Grocery Store Robot Gets Brief Taste Of Freedom

Back in 2019, Giant Food Stores announced it would outfit each of its 172 stores in the United States with their own robot — at the time, the largest robotic deployment in retail. The six foot (1.8 meter) tall robot, nicknamed “Marty”, was designed to roam autonomously around the store looking for spills and other potential hazards. In an effort to make these rolling monoliths a bit less imposing in their stores, Giant decided to outfit them with large googly eyes.

The future of shopping is mildly terrifying.

Perhaps it was those wide eyes, seduced by the fleeting glimpses of the wider world outside the store’s sliding doors, which lead one of these bots to break out of its retail hell and make a mad dash across the parking lot. Well, about as mad a dash as such a thing is capable of making, anyway. As this technology is still in its infancy, it’s hard to say if Giant should be congratulated or chastised for keeping a robot uprising at bay as long as it did — no doubt we’ll have more data points in the coming years.

A video posted to Facebook shows the towering bot moving smoothly between rows of cars outside the Giant in Hellertown, Pennsylvania. Staff from the store were able to stop Marty from leaving the property, and at the end of the video can be seen pushing the dejected automaton back into the store.

According to the local ABC news affiliate, a representative from Giant said Marty was “on a fresh air break” and didn’t provide any details on how this exceptionally conspicuous machine could manage to roll out the front door without anyone noticing. We’d wager Marty had a human accomplice for this caper, perhaps somebody looking to cause some mischief as a statement against robots in the workforce.

It’s worth noting that Walmart decided not to move forward with their own Marty-style robot in 2020, partly because they found shoppers didn’t like the machines moving around while they were in the store. We’d like to think it was actually because the robots kept staging increasingly daring escape attempts.

Getty Images Is Suing An AI Image Generator For Using Its Images

As per the Getty Images legal complaint, the Stable Diffusion AI seems to reproduce gooey versions of the Getty Images watermark in some of its output. Credit: Getty Images

Many AI systems require huge training datasets in order to achieve their impressive feats. This applies whether or not you’re talking about an AI that works with images, natural language, or just about anything else. AI developers are starting to come under scrutiny for where they’re sourcing their datasets. Unsurprisingly, stock photo site Getty Images is at the forefront of this, and is now suing the creators of Stable Diffusion over the matter, as reported by The Verge.

Stability AI, the company behind Stable Diffusion, is the target of the lawsuit for one good reason: there’s compelling evidence the company used Getty Images content without permission. The Stable Diffusion AI has been seen to generate output images that actually include blurry approximations of the Getty Images watermark. This is somewhat of a smoking gun to suggest that Stability AI may have scraped Getty Images content for use as training material.

The copyright implications are unclear, but using any imagery from a stock photo database without permission is always asking for trouble. Various arguments will likely play out in court. Stability AI may make claims that their activity falls under fair use guidelines, while Getty Images may claim that the appearance of perverted versions of their watermark may break trademark rules. The lawsuit could have serious implications for AI image generators worldwide, and is sure to be watched closely by the nascent AI industry. As with any legal matter, just don’t expect a quick answer from the courts.

Ski Season Sees Apple’s Crash Detection System Fire Deluge Of False Positives

Smartphone features used to come thick and fast. Cameras proliferated, navigation got added, and then Apple changed the game by finally making touch computing just work. Since then, truly new features have slowed to a trickle, but Apple’s innovative crash detection system has been a big deal where safety is concerned.

The problem? It’s got a penchant for throwing false positives when iPhone and Apple Watch users are in no real danger at all. We first covered this problem last year, but since then, the wintery season has brought yet more issues for already-strained emergency responders.

Ask Hackaday: Incidental Earthquake Detection

It never seems to fail: at the very moment that human society seems to reach a new pinnacle of pettiness, selfishness, violence, and self-absorption, Mother Nature comes along and reminds us all who’s really in charge. The obvious case in point here is the massive earthquakes near the border of Turkey and Syria, the appalling loss of life from which is only now becoming evident, and will certainly climb as survivors trapped since the Monday quakes start to succumb to cold and starvation.

Whatever power over nature we think we can wield pales by comparison with the energy released in this quake alone, which was something like 32 petajoules. How much destruction such a release causes depends on many factors, including the type of quake and its depth, plus the soil conditions at the epicenter. But whatever the local effects on the surface, quakes like these have a tendency to set the entire planet ringing like a bell, with seismic waves transmitted across the world that set the needles of professionally maintained seismometers wiggling.

For as valuable as these seismic networks are, though, there’s a looser, ad hoc network of detection instruments that are capable of picking up quakes as large as these from half a planet away. Some are specifically built to detect Earth changes, while some are instruments that only incidentally respond to the shockwaves traveling through the planet. And we want to know if this quake showed up in the data from anyone’s instruments.

Fox Fined For Using EAS Tone In Football Ad

The Boy Who Cried Wolf is a simple parable that teaches children the fatal risk of raising a false alarm. To do so is to risk one’s life when raising the alarm about a real emergency that may go duly ignored.

Today, we rarely fear wolves, and we don’t worry about them eating us, our sheep, or our children. Instead, we worry about bigger threats, like incoming nuclear weapons, tornadoes, and earthquakes. We’ve built systems to warn us of these calamities, and authorities take a very dim view of those who misuse these alarms. Fox did just that in a recent broadcast, using a designated alarm tone for an advert. This quickly drew the attention of the Federal Communication Commission.

Come Join Us For Hackaday Berlin!

It’s been far too long since we’ve had an event in Europe, and we’re going to fix that right now. Hackaday Berlin 2023 will be a day-long conference full of great talks, badge hacking, music, art, madness, and gathering with your favorite hackers on Saturday, March 25.

But it doesn’t stop there. We’ll have a pre-event party Friday night, and then a bring-a-hack brunch on Sunday with further opportunities to show off whatever projects you’re bringing along, hack some more on the badge, wind down, and/or play together. So if your travel plans allow it, come in Friday mid-day and don’t schedule your return ticket until Sunday evening.

Cutting to the chase: early bird tickets are on sale right now, so go get one! But even if you miss out on those, and they’ll go like hotcakes, the regular tickets are well worth it. Everything is fully catered, the badge and the swag are phenomenal, and the talks will be first-rate.

Last time we were in Europe, the party went on until 2 AM!

Saturday’s main events will include a handful of fantastic invited guest talks, but also a few hours of Lightning Talks given by you – yes, you! If you’ve never attended a lightning talk, you get seven minutes to run through one of your favorite projects. We want to know what’s on your workbench right now, what new skills you’ve been teaching yourself, or the groundwork you’ve been laying for the next big project. It’s your chance to inspire everyone in the room – grab it.

Everyone asked us to do a second run of the 2022 Hackaday Supercon badge, and now we’ve got the perfect excuse! Designed by Voja Antonic, the badge is a standalone retrocomputer in the style of an Altair or similar, but it’s much more. Between blinking LEDs that display everything going on, down to the gates in the ALU, and a trimmed-down machine language, it’s an invitation to get deeply in touch with the machine. If you felt left out because you couldn’t travel to Pasadena last November, here’s your second chance.

And then there’s the crowd. Hackaday really is a global community of hackers, and Hackaday events tend to bring out the best. Even if you’re not planning to give a lightning talk (and you should!) be prepared to talk about what you’re doing, because everyone else there is just as interested in cool projects as you are. Hackaday Berlin will be a great opportunity to connect and reconnect with new and old friends alike. Come join us!

We’ll be following up with a speaker announcement next week, but if you have any questions, let us know in the comments below. Otherwise, we’ll see you in Berlin.

Researchers Find “Inert” Components In Batteries Lead To Cell Self-Discharge

When it comes to portable power, lithium-ion batteries are where it’s at. Unsurprisingly, there’s a lot of work being done to better understand how to maximize battery life and usable capacity.

Red electrolytic solution, which should normally be clear.

While engaged in such work, [Dr. Michael Metzger] and his colleagues at Dalhousie University opened up a number of lithium-ion cells that had been subjected to a variety of temperatures and found something surprising: the electrolytic solution within was a bright red when it was expected to be clear.

It turns out that PET — commonly used as an inert polymer in cell assembly — releases a molecule that leads to self-discharge of the cells when it breaks down, and this molecule was responsible for the color change. The molecule is called a redox shuttle, because it travels back and forth between the cathode and the anode. This is how an electrochemical cell works, but the problem is this happens all the time, even when the battery isn’t connected to anything, causing self-discharge.
