Lidar is a critical method by which robots and autonomous vehicles sense the world around them, but the lasers and sensors generally take up a considerable amount of space. Not so with Voyant Photonics, which has created a lidar system that you really could conceivably balance on the head of a pin.
Before getting into the science, it’s worth noting why this is important. Lidar is most often used as a way for a car to sense things at a medium distance — far away, radar can outperform it, and up close, ultrasonics and other methods are more compact. But from a few feet to a couple hundred feed out, lidar is very useful.
Unfortunately, even the most compact lidar solutions today are still, roughly, the size of a hand, and the ones ready for use in production vehicles are still larger. A very small lidar unit that could be hidden on every corner of a car, or even inside the cabin, could provide rich positional data about everything in and around the car with little power and no need to disrupt the existing lines and design. (And that’s not getting into the many, many other industries that could use this.)
Lidar began with the idea of, essentially, a single laser being swept across a scene multiple times per second, its reflection carefully measured to track the distances of objects. But mechanically steered lasers are bulky, slow and prone to failure, so newer companies are attempting other techniques, like illuminating the whole scene at once (flash lidar) or steering the beam with complex electronic surfaces (metamaterials) instead.
One discipline that seems primed to join in the fun is silicon photonics, which is essentially the manipulation of …Read More
Petcube’s original Bites smart treat dispenser and Play pet camera with a built-in laser pointer were great for pet parents who couldn’t always be around to hang out with their furry charges, but the new Bites 2 and Play 2 come with one big new upgrade that make them far more versatile than the original: They both double as Alexa-powered smart speaker devices.
Both the Bites 2 and Play 2 can hear and respond to Alexa requests, with a four-microphone array that in my limited testing actually outperforms the Alexa mics built into my Sonos One and Sonos Beam speakers, which is pretty impressive for devices whose main features are serving up treats and keeping an eye on your pets. That’s on top of the Bites 2 being able to remotely dispense treats for your pet, and the Play 2 providing playtime away from home with a built-in laser pointer you can direct from your phone.
The Bites 2 and Play 2 also feature other improvements, including new wider angle lenses that offer full 180-degree views of your home for more likelihood you’ll spot your pets wandering around, and better Wi-Fi connectivity support with additional 5GHz networking, plus night vision and full HD video. Currently, the field of view is limited to 160-degrees, with an update to follow that will unlock the full 180; for most users, the 160 FOV is going to show you an entire room and then some.
With the Bites 2, you can also initiate video calls and chat with your pet, though my dog Chelsea basically is just confused by this. It is handy if I need to ask my partner if there’s anything else I’m forgetting to pick up from the store, however. And the treat-flinging feature definitely does appeal to Chelsea, especially now …Read More
Hero Labs, a London-based startup that is developing “smart” technology to help prevent water leaks in U.K. properties, has raised £2.5 million in seed funding. The round is led by Earthworm Group, an environmental fund manager, with further support via a £300,000 EU innovation grant and a number of unnamed private investors.
The new capital will be used by Hero Labs to accelerate development of its first product: a smart device dubbed “Sonic” that uses ultrasonic technology to monitor water use within a property, including the early detection of water leaks.
Founded in 2018 by Krystian Zajac after he exited Neos, a smart home insurer that was acquired by Aviva, Hero Labs was born out of the realisation that a lot of smart home technology either wasn’t very smart or didn’t solve mass problems (Zajac had also previously ran a smart home company focusing on ultra high net-worth individuals that delivered bespoke designs for things like motorised swimming pool floors or home cinemas doubling up as panic rooms).
Coupled with this, the Hero Labs founder learned that water wastage was a very costly problem, both financially and environmentally, with water leaks being the number one culprit for property damage in the U.K. ahead of fires, gas explosions or break-ins combined. This sees water leaks cost the U.K. insurance industry £1 billion per year, apparently.
“My vision for the company is to solve real-life problems with truly smart technology,” Zajac tells me. “From working at Neos and alongside some of the world’s largest home insurers I understood the problems that impacted ordinary homeowners and their families on a day-to-day basis. Perhaps most surprisingly, I learnt that water leaks are far and way the biggest cause of damage to homes… I also wanted to do more for the environment in my …Read More
A project to 3D-print bulky components in space rather than bring them up there has collected a $73.7 million contract from NASA to demonstrate the technique in space. Archinaut, a mission now several years in development from Made In Space, could launch as soon as 2022.
The problem at hand is this: If you want a spacecraft to have solar arrays 60 feet long, you need to bring 60 feet of structure for those arrays to attach to — they can’t just flap around like ribbons. But where do you stash a 60-foot pole, or two 30-foot ones, or even 10 six-foot ones when you only have a few cubic feet of space to put them in? It gets real complicated real fast to take items with even a single large dimension into space.
Archinaut’s solution is simple. Why not just take the material for that long component into space and print it out on the spot? There’s no more compact way to keep the material than as a brick of solid matter.
Naturally this extends (so to speak) to more than simply rods and poles — sheets of large materials for things like light sails, complex interlocking structures on which other components could be mounted… there are plenty of things too big to take into space in one piece, but which could be made of smaller ones if necessary. Here’s one made for attaching instruments at a large fixed distance from a central craft:
Made in Space already has contracts in place with NASA, and has demonstrated 3D printing of parts aboard the International Space Station. It has also shown that it can print stuff in an artificial vacuum more or less equivalent to a space environment.
The demonstrator mission, Archinaut One, would launch aboard a Rocket Lab …Read More
While the agility of a Spot or Atlas robot is something to behold, there’s a special merit reserved for tiny, simple robots that work not as a versatile individual but as an adaptable group. These “tribots” are built on the model of ants, and like them can work together to overcome obstacles with teamwork.
Developed by EPFL and Osaka University, tribots are tiny, light and simple, moving more like inchworms than ants, but able to fling themselves up and forward if necessary. The bots themselves and the system they make up are modeled on trap-jaw ants, which alternate between crawling and jumping, and work (as do most other ants) in fluid roles like explorer, worker and leader. Each robot is not itself very intelligent, but they are controlled as a collective that deploys their abilities intelligently.
In this case a team of tribots might be expected to get from one end of a piece of complex terrain to another. An explorer could move ahead, sensing obstacles and relaying their locations and dimensions to the rest of the team. The leader can then assign worker units to head over to try to push the obstacles out of the way. If that doesn’t work, an explorer can try hopping over it — and if successful, it can relay its telemetry to the others so they can do the same thing.
It’s all done quite slowly at this point — you’ll notice that in the video, much of the action is happening at 16x speed. But rapidity isn’t the idea here; similar to Squishy Robotics’ creations, it’s more about adaptability and simplicity of deployment.
The little bots weigh only 10 grams each, and …Read More
Luminar is one of the major players in the new crop of lidar companies that have sprung up all over the world, and it’s moving fast to outpace its peers. Today the company announced a new $100 million funding round, bringing its total raised to more than $250 million — as well as a perception platform and a new, compact lidar unit aimed at inclusion in actual cars. Big day!
The new hardware, called Iris, looks to be about a third of the size of the test unit Luminar has been sticking on vehicles thus far. That one was about the size of a couple hardbacks stacked up, and Iris is more like a really thick sandwich.
Size is very important, of course, as few cars just have caverns of unused space hidden away in prime surfaces like the corners and windshield area. Other lidar makers have lowered the profiles of their hardware in various ways; Luminar seems to have compactified in a fairly straightforward fashion, getting everything into a package smaller in every dimension.
Photos of Iris put it in various positions: below the headlights on one car, attached to the rear-view mirror in another and high up atop the cabin on a semi truck. It’s small enough that it won’t have to displace other components too much, although of course competitors are aiming to make theirs even more easy to integrate. That won’t matter, Luminar founder and CEO Austin Russell told me recently, if they can’t get it out of the lab.
“The development stage is a huge undertaking — to actually move it towards real-world adoption and into true series production vehicles,” he said (…Read More
Here’s a thing that should have never been a thing: Bluetooth-connected hair straighteners.
Glamoriser, a U.K. firm that bills itself as the maker of the “world’s first Bluetooth hair straighteners,” allows users to link the device to an app, which lets the owner set certain heat and style settings. The app can also be used to remotely switch off the straighteners within Bluetooth range.
Big problem, though. These straighteners can be hacked.
Security researchers at Pen Test Partners bought a pair and tested them out. They found that it was easy to send malicious Bluetooth commands within range to remotely control an owner’s straighteners.
The researchers demonstrated that they could send one of several commands over Bluetooth, such as the upper and lower temperature limit of the device — 122°F and 455°F respectively — as well as the shut-down time. Because the straighteners have no authentication, an attacker can remotely alter and override the temperature of the straighteners and how long they stay on — up to a limit of 20 minutes.
“As there is no pairing or bonding established over [Bluetooth] when connecting a phone, anyone in range with the app can take control of the straighteners,” said Stuart Kennedy in his blog post, shared first with TechCrunch.
There is a caveat, said Kennedy. The straighteners only allow one concurrent connection. If the owner hasn’t connected their phone or they go out of range, only then can an attacker target the device.
Here at TechCrunch we’re all for setting things on fire “for journalism,” but in this case the numbers speak for themselves. If, per the researchers’ findings, the straighteners could be overridden to the maximum temperature of 455°F at the timeout of 20 minutes, that’s setting up a prime condition for a fire — or …Read More
The biggest difference between the Nintendo Switch and the Nintendo Switch Light is that you can’t connect the Switch Light to a TV. There’s no dock or port designed for TV connection.
That’s not the only compromise you’ll have to make, as the Joy-Con controllers aren’t detachable. You can’t put your Switch on a table and keep the controllers in your hands for instance.
Of course, you can buy Joy-Con controllers or the more traditional Nintendo Switch Pro controller separately. You’ll have to find a way to charge your Joy-Con controllers without the Switch — the Charging Grip could do the job for instance.
But other than that, you’ll be able to play the exact same games that you’ve been playing on the Switch. As long as games support handheld mode, they will work on the Switch Lite — nearly 100% of games work in handheld mode.
The Switch Lite is slightly smaller and slightly lighter than the Switch — 0.61 lbs versus 0.88 lbs (277 g versus 399 g). It features a 5.5-inch touchscreen instead of a 6.2-inch touchscreen.
If you were wondering what would come after the 3DS, it sounds like the Switch Lite is the perfect replacement for a cheap handheld console. And the good news is that you should get better battery life. Nintendo says you will be able to play for 3 to 7 hours. In their testings, they could play Zelda: Breath of the Wild for 4 hours.
Nintendo will release the Nintendo Switch Lite on September 20. The device will be available in multiple colors — yellow, gray …Read More
It’s nice when people can come together and work through their differences to make it easier to watch stuff. That’s exactly what happened today, when the long-standing detente between Google and Amazon over streaming video services came to an end, with YouTube arriving on Fire TV and Prime Video making its way to Chromecast and Android TV.
Amazon’s second-generation Fire TV Stick, their Fire TV Stick 4K, the Fire TV Cube, Fire TV Stick Basic Edition and Fire TV Edition smart TVs made by partner OEMs will all get support for the official YouTube app globally starting today, and Amazon intends to extend support to even more of its hardware in the future. YouTube TV and YouTube Kids will also come to Amazon Fire TV devices later this year.
On the Google side, both its own Chromecast devices, as well as partner TVs and hardware that support Chromecast built-in, or that run Android TV, will gain support broadly for Prime Video. Plus, any Chromecast Ultra owners will also get access to Prime Video’s 4,000-title library normally reserved for Prime members, at no additional cost, as part of the new tie-up between the two companies.
Prime has been available on some Android TV devices to date, but it’s expanding to a much broader selection of those smart TVs and streaming boxes from today.
This has been a long time coming — several years in fact, with the most recent spat between the two coming as a result of Amazon’s implementation of YouTube on the Echo Show. Then, in May, the companies announced they’d reached an agreement to put the feud behind them in the interest of consumers, which is what resulted in this cross-platform launch today.

The Raspberry Pi 4 is a great little beast, but Tyler Ward identified a flaw in the USB Type-C connector. The Raspberry Pi Foundation confirmed to TechRepublic that the design flaw is real, and that your Raspberry Pi 4 might not work with all USB-C cables.
It’s not really a dealbreaker, but you can expect a future board revision with a proper implementation of the USB-C protocol. But if you find yourself scratching your head and you don’t understand why your Raspberry Pi is not powering up, now you know why.
The Raspberry Pi Foundation has released the schematics of the board. And there’s a missing CC resistor that let sophisticated chargers negotiate current with the device.
Given that USB-C is a complicated connector, some cables are electronically marked, which means that they have an integrated chip to support a wide range of devices.
For instance, you can use a MacBook Pro charger with plenty of USB-C devices. The charger just figures out how much power it needs to deliver.
But the Raspberry Pi 4 doesn’t support electronically marked cables, such as Apple’s USB-C cables or Google’s Pixel 3 cables. The device is incorrectly identified as an audio adapter accessory.
Fortunately, it doesn’t damage the Raspberry Pi 4 and it doesn’t create any fire hazard. The device just doesn’t power up.
"I expect this will be fixed in a future board revision, but for now users will need to apply one of the suggested workarounds. It's surprising this didn't show up in our (quite extensive) field testing program,” Raspberry Pi Foundation founder Eben Upton told TechRepublic.
A simple workaround is to buy a non e-marked cable or charger. The Raspberry Pi Foundation is selling an $8 USB-C charger for instance. In my testing, it has been working fine for …Read More
