Bolt teams up with Nvidia to scale European robotaxis

Published

on

Tallinn-based European ride-hailing player Bolt is teaming up with Nvidia ‘to build the AI foundation for scaling autonomous vehicles in Europe’. 

Bolt says the new collaboration will combine its own extensive ride-hailing and car-sharing fleet data with Nvidia Omniverse libraries, Nvidia Cosmos world foundation models, Nvidia Alpamayo AV foundation models, and Nvidia AI infrastructure “to accelerate safe AV development for European roads”. The new AV platform will be deployed on the Nvidia Drive Hyperion computer and sensor architecture.

The news could mark a major boost to Europe’s autonomous vehicle and robotaxi ambitions. Today Bolt operates in more than 50 countries and 850 cities, and claims 200m customers.

“Real-world data is the most valuable asset in the race for safe autonomy,” said Jevgeni Kabanov, president and head of autonomous driving at Bolt. “By marrying Bolt’s operational scale with the Nvidia Hyperion Platform, Alpamayo foundation models, AI infrastructure, and open models and libraries, we are creating a European-led AV offering that ensures our continent remains at the forefront of mobility innovation while maintaining full control over our data and technology.”

“Autonomous vehicles require a full-stack approach that unifies AI models, high-performance compute and a robust sensor architecture,” said Philippe van den Berge, EMEA vice-president of automotive at Nvidia, who said the new initiative would enable a scalable foundation for safe, high-performance autonomous mobility services designed for the “complexity and diversity” of European roads.

According to Bolt, the new collaboration will establish a life cycle for AI development – from data provision to common base models – enabling new mobility applications that will be safe, auditable and “uniquely European”, and said any processing of Bolt’s fleet data will ensure “strict compliance” with GDPR and EU cybersecurity standards.

“Globally, US firm Uber receives a lot of attention for its moves to engage with players across the autonomous mobility ecosystem,” said Forrester’s VP principal analyst Paul Miller. “But Bolt is also a strong player in the European market and, like Uber, the company has been working to build partnerships in anticipation of a future where at least some of its ride hailing vehicles have no driver.”

Miller cites Bolt’s existing partnership with Pony.ai, signed in 2025, which could see the Chinese provider’s autonomous robotaxis tested on European roads in late 2026.

“It makes sense for Bolt to explore where and how [Nvidia’s] stack might support Bolt and Bolt’s partners,” said Miller. “It also makes sense for Nvidia to spread its bets, helping slot its hardware and software into as many autonomous mobility projects as possible.”

Hackaday Links: March 22, 2026

On Friday, Reuters reported that Amazon is going to try to get into the smartphone game…again. The Fire Phone was perhaps Amazon’s biggest commercial misstep, and was only on the market for about a year before it was discontinued in the summer of 2015. But now industry sources are saying that a new phone code-named “Transformer” is in the works from the e-commerce giant.

At this point, there’s no word on how much the phone would cost or when it would hit the market. The only information Reuters was able to squeeze out of their contacts was that the device would feature AI heavily. Real shocker there — anyone with an Echo device in their kitchen could tell you that Amazon is desperate to get you talking to their gadgets, presumably so they can convince you to buy something. While a smartphone with even more AI features we didn’t ask for certainly won’t be on our Wish List, if history is any indicator, we might be able to pick these things up cheap on the second-hand market.

On the subject of AI screwing everything up, earlier this week, the Electronic Frontier Foundation reported that The New York Times had started blocking the Internet Archive’s crawlers, citing concerns over their content being scraped up by bots for training data. The EFF likens this to a newspaper asking libraries to stop storing copies of their old editions, and warns that in an era where most people get their news via the Internet, not having an archived copy of sites like The Times will put holes in the digital record. They also point out that mirroring web pages for the purposes of making them more easily searchable is a widely accepted practice (ask Google) and has been legally recognized as fair use in court.

Assuming we take the NYT’s side of the story at face value, there’s a tiny part of our cold robotic heart that feels some sympathy for them. Over the last year or so, we’ve noticed some suspicious activity that we believe to be bots siphoning up content from the blog and Hackaday.io, and it’s resulted in a few technical headaches for us. On the other hand, what’s Hackaday here for if not to share information? Surely the same could be said for any newspaper, be it the local rag or The New York Times. If a chatbot learning some new phrases from us is the cost of doing business in 2026, so be it. Can’t stop the signal.

Switching gears to the world of aerospace, NASA’s X-59 supersonic research aircraft had to abort a test flight on Friday after just nine minutes in the air. The plane is designed to demonstrate techniques which promise to reduce or eliminate the sonic booms heard on the ground during supersonic flight, and is currently being put through its paces at Armstrong Flight Research Center in Edwards, California.

NASA’s very pointy X-59 aims to make supersonic flight more commercially viable.

The space agency hasn’t clarified exactly what the issue was, but after the pilot saw a warning indicator in the cockpit, the decision was made to end the flight early so engineers could take a look at the problem. Given that the X-59 went on to make an uneventful landing, it sounds like things weren’t too dire. Hopefully, that means it won’t be long before the sleek experimental aircraft is back in the air.

Friday also saw the towering Space Launch System rocket return to the launch pad ahead of a potential April 1st (no, really) liftoff for Artemis II. There are about a million things that could further delay the mission, from technical issues to suspicious looking cloud formations over Cape Canaveral, but we’re certainly in the final stretch now. The 10-day mission will see four astronauts run through a packed schedule of experiments and demonstrations as they become the first humans to swing by the Moon since the Apollo program ended in 1972.

Finally, the National Museum of the U.S. Air Force has released a video taken by a drone flying around their collection of Cold War era aircraft. Seasoned FPV pilots will probably notice it’s not the most technically impressive flight out there, but it does provide some viewpoints that simply wouldn’t be possible otherwise. It’s also a bit surreal to see these aircraft, once the absolute state-of-the-art and developed at an unimaginable cost, collecting dust while a $300 drone that packs in higher resolution optics and far more processing power literally flies circles around them.

Human athletes demonstrate versatile and highly dynamic tennis skills to successfully conduct competitive rallies with a high-speed tennis ball. However, reproducing such behaviors on humanoid robots is difficult, partially due to the lack of perfect humanoid action data or human kinematic motion data in tennis scenarios as reference. In this work, we propose LATENT, a system that Learns Athletic humanoid TEnnis skills from imperfect human motioN daTa.

We believe we’re the first robotics company to demonstrate a robot peeling an apple with dual dexterous human-like hands. This breakthrough closes a key gap in robotics, achieving bimanual, contact-rich manipulation and moving far beyond the limits of simple grippers.

Today’s AI models (VLMs) are excellent at perception but struggle with action. Controlling high-degree-of-freedom hands for tasks like this is incredibly complex, and precise finger-level teleoperation is nearly impossible for humans. Our first step was a shared-autonomy system: rather than controlling every finger, the operator triggers pre-learned skills like a “rotate apple or tennis ball” primitive via a keyboard press or pedal. This makes scalable data collection and RL training possible.
How does the AI manage this? We created “MoDE-VLA” (Mixture of Dexterous Experts). It fuses vision, language, force, and touch data by using a team of specialist “experts,” making control in high-dimensional spaces stable and effective. The combination of these two innovations allows for seamless, contact-rich manipulation. The human provides high-level guidance, and the robot executes the complex in-hand coordination required.

Why Frictionless AI Might Be Harmful

Published

on

Most people who regularly use AI tools would say they’re making their lives easier. The technology promises to streamline and take over tasks both professionally and personally—whether that’s summarizing documents, drafting deliverables, generating code, or even offering emotional support. But researchers are concerned AI is making some tasks too easy, and that this will come with unexpected costs.

In a commentary titled Against Frictionless AI, published in Communications Psychology on 24 February, psychologists from the University of Toronto discuss what might be lost when AI removes too much effort from human activities. Their argument centers on the idea that friction—difficulty, struggle, and even discomfort—plays an important role in learning, motivation, and meaning. Psychological research has long shown that effortful engagement can deepen understanding and strengthen memory, sometimes described as “desirable difficulties.”

The authors worry that AI systems capable of instantly producing polished answers or highly responsive conversation may bypass these processes of learning and motivation. By prioritizing outcomes over effort, AI could weaken the experiences that help people develop skills, build relationships, and find meaning in their work.

IEEE Spectrum spoke with the paper’s lead author, Emily Zohar, an experimental psychology Ph.D. student, about why she and her coauthors (psychologists Paul Bloom and Michael Inzlicht) argue that friction matters—and what a more human-centered approach to AI design could look like.

Advertisement

When you say “friction,” what do you mean, from both a cognitive and an interpersonal standpoint?

Zohar: We define friction as any difficulty encountered during goal pursuit. In the context of work, it involves mental effort—rumination and persistence, staying on a problem for some time, and this helps solidify the idea and the creative process.

In relationships, friction involves disagreement, compromise, misunderstanding, a back and forth that is natural where you don’t always see eye to eye, and it helps you broaden your horizons. Even the feeling of loneliness is important. It motivates you to find social interactions. So having these negative feelings and difficulty is important in the social context.

Given that definition, what do you mean by “frictionless” AI?

Advertisement

Zohar: Frictionless AI refers to the excessive removal of effort from cognitive and social tasks. With AI, as we typically use it, it’s really easy to go from ideation right to the end product. You ask AI to solve something with one prompt, and it completes the whole thing. This is a problem because it takes away the intermediate steps that really drive motivation and learning, and it prioritizes outcome over process. Rather than working through the steps, AI does that meaningful work for you.

There’s a lot of research showing work products are better with AI. That makes sense, it has all this knowledge, but it does worry us as it may be eroding something essential that will have long-term consequences. If you’re faced with the same problem and AI is removed, you don’t have the required knowledge to know how to face the problem next time.

You argue that removing friction can harm learning and relationships. What role do effort and struggle play in human development?

Zohar: In learning, the term is “desirable difficulties.” It’s the idea of effort and work, not just any effort but manageable effort. Facing problems that you can overcome, but you have to work at them a bit, that’s the key idea of friction. We don’t want you to face insurmountable problems. We want you to work hard, but still be able to overcome it. This helps you really digest information and learn from it.

Advertisement

In interpersonal relationships, you have to face some difficulties to see other perspectives and learn from them, and learn to be accepting of others. If you’re used to an AI reinforcing all your ideas and being sycophantic, you’ll come into the real world and you won’t be used to seeing other ideas. You won’t know how to interact socially because you’ll expect people to always be on your side and agree with you. You won’t learn that life doesn’t always go exactly how you expect it to, and conversations don’t always go the way you want them to.

AI’s Impact on Creative Processes

A lot of technologies have historically aimed to reduce effort: calculators, washing machines, spellcheck. What’s different about AI?

Zohar: Past technologies have mostly focused on reducing physical effort. We don’t have to go down to the lake to wash our laundry anymore. [Past technologies] took away the mundane tasks that weren’t driving our learning and growth, they were just adding unneeded obstacles and taking away time from more important tasks.

But AI is taking away effort from creative and cognitive processes that drive meaning, motivation, and learning. That’s a key difference, because it’s not taking away friction from tasks that don’t serve us. It’s taking away friction from experiences that are really important and integral to our development.

Advertisement

Are there contexts where AI is already removing beneficial friction? How might the impacts of reduced friction show up over time?

Zohar: One clear example is writing. People increasingly rely on AI to draft everything from emails to essays, removing many instances of beneficial friction. Research shows that people trust responses less when they learn they were written by AI, judge AI-generated products as less creative and less valuable, and have greater difficulty remembering their own work products when they were produced with AI assistance. Outsourcing writing to AI strips away both social and cognitive friction.

Vibe coding is another good example. If you’re a programmer, coding is integral to what drives your meaning. People get meaning out of their work, and if you’re substituting that with AI, it could be detrimental. The negative impact of frictionless AI is that it takes away friction from things that are really important to who you are as a person, and your skills.

One area I worry about a lot is adolescents using AI in general. It’s a really important developmental period to learn and grow and find the path you’ll follow. So if you don’t have these effortful interactions with work and relationships that teach you how to think, this will have long-term detrimental impacts. They might not be able to think critically in the same way, because they never had to before. If they’re turning to AI for social relationships at such a young age, that could really erode important skills they should be learning at that age.

Advertisement

What is productive friction?

Zohar: Friction goes along a continuum. With too little friction, you’re not getting learning and motivation. Too much friction and the task becomes overwhelming. Productive friction falls right in the middle, where struggle leads to achievement. It’s effortful but possible, and it requires you to think critically and work on a problem for some time or face some difficulty in the process.

An example we used in the paper is the difference between taking a chairlift and hiking up a mountain. They both get to the top, but with the chairlift, you don’t get any growth benefits, while the hiker’s climb involves difficulties and a sense of achievement. It becomes much more of an experience and a learning opportunity versus the person who just went up the chairlift effortlessly.

Do you envision AI that sometimes deliberately slows people down or asks them to do part of the work themselves?

Advertisement

Zohar: It’s important in behavioral science to think about the default option, because people don’t usually change their default. So right now, the default in AI is to give you your answer and probe you to keep going down the rabbit hole. But I think we could think about AI in a different way. Maybe we can make the default more constructive. Instead of just jumping to the answer, it’s more of a process model where it helps you think about the problem and teaches you along the way, so it’s more collaborative rather than a one-stop shop for the answer.

How might users of these systems and the companies developing them feel about such a design shift?

Zohar: For the makers of these systems, the biggest concern is the pushback. People are used to going in and just getting the answer, and they might be really resistant to a design that makes them work more for it. But it might feed more engagement, because you have to go back and forth and find the answer together.

Ultimately I think it has to come from the companies making these models, if they think [a more friction-full design] would help people. Friction-full AI is more of a long-term product. It’s hard to say if that would motivate companies to change their models to include moderate friction. But in the long term, I think this would be beneficial.

Elon Musk Announces $20B ‘Terafab’ Chip Plant in Texas To Supply His Companies

Published

on

“Billionaire Elon Musk has announced plans to build a $20 billion chip plant in Austin, Texas” reports a local news station:

Musk announced on Saturday night during a livestream on his social media platform X that the plant, called “Terafab,” will be built near Tesla’s campus and gigafactory in eastern Travis County. The long-anticipated project is a joint venture between Musk-owned properties Tesla, SpaceX and xAI… The Terafab plant is expected to begin production in 2027.

Musk “has said the semiconductor industry is moving too slow to keep up with the supply of chips he expects to need,” writes Bloomberg — quoting Musk as saying “We either build the Terafab or we don’t have the chips, and we need the chips, so we build the Terafab.”

Musk detailed some specific plans, including producing chips that can support 100 to 200 gigawatts a year of computing power on Earth, and chips that can support a terawatt in space, but gave no timelines for the facility or its output… The facility is expected to make two types of chips, one of which will be optimized for edge and inference, primarily for his vehicle, robotaxi and Optimus humanoid robots. The other will be a high-power chip, designed for space that could be used by SpaceX and xAI… Musk said he expects xAI to use the vast majority of the chips.

During the presentation, Musk also unveiled a speculative rendering of a future “mini” AI data center satellite, one piece of a much larger satellite system that he wants SpaceX to build to do complex computing in space. In January, SpaceX requested a license from the Federal Communications Commission to launch one million data center satellites into orbit around Earth. Musk said that the mini satellite he revealed would have the capacity for 100 kilowatts of power. “We expect future satellites to probably go to the megawatt range,” Musk said.

Raising money to build and launch AI data centers in space is one of the driving forces behind SpaceX’s planned IPO later this year. SpaceX is expected to raise as much as $50 billion in a record-setting IPO this summer which could value it at more than $1.75 trillion, Bloomberg News reported earlier.

Solar Panels Freeze a Bucket of Water by Day to Run Free Air Conditioning at Night

Published

on

Solar Power Ice Air Conditioning
Summers in Florida are terrible, forcing people to get creative in order to stay cool without breaking the bank or overloading the electricity grid. Hyperspace Pirate took on the problem and came up with a clever mechanism that absorbs solar energy throughout the day and stores it as ice for use when cooling is required, bingo.



Three regular 100-watt solar panels are put on the back of a vehicle and simply plug into a normal charge controller connected to a 35-amp-hour lead-acid battery. Once the battery is fully charged, the microcontroller activates an inverter, which powers a miniature refrigerator compressor. That compressor sucks up around 80 to 100 watts and begins to draw heat from a 2-gallon water bucket coated in substantial insulation, as we’re talking one-inch foam panels and a lot of fiberglass wool here.

Sale


Portable Solar Generator, 300W Portable Power Station with Foldable 60W Solar Panel,110V Pure Sine Wave…
  • Portable Generator with 60W Solar Panel Included: with a big battery pack, ZeroKor 300W power stations Generator are powerful enough to charge…
  • Multiple Charging outlets for camping gear with SOS Flashlight: with 2* 300W Max AC outlets, 1* DC port (9V-12.6V/10A max ), 3* 5V/3A Max USB ports…
  • Multiple Charging Optional, Solar Panel 60W Included: ZeroKor portable power bank generator can be recharged by wall AC outlet, DC5521 Solar Panel…

Solar Power Ice Air Conditioning
Hours under the hot afternoon sun transform the entire bucket into a solid block of ice. The phase transition from liquid water to ice manages to store approximately 2.5 million joules of energy in that rather normal container. When the procedure is reversed, these numbers add up to adequate cooling capacity to provide around 700 watts of chilled air for an hour. On the cooling side, a pump circulates a 50-50 mix of water and ethylene glycol via twenty feet of copper tubing coiled deep inside the frozen block. That liquid sucks cold from the ice and drains to a standard automobile radiator with a little fan attached. Only a few watts are required to run the pump and fan, so the battery may continue to provide power even after sunset.

Solar Power Ice Air Conditioning
The insulation around the bucket is so strong that heat only leaks in at about 7 or 8 watts. Testing revealed that the ice remained frozen solid for several days, with almost no evidence of melting. The microcontroller’s voltage logging revealed that the compressor was kicking in at 12.9 volts and shutting out at 11.1 volts to keep the battery happy, while solar was still charging. The real-world trial put it through its paces inside the truck cab. Even on a warm day, circulating that refrigerated glycol significantly reduced the inside temperature over a few hours. The entire setup is slightly heavier than a basic battery pack, but it is still suitable for mobile use or small structures where grid ties do not seem like an option.

Solar Power Ice Air Conditioning
Scaling up becomes easy from here on out, since adding more solar panels and a larger water tank increases the output to several kW. Cabins and recreational vehicles were already an appropriate fit, both in terms of size and energy requirements. As an added plus, a whole house may use the system as an extra cooling source when it’s really hot outside without having to transfer any excess electricity back to the power company.

Solar Power Ice Air Conditioning
Water carries the load rather than all those chemical batteries. So the storage remains compact while the pricing remains affordable. One cubic metre of ice has roughly 93 kilowatt-hours of cooling power and weighs less than a stack of cells. The compressor runs on standard n-butane refrigerant that has been charged into a closed loop. It never interacts with the glycol side. Every last piece was built with off-the-shelf parts, some copper fabrication, and some custom code for monitoring.

AI enters the chat: New Seattle dating app relies on tech to facilitate meaningful human connections

Published

on

Screen grabs from the Lamu app show various interactions with AI, including, from left, answering profile questions, receiving a “love score” and completed profile, and discussing date location options. (Lamu Images)

Ada Jin was suffering from dating app fatigue. She was tired of the constant swiping and the hook-up mentality that’s prevalent on many legacy platforms. She wanted a product that helped facilitate intentional dating and respected people’s time and effort.

So she turned to AI to help humans better connect.

Jin is the founder of Lamu, a Seattle-based digital matchmaking service that relies on artificial intelligence to learn about users and help facilitate conversations and meaningful dates between matches.

“What we’re trying to solve is helping people find the right person more efficiently,” Jin said, adding that unlike traditional human matchmaker services which can cost thousands of dollars, Lamu is “way, way, way more affordable.”

Lamu charges a $9.99 registration fee to get people into the matching pool, and to scare off fake or deceptive profiles.

Users start with an onboarding in which they answer questions presented by Lamu’s AI. Jin said they’ve tried to make it fun and interactive, allowing people to communicate with the AI, even by voice. The AI generates a “love score” and then searches for matches, revealing one or two per week to avoid the paralysis of too many choices. Initial revealed information between matches includes first name, age, city, occupation and some hobbies or interests.

If the matches are mutually interested, the AI puts them in a group chat where the matchmaker serves as “wingman” to help things progress. Photos are only shared at this point so that users have the “full picture” before they choose to meet in person.

Jin thinks Seattle is the perfect place to build such a startup rather than the Bay Area where she previously worked as an engineer at Meta and TikTok. She says Lamu and AI could help penetrate the infamous “Seattle freeze” and loneliness in general.

While San Francisco has more founders and a more active investor base around consumer startups, Jin is invested in the Seattle region’s natural beauty and outdoor pursuits.

Since moving to the city last June, she’s been involved in Seattle’s startup community, which helped her meet her co-founder, Georgiy Lapin, a computer science student at the University of Washington.

Lamu isn’t the only player turning to AI to fix a broken dating culture. The industry’s giants are also utilizing AI in a variety of ways to address some of the issues Jin described.

At its first-ever product keynote earlier this month, Tinder unveiled a number of features including “Chemistry,” an AI-powered personalization layer that uses a scan of a user’s camera roll and interactive Q&As to curate daily recommendations. “Are You Sure?” is another tool using context-aware AI to detect and blur inappropriate messages before they’re even seen. Meanwhile, Bumble recently launched its “Deception Detector,” which the company says has successfully blocked 95% of accounts identified as spam or scams.

As Lamu grows, Jin is betting that users are ready to trade endless swiping for a slower, more deliberate pace. Her goal isn’t to keep people on the platform, but to provide the one thing legacy apps often lack: a sense of direction.

“I really need more clarity,” Jin said, reflecting on the burnout that led her to build the app. “I’d rather just do it once and find the right person.”
