Voyant Photonics raises $4.3M to fit lidar 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...

Sony’s new A7R IV camera is a 61 MP full-frame mirrorless beast

The camera’s image resolution is a “world first” for a 35mm equivalent full-frame digital sensor, Sony notes, and that’s not where the improvements on this successor to the wildly popular A7R III ends: The A7R IV also has 10fps rapid shooting with continuous autofocus and autoexposure tracking capabilities; 567 phase-detect autofocus points that cover 74% of the frame; real-time eye autofocus tracking for stills and movies, which can handle both human and animal subjects; 4K HDR movie recording without any pixel binning and with S-Log 2/3 support for editing (although without a 60p mode, as it caps out at 30p); ISO range of 100-32000 (and 50-102400 expandable); battery life of around 539 shots with the EVF or 670 shots without, and much more...

Petcube’s Bites 2 and Play 2 amuse pets and humans alike with Alexa built-in

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...

Archinaut snags $73 million in NASA funding to 3D-print giant spacecraft parts in orbit

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...

These robo-ants can work together in swarms to navigate tricky terrain

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...

Amazon reportedly ramps development on Alexa-powered home robot on wheels

The plan for Vesta was apparently to release it this year, but it’s not yet quite ready for mass production, according to Bloomberg’s sources. And while it could end up mothballed and never see the light of day, as with any project being developed ahead of launch, the company is said to be putting more engineering and development resources into the team working on its release...

Nintendo Switch Lite’s trade-off of whimsy for practicality is a good one

The changes mostly seem in service of bringing the price down, as it will retail for $199 when it goes on sale in September. That’s $100 less than the original Switch, which is a big price cut and could open up the market for Nintendo to a whole new group of players. But it’s also a change that seems to take away a lot of what made the Switch special, including the ability to plug it into a TV for a big-screen experience, or quickly detach the Joy-Con controllers for motion-control gaming with rumble feedback...

Apple stops selling the 12-inch MacBook, a computer you either loved or were confused by

The biggest indicator that Apple felt the MacBook was a showcase and crucial product was the name – it was just THE MacBook, without any addition epithets or qualifiers like “Air” or “Pro” (both of which predated its existence. And when it debuted, it brought a number of firsts for Apple’s laptop lineup, including USB-C for both data and power, a keyboard with butterfly mechanisms, a Force Touch trackpad and a new way of “terracing” batteries that allowed Apple to maximize the power available to the diminutive notebook without making any compromises on size...

Mario creator Miyamoto counters cloud gaming hype (but don’t count Nintendo out)

Speaking to shareholders at Nintendo’s annual general meeting, Miyamoto and other executives addressed a variety of issues, among them what some interpret as a failure to keep up with the state of the industry. Sony and Microsoft (together, amazingly) are about to lock horns with Google, Nvidia, and others in the arena of game streaming, but Nintendo has announced no plans whatsoever regarding the powerful new technology...

Watch a plane land itself truly autonomously for the first time

Now it would be natural to think that with the sophisticated autopilot systems that we have today, a plane could land itself quite easily. And that’s kind of true — but the autoland systems on full-size aircraft aren’t really autonomous. They rely on a set of radio signals emitted by stations only found at major airports: the Instrument Landing System, or ILS...
