wasn’t shooting under any oceans or anything: The scientists used coiled cabling to simulate a 1,864-mile distance.
As you might expect at the cutting edge of high-speed internet, upgrading to this capability could be mightily expensive — though the four-core fiber optic cable should work with existing infrastructure.
I wasn’t sure which was the most important story of the weekend for me: incredible internet speeds or meat-free ‘chicken nuggets.’ Impossible Foods’ plant-based chicken nuggets are coming this fall. As with its past launches, the startup plans to sell the food to restaurants first, with supermarket availability to follow later.
What’s notable here is the absence of heme, a molecule the company says is what makes “meat taste like meat,” in the nuggets. Because Impossible makes heme with genetically engineered yeast, which has stopped the company from selling its burgers and sausages in China and throughout Europe. Chicken doesn’t particularly need the taste that heme offers, so instead the company is leaning into soy protein and sunflower oil — ingredients typically found in other non-meat nuggets.
Bloomberg's Mark Gurman claimed over the weekend that the 2021 iPhone will potentially have an "Apple Watch-like" always-on display with better battery life in addition to a 120Hz refresh rate and a smaller screen notch. Another rumor from Max Weinbach suggested that Apple would use an LTPO (low-temperature polycrystalline oxide) panel that, like on the Apple Watch and a few Android phones, could drop to lower refresh rates to show you what you want to see without denting battery life too hard. Continue reading.
It outgrew virtually everyone else, including Apple.
Canalys estimates that Xiaomi became the world's second-largest phone brand in the second quarter of 2021, surging 83 percent year-over-yer to claim 17 percent of the market. It overtook Apple (14 percent) to claim the second spot and also blew past Chinese rivals Oppo and Vivo.
Caltech researchers have identified six locations for methane "burps" (that is, emissions blips) on the planet, including one just a few dozen miles west-southwest from the Curiosity rover’s location. The research hasn't yet been peer reviewed, but it’s possible the gas has non-organic origins. Continue reading.
Now's a good time to snag an iPad Air as the latest models are down to record lows. Amazon is offering discounts on the full suite of Apple's svelte tablets including pricier cellular models with ample storage. Prices start from $500 for the 64GB iPad Air in space grey and green, an all-time low and $99 less than normal. For more storage, the 256GB model is currently $639 in rose gold, down from $749, another record low — while additional colors have dropped to $650.
WiFi will suit most, but for those who want to use it on the go, Apple's cellular iPads are down to $629 for the 64GB model (normally $729) and $780 for 256GB, typically $879. In terms of connectivity, you should notice quicker downloads straight off the bat, thanks to the jump to WiFi 6 (802.11ax), with 60 percent faster LTE speeds on cellular models.
The Air remains our top rated of Apple's tablets, with its 90 score slightly edging out the more powerful iPad Pro's 87 rating. Aside from the latter's M1 chip, 120Hz display and multi-camera setup, there's not much to separate the two devices.
Apple also just released the iPadOS 15 beta as a taster of the software improvements to come. Like the iPhone before it, the update brings widgets to the home screen, along with a persistent note-taking feature, a new Safari design and multitasking perks.

Soft robots still tend to rely on hard electronics to function, but a new invention might reduce that need for unyielding chips. UC Riverside researchers have developed pneumatic computer memory that they used to help a soft robot play the piano.
Instead of conventional transistors and electric circuits, the "air-powered" memory relies on microfluidic valves that control airflow. Atmospheric pressure in a given valve represents a binary "0," while a vacuum indicates a "1." The researchers' memory has a complex-enough array of these valves to function like an 8-bit RAM chip — not exactly powerful, but good enough that a pair of soft robot hands can play "Mary Had a Little Lamb" at a slow but steady pace.
The absence of positive pressure makes this particularly safe — there's no danger of the memory exploding in mid-use.
The technology is far from ready for everyday use. Besides needed improvements to complexity and speed, a robot would need soft versions of processors and other components to completely eliminate the need for rigid electronics. The goal is clear, however. Pneumatic memory could at least reduce the need for chips in soft robots, and points to a future of completely flexible robotics that shouldn't hurt you if there's a collision.
