This autonomous spray-painting drone is a 21st-century tagger’s dream – TechCrunch

Published

on


Whenever I see an overpass or billboard that’s been tagged, I worry about the tagger and the danger they exposed themselves to in order to get that cherry spot. Perhaps this spray paint-toting drone developed by ETH Zurich and Disney Research will take some of the danger out of the hobby. It also could be used for murals and stuff, I guess.

Although it seems an obvious application in retrospect, there just isn’t a lot of drone-based painting being done out there. Consider: A company could shorten or skip the whole scaffolding phase of painting a building or advertisement, leaving the bulk of painting to a drone. Why not?

There just isn’t a lot of research into it yet, and like so many domain-specific applications, the problem is deceptively complex. This paper only establishes the rudiments of a system, but the potential is clearly there.

The drone used by the researchers is a DJI Matrice 1002, customized to have a sensing rig mounted on one side and a spraying assembly on the other, counterbalancing each other. The sprayer, notably, is not just a nozzle but a pan-and-tilt mechanism that allows details to be painted that the drone can’t be relied on to make itself. To be clear, we’re still talking broad strokes here, but accurate to an inch rather than three or four.

It’s also been modified to use wired power and a constant supply of paint, which simplifies the physics and also reduces limits on the size of the surface to be painted. A drone lugging its own paint can wouldn’t be able to fly far, and its thrust would have to be constantly adjusted to account for the lost weight of sprayed paint. See? Complex.

The first step is to 3D scan the surface to be painted; this can be done manually or via drone. The mesh is then compared to the design to be painted and a system creates a proposed path for the drone.

Lastly the drone is set free to do its thing. It doesn’t go super fast in this prototype form, nor should it, since even the best drones can’t stop on a dime, and tend to swing about when they reduce speed or change direction. Slow and steady is the word, following a general path to put the nozzle in range of where it needs to shoot. All the while it is checking its location against the known 3D map of the surface so it doesn’t get off track.

In case you’re struggling to see the “bear,” it’s standing up with its paws on a tree. That took me a long time to see, so I thought I’d spare you the trouble.

Let’s be honest: This thing isn’t going to do anything much more complicated than some line work or a fill. But for a lot of jobs that’s exactly what’s needed — and it’s often the type of work that’s the least suited to skilled humans, who would rather be doing stuff only they can do. A drone could fill in all the easy parts on a building and then the workers can do the painstaking work around the windows or add embellishments and details.

For now this is strictly foundational work — no one is going to hire this drone to draw a Matterhorn on their house — but there’s a lot of potential here if the engineering and control methods can be set down with confidence.

Google isn’t moving Legacy G Suite users again, despite admin console warnings

Published

on

Google

Grandfathered-in “Legacy G Suite” users got a scare recently when another new “transition” message started popping up in the Google Admin console. “The transition to Google Workspace has started,” said the new message that suddenly appeared in people’s accounts. This was after Legacy G Suite users went through a contentious transition last year, where Google’s opening position involved shutting down their accounts if people didn’t start paying, but eventually, it was talked into not doing that. A Google spokesperson tells us the Workspace transition message was “a bug that surfaced an old banner from earlier in the process last year, and our team is working on removing it. More changes are not happening at this time, and those who previously opted-in for personal use are not expected to take any further action.”

We’ve received a few questions about this message, and this Reddit post has people wondering what the deal is, but it’s just a bug. That’s great because Legacy G Suite users have gone through enough already. To recap, Google currently offers businesses the option to pay a monthly fee for a Google/Gmail account that ends in a custom domain name instead of @gmail.com. Today this is called “Google Workspace,” but due to Google’s constant rebrands, it was first called “Google Apps for your Domain,” then “Google Apps,” and then “G Suite.” Google’s custom domain service was not always paywalled and not always exclusively aimed at businesses—it was free from 2006 to 2012. Google even pitched these accounts to families as a way to let everyone have similar email addresses. Some people did so, which means today they are getting a paid service for free.

Don't believe a word of this message.

Last year, the Google accounting department turned its Eye of Sauron on these long-term users and threatened to take away their nearly 16-year-old accounts if they didn’t start paying a business rate for these formerly free and not necessarily business accounts. After a public outcry, Google eventually left these “Legacy G Suite accounts” alone after making users confirm that they were using their accounts for “non-business” purposes. After that, everything was settled.

Legacy G Suite users are specifically not a part of “Workspace,” which is a paid service. So this new message that popped up yesterday suggests they would have moved to another new service. Even though Google says it’s an error that users could see this message, actually following the prompt would lead you to another error message about “Google Workspace for personal use” which is a product that does not exist. Workspace has tiers like “Business Starter,” and grandfathered-in users are on “Legacy G Suite”, but “Workspace for personal use” is not a thing. Apparently, this was all the beta branding for the original plan last year, and somehow it all got published yesterday.

Google Workspace for personal use would be a great product for Google to sell, by the way. We’ve complained before that while Apple and Microsoft both sell custom domain email services to consumers at a reasonable rate, Google does not, only offering business email at much more expensive rates. A big part of the Legacy G suite problem is that these personal users have nowhere to go inside Google.

Apple Q1 earnings miss the mark almost across the board

Published

Enlarge / Apple CEO Tim Cook.

Apple reported its earnings for Q1 2023 today, and it was one of the company’s poorest-performing quarters in recent years. It was the company’s biggest decline since 2016 and the first since 2019. Overall revenue was down more than 5 percent year-over-year as the company failed to match sales from the same quarter last year across most of its hardware categories.

iPhone revenue was $65.78 billion for the quarter, down 8.17 percent year over year. Similarly, “Other Products”—which includes the Watch, AirPods, and some other outliers—was down 8.3 percent year over year at $13.48 billion. The real underperformer was the Mac, which was down almost 30 percent at $7.74 billion.

The two parts of the business that did grow were services— which include things like Apple Music and TV+, iCloud, and AppleCare—and the iPad. Services were up 6.4 percent at $20.77 billion, while the iPad grew 29.66 percent to $9.4 billion.

CEO Tim Cook said in the company’s earnings call that Apple faces a “challenging macroeconomic environment.” Besides that, he named two other main factors behind the down quarter: production and supply issues in China and a strong US dollar. Apple struggled to meet consumer demand across many of its products, with shipping sometimes running several weeks behind. Cook said that while Apple might have met analysts’ estimates had the supply issues not been a factor, it’s impossible to know for sure.

On the bright side, Apple says it has resolved many of those supply problems for now and that there are now 2 billion active Apple devices in users’ hands worldwide. And obviously, $117.15 billion in revenue for the quarter is still huge, even if it didn’t meet expectations or match last year.

Apple declined to give guidance on what it expects for the next quarter. It has not done so for any quarter since the pandemic began in 2020.

Razer’s $280 mouse is covered in gaping holes 

Published

Razer

There are a lot of cookie-cutter mice out there that, although made by different manufacturers, have the same shapes and features but rely on mild changes in color or sensor specs to differentiate themselves. So when Razer announced the Viper Mini Signature Edition (SE) today, a wireless mouse that looks like it forgot to get dressed, we took notice.

The Viper Mini SE uses a magnesium alloy chassis “exoskeleton,” as Razer describes it. Lines of dark gray stretch across the mouse’s palm area, creating a web-like design and bold, gaping holes. Razer’s using an extreme take on the honeycomb design, which has holes drilled into a mouse’s chassis to reduce weight. However, the typical honeycomb mouse, like the Glorious Model I, has many more holes that are smaller, while the Viper Mini SE has holes that are so big, it looks like you could poke your finger through them.

At first look, I’m immediately concerned about the mouse’s durability. Despite what Razer claims, I still think I’m more likely to break a mouse with 18 holes in it than one with none. Large openings can also attract dust and debris, but bigger holes should make the mouse easier to clean with, for example, an air blower than a  honeycomb mouse topped with more, smaller openings.

Razer graciously gives the mouse a three-year warranty, which is one year longer than it usually gives mice. We’ll be keen to check out reviews and long-term experiences with the Viper Mini SE to see how it fares, especially among power users, like gamers, who tend to use their mice aggressively.

From a glass-half-full perspective, the cavernous mouse could have the benefit of helping the hand on top of it stay cool. With less contact between the user’s hand and the electronics, plus more air flow, users may find their hands clamming up less easily during long hours of intense use. Razer didn’t go so far as to install a cooling fan in the mouse like Marsback’s Zephyr, though.

Big holes help make the Viper Mini SE Razer’s lightest mouse. It’s 1.73 ounces, which is about 30 percent lighter than the Viper Mini (2.15 ounces) with the same form factor and nearly identical dimensions. It’s still not the lightest mouse around, however. For example, Cooler Master’s MM720 is also 0.11 pounds, and Finalmouse has sold mice weighing as little as 1.48 ounces.

With the weight savings gained, it would have been nice if Razer added buttons to the mouse’s right side so it could be truly ambidextrous, like the Razer Viper Ultimate.

Razer used magnesium alloy for the mouse because it had the preferred “strength-to-weight ratio.” Plastic, it said, was less sturdy with drilled holes and had minimal weight reduction comparatively. And titanium, while lightweight, stronger, and sturdier, had fabrication limitations. Finally, fabrication limits, plus a heavier weight than plastic, precluded Razer from making the Viper Mini SE with carbon fiber.

According to Razer’s press release, the mouse is made “with an injection-molded exoskeleton that is then CNC machined and polished. The exoskeleton shell then undergoes passivation to reduce any susceptibility to corrosion, after which it is painted and assembled. At each step, each unit is meticulously inspected…”

The Razer Viper Mini SE targets gamers seeking a mouse that’s as easy as possible to flick around their desk. But a featherweight mouse with a high dots-per-inch (DPI) spec (up to 30,000 DPI in the Viper Mini SE’s case) can also appeal to users of increasingly high-resolution monitors and multi-screen setups, or those who find their arm or hand getting tired while mousing.

If you’re looking for a lot of chassis for your buck, this isn’t it. The wireless peripheral will cost a whopping $280 when it debuts February 11.
