From robot insects to human-sniffing sensors, this rescue tech could save lives
Elon Musk’s futuristic “mini-sub” ultimately wasn’t used in the recent daring rescue of 13 people trapped in a cave in Thailand. However, its much-publicized existence reminded the world of the important role similarly cutting-edge technology will increasingly have a role to play in similar disaster rescue efforts.
From inflatable vine robots to skin-sniffing smart sensors, read on for six of the high-tech tools which could one day save your life.
Search and rescue drones
We’ll start with the most common technology on this list: drones. Forget being tools of the future; examples of camera-equipped unmanned aerial vehicles (UAVs) being employed by emergency response teams are already playing out.
Earlier this year, the technology was used to help guide emergency responders to the residence of a resident in Hawaii whose home risked being swallowed up by lava following a volcanic eruption. As drones’ flight time increases, these will only become a more widespread tool in the arsenal of lifesavers.
A growing vine robot
Created by researchers at Stanford University and the University of California, Santa Barbara, this flexible, vine-like robot is capable of growing up to 236 feet in length by pumping itself full of air.
By doing this, it can snake through complex environments, lifting objects, and extending through gaps just 10 percent of its diameter. Because of its hose-like design, the robot could be used for moving materials from rescuers to whoever needed to be rescued.
“One of the areas we’re most interested in is search and rescue,” Professor Elliot Hawkes, lead researcher on the project, told Digital Trends. “We imagine growing the robots through rubble and debris to help find trapped survivors. The robot could deliver water or oxygen to the survivor, and possibly pry rubble off the survivor.”
Harvard’s insect rescue-bots
If you’re in need of a savior in a disaster scenario, what could be a more welcome sight than a rescue robot that’s literally capable of walking on water? That’s what Harvard researchers have developed with its ongoing insect-inspired Harvard’s Ambulatory MicroRobot (HAMR) project.
These miniature rescue bots may be diminutive, but they show off some impressive capabilities, including scampering over ground at high speeds, walking on top of and under water, and — in the future — hopefully climbing and jumping, too.
“Think about a scenario in which a building collapsed due to earthquake or tsunami,” Kevin Chen, a postdoctoral fellow at Harvard University, told Digital Trends. “There are many people trapped in confined and cluttered environments. We can send in a swarm [of hundreds] of these small robots into the site to search for survivors. These robots should be able to overcome obstacles on land. In addition, when facing water puddles, the robots need to bypass these by walking on the water surface or dive down to avoid obstacles on the water surface.”
SmokeBot
Örebro University
No, it’s not a cigar-chomping automaton like Bender from Futurama. Instead, SmokeBot is a robot designed to assist firefighters when they enter smoke-filled buildings. The big selling point of SmokeBot is its ability to spot things firefighters may not — thanks to a combination of gas sensors, radar, a laser scanner, and a thermal camera.
It can then relay this information in the form of maps of its surroundings for assisting fire services or search-and-rescue teams. While the robot has to be remote-controlled by a human user, by way of WiFi, it possesses the smart ability to autonomously return to the last position it had good internet reception if this connection is cut off.
“[We were interested in using robots for] operating in low-visibility environments, a scenario where robots could be very helpful, but in which it was not possible to use them prior to SmokeBot,” Achim Lilienthal, project coordinator and professor of Computer Science at Sweden’s Örebro University, told Digital Trends.
Human-sniffing sensors
American Chemical Society
Finding survivors in the aftermath of disasters, such as earthquakes or bombings, is a major challenge — with serious time constraints. To help with this, researchers from Austria, Switzerland, and Cyprus have developed an inexpensive sensor designed to literally “sniff out” survivors who may be trapped.
The sensor is both light and portable enough that it could be carried by first responders or mounted onto a drone. It can detect a person’s chemical signature at even the tiniest, trace-level concentrations.
“We tested our sensors in a human entrapment simulation,” Sotiris Pratsinis, Professor of Process Engineering at ETH Zurich in Switzerland, told Digital Trends. “Volunteers were enclosed in a gas-tight chamber to accumulate their breath and skin emissions. The sensors rapidly detected human presence by sensing tiny amounts of these chemicals, at levels unprecedented for portable detectors — down to three parts per billion. The next step is to test the sensor array in the field with first responders under conditions similar to those expected in the aftermath of a calamity.”
MIT’s Cheetah bot
Certainly the coolest-looking robot on this list, Cheetah is a four-legged robot built by MIT engineers. Currently in its third iteration, the 90 lbs Cheetah can handle uneven terrain, make some impressive leaps, and even navigate effectively in pitch black darkness thanks to some smart spatial awareness tech.
The team behind the work hope that it can one day be used as part of rescue missions in disaster relief situations.

A Japanese startup is planning an artificial shooting star show by 2020
Barcroft Media/Getty Images
Who says you have to wait around for a meteor shower? Certainly not ALE Co., a Tokyo-based startup that wants you to wish upon a shooting star anytime you’d like. The company is looking to develop a system that would offer paying customers “shooting stars on demand,” and as per a report by Japan Times, the first man-made meteor shower in the history of the world could take place in just two years.
The system depends upon two satellites, both of which are currently being developed. The first should be launched into orbit in March 2019, while its sibling would take flight sometime next summer. Each satellite will carry around 400 tiny spheres, each of which contain a proprietary chemical formula that would mimic falling stars in the sky. Think of them, in some ways, as extraterrestrial fireworks. Each of the little spheres could be reused, which means that they could be repurposed for between 20 and 30 artificial shooting star shows.
The satellites purportedly have a lifespan of around 24 months, and would be programmed to send the tiny fireworks flying in the right place, speed, and direction in order to achieve visible illumination even over an extremely crowded metropolitan area (think Tokyo or New York City). And because they would be shot out in space, millions of viewers could be able to enjoy the show from their own homes, ALE claims.
“We are targeting the whole world, as our stockpile of shooting stars will be in space and can be delivered across the world,” ALE CEO Lena Okajami told reporters.
Should all systems continue to operate smoothly during these planning and production phases, both satellites could be in place by February 2020, and an initial test run could be ready to go later in the spring. That means we’ve less than two years to think of all of our most pressing desires and make as many wishes as possible.
The first test is slated to take place over Hiroshima, which was chosen thanks to its weather, landscape, and cultural background, the company said. It’s unclear exactly how much you’ll have to pay in order to order a meteor shower of your own. The initial tests have a budget of $20 million, which includes the cost of launching a pair of satellites.

The Pixel 2 XL’s still got it, which bodes well for the Pixel 3

If you can avoid paying full price, the Pixel 2 XL is still worth it.
We’re sometimes guilty of being a little fickle when it comes to older phones. As new toys arrive, and release cycles grind on, phones from years past are left to collect dust.
The Google Pixel 2 XL is an exception. It has unquestionably aged better than just about any Google phone before it, be it a Nexus or a Pixel. For a phone that had a tumultuous launch, thanks to some concerns around the display, the Pixel 2 XL stood the test of time better than I could’ve imagined.
We’re still a few months away from the next generation of Pixel phones, and with the final version of Android 9.0 dropping very soon, plus price drops on the Google store and elsewhere, this phone is still a tempting proposition. If you care about having the latest Android software and Google features, then the Pixel 2 will be running software in August that other flagships like the Note 9 probably won’t get until at least a couple months into 2019.
Of course, there’s more to a phone than the version of Android it runs. The Pixel 2 XL is a generation behind the current crop of high-end Androids if you just look at the spec sheets. You get last year’s Snapdragon 835 instead of this year’s 845. 4GB of RAM versus the increasingly standard six.
Real-world performance, though, is basically on par with many of the Snapdragon 845 phones we’ve been using over the past few months, with only tiny differences in app load speeds. Even then, it’s pretty much a coin toss as to which one feels faster to use. The only downside I’ve really seen has to do with that four gigabytes of RAM. Compare it to the OnePlus 6, for instance, with its monstrous eight gigs of RAM, and it’s clear OnePlus’s phone is the superior multitasker.
Having the latest version of Android is all well and good — the Pixel 2 XL will have Android 9 comfortably before any other phone. And it’s guaranteed for platform updates through until Android R in 2020. But the real strengths of the Pixel comes from the extra stuff Google’s layered on top. Features like “Now Playing”, which identifies music playing when you’re out and about, are things that still delight me whenever I switch back to the Pixel. And then there’s the legendary Pixel camera, which is so good mostly because of the HDR+ processing that Google’s developed over the past few years.
Sure, there are ports of the Pixel camera for other phones, but none work as well as the real deal on a Pixel 2.

This is still a top-three camera. Although it’s beaten in one or two areas by the Galaxy S9 and Huawei P20 Pro, the Pixel’s camera is absolutely a reason to recommend it over other flagships. It’s not quite the best anymore in low light, but it still captures a ton of color detail in the dark. And dynamic range is spectacularly good. Photos from the Pixel 2 have a magical quality that’s hard to replicate on any other handset. And it’s still the camera, more than anything, that lures me back to a Pixel now and again, even when reviewing newer and shinier things.
Something else that’s held up surprisingly well is this phone’s battery life. Even after around nine months of use, with hardware that’s a generation old, my Pixel 2 XL’s longevity compares favorably to the Galaxy S9+, OnePlus 6, LG G7, HTC U12+ and just about any other 2018 flagship you might care to mention. (The only exception being Huawei’s Mate 10 and P20 Pro, with their extra-large batteries.)
The Pixel 3 is just around the corner. Nevertheless, if you can find the Pixel 2 XL with a reasonable discount, it’s absolutely still worth picking up. The phone was briefly discounted on the Google Store, but most outlets have reverted back to the $849 base price, which you definitely shouldn’t pay. If you are buying outright, Amazon has a few refurb options at a more palatable price point.

Other odds and ends for a lazy Sunday:
- Am I the only one having deja vu around the new proactive Google Assistant? This new feature essentially recreates many of the capabilities of Google Now when it debuted back in 2012 with Android 4.1 Jelly Bean. We’ve come full circle.
- Hopefully this is the death knell for the current Google Feed, which as I mentioned here is currently little more than a below-average news aggregator. Surely the new proactive Assistant is poised to replace the Feed on the next round of Pixel phones. The new Google News app leaves little reason for the Feed to continue to exist in its current form.
- Looks like the Samsung Galaxy Watch (probably) won’t run Wear OS after all. Makes sense, for the reasons I laid out in this video. Samsung shipping a Wear OS watch could only happen if Google were to essentially buy Samsung’s cooperation. Even then, there’s the question of what would happen with other Tizen gadgets like the Gear Fit series, which are a poor fit for Wear OS’s UI. Either way, in the absence of Google bucks to sweeten the deal, Tizen is the far more likely bet.
- Google got slapped with a $5.1bn fine this week, and Russell Holly has a great explainer of the issues involved. The company has always walked something of a tightrope with “open” Android. AOSP Android is still open-source, but progressively less and less of what you or I might think of as Android on a phone is available without playing by Google’s rules. Realistically, you need to cooperate with Mountain View and work within the Google ecosystem to get anywhere with Android in Western markets — which is the crux of the EU’s argument around how Google has competed unfairly. Google will appeal, of course. But if it loses, significant structural changes could be coming to Android, particularly around Google Play Services, which ties app compatibility and device security into reliance on Google services.
- Fuchsia is exciting, and we got a tantalizing look at a potential timeframe for Google’s next-gen OS this week. Fuchsia is supposedly an OS for everything from smart speakers to laptops, and on phones it’ll allow Google to solve some of the big built-in problems with Android — fragmentation, security, slow platform updates — from the get-go. Developers will need a long lead time to prepare for Fuchsia, and even after it arrives, you can bet it’ll run “legacy” Android apps just fine. This should be an orderly transition if/when it happens.
- A lot has been made of Android as we know it potentially going away in five years. (Which, amusingly, would make Android U the last version, just before we start to get to the more problematic letters for “sweet treat” nicknames.) But let’s remember that Android is ultimately just a brand. When Fuchsia comes to phones, Google can call it whatever it wants. I’m also willing to bet Fuchsia won’t be a user-facing brand in the same way Android is today.
- We’re still waiting on that HTC U12+ OTA. So far only Taiwan has received the update to “fine-tune” the problematic digital buttons. It’s apparently due in the U.S. by the end of the month. I genuinely hope something can be salvaged from this phone, which aside from its crappy buttons is actually pretty good.
- (After a month with the aforementioned crappy buttons, though, does anyone besides me still care about the U12+? Surely, at this point, the damage is already done.)
- Another update that has actually arrived this week: The OxygenOS 5.1.9 OTA for the OnePlus 6, which brings a big, noticeable improvement to dynamic range, sharpness and low-light performance in the camera. I’ve been impressed with what I’ve seen so far, and will hopefully have more to share very soon.
- Quick protip for anyone thinking about leaking a photo of an unannounced phone: Blanking out the IMEI is a good start, but if you forget about those barcodes, holograms and other identifiers, you’re still likely getting fired:
Yeah we can probably just blank out the serial number. Don’t need to worry about those barcodes or holograms pic.twitter.com/D7Z8lcf0Iw
