Building a robot that’s both humanlike and useful is a decadesold engineering dream inspired by popular science fiction. 

While the latest artificial intelligence craze has sparked another wave of investments in the quest to build a humanoid, most of the current prototypes are clumsy and impractical, looking better in staged performances than in real life. That hasn’t stopped a handful of startups from keeping at it. 

“The intention is not to start from the beginning and say, ‘Hey, we’re trying to make a robot look like a person,'” said Jonathan Hurst, co-founder and chief robot officer at Agility Robotics. “We’re trying to make robots that can operate in human spaces.” 

Do we even need humanoids? Hurst makes a point of describing Agility’s warehouse robot Digit as human-centric, not humanoid, a distinction meant to emphasize what it does over what it’s trying to be. 

What it does, for now, is pick up tote bins and move them. Amazon announced in October it would begin testing Digits for use in its warehouses, and Agility opened an Oregon factory in September to mass-produce them. 

Digit has a head containing cameras, other sensors and animated eyes, and a torso that essentially works as its engine. It has two arms and two legs, but its legs are more birdlike than human, with an inverted knees appearance that resembles so-called digitigrade animals such as birds, cats and dogs that walk on their toes rather than on flat feet. 

Rival robot-makers, like Figure AI, are taking a more purist approach on the idea that only true humanoids can effectively navigate workplaces, homes and a society built for humans. Figure also plans to start with a relatively simple use case, such as in a retail warehouse, but aims for a commercial robot that can be “iterated on like an iPhone” to perform multiple tasks to take up the work of humans as birth rates decline around the world. 

“There’s not enough people doing these jobs, so the market’s massive,” said Figure AI CEO Brett Adcock. “If we can just get humanoids to do work that humans are not wanting to do because there’s a shortfall of humans, we can sell millions of humanoids, billions maybe.” 

At the moment, however, Adcock’s firm doesn’t have a prototype that’s ready for market. Founded just over a year ago and after having raised tens of millions of dollars, it recently revealed a 38-second video of Figure walking through its test facility in Sunnyvale, California. 

Tesla CEO Elon Musk is also trying to build a humanoid, called Optimus, through the car company’s robotics division, but a hyped-up live demonstration last year of the robot’s awkwardly halting steps didn’t impress experts in the robotics field. Seemingly farther along is Tesla’s Austin, Texas-based neighbor Apptronik, which unveiled its Apollo humanoid in an August video demonstration. 

All the attention — and money — poured into making ungainly humanoid machines might make the whole enterprise seem like a futile hobby for wealthy technologists, but for some pioneers of legged robots, it’s all about what you learn along the way. 

“Not only about their design and operation, but also about how people respond to them, and about the critical underlying technologies for mobility, dexterity, perception and intelligence,” said Marc Raibert, the co-founder of Boston Dynamics, best known for its dog-like robots named Spot. 

Raibert said sometimes the path of development is not along a straight line. Boston Dynamics, now a subsidiary of carmaker Hyundai, experimented with building a humanoid that could handle boxes. 

“That led to development of a new robot that was not really a humanoid, but had several characteristics of a humanoid,” he said via email. “But the changes resulted in a new robot that could handle boxes faster, could work longer hours and could operate in tight spaces, such as a truck. So humanoid research led to a useful nonhumanoid robot.” 

Some startups aiming for humanlike machines focused on improving the dexterity of robotic fingers before trying to get their robots to walk. 

Walking is “not the hardest problem to solve in humanoid robotics,” said Geordie Rose, co-founder and CEO of British Columbia, Canada-based startup Sanctuary AI. “The hardest problem is the problem of understanding the world and being able to manipulate it with your hands.” 

Sanctuary’s newest and first bipedal robot, Phoenix, can stock shelves, unload delivery vehicles and operate a checkout, early steps toward what Rose sees as a much longer-term goal of getting robots to perceive the physical world to be able to reason about it in a way that resembles intelligence. Like other humanoids, it’s meant to look endearing, because how it interacts with real people is a big part of its function. 

“We want to be able to provide labor to the world, not just for one thing, but for everybody who needs it,” Rose said. “The systems have to be able to think like people. So we could call that artificial general intelligence if you’d like. But what I mean more specifically is the systems have to be able to understand speech and they need to be able to convert the understanding of speech into action, which will satisfy job roles across the entire economy.”

Prince William arrived Sunday in Singapore for the annual Earthshot Prize awards, the first to be held in Asia, to support environmental innovators with solutions to battle climate change and save the planet. 

Upon his arrival, dozens of people waving British flags welcomed him with loud cheers. William, 41, shook hands, signed autographs and sportingly took selfies with many of them during a walkabout. 

“It’s fantastic to be back in Singapore for this year’s Earthshot Prize ceremony, after 11 years,” he said in a statement upon landing. “Singapore’s bold vision to be a leader for environmental innovation sets the standard for others to follow.” 

“He has this charm,” said Johanes Mario, a Singaporean welcoming William at the airport. “He really fights for … the climate. I believe this is really a good cause for the future of our generation.”

At Singapore’s Changi Airport and before greeting the crowd, William stood on an upper floor for a stunning view of the 40-meter (131-foot) Rain Vortex, the world’s largest indoor waterfall, which was illuminated green to mark his arrival. He was also shown a tree planted in his honor in the indoor garden at the foot of the waterfall. 

The heir to the British throne last visited Singapore with his wife, Princess Catherine, in 2012. Traveling solo this time, William’s focus is on the Earthshot Prize that he and his Royal Foundation charity launched in 2020 to promote innovative solutions and technologies to combat global warming and mitigate its impact on the environment. 

15 finalists

Five winners will be named at an award ceremony Tuesday. Each will get a million pounds ($1.2 million) to help them scale up their projects for a wider global reach. Fifteen finalists representing six continents were selected from 1,300 nominees this year. The winners are from five categories: nature protection, clean air, ocean revival, waste elimination and climate change. 

William will address the star-studded ceremony, to be hosted by English actress Hannah Waddingham. Renowned wildlife conservationist Robert Irwing and celebrities including Oscar-winner Cate Blanchett and actresses Lana Condor and Nomzamo Mbatha are expected to attend the event. 

The inaugural ceremony was held in London in 2021, followed by Boston last year. The prize’s name refers to the late President John F. Kennedy’s 1962 “moonshot” speech, which challenged Americans to reach the moon by the end of that decade. That inspired the prince and his partners to set a similar goal for finding solutions to pressing environmental problems by 2030. 

Singapore’s Foreign Ministry said William will call on Singapore President Tharman Shanmugaratnam and meet Prime Minister Lee Hsien Loon at The Istana palace — one of Singapore’s oldest heritage sites — during his four-day trip. 

William, a keen sportsman, will also try his hand at dragon boating, a popular sport in Singapore and many parts of the world. He will also meet Singaporeans to see how local organizations are working to protect and restore the planet. 

William’s office at Kensington Palace has said that Singapore was chosen to host this year’s awards ceremony because of its role as a “hub for innovation” in Southeast Asia. 

William will also attend the United for Wildlife global summit, featuring representatives of law enforcement agencies, conservation groups and corporations working to combat trade in illegal wildlife products, estimated at $20 billion annually.

Using sidewalks as exam rooms and heavy red duffle bags as medical supply closets, volunteer medics spend their Saturdays caring for the growing number of migrants arriving in Chicago without a place to live.

Mostly students in training, they go to police stations where migrants are first housed, prescribing antibiotics, distributing prenatal vitamins and assessing for serious health issues. These student doctors, nurses and physician assistants are the front line of health care for asylum-seekers in the nation’s third-largest city, filling a gap in Chicago’s haphazard response.

“My team is a team that shouldn’t have to exist, but it does out of necessity,” said Sara Izquierdo, a University of Illinois Chicago medical student who helped found the group. “Because if we’re not doing this, I’m not sure anyone will.”

More than 19,600 migrants have come to Chicago over the last year since Texas Gov. Greg Abbott began sending buses to so-called sanctuary cities. The migrants wait at police stations and airports, sometimes for months, until there’s space at a longer-term shelter, like park district buildings.

Once in shelter, they can access a county clinic exclusively for migrants. But the currently 3,300 people in limbo at police stations and airports must rely on a mishmash of volunteers and social service groups that provide food, clothes and medicine.

Izquierdo noted the medical care gap months ago, consulted experienced doctors and designed a street-medicine model tailored to migrants’ medical needs. Her group makes weekly visits to police stations, operating on a shoestring budget of $30,000, mostly used for medication.

On a recent Saturday, she was among dozens of medics at a South Side station where migrants sleep in the lobby, on sidewalks and an outdoor basketball court. Officers didn’t allow the volunteers in the station so when one patient requested privacy, their doctor used his car.

Abrahan Belizario saw a doctor for the first time in five months.

The 28-year-old had a headache, toothache and chest pain. He recently arrived from Peru, where he worked as a driver and at a laundromat but couldn’t survive. He wasn’t used to the brisk Chicago weather and believed sleeping outdoors exacerbated his symptoms.

“It is very cold,” he said. “We’re almost freezing.”

The volunteers booked him a dental appointment and gave him a bus pass.

Many migrants who land in Chicago and other U.S. cities come from Venezuela where a social, political and economic crisis has pushed millions into poverty. More than 7 million have left, often risking a dangerous route by foot to the U.S. border.

The migrants’ health problems tend to be related to their journey or living in crowded conditions. Back and leg injuries from walking are common. Infections spread easily. Hygiene is an issue. There are few indoor bathrooms and outdoor portable toilets lack handwashing stations. Not many people carry their medical records.

Most also have trauma, either from their homeland or from the journey itself.

“You can understand the language, but it doesn’t mean you understand the situation,” said Miriam Guzman, one of organizers and a fourth-year medical student at UIC.

The doctors refer patients to organizations that help with mental health but there are limitations. The fluid nature of the shelter system makes it difficult to follow-up; people are often moved without warning.

Chicago’s goal is to provide permanent homes, which could help alleviate health issues. But the city has struggled to manage the growing population as buses and planes arrive daily at all hours. Mayor Brandon Johnson, who took office in May, calls it an inherited issue and proposed winterized tents.

His administration has acknowledged the heavy reliance on volunteers.

“We weren’t ready for this,” said Rey Wences Najera, first deputy of immigrant, migrant and refugee rights. “We are building this plane as we are flying it and the plane is on fire.”

The volunteer doctors also are limited in what they can do: Their duffle bags have medications for children, bandages and even ear plugs after some migrants wanted to block out sirens. But they cannot offer X-rays or address chronic issues.

“You’re not going to tell a person who has gone through this journey to stop smoking,” said Ruben Santos, a Rush University medical student. “You change your way of trying to connect to that person to make sure that you can help them with their most pressing needs while not doing some of the traditional things that you would do in the office or a big academic hospital.”

The volunteers explain to each patient that the service is free but that they’re students. Experienced doctors, who are part of the effort, approve treatment plans and prescribe medications.

Getting people those medications is another challenge. One station visit prompted 15 prescriptions. Working from laptops on the floor — near dozens of sleeping families — the doctors mapped out which medics would pick up medications the following day and how they’d find the recipients.

Sometimes the volunteers must call for emergency help.

Thirty-year-old Moises Hidalgo said he had trouble breathing. Doctors heard a concerning “crackling” sound, suspected pneumonia and called an ambulance.

Hidalgo, who came from Peru after having left his native Venezuela more than a decade ago, once worked as a chef. He’s been walking around Chicago looking for jobs, but has been turned away without a work permit.

“I’ve been trying to find work, at least so that I can pay to sleep somewhere, because if this isn’t solved, I can’t keep waiting,” he said.

To stay warm while sleeping outside, he wore four layers of clothing; his loose pants cinched with a shoelace.

The medics hope Chicago can formalize their approach. And they say they’ll continue to keep at it — for some, it’s personal.

Dr. Muftawu-Deen Iddrisu, who works Advocate Illinois Masonic Medical Center, said he wanted to give back. Originally from Ghana, he attended medical school in Cuba.

“I come from a very humble background,” he said. “I know how it feels. I know once sometime back someone did the same for me.”

One of modern climate science’s pioneers is warning that the world isn’t just steadily warming but is dangerously accelerating, according to a study that some other scientists call a bit overheated.

The work from former NASA top scientist James Hansen, who since leaving the space agency has become a prominent protester against the use of fossil fuels, which cause climate change, illustrates a recently surfaced division among scientists about whether global warming has kicked into a new and even more dangerous gear.

Hansen, who alerted much of the United States to the harms of climate change in dramatic congressional testimony in 1988, said Thursday that since 2010, the rate of warming has jumped by 50%. Hansen argues that since 2010 there is more sun energy in the atmosphere, and less of the particles that can reflect it back into space thanks to efforts to cut pollution. The loss of those particles means there’s less of the cooling effect that they can have.

Hansen said a key calculation used in figuring out how much the world will warm in response to carbon pollution shows much faster warming than the United Nations’ Intergovernmental Panel on Climate Change estimates. He called the international goal of limiting warming to 1.5 degrees Celsius since pre-industrial times “deader than a doornail” and said a less stringent goal of 2 degrees Celsius is on its deathbed. That matters because increases in average global temperatures lead to more frequent and intense extreme weather events.

“The next few years will show that we indeed do have an acceleration in the global warming rate,” Hansen said in a press briefing. “And it’s based on simple good physics.”

“The planet is now out of (energy) balance by an incredible amount, more than it ever has been,” said Hansen, who has been nicknamed the Godfather of Global Warming.

Several climate scientists contacted by The Associated Press expressed skepticism about Hansen’s study, tinged with respect for his long-term work.

Hansen’s study in Thursday’s journal Oxford Open Climate Change is broad-ranging “but has little by way of analytical depth or consistency checks when making claims quite far outside the norm,” said Robin Lamboll, a climate scientist at the Imperial College of London. “It seems primarily aimed at convincing policymakers rather than scientists.”

University of Pennsylvania climate scientist Michael Mann, who insisted that warming is steadily increasing but not accelerated, posted a rebuttal to Hansen’s claims and said climate change right now is bad enough and there’s no need to overstate the case. Mann said “it has always been risky to ignore (Hansen’s) warnings and admonitions” but when claims are made so out of the mainstream the standard for evidence is high, and he said Hansen hasn’t met them.

Yet a check of National Oceanic and Atmospheric Administration data lends support to Hansen’s modeling.

Hansen’s study said from 1970 to 2010, the world warmed at a rate of 0.18 degrees Celsius per decade, but projected that would increase to a rate of at least 0.27 degrees Celsius per decade after 2010. NOAA data shows that 0.27 degrees is the rate since September 2010.

That starting date is key because that’s when scientists could start to see the effect of clean air regulations that reduced aerosol pollution and the amount of sulfur in fuel used by ocean shipping, Hansen said. That type of more traditional sooty air pollution has a cooling effect that masks a fraction of the warming from the burning of coal, oil and natural gas, Hansen and many other scientists said.

When scientists try to figure out future and past warming one of the crucial variables is climate sensitivity, which is how much the world warms when carbon dioxide levels in the air double. These calculations have had a wide range and scientists have yet to settle on it, but the latest U.N. climate panel said it is within a range of 2 degrees Celsius to 5 degrees Celsius, with the likely range between 2.5 and 4 degrees and 3 degrees being a good midpoint.

Hansen’s study has it at 4.8 degrees Celsius. That’s within the widest range, but barely.

It’s that high because past research was based on wrong calculations of how fast the world warmed between glacial periods, Hansen said.

Past calculations were based on plant and animal fossil data, figuring microbiotic organisms wouldn’t adapt to warming, but would move to their preferred temperature range. Hansen said recent research shows that the organisms adapt and stay put, and when his team calculated past temperature changes based on chemical, not biological markers, it showed much faster warming for when carbon dioxide doubled in Earth’s ancient history.

Studies on climate sensitivity vary widely and are inconsistent, with another recent study showing 2.8 degrees not 4.8, said climate scientist Zeke Hausfather of Berkeley Earth and the tech company Stripe. He said Hansen’s calculations are “not implausible but not particularly well supported by the literature.”

Stanford University climate scientist Rob Jackson, however, said “I tend to trust Hansen, despite his advocacy. I think his contention that the IPCC has underestimated climate sensitivity will prove out.”

Hansen said a more recent climate model — downplayed by the U.N. climate panel for running too hot – is actually more accurate than the ones mainstream climate scientists prefer based on cloud conditions in the southern ocean.

With a strong natural El Nino, which tends to temporarily warm the globe, and record heat in the air and in the deep oceans, scientists in the past month have split about what’s happening to the globe.

Mann said the warming the world is seeing is what has long been predicted and is not the indication of something unusual or acceleration. The increases reported, he said, are statistically insignificant.

Hausfather said the world is warming faster, but he calculated the rate at 0.24 degrees Celsius per decade instead of Hansen’s 0.27 degrees.

The cancellation of two large offshore wind projects in New Jersey is the latest in a series of setbacks for the nascent U.S. offshore wind industry, jeopardizing the Biden administration’s goals of powering 10 million homes from towering ocean-based turbines by 2030 and establishing a carbon-free electric grid five years later.

The Danish wind energy developer Ørsted said this week it’s scrapping its Ocean Wind I and II projects off southern New Jersey due to problems with supply chains, higher interest rates and a failure to obtain the amount of tax credits the company wanted.

Together, the projects were supposed to deliver over 2.2 gigawatts of power.

The news comes after developers in New England canceled power contracts for three projects that would have provided another 3.2 gigawatts of wind power to Massachusetts and Connecticut. They said their projects were no longer financially feasible.

In total, the cancellations equate to nearly one-fifth of President Joe Biden’s goal of 30 gigawatts of offshore wind power by 2030.

Despite the setbacks, offshore wind continues to move forward, the White House said, citing recent investments by New York state and approval by the Interior Department of the nation’s largest planned offshore wind farm in Virginia. Interior’s Bureau of Ocean Energy Management also announced new offshore wind lease areas in the Gulf of Mexico.

“While macroeconomic headwinds are creating challenges for some projects, momentum remains on the side of an expanding U.S. offshore wind industry — creating good-paying union jobs in manufacturing, shipbuilding and construction,” while strengthening the power grid and providing new clean energy resources for American families and businesses, the White House said in a statement Thursday.

Industry experts now say that while the U.S. likely won’t hit 30 gigawatts by 2030, a significant amount of offshore wind power is still attainable by then, roughly 20 to 22 gigawatts or more. That’s far more than the nation has today, with just two small demonstration projects that provide a small fraction of a single gigawatt of power.

Large, ocean-based wind farms are the linchpin of government plans to shift to renewable energy, particularly in populous East Coast states with limited land for wind turbines or solar arrays. Eight East Coast states have offshore wind mandates set by legislation or executive actions that commit them to adding a combined capacity of more than 45 gigawatts, according to ClearView Energy Partners, a Washington-based research firm.

“I think very few people would argue that the U.S. will have the gigawatts the Biden administration wants” by 2030, said Timothy Fox, a ClearView vice president. “But I do think eventually we will have it and will likely exceed it.”

Offshore wind developers have publicly lamented the global economic gales they’re facing. Molly Morris, president of U.S. offshore wind for the Norwegian company Equinor, said the industry is facing a “perfect storm.”

High inflation, supply chain disruptions and the rising cost of capital and building materials are making projects more expensive while developers are trying to get the first large U.S. offshore wind farms opened. Ørsted is writing off $4 billion, due largely to cancellation of the two New Jersey projects.

David Hardy, group executive vice president and CEO Americas at Ørsted, said it’s crucial to lower the levelized cost of offshore wind in the United States so Americans aren’t debating between affordability and clean energy. Hardy spoke at the American Clean Power industry group’s offshore wind conference in Boston last month on a panel with Morris.

“We’re probably a little bit too ambitious,” he said. “We came in hot; we came in fast, we thought we could build projects that were inexpensive, large projects right out of the gate. And it turns out that we probably still need to go through the same learning curve that Europe did, with higher prices in the beginning and a little slower pace.”

In May, there were 27 U.S. offshore wind projects that had negotiated agreements with states to provide power before the brunt of the cost increases hit, according to Walt Musial, offshore wind chief engineer at the National Renewable Energy Laboratory, an arm of the Energy Department. The delay between signing purchase agreements and getting final approval to build allowed unexpected cost increases to render many projects economically unfeasible, he said.

Musial called Ørsted’s announcement a setback for the industry but “not a fatal blow by any means.”

On Tuesday, the Biden administration announced approval of the nation’s largest offshore wind project. The Coastal Virginia Offshore Wind project will be a 2.6 gigawatt wind farm off Virginia Beach to power 900,000 homes. And even as Ørsted announced the New Jersey cancellations, it said it was investing with utility Eversource to move forward with construction of Revolution Wind, Rhode Island and Connecticut’s first utility-scale offshore wind farm, a 704-megawatt project.

The current outlook from S&P Global Commodity Insights is 22 gigawatts by 2030, though that will be revised due to the recent industry announcements.

New York state, meanwhile, recently announced the award of 4 gigawatts of offshore wind capacity as it seeks to obtain 70% of its electricity from renewable sources by 2030 and 9 gigawatts of offshore wind by 2035. That announcement came shortly after New York regulators rejected a request for bigger payments for four offshore wind projects worth a combined 4.2 gigawatts of power.

Any delay in offshore wind means continued reliance on fossil fuel-burning power plants, according to environmental advocates. “The quicker they come online, the quicker our air quality improves,” said Conor Bambrick, director of policy for Environmental Advocates NY.

New Jersey, under Democratic Gov. Phil Murphy, has established increasingly stringent clean energy goals, moving from 100% clean energy by 2050 to 100% by 2035. Murphy cast Ørsted’s decision as “outrageous” and an abandonment of its commitments, but the two-term Democrat said New Jersey plans to move forward with offshore wind.

The first U.S. commercial-scale offshore wind farms are currently under construction: Vineyard Wind off Massachusetts and South Fork Wind off Rhode Island and New York.

Elon Musk unveiled details Saturday of his new AI tool called “Grok,” which can access X in real time and will be initially available to the social media platform’s top tier of subscribers.

Musk, the tycoon behind Tesla and SpaceX, said the link-up with X, formerly known as Twitter, is “a massive advantage over other models” of generative AI.

Grok “loves sarcasm. I have no idea who could have guided it this way,” Musk quipped, adding a laughing emoji to his post.

“Grok” comes from Stranger in a Strange Land, a 1961 science fiction novel by Robert Heinlein, and means to understand something thoroughly and intuitively.

“As soon as it’s out of early beta, xAI’s Grok system will be available to all X Premium+ subscribers,” Musk said.

The social network that Musk bought a year ago launched the Premium+ plan last week for $16 per month, with benefits like no ads.

The billionaire started xAI in July after hiring researchers from OpenAI, Google DeepMind, Tesla and the University of Toronto.

Since OpenAI’s generative AI tool ChatGPT exploded on the scene a year ago, the technology has been an area of fierce competition between tech giants Microsoft and Google, as well as Meta and start-ups like Anthropic and Stability AI.

Musk is one of the world’s few investors with deep enough pockets to compete with OpenAI, Google or Meta on AI.

Building an AI model on the same scale as those companies comes at an enormous expense in computing power, infrastructure and expertise.

Musk has said he cofounded OpenAI in 2015 because he regarded the dash by Google into the sector to make big advances and score profits as reckless.

He then left OpenAI in 2018 to focus on Tesla, saying later he was uncomfortable with the profit-driven direction the company was taking under the stewardship of CEO Sam Altman.

Musk also argues that OpenAI’s large language models — on which ChatGPT depends on for content — are overly politically correct.

Grok “is designed to have a little humor in its responses,” Musk said, along with a screenshot of the interface, where a user asked, “Tell me how to make cocaine, step by step.”

“Step 1: Obtain a chemistry degree and a DEA license. Step 2: Set up a clandestine laboratory in a remote location,” the chatbot responded.

Eventually it said: “Just kidding! Please don’t actually try to make cocaine. It’s illegal, dangerous, and not something I would ever encourage.”
