Stretch is a new robot from Boston Dynamics that can move approximately 800 heavy boxes per hour. As IEEE Spectrum reports, it's part of "a new generation of robots with the intelligence and flexibility to handle the kind of variation that people take in stride." From the report: Stretch's design is somewhat of a departure from the humanoid and quadrupedal robots that Boston Dynamics is best known for, such as Atlas and Spot. With its single massive arm, a gripper packed with sensors and an array of suction cups, and an omnidirectional mobile base, Stretch can transfer boxes that weigh as much as 50 pounds (23 kilograms) from the back of a truck to a conveyor belt at a rate of 800 boxes per hour. An experienced human worker can move boxes at a similar rate, but not all day long, whereas Stretch can go for 16 hours before recharging. And this kind of work is punishing on the human body, especially when heavy boxes have to be moved from near a trailer's ceiling or floor. "Truck unloading is one of the hardest jobs in a warehouse, and that's one of the reasons we're starting there with Stretch," says Kevin Blankespoor, senior vice president of warehouse robotics at Boston Dynamics. Blankespoor explains that Stretch isn't meant to replace people entirely; the idea is that multiple Stretch robots could make a human worker an order of magnitude more efficient. "Typically, you'll have two people unloading each truck. Where we want to get with Stretch is to have one person unloading four or five trucks at the same time, using Stretches as tools." All Stretch needs is to be shown the back of a trailer packed with boxes, and it'll autonomously go to work, placing each box on a conveyor belt one by one until the trailer is empty. People are still there to make sure that everything goes smoothly, and they can step in if Stretch runs into something that it can't handle, but their full-time job becomes robot supervision instead of lifting heavy boxes all day. Stretch is optimized for moving boxes, a task that's required throughout a warehouse. Boston Dynamics hopes that over the longer term the robot will be flexible enough to put its box-moving expertise to use wherever it's needed. In addition to unloading trucks, Stretch has the potential to unload boxes from pallets, put boxes on shelves, build orders out of multiple boxes from different places in a warehouse, and ultimately load boxes onto trucks, a much more difficult problem than unloading due to the planning and precision required. [...] Boston Dynamics spent much of 2021 turning Stretch from a prototype, built largely from pieces designed for Atlas and Spot, into a production-ready system that will begin shipping to a select group of customers in 2022, with broader sales expected in 2023. For Blankespoor, that milestone will represent just the beginning. He feels that such robots are poised to have an enormous impact on the logistics industry.

New York-based firm Pliant Energy Systems is building a marine system reminiscent of the cuttlefish with its rippling underwater motion, a report from The Economist reveals. The company's biomimetic machine, called Velox, is based on the principle that propellers are nowhere near as efficient as the fins of sea creatures that are prevalent in nature. Interesting Engineering reports: Unlike propellers, fins and flippers can extend around a sea creature, meaning more propulsion without the need for a large protruding propeller that could get caught or damaged by hitting the seabed. Fins are also flexible, meaning that if they do come in contact with any other object in the sea, they are less likely to get damaged. In an interview with The Economist, an ex-marine biologist and founder of Pliant Energy Systems, Benjamin Pietro Filardo, explained how he is designing submersible machines that are propelled using flexible fin-like materials. He said Velox will produce approximately three times as much thrust per unit energy as the average propeller of a small boat. The system can travel underwater and even come out onto land, using its fins almost like robotic legs. The video below shows Velox skating on ice and swimming in a pool. Filardo showed his new design to America's Office of Naval Research, leading them to commission a new iteration, called C-Ray, that will be faster and lighter than Velox. C-Ray also won't be tethered, unlike Velox, which is currently controlled via a cable. Autonomous swarms of the machine could eventually be used for missions such as undersea patrols, mine removal, and deepsea exploration and monitoring. [...] Filardo said the system has great potential for scalability, giving the blue whale as an example of a massive sea mammal that uses fins for propulsion. Impressively, he also revealed that he is also working on a concept that would allow his system to moor itself, and then use the undulations of its fins, thanks to the sea current, to recharge. A lot of testing is still needed, but if Filardo's system delivers on its promise, we might eventually see giant mechanical sea beasts silently gliding through the oceans.

Tyson Foods plans to spend more than $1.3 billion to increase automation in meat plants over the next three years, Chief Executive Donnie King said on Thursday, as a U.S. labor shortage has limited production while demand is booming. Reuters reports: Meat processors have been unable to find enough workers for the past two years due to the tight labor market and health concerns during the COVID-19 pandemic. Tyson expects to boost production and reduce labor costs by expanding automation, with cumulative savings of more than $450 million projected by fiscal year 2024, King said on a webcast for investors. The company will increasingly use machines, instead of people, to debone chicken, one of its most labor-intensive jobs and a position with high turnover, said David Bray, group president of Tyson's poultry division. A capital investment of $500 million in the area through fiscal year 2024 will generate labor savings equal to more than 2,000 jobs, he said. Profitability in Tyson's chicken unit has declined partly due to the labor shortage and because processing plants are operating below full capacity, Bray said. "We are not servicing our customers to the degree that they expect us to," Bray said.

For 32 years a human named Andy Chanley has been a radio announcer (now working afternoon's at Southern California's 88.5 KCSN), Reuters reports. But now.... "I may be a robot, but I still love to rock," says the robot DJ named ANDY, derived from Artificial Neural Disk-JockeY, in Chanley's voice, during a demonstration for Reuters where the voice was hard to distinguish from a human disc jockey. Our phones, speakers and rice cookers have been talking to us for years, but their voices have been robotic. Seattle-based AI startup WellSaid Labs says it has finessed the technology to create over 50 real human voice avatars like ANDY so far, where the producer just needs to type in text to create the narration.... Martín Ramírez, head of growth at WellSaid, said once the voice avatars are created, WellSaid manages the commercial agreements according to the voice owner's requests. WellSaid voice avatars are doing more than DJ work. They are used in corporate training material or even to read audiobooks, said Ramirez. The article points out that while (human) announcer Andy Chanley was recording his voice, he discovered he has Stage 2 lymphoma. While he eventually recovered, Chanley liked knowing that there was also another way that the sound of his voice could still be supporting his family — and that his grandchildren could hear the sound of his voice.

A U.K.-based company Engineered Arts has developed a humanoid robot that can display human-like expressions with ease. Interesting Engineering reports: In a short video released on YouTube, the company shows off its most advanced humanoid, dubbed Ameca, which is initially a platform for testing robotic technologies. As is seen in the video [...], the humanoid appears to have woken up in a robotic laboratory while an actual human is busy working in the background. The robot moves its arms, shows a flurry of expressions in a matter of seconds, and even expresses amazement at how its hands and fingers move fluidly before looking at the camera quite surprised. The teaser is a sufficient demonstration of what the robot can do when it comes to the upper half of the body. Its lower half though is quite non-functional at the moment. For a humanoid robot, Ameca still can't walk, the Engineered Arts website says. Even though the company has carried out research on this, it hasn't transferred the learnings to the robot yet. [...] Engineered Arts uses a modular architecture for its building its robots. So, upgrades to both, software and hardware components can be made without having to purchase a new robot altogether. So, sooner or later, Ameca will walk too. Ameca is powered by Engineered Arts' Tritium operating system that allows companies engaged in the development of robotics to test their technologies. Whether it is artificial intelligence or machine learning technology that companies or startups are developing, they can test and even demonstrate their tech in front of a live audience using Ameca. According to its website, Engineered Arts can even rent out Ameca for expos or live TV discussions.

The US scientists who created the first living robots say the life forms, known as xenobots, can now reproduce -- and in a way not seen in plants and animals. CNN reports: Formed from the stem cells of the African clawed frog (Xenopus laevis) from which it takes its name, xenobots are less than a millimeter (0.04 inches) wide. The tiny blobs were first unveiled in 2020 after experiments showed that they could move, work together in groups and self-heal. Now the scientists that developed them at the University of Vermont, Tufts University and Harvard University's Wyss Institute for Biologically Inspired Engineering said they have discovered an entirely new form of biological reproduction different from any animal or plant known to science. [T]hey found that the xenobots, which were initially sphere-shaped and made from around 3,000 cells, could replicate. But it happened rarely and only in specific circumstances. The xenobots used "kinetic replication" -- a process that is known to occur at the molecular level but has never been observed before at the scale of whole cells or organisms [...]. With the help of artificial intelligence, the researchers then tested billions of body shapes to make the xenobots more effective at this type of replication. The supercomputer came up with a C-shape that resembled Pac-Man, the 1980s video game. They found it was able to find tiny stem cells in a petri dish, gather hundreds of them inside its mouth, and a few days later the bundle of cells became new xenobots. The xenobots are very early technology -- think of a 1940s computer -- and don't yet have any practical applications. However, this combination of molecular biology and artificial intelligence could potentially be used in a host of tasks in the body and the environment, according to the researchers. This may include things like collecting microplastics in the oceans, inspecting root systems and regenerative medicine. While the prospect of self-replicating biotechnology could spark concern, the researchers said that the living machines were entirely contained in a lab and easily extinguished, as they are biodegradable and regulated by ethics experts. "Most people think of robots as made of metals and ceramics but it's not so much what a robot is made from but what it does, which is act on its own on behalf of people," said Josh Bongard, a computer science professor and robotics expert at the University of Vermont and lead author of the study, writing in the Proceedings of the National Academy of Sciences. "In that way it's a robot but it's also clearly an organism made from genetically unmodified frog cell." "The AI didn't program these machines in the way we usually think about writing code. It shaped and sculpted and came up with this Pac-Man shape," Bongard said. "The shape is, in essence, the program. The shape influences how the xenobots behave to amplify this incredibly surprising process."

The company announced today that its Everyday Robots Project -- a team within its experimental X labs dedicated to creating "a general-purpose learning robot" -- has moved some of its prototype machines out of the lab and into Google's Bay Area campuses to carry out some light custodial tasks. The Verge reports: "We are now operating a fleet of more than 100 robot prototypes that are autonomously performing a range of useful tasks around our offices," said Everyday Robot's chief robot officer Hans Peter Brondmo in a blog post. "The same robot that sorts trash can now be equipped with a squeegee to wipe tables and use the same gripper that grasps cups can learn to open doors." These robots in question are essentially arms on wheels, with a multipurpose gripper on the end of a flexible arm attached to a central tower. There's a "head" on top of the tower with cameras and sensors for machine vision and what looks like a spinning lidar unit on the side, presumably for navigation. As Brondmo indicates, these bots were first seen sorting out recycling when Alphabet debuted the Everyday Robot team in 2019. The big promise that's being made by the company (as well as by many other startups and rivals) is that machine learning will finally enable robots to operate in "unstructured" environments like homes and offices.

An anonymous reader quotes a report from CNN: Companies in North America added a record number of robots in the first nine months of this year as they rushed to speed up assembly lines and struggled to add human workers. Factories and other industrial users ordered 29,000 robots, 37% more than during the same period last year, valued at $1.48 billion, according to data compiled by the industry group the Association for Advancing Automation. That surpassed the previous peak set in the same time period in 2017, before the global pandemic upended economies. The rush to add robots is part of a larger upswing in investment as companies seek to keep up with strong demand, which in some cases has contributed to shortages of key goods. At the same time, many firms have struggled to lure back workers displaced by the pandemic and view robots as an alternative to adding human muscle on their assembly lines. Robots also continue to push into more corners of the economy. Auto companies have long bought most industrial robots. But in 2020, combined sales to other types of businesses surpassed the auto sector for the first time -- and that trend continued this year. In the first nine months of the year, auto-related orders for robots grew 20% to 12,544 units, according to A3, while orders by non-automotive companies expanded 53% to 16,355.

Quadrupedal robots are one of the most interesting developments in robotics in recent years. They're small, nimble, and able to traverse environments that frustrate wheeled machines. So, of course, it was only a matter of time until someone put a gun on one. From a report: The image in the linked story shows a quadrupedal robot -- a Vision 60 unit built by US firm Ghost Robotics -- that's been equipped with a custom gun by small-arms specialists Sword International. It seems the gun itself (dubbed the SPUR or "special purpose unmanned rifle") is designed to be fitted onto a variety of robotic platforms. It has a 30x optical zoom, thermal camera for targeting in the dark, and an effective range of 1,200 meters. What's not clear is whether or not Sword International or Ghost Robotics are currently selling this combination of gun and robot. But if they're not, it seems they will be soon. As the marketing copy on Sword's website boasts: "The SWORD Defense Systems SPUR is the future of unmanned weapon systems, and that future is now."

Italian winemakers have increasingly relied on migrant workers for the autumn harvest, but travel restrictions and soaring wage costs are pushing many to turn to machines. From a report: Last year's grape harvest was a harrowing scramble at Mirko Cappelli's Tuscan vineyard. With the Italian border closed because of the pandemic, the Eastern European workers he had come to rely on couldn't get into the country. The company he had contracted to supply grape pickers had no one to offer him. He ultimately found just enough workers to bring the grapes in on time. So, this year Mr. Cappelli made sure he wouldn't face the same problem: He spent â85,000, equivalent to $98,000, on a grape-harvesting machine. The coronavirus pandemic is pushing the wine industry toward automation. Covid-related travel restrictions left severe shortages of agricultural workers last year, as Eastern Europeans and North Africans were unable to reach fields in Western Europe. Though the shortages have eased this year, the difficulty of finding workers has accelerated the shift, which was already under way across the agricultural sector. While harvests of some crops, like soybeans and corn, are already heavily automated, winemakers have been slower to make the switch. Vintners debate whether automated harvesting is more likely to damage grapes, which can affect the quality of the wine. The cost is a deterrent for many small farmers. Some European regions even ban machine harvesting. For many vintners in Europe and the U.S., however, the difficulty of finding workers -- a problem they say had grown steadily for years but became acute during the pandemic -- has pushed them to take the robot plunge. It is a change that will outlast the pandemic and could shift longstanding migration patterns that bring tens of thousands of foreign workers to Italy, France and Spain for agricultural harvests each year. Ritano Baragli, president of Cantina Sociale colli Fiorentini Valvirgilio, a winemaker's group in Tuscany, said it has been getting harder to find pickers for several years, as locals increasingly shun the physically demanding, low-paid, short-term work while the demand for pickers has increased. But last year was the worst labor shortage of his half-century career in wine. Use of harvesting machines among the group's members increased 20% this year in response, he said.

em1ly shares a report from Motherboard: Amazon's new robot called Astro is designed to track the behavior of everyone in your home to help it perform its surveillance and helper duties, according to leaked internal development documents and video recordings of Astro software development meetings obtained by Motherboard. The system's person recognition system is heavily flawed, according to two sources who worked on the project. The documents, which largely use Astro's internal codename "Vesta" for the device, give extensive insight into the robot's design, Amazon's philosophy, how the device tracks customer behavior as well as flow charts of how it determines who a "stranger" is and whether it should take any sort of "investigation activity" against them. The meeting document spells out the process in a much blunter way than Amazon's cutesy marketing suggests. "[Astro] slowly and intelligently patrols the home when unfamiliar person are around, moving from scan point to scan point (the best location and pose in any given space to look around) looking and listening for unusual activity," one of the files reads. "Vesta moves to a predetermined scan point and pose to scan any given room, looking past and over obstacles in its way. Vesta completes one complete patrol when it completes scanning all the scan point on the floorplan." [...] Developers who worked on Astro say the versions of the robot they worked on did not work well. "Astro is terrible and will almost certainly throw itself down a flight of stairs if presented the opportunity. The person detection is unreliable at best, making the in-home security proposition laughable," a source who worked on the project said. "The device feels fragile for something with an absurd cost. The mast has broken on several devices, locking itself in the extended or retracted position, and there's no way to ship it to Amazon when that happens." "They're also pushing it as an accessibility device but with the masts breaking and the possibility that at any given moment it'll commit suicide on a flight of stairs, it's, at best, absurdist nonsense and marketing and, at worst, potentially dangerous for anyone who'd actually rely on it for accessibility purposes," the source said.

Amazon announced its long-rumored $999 Astro home robot on Tuesday. CNBC: I had a chance to check it out in a demo with Amazon last week and wanted to share a few thoughts on what Astro is, what it can and can't do and why Amazon decided to build a home robot. Astro seems like a strange gadget for Amazon to launch. The company is best known as an online store. And most of its operating profit comes from its AWS cloud business. Notably, Astro is a "Day 1 Edition" product, which means it won't be sold to everyone at first. [...] Astro is about the size of a small dog. It roams around your house on three wheels, including two big ones that prevent it from getting stuck and a smaller one for rotating. It has a camera that rises up on a 42-inch arm that can keep an eye on your home as Astro patrols while you're away. It can follow you around and play music or display TV shows on its 10-inch touchscreen. It can recognize faces (if you want it to) so you can load up two sodas in the back storage compartment and tell Astro to go to someone in the living room. Astro is like a combo of lots of Amazon's other gadgets placed on wheels. The cameras can be used for home security or for video chat, sort of combining Amazon's Ring cameras with its Echo Show smart screens. The cameras are also used to create a map of your house when you set Astro up for the first time. You can talk to Astro much like you'd talk to an Echo or Alexa (you can change the name to Alexa if you want) to get sports scores or the weather. And you can play movies or TV shows like you would on an Amazon tablet or Fire TV.

CNET's Roadshow reports that a safety-oriented version of Boston Dynamics' headless dog-shaped robot "Spot" will begin patrolling a Kia plant in South Korea, "to survey industrial areas remotely and help identify issues before they happen." For example, Spot's new thermal camera and 3D lidar (courtesy of Hyundai's technology chest) can identify personnel near machinery with high temperatures. In this case, our robotic canine friend may be able to pinpoint a fire hazard before a human does. The robot can be controlled remotely by human operators as well, and send potential alarms for hazards and notify plant management of a situation. Hyundai also plans to have the robot accompany night patrols to create a safer environment. With new gadgetry attached to Spot, including the latest artificial intelligence that helps it understand if doors are open or closed, the automaker believes the robot can play a big part in security... All of Spot's new tasks are part of a pilot program so Hyundai can see if there's value in deploying additional Spot-based, robotic security dogs in other plants. Hyundai's motor group has released a slick video showing the security robot in action. It ends with the words "Robotics for Humanity."

"If you're wandering around Singapore anytime soon, take some time to wave hi to your friendly neighborhood snitch bot," writes Gizmodo: Singapore's Home Team Science and Technology Agency (HTX) will be deploying two robots named "Xavier" that the agency says use cameras with a 360-degree field of vision and analytics software to detect "undesirable social behaviors" in real time. First reported by Business Insider, the robots are designed to detect activities such as public smoking, violation of pandemic restrictions (i.e., groups of more than five people), and illegally selling goods on the street. Other behaviors the agency said the robots can snitch on include the use of motorized vehicles or motorcycles on pedestrian walkways and "improperly parked bicycles." The Xavier robots roll around on a "patrol route pre-configured in advance by public officers," though they can deviate as necessary to avoid slamming into pedestrians or other obstacles. The plan is for the two robots to relay reports of such activity to a central police hub as well as confront violators directly with warning messages, with the first three weeks of deployment starting on Sept. 5 in Toa Payoh Central. The three weeks are a "trial period," reports ZDNet. But they also note that the program includes "an interactive dashboard where public officers can receive real-time information from and be able to monitor and control multiple robots simultaneously." One official said in a public statement that "The deployment of ground robots will help to augment our surveillance and enforcement resources." ZDNet offers some context: Seeing robots being used in Singapore is not uncommon. Last year, Singapore deployed Boston Dynamics' four-legged droids, dubbed Spot, to its parks, garden, and nature reserves to remind people about social distancing. A fleet of Lightstrike robots was then rolled out at one of Singapore's general hospitals in a bid to thoroughly disinfect hospital rooms of pathogens. More recently in May, the Singapore government launched a one-year trial of using autonomous robots to facilitate on-demand food and grocery deliveries.

A robot called CIMON-2 (short for Crew Interactive Mobile Companion) has received a software update that will enable it to perform more complex tasks with a new human crewmate later this year. Space.com reports: The cute floating sphere with a cartoon-like face has been stored at the space station since the departure of the European Space Agency's (ESA) astronaut Luca Parmitano in February 2020. The robot will wake up again during the upcoming mission of German astronaut Matthias Maurer, who will arrive at the orbital outpost with the SpaceX Crew-3 Dragon mission in October. In the year and a half since the end of the last mission, engineers have worked on improving CIMON's connection to Earth so that it could provide a more seamless service to the astronauts, CIMON project manager Till Eisenberg at Airbus, which developed the intelligent robot together with the German Aerospace Centre DLR and the LMU University in Munich, told Space.com. "The sphere is just the front end," Eisenberg said. "All the voice recognition and artificial intelligence happens on Earth at an IBM data centre in Frankfurt, Germany. The signal from CIMON has to travel through satellites and ground stations to the data centre and back. We focused on improving the robustness of this connection to prevent disruptions." CIMON relies on IBM's Watson speech recognition and synthesis software to converse with astronauts and respond to their commands. The first generation robot flew to the space station with Alexander Gerst in 2018. That robot later returned to Earth and is now touring German museums. The current robot, CIMON-2, is a second generation. Unlike its predecessor, it is more attuned to the astronauts' emotional states (thanks to the Watson Tone Analyzer). It also has a shorter reaction time. Airbus and DLR have signed a contract with ESA for CIMON-2 to work with four humans on the orbital outpost in the upcoming years. During those four consecutive missions, engineers will first test CIMON's new software and then move on to allowing the sphere to participate in more complex experiments. During these new missions CIMON will, for the first time, guide and document complete scientific procedures, Airbus said in a statement. "Most of the activities that astronauts perform are covered by step by step procedures," Eisenberg said. "Normally, they have to use clip boards to follow these steps. But CIMON can free their hands by floating close by, listening to the commands and reading out the procedures, showing videos, pictures and clarifications on its screen." The robot can also look up additional information and document the experiments by taking videos and pictures. The scientists will gather feedback from the astronauts to see how helpful the sphere really was and identify improvements for CIMON's future incarnations.

"Ask for a roast beef sandwich at an Arby's drive-thru east of Los Angeles and you may be talking to Tori — an artificially intelligent voice assistant that will take your order and send it to the line cooks," reports the Associated Press. They're arguing that the pandemic "didn't just threaten Americans' health when it slammed the U.S. in 2020 — it may also have posed a long-term threat to many of their jobs." Faced with worker shortages and higher labor costs, companies are starting to automate service sector jobs that economists once considered safe, assuming that machines couldn't easily provide the human contact they believed customers would demand. Past experience suggests that such automation waves eventually create more jobs than they destroy, but that they also disproportionately wipe out less skilled jobs that many low-income workers depend on. Resulting growing pains for the U.S. economy could be severe... Ideally, automation can redeploy workers into better and more interesting work, so long as they can get the appropriate technical training, says Johannes Moenius, an economist at the University of Redlands. But although that's happening now, it's not moving quickly enough, he says. Worse, an entire class of service jobs created when manufacturing began to deploy more automation may now be at risk. "The robots escaped the manufacturing sector and went into the much larger service sector," he says. "I regarded contact jobs as safe. I was completely taken by surprise." Improvements in robot technology allow machines to do many tasks that previously required people — tossing pizza dough, transporting hospital linens, inspecting gauges, sorting goods. The pandemic accelerated their adoption. Robots, after all, can't get sick or spread disease. Nor do they request time off to handle unexpected childcare emergencies. Economists at the International Monetary Fund found that past pandemics had encouraged firms to invest in machines in ways that could boost productivity — but also kill low-skill jobs. "Our results suggest that the concerns about the rise of the robots amid the COVID-19 pandemic seem justified," they wrote in a January paper... Employers seem eager to bring on the machines. A survey last year by the nonprofit World Economic Forum found that 43% of companies planned to reduce their workforce as a result of new technology. Since the second quarter of 2020, business investment in equipment has grown 26%, more than twice as fast as the overall economy.

An anonymous reader quotes a report from Ars Technica, written by Tim De Chant: GM announced last Friday that it was recalling every Chevrolet Bolt it had ever made, including the new electric utility vehicle model that debuted this year. After a string of fires affected Bolt models, the company traced the problem to two simultaneously occurring defects in the cars' LG Chem-made batteries. The automaker initially discovered the problem in batteries from one of LG's Korean plants, and it recalled cars with those cells last November. But then more Bolts caught fire, and other LG plants were ensnared in the investigation, spurring two expansions of the recall. The problem, GM said, has been traced to a torn anode tab and a folded separator. That's all GM has said so far. It hasn't said how widespread the defects are, nor has it said how, exactly, the fires started. But in what little information has been released, and in the timing of GM's recalls, there are clues. To decipher them, Ars spoke with Greg Less, technical director of the University of Michigan's Battery Lab. "What we're looking at is a perfect storm," Less said. The Bolt's battery packs are made up of pouch-type cells, which are essentially layers of cathodes, anodes, and separators that are flooded with liquid electrolyte and encased in a flexible polymer pouch. The torn anode tab, he said, would create a projection in what should be an otherwise flat battery. The projection brings the anode closer to the cathode. "And that would probably be OK if the separator was where it was supposed to be," he said. But in problematic Bolt batteries, the separator wasn't where it was supposed to be. Separators are placed between the anode and cathode to prevent the two electrodes from touching. A torn tab wouldn't necessarily be an issue on its own because the separator would prevent any projection from bridging the anode-cathode gap. In cells with a folded separator, though, the gap would be missing from at least part of the battery. If the anode bridges the gap, Less said, "you have a short, and it's all downhill from there." "It wouldn't surprise me if both defects are caused by the same thing," he added. "I would imagine that the separator must be folded at the edge near where the anode tab is at. What I'm guessing is that at some point during the handling of the cell, before it's fully packaged, some part of the robot machine is catching. The tab is catching, the separator is catching -- something is catching very infrequently so that it hasn't been noticed, and it's causing this damage."

At Tesla's AI Day event, Elon Musk revealed a humanoid robot called Tesla Bot that utilizes the same artificial intelligence that powers the company's autonomous vehicles. CNET reports: Musk revealed few details about the Slenderman-looking Tesla Bot outside of a few PowerPoint slides but reiterated some of his beliefs about human labor. "They can use all of the same tools that we use in the car," Musk noted, suggesting the robot could be told to "go to the store and get ... the following groceries." A prototype would likely be ready next year, Musk said. "It's intended to be friendly," Musk joked, "and navigate through a world built for humans."

An anonymous reader quotes a report from PCMag: Boston Dynamics taught its robots to dance last year, now one of them can complete a parkour course. The robot company, which is owned by Hyundai, has released two new videos today. The first shows off how well the Atlas robot can perform parkour, while the second video takes us behind the scenes and explains how Atlas works. It's actually the first time Atlas has managed to complete the complex obstacle course flawlessly, and Boston wants to celebrate that. After the dancing video last year, we all expect Boston's robots to do amazing things now, and the parkour video doesn't disappoint. But what it doesn't show is all the hard work, missteps, and problems that need fixing in order to make these demonstrations possible. That's what the second video reveals, and it's the first time I've seen these robots breakdown and leak fluids. There's a hardware team, a software team, technicians, and operations staff required to make this whole operation work. Each Atlas requires three onboard computers in order to process the sensor data and run the algorithms allowing this 5ft, 190lbs robot to move with 28-degrees of freedom without falling over (very often). And even though we're asking these robots to do the same actions as humans, it's a very different challenge.

A recovery mission off Vietnam's coast showed how advances in technology have given new reach to the Pentagon's search for American war dead. From a report: On a July morning in 1967, two American B-52 bombers collided over the South China Sea as they approached a target in what was then South Vietnam. Seven crew members escaped, but rescue units from the Air Force, Navy and Coast Guard were unable to find six other men, including a navigator from New York, Maj. Paul A. Avolese. It wasn't until last year that scientists scanning the seafloor found one of the B-52s and recovered Major Avolese's remains. "It was very humbling to be diving a site that turned out as hallowed ground, and realizing that maybe we were in a position to help bring closure back to families that had been missing this lost aviator," said Eric J. Terrill, one of two divers who descended to the wreck. Scientists say the recovery highlights a shift in the Pentagon's ability to search for personnel still missing from the Vietnam War. For decades, such efforts have mainly focused on land in former conflict zones. But in this case, American investigators looked at an underwater site near Vietnam's long coastline, using high-tech robots. Their use of that technology is part of a larger trend. Robotic underwater and surface vehicles are "rapidly becoming indispensable tools for ocean science and exploration," said Rear Adm. Nancy Hann, who manages a fleet of nine aircraft and 16 research and survey vessels for the National Oceanic and Atmospheric Administration. "They have proven to be a force multiplier when it comes to mapping the seafloor, locating and surveying wrecks and other sunken objects, and collecting data in places not easily accessed by ships and other vehicles," Admiral Hann said. One reason for the new focus on Vietnam's undersea crash sites is that many land-based leads have been exhausted, said Andrew Pietruszka, the lead archaeologist for Project Recover, a nonprofit organization. The group worked on the recent recovery mission with the Defense POW/MIA Accounting Agency, or D.P.A.A., the arm of the Pentagon tasked with finding and returning fallen military personnel. "Over time, a lot of the really good land cases and sites they've already done, they've already processed them," said Mr. Pietruszka, a former forensic archaeologist for D.P.A.A. who now works for the Scripps Institution of Oceanography at the University of California, San Diego. "Now the majority of sites that haven't been looked at are falling in that underwater realm," he added.
