Pepper, SoftBank's robot, malfunctioned during scripture readings, took breaks in exercise class and couldn't recognize the faces of family members. From a report: Having a robot read scripture to mourners seemed like a cost-effective idea to the people at Nissei Eco, a plastics manufacturer with a sideline in the funeral business. The company hired child-sized robot Pepper, clothed it in the vestments of Buddhist clergy and programmed it to chant several sutras, or Buddhist scriptures, depending on the sect of the deceased. Alas, the robot, made by SoftBank Group, kept breaking down during practice runs. "What if it refused to operate in the middle of a ceremony?" said funeral-business manager Osamu Funaki. "It would be such a disaster." Pepper was fired. The company ended its lease of the robot and sent it back to the manufacturer. After a rash of similar mishaps across Japan, in which Pepper botched its job at a nursing home and gave baseball fans a creepy feeling, some people are saying the humanoid itself will need a funeral soon.

"Because it has the shape of a person, people expect the intelligence of a human," said Takayuki Furuta, head of the Future Robotics Technology Center at Chiba Institute of Technology, which wasn't involved in Pepper's development. "The level of the technology completely falls short of that. It's like the difference between a toy car and an actual car." The robotics unit of SoftBank, a Tokyo-based technology investor, said in late June that it halted production of Pepper last year and was planning to restructure its global robotics teams, including a French unit involved in Pepper's development. Still, the company says the machine shouldn't be sent to the product graveyard. Spokeswoman Ai Kitamura said Pepper is SoftBank's icon and still doing good work as a teacher and a temperature taker at hospitals. She declined to comment on any of its individual mishaps.

SoftBank introduced the humanoid to the world in 2014 and started selling it the next year. "Today might become a day that people 100, 200 or 300 years later would remember as a historic day," SoftBank Chief Executive Masayoshi Son said at the introduction. SoftBank sold the robots to individuals for about $2,000, plus monthly fees for subscription services, and rented them to businesses starting at $550 a month. Japan has had a love affair with humanlike robots going back to Astro Boy, a robot featured in a 1960s animated television series, but there have also been breakups. Honda Motor's Asimo once kicked a soccer ball to then-President Barack Obama. Toshiba's Aiko Chihira, an android with a woman's name and appearance, briefly worked as a department store receptionist. After a while, both disappeared. More recently, a Japanese hotel chain created a robot-operated hotel, with dinosaur-shaped robots handling front-desk duties, only to reverse course after the plan failed to save money and created more work for humans.

Robots have a hard time improvising, and encountering an unusual surface or obstacle usually means an abrupt stop or hard fall. But researchers have created a new model for robotic locomotion that adapts in real time to any terrain it encounters, changing its gait on the fly to keep trucking when it hits sand, rocks, stairs and other sudden changes. From a report: Although robotic movement can be versatile and exact, and robots can "learn" to climb steps, cross broken terrain and so on, these behaviors are more like individual trained skills that the robot switches between. Although robots like Spot famously can spring back from being pushed or kicked, the system is really just working to correct a physical anomaly while pursuing an unchanged policy of walking. There are some adaptive movement models, but some are very specific (for instance this one based on real insect movements) and others take long enough to work that the robot will certainly have fallen by the time they take effect.

The team, from Facebook AI, UC Berkeley and Carnegie Mellon University, call it Rapid Motor Adaptation. It came from the fact that humans and other animals are able to quickly, effectively and unconsciously change the way they walk to fit different circumstances. "Say you learn to walk and for the first time you go to the beach. Your foot sinks in, and to pull it out you have to apply more force. It feels weird, but in a few steps you'll be walking naturally just as you do on hard ground. What's the secret there?" asked senior researcher Jitendra Malik, who is affiliated with Facebook AI and UC Berkeley. Certainly if you've never encountered a beach before, but even later in life when you have, you aren't entering some special "sand mode" that lets you walk on soft surfaces. The way you change your movement happens automatically and without any real understanding of the external environment.

Grubhub and Russian self-driving startup Yandex are teaming up to use robots to deliver food on US college campuses. It represents the latest deal that envisions hundreds of six-wheeled self-driving robots that essentially act as roving lunchboxes in cities across the country. From a report: The robot-powered delivery service won't kick off until this fall when college students return to campus. Yandex, which is often described as Russia's Google, will operate the robots, as well as handle the entire food delivery process. Grubhub, which has partnerships with over 250 college campuses in the US, will serve as the platform for the delivery transactions.

Grubhub cited the cost savings it will get by eliminating the delivery worker from the equation as a potential benefit from the deal with Yandex -- though neither company disclosed the financial terms of the partnership. "We're excited to offer these cost-effective, scalable and quick food ordering and delivery capabilities to colleges and universities across the country that are looking to adapt to students' unique dining needs," said Brian Madigan, vice president of corporate and campus partners at Grubhub, in a statement. Yandex says that its delivery robots can navigate pavement, pedestrian areas and crosswalks, and reach campus areas not accessible by car. "Such functionality enables the robots to handle delivery tasks traditionally performed by people and provides efficient last-mile logistics automation," the company says.

The New York Times reports: When Kroger customers in Cincinnati shop online these days, their groceries may be picked out not by a worker in their local supermarket but by a robot in a nearby warehouse... And in the drive-through lane at Checkers near Atlanta, requests for Big Buford burgers and Mother Cruncher chicken sandwiches may be fielded not by a cashier in a headset, but by a voice-recognition algorithm. An increase in automation, especially in service industries, may prove to be an economic legacy of the pandemic. Businesses from factories to fast-food outlets to hotels turned to technology last year to keep operations running amid social distancing requirements and contagion fears. Now the outbreak is ebbing in the United States, but the difficulty in hiring workers — at least at the wages that employers are used to paying — is providing new momentum for automation...

[S]ome economists say the latest wave of automation could eliminate jobs and erode bargaining power, particularly for the lowest-paid workers, in a lasting way. "Once a job is automated, it's pretty hard to turn back," said Casey Warman, an economist at Dalhousie University in Nova Scotia who has studied automation in the pandemic... A working paper published by the International Monetary Fund this year predicted that pandemic-induced automation would increase inequality in coming years, not just in the United States but around the world. "Six months ago, all these workers were essential," said Marc Perrone, president of the United Food and Commercial Workers, a union representing grocery workers. "Everyone was calling them heroes. Now, they're trying to figure out how to get rid of them...."

The push toward automation goes far beyond the restaurant sector. Hotels, retailers, manufacturers and other businesses have all accelerated technological investments. In a survey of nearly 300 global companies by the World Economic Forum last year, 43 percent of businesses said they expected to reduce their work forces through new uses of technology... Daron Acemoglu of the Massachusetts Institute of Technology said that many of the technological investments had just replaced human labor without adding much to overall productivity. In a recent working paper, Professor Acemoglu and a colleague concluded that "a significant portion of the rise in U.S. wage inequality over the last four decades has been driven by automation" — and he said that trend had almost certainly accelerated in the pandemic. "If we automated less, we would not actually have generated that much less output but we would have had a very different trajectory for inequality," Professor Acemoglu said.
"We'll look back and say why didn't we do this sooner," fast-food franchisee Shana Gonzales told the Times after implementing an automated voice-recognition system that takes customers' orders. Gonzales added that she'd gladly hire human workers instead, but she just can't find them, and says she's even tried raising their starting pay rate — from $9 an hour to $10.

"Ms. Gonzales acknowledged she could fully staff her restaurants if she offered $14 to $15 an hour to attract workers. But doing so, she said, would force her to raise prices so much that she would lose sales — and automation allows her to take another course."

Westland Real Estate Group patrols its 1,000-unit apartment complex in Las Vegas with "a conical, bulky, artificial intelligence-powered robot" standing just over 5 feet tall, according to NBC News. Manufactured by Knightscope, the robot is equipped with four internal cameras capturing a constant 360-degree view, and can also scan and record license plates (as well as the MAC addresses of cellphones). But is it doing any good? As more government agencies and private sector companies resort to robots to help fight crime, the verdict is out about how effective they are in actually reducing it. Knightscope, which experts say is the dominant player in this market, has cited little public evidence that its robots have reduced crime as the company deploys them everywhere from a Georgia shopping mall to an Arizona development to a Nevada casino. Knightscope's clients also don't know how much these security robots help. "Are we seeing dramatic changes since we deployed the robot in January?" Dena Lerner, the Westland spokesperson said. "No. But I do believe it is a great tool to keep a community as large as this, to keep it safer, to keep it controlled."

For its part, Knightscope maintains on its website that the robots "predict and prevent crime," without much evidence that they do so. Experts say this is a bold claim. "It would be difficult to introduce a single thing and it causes crime to go down," said Ryan Calo, a law professor at the University of Washington, comparing the Knightscope robots to a "roving scarecrow." Additionally, the company does not provide specific, detailed examples of crimes that have been thwarted due to the robots.
The robots are expensive — they're rented out at about $70,000-$80,000 a year — but growth has stalled for the two years since 2018, and over four years Knightscope's total clients actually dropped from 30 to just 23. (Expenses have now risen — partly because the company is now doubling its marketing budget.)

There's also a thermal scanning feature, but Andrew Ferguson, a law professor at American University, still called these robots an "expensive version of security theater." And NBC News adds that KnightScope's been involved "in both tragic and comical episodes." In 2016, a K5 roaming around Stanford Shopping Center in Palo Alto, California, hit a 16-month-old toddler, bruising his leg and running over his foot. The company apologized, calling it a "freakish accident," and invited the family to visit the company's nearby headquarters in Mountain View, which the family declined. The following year, another K5 robot slipped on steps adjacent to a fountain at the Washington Harbour development in Washington, D.C., falling into the water. In October 2019, a Huntington Park woman, Cogo Guebara, told NBC News that she tried reporting a fistfight by pressing an emergency alert button on the HP RoboCop itself, but to no avail. She learned later the emergency button was not yet connected to the police department itself... [The northern California city] Hayward dispatched its robot in a city parking garage in 2018. The following year, a man attacked and knocked over the robot. Despite having clear video and photographic evidence of the alleged crime, no one was arrested, according to Adam Kostrzak, the city's chief information officer.
The city didn't renew its contract "due to the financial impact of Covid-19 in early 2020," the city's CIO tells NBC News. But the city had already spent over $137,000 on the robot over two years.

Boston Dynamics has been purchased by Hyundai in a deal valued at $1.1 billion. According to Motherboard, the deal "sees Hyundai assume an 80 percent controlling stake in the robot company. Softbank will retain a 20 percent stake." From the report: It is hard to tell what Hyundai wants out of Boston Dynamics from the press release, which is laden with technobabble. Robots in car manufacturing are nothing new, but Hyundai says the acquisition is "another major step toward its strategic transformation into a Smart Mobility Solution Provider" such as "autonomous driving, artificial intelligence (AI), Urban Air Mobility (UAM), smart factories and robots," which seems to speak to the company's ambitions beyond car manufacturing. Hyundai says it hopes to "develop advanced technologies that enhance people's lives and promote safety, thereby realizing the progress for humanity."

Apparently, the "progress of humanity" means a lot less of it. To celebrate the purchase, Hyundai released a bizarre hype video featuring a seeing-eye robot dog, a nurse robot dog with a tablet mounted on its head that allows the patient to nod at a doctor who is somewhere else, and a teen dancing with a robot in the street. In other words, Hyundai envisions a lonely future in which social cohesion between humans has broken down and robots are our only friends. That's all bad enough, but why anyone would want a seeing eye robot dog instead of a real dog is beyond comprehension.

Long-time Slashdot reader cusco shares an interesting report from IEEE Spectrum: In 2017, we first wrote about the Chinese startup Unitree Robotics, which had the goal of "making legged robots as popular and affordable as smartphones and drones." Relative to the cost of other quadrupedal robots (like Boston Dynamics' $74,000 Spot), Unitree's quadrupeds are very affordable, with their A1 costing under $10,000 when it became available in 2020. This hasn't quite reached the point of consumer electronics that Unitree is aiming for, but they've just gotten a lot closer: now available is the Unitree Go1, a totally decent looking small size quadruped that can be yours for an astonishingly low $2700.

Speedy, good looking gait, robust, and a nifty combination of autonomous human-following and obstacle avoidance... There are three versions of the Go1: the $2700 base model Go1 Air, the $3500 Go1, and the $8500 Go1 Edu... The top of the line Edu model offers higher end computing, 2kg more payload (up to 5kg), as well as foot-force sensors, lidar, and a hardware extension interface and API access... Battery life is a big question — the video seems to suggest that the Go1 is capable of a three-kilometer, 20-minute jog, and then some grocery shopping and a picnic, all while doing obstacle avoidance and person following and with an occasional payload.
Unitree later provided the reporter more detailed specs:

• The battery life of the robot while jogging is about 1 hour
• It weighs 12kg
• The Super Sensory System includes five wide-angle stereo depth cameras, hypersonic distance sensors, and an integrated processing system
• It's running at 16 core CPU and a 1.5 tflop GPU

Check out this video footage of the sleek Mayflower 400 slicing through the water, hoping to retrace the historic 1620 journey of the famous ship which carried pilgrims to America. Unfortunately, unlike the real Mayflower, this robotic 21st-century doppelganger "had to turn back Friday to fix a mechanical problem," reports the Associated Press: Nonprofit marine research organization ProMare, which worked with IBM to build the autonomous ship, said it made the decision to return to base "to investigate and fix a minor mechanical issue" but hopes to be back on the trans-Atlantic journey as soon as possible.

With no humans on board the ship, there's no one to make repairs while it's at sea.

Piloted by artificial intelligence technology, the 50-foot (15-meter) Mayflower Autonomous Ship began its trip early Tuesday, departing from Plymouth, England, and spending some time off the Isles of Scilly before it headed for deeper waters.

It was supposed to take up to three weeks to reach Provincetown on Cape Cod before making its way to Plymouth, Massachusetts. If successful, it would be the largest autonomous vessel to cross the Atlantic.

The BBC reports: China's Zhurong rover has sent back a batch of new images from Mars — including a "selfie". The robot, which landed in May, positioned a wireless camera on the ground and then rolled back a short distance to take the snap. To Zhurong's right is the rocket-powered platform that brought the six-wheeled vehicle to a soft touchdown. Both display prominent Chinese flags...

It weighs some 240kg. A tall mast carries cameras to take pictures and aid navigation; five additional instruments will investigate the mineralogy of local rocks and the general nature of the environment, including the weather. Like the current American rovers (Curiosity and Perseverance), Zhurong has a laser tool to zap rocks to assess their chemistry. It also has a radar to look for sub-surface water-ice - a capability it shares with Perseverance.
Slashdot reader InfiniteZero writes that the mission's "full resolution images including a 360 panoramic view of the landing site, can be found at the official CNSA website."

New submitter DaveV1.0 shares a report from CNBC: At 10 McDonald's locations in Chicago, workers aren't taking down customers' drive-thru orders for McNuggets and french fries -- a computer is, CEO Chris Kempczinski said Wednesday. Kempczinski said the restaurants using the voice-ordering technology are seeing about 85% order accuracy. Only about a fifth of orders need to be a taken by a human at those locations, he said, speaking at Alliance Bernstein's Strategic Decisions conference.

In 2019, under former CEO Steve Easterbrook, McDonald's went on a spending spree, snapping up restaurant tech. One of those acquisitions was Apprente, which uses artificial intelligence software to take drive-thru orders. Kempczinski said the technology will likely take more than one or two years to implement. "Now there's a big leap from going to 10 restaurants in Chicago to 14,000 restaurants across the U.S., with an infinite number of promo permutations, menu permutations, dialect permutations, weather — and on and on and on," he said. Another challenge has been training restaurant workers to stop themselves from jumping in to help.

18-inch tall robots on four wheels zipping across city sidewalks "stopped people in their tracks as they whipped out their camera phones," reports the Florida Sun-Sentinel.

"The bots' mission: To deliver restaurant meals cheaply and efficiently, another leap in the way food comes to our doors and our tables." The semiautonomous vehicles were engineered by Kiwibot, a company started in 2017 to game-change the food delivery landscape...

In May, Kiwibot sent a 10-robot fleet to Miami as part of a nationwide pilot program funded by the Knight Foundation. The program is driven to understand how residents and consumers will interact with this type of technology, especially as the trend of robot servers grows around the country. And though Broward County is of interest to Kiwibot, Miami-Dade County officials jumped on board, agreeing to launch robots around neighborhoods such as Brickell, downtown Miami and several others, in the next couple of weeks... "Our program is completely focused on the residents of Miami-Dade County and the way they interact with this new technology. Whether it's interacting directly or just sharing the space with the delivery bots," said Carlos Cruz-Casas, with the county's Department of Transportation...

Remote supervisors use real-time GPS tracking to monitor the robots. Four cameras are placed on the front, back and sides of the vehicle, which the supervisors can view on a computer screen. [A spokesperson says later in the article "there is always a remote and in-field team looking for the robot."] If crossing the street is necessary, the robot will need a person nearby to ensure there is no harm to cars or pedestrians. The plan is to allow deliveries up to a mile and a half away so robots can make it to their destinations in 30 minutes or less.
Earlier Kiwi tested its sidewalk-travelling robots around the University of California at Berkeley, where at least one of its robots burst into flames. But the Sun-Sentinel reports that "In about six months, at least 16 restaurants came on board making nearly 70,000 deliveries...

"Kiwibot now offers their robotic delivery services in other markets such as Los Angeles and Santa Monica by working with the Shopify app to connect businesses that want to employ their robots." But while delivery fees are normally $3, this new Knight Foundation grant "is making it possible for Miami-Dade County restaurants to sign on for free."

A video shows the reactions the sidewalk robots are getting from pedestrians on a sidewalk, a dog on a leash, and at least one potential restaurant customer looking forward to no longer having to tip human food-delivery workers.

Instacart has an audacious plan to replace its army of gig shoppers with robots -- part of a long-term strategy to cut costs and put its relationship with supermarket chains on a sustainable footing. From a report: The plan, detailed in documents reviewed by Bloomberg, involves building automated fulfillment centers around the U.S., where hundreds of robots would fetch boxes of cereal and cans of soup while humans gather produce and deli products. Some facilities would be attached to existing grocery stores while larger standalone centers would process orders for several locations, according to the documents, which were dated July and December.

Despite working on the strategy for more than a year, however, the company has yet to sign up a single supermarket chain. Instacart had planned to begin testing the fulfillment centers later this year, the documents show. But the company has fallen behind schedule, according to people familiar with the situation. And though the documents mention asking several automation providers to build the technology, Instacart hasn't settled on any, said the people, who requested anonymity to discuss a private matter. In February, the Financial Times reported on elements of the strategy and said Instacart in early 2020 sent out requests for proposals to five robotics companies.

An Instacart spokeswoman said the company was busy buttressing its operations during the pandemic, when it signed up 300,000 new gig workers in a matter of weeks, bringing the current total to more than 500,000. But the delays in getting the automation strategy off the ground could potentially undermine plans to go public this year. Investors know robots will play a critical role in modernizing the $1.4 trillion U.S. grocery industry.

"Robots and artificial intelligence will replace workers on Australia's first fully automated farm," reports Australia's national public broadcaster ABC.

The total cost of the farm's upgrade? $20 million. Charles Sturt University in Wagga Wagga will create the "hands-free farm" on a 1,900-hectare property to demonstrate what robots and artificial intelligence can do without workers in the paddock... The farm will use robotic tractors, harvesters, survey equipment and drones, artificial intelligence that will handle sowing, dressing and harvesting, new sensors to measure plants, soils and animals and carbon management tools to minimise the carbon footprint.

The farm is already operated commercially and grows a range of broadacre crops, including wheat, canola, and barley, as well as a vineyard, cattle and sheep.

The New York Police Department said this week that it will stop using the "Digidog," a four-legged robot occasionally deployed for recon in dangerous situations. NYPD officials confirmed in a statement it had terminated its contract and will return the dog to vendor Boston Dynamics. Last December, the agency leased the Digidog, nicknamed Spot, for $94,000. From a report: John Miller, the police department's deputy commissioner for intelligence and counterterrorism, told The New York Times that the contract was "a casualty of politics, bad information, and cheap sound bites." Miller bemoaned the role of bad press in the backlash, but in many ways the NYPD's own actions were a blueprint for how not to introduce new tech. And, for activists, how to effectively agitate for banning unwanted technologies.

In truth, it wasn't just sound bites that doomed Spot. New Yorkers didn't want it. In February, the NYPD used Spot to defuse a hostage situation in the Bronx. When video of the device went viral, its flexible legs and camera-for-a-head design spooked people. The robot is quadrupedal but doesn't actually look like a dog. A more immediate comparison is the armed robots featured in a postapocalyptic episode of Black Mirror. This comparison spread rapidly on social media. The NYPD's secrecy worked against it: There was no public comment process for Spot, and residents hadn't known to expect to see robot-dogs respond to hostage situations. The NYPD had exactly this opportunity, months earlier, when it had to disclose both the price and governing policies for all surveillance devices as defined by the city's Public Oversight of Surveillance Technology (POST) Act. Instead, the agency included a passing reference to Spot in a larger section on "situational awareness cameras," with no images.

Legal services startup DoNotPay is best known for its army of "robot lawyers" -- automated bots that tackle tedious online tasks like canceling TV subscriptions and requesting refunds from airlines. Now, the company has unveiled a new tool it says will help shield users' photos from reverse image searches and facial recognition AI. The Verge reports: It's called Photo Ninja and it's one of dozens of DoNotPay widgets that subscribers can access for $36 a year. Photo Ninja operates like any image filter. Upload a picture you want to shield, and the software adds a layer of pixel-level perturbations that are barely noticeable to humans, but dramatically alter the image in the eyes of roving machines. The end result, DoNotPay CEO Joshua Browder tells The Verge, is that any image shielded with Photo Ninja yields zero results when run through search tools like Google image search or TinEye.

The tool also fools popular facial recognition software from Microsoft and Amazon with a 99 percent success rate. This, combined with the anti-reverse-image search function, makes Photo Ninja handy in a range of scenarios. You might be uploading a selfie to social media, for example, or a dating app. Running the image through Photo Ninja first will prevent people from connecting this image to other information about you on the web. Browder is careful to stress, though, that Photo Ninja isn't guaranteed to beat every facial recognition tool out there.

Hmmmmmm writes: China plans to launch its next robot lunar lander in 2024, and it will carry equipment manufactured by scientists from France, Sweden, Italy, and Russia, Hu Hao, the program's chief designer, told the Xinhua News Agency on Saturday. The country aims to position the lander, named Chang'e 6, near the lunar south pole where it will collect samples, per the official Xinhua News Agency.

The Chang'e 6 lander is part of China's ongoing mission to successfully return moon samples back home "for comprehensive analysis and research," Hu said at a conference, Associated Press reported.

For the 2024 mission, The China National Space Administration has invited scientists from around the world to take part in the program, offering to transport solicited payloads into space. So far, four payloads designed by the international scientists have been preliminarily chosen, the Xinhua News Agency reported.

destinyland writes: Mystery Science Theater 3000 will be coming back — with a new home online. Though Netflix didn't pick them up for another season after 2019, "We still want to keep making new episodes," series creator Joel Hodgson explains in an online video on Kickstarter. (Also available through the URL MakeMoreMST3K.com.)

And with 12 days left to go, 18,969 online fans have already pledged $3,348,705, funding six new episodes...

But in addition the first $2 million funded the creation of the Gizmoplex, "our very own virtual online theatre," while the first stretch goal was also funded — the creation of MST3K apps for Android, iOS, and streaming services like AppleTV and Roku. "I'm tired of other people deciding if our show lives or dies," explains Crow T. Robot in the Kickstarter video. "I wanna do that." New host Jonah Heston adds, "If we want MST3K to keep going long-term, maybe networks aren't the most reliable option. Maybe it should be up to the fans to decide how long we keep going..."

Their next stretch goal of $4.4 million would fund three more episodes, but will also allow them to invite backers to the Gizmoplex for live monthly events, "for at least a year." And if they reach their goal of $5.5 million, they'll fund three more episodes — so an entire 12-episode season — as well as 12 short-subject films.

The ultimate hope is to host frequent live screenings, premieres, and community events in the Gizmoplex — while fans can even host their own MST3K watch parties whenever they want. And their Kickstarter page even suggests they might someday extend the Gizmoplex into virtual reality (accessible on computer and headsets).
I still remember how back in 2008 Joel Hodgson answered questions from Slashdot readers. "I've been a fan so long, I can't even remember when," posted CmdrTaco.

According to Sacramento CBS affiliate KOVR-TV, Yana Sydnor called the police to report a possible home invasion. Turns out, it was a robovac that her son turned on before leaving for the weekend. Android Police reports: At 1 a.m., she and her 2-year-old daughter woke up to loud booms coming from her stairs disrupting her meditation music. She texted her friends about the sounds before they quickly responded, urging her to call 911. "I hear someone walking down my stairs, so it's like boom, boom, boom, boom, boom," Sydnor recalls telling the dispatcher. Desperate to exit the house and avoid a run-in with the invader, she ran to the bathroom, put her daughter in the tub, and thought about grabbing a ladder to get them both outside to ground level.

Officers arrived within 10 minutes of Sydnor's call. They rammed the front door wide open only to find a poor robovac, fresh from a tumble down a flight of stairs. "My son turned on the vacuum cleaner because he didn't want to do chores before he left for the weekend," she explained to the reporter after a moment of exasperated silence. The vacuum hadn't been used for 2 years and, even after the fall, it still works. We couldn't make out the make and model of the robovac, so we don't quite know if it could stop itself from going over the ledge much less what exactly happened in this case if it did have the ability.

William Robinson shares a report: The growing list of "firsts" for Perseverance, NASA's newest six-wheeled robot on the Martian surface, includes converting some of the Red Planet's thin, carbon dioxide-rich atmosphere into oxygen. A toaster-size, experimental instrument aboard Perseverance called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) accomplished the task. The test took place April 20, the 60th Martian day, or sol, since the mission landed Feb. 18. While the technology demonstration is just getting started, it could pave the way for science fiction to become science fact -- isolating and storing oxygen on Mars to help power rockets that could lift astronauts off the planet's surface. Such devices also might one day provide breathable air for astronauts themselves. MOXIE is an exploration technology investigation -- as is the Mars Environmental Dynamics Analyzer (MEDA) weather station -- and is sponsored by NASA's Space Technology Mission Directorate (STMD) and Human Exploration and Operations Mission Directorate. "This is a critical first step at converting carbon dioxide to oxygen on Mars," said Jim Reuter, associate administrator for STMD. "MOXIE has more work to do, but the results from this technology demonstration are full of promise as we move toward our goal of one day seeing humans on Mars. Oxygen isn't just the stuff we breathe. Rocket propellant depends on oxygen, and future explorers will depend on producing propellant on Mars to make the trip home." For rockets or astronauts, oxygen is key, said MOXIE's principal investigator, Michael Hecht of the Massachusetts Institute of Technology's Haystack Observatory.

Researchers have developed a tool that can design complex DNA robots and nanodevices in minutes instead of days. Phys.Org reports: In a paper published today in the journal Nature Materials, researchers from The Ohio State University -- led by former engineering doctoral student Chao-Min Huang -- unveiled new software they call MagicDNA. The software helps researchers design ways to take tiny strands of DNA and combine them into complex structures with parts like rotors and hinges that can move and complete a variety of tasks, including drug delivery. One advantage is that it allows researchers to carry out the entire design truly in 3-D. Earlier design tools only allowed creation in 2-D, forcing researchers to map their creations into 3-D. That meant designers couldn't make their devices too complex.

The software also allows designers to build DNA structures "bottom up" or "top down." In "bottom up" design, researchers take individual strands of DNA and decide how to organize them into the structure they want, which allows fine control over local device structure and properties. But they can also take a "top down" approach where they decide how their overall device needs to be shaped geometrically and then automate how the DNA strands are put together. Combining the two allows for increasing complexity of the overall geometry while maintaining precise control over individual component properties. Another key element of the software is that it allows simulations of how designed DNA devices would move and operate in the real world.
