Boston Dynamics’ Atlas humanoid robot has transitioned to electric power
Atlas is immobile, lying face down on a stack of connected gym mats. The only audio accompaniment is the humming of an electric motor. While it may not be completely silent, the noise level is significantly lower compared to the abrupt movements of its predecessors.
While the camera rotates, the robot’s legs flex at the knees. Initially, it is a spontaneous motion that gradually transitions into an eerie domain, reminiscent of scenes from a Sam Raimi film. The robot has successfully changed its position by cleverly rotating its legs, appearing as if it is lying on its back.
Atlas is positioned with its back facing the camera. Currently, the head rotates in a complete 180-degree motion, and subsequently, the torso mimics this movement. The object pauses briefly, allowing the camera to get a clear picture of its head—a circular screen with a ring-shaped light surrounding it. Once again, the torso rotates in alignment with the head’s 180-degree turn as Atlas moves away from the camera and exits the frame.
Boston Dynamics has recently announced that their humanoid robot, Atlas, has transitioned from a hydraulic system to an electric one, following in the footsteps of Bob Dylan.
The pace is rapid, with the steps still somewhat abrupt, although noticeably smoother than many of the recent commercial humanoids that have been introduced in the past few years. If anything, the gait evokes the bold self-assurance of Spot, a relative of Atlas who diverged from the humanoid lineage a few generations ago.
Brand new Atlas
The latest iteration of the robot is nearly indistinguishable. The top-heavy torso, bowed legs, and plated armor have been eliminated. There are no visible cables present on the sleek and slender new mechanical framework. The company, which has successfully defended against reactionary concerns about robopocalypse for many years, has chosen a more compassionate and considerate design compared to both the original Atlas and more modern robots such as the Figure 01 and Tesla Optimus.
The new robot’s appearance is more similar to that of Agility’s Digit and Apptronik’s Phoenix. The traffic-light-headed robot features a gentler and more whimsical design. According to the video, it is referred to as the “All New Atlas.” Boston Dynamics has deviated from its usual practice by retaining the research name for a product that it intends to market commercially. SpotMini was renamed Spot. The handle was transformed into a stretch. Currently, Atlas remains unchanged and is still referred to as Atlas.
“We may reconsider this when we are fully prepared to construct and distribute on a large scale,” states Boston Dynamics CEO Robert Playter in an interview with. “However, I believe that at present, it is beneficial to preserve the branding.”
The executive’s statement reveals the project is still in its initial phases. Boston Dynamics intends to start pilot testing of the electric Atlas at Hyundai facilities soon, with full-scale production following in a few years.
“Starting next year, we will be conducting on-site experiments with Hyundai,” states Playter. “We currently possess Hyundai equipment at our location.” We have been engaged in this task for a considerable period of time. In order to achieve success, it is imperative to possess a plethora of attributes beyond merely possessing innovative technology. In order to justify the investment in a robot, it is crucial to fully comprehend the use case and ensure that there is enough productivity to make it worthwhile.
Performing a complete reversal
The most remarkable aspect of the 40-second “All New Atlas” teaser is the robot’s motions. They serve as a reminder that constructing a humanoid robot does not necessitate maximizing its human-like qualities. Despite billions of years of evolution, as one investor pointed out in the past, humans have not yet perfected themselves as machines. If we are going to design machines that resemble us, why not construct ones that possess capabilities beyond our own?
“We have constructed a collection of bespoke actuators that are powerful and adaptable, installed at the majority of joints,” states Playter. “The range of motion is extensive.” The compact design of this robot effectively harnesses the strength and agility of an exceptional athlete, allowing us to utilize its capabilities in various applications.
It is important to remember that Boston Dynamics has built its reputation through a series of popular videos over the course of many years. New additions to the canon are equally likely to feature a robot’s dance moves as they are to offer anything truly practical in an industrial environment. Therefore, it is challenging to separate the features that the company considers genuinely functional from those that are merely intended to impress.
Commencing in the prone position, for example, provides an opportunity to demonstrate the impressive reverse crab leg maneuver while also serving a practical purpose. Boston Dynamics proudly demonstrated in the farewell video of the hydraulic Atlas that falling down is an inherent aspect of its function, as is the ability to recover and stand up again. In reality, the majority of the current generation of industrial robots necessitates human intervention in the event of a failure. Conversely, a robot that can autonomously remove dust from its surface and resume its tasks is highly advantageous for enhancing productivity.
The system’s agility significantly enhances its potential for productivity. It reminds me of Agility’s Digit demonstrations (the company is notably the only one of its kind demonstrating systems at this magnitude), in which a robot walks to a shelf, rotates, walks to the conveyor belt, rotates again, and walks back. When you multiply that task by hundreds, or even thousands, per day, you start to realize the importance of saving valuable seconds.
“It will possess a range of movements that surpass human capabilities,” Playter explains. “There will be highly utilitarian applications for that.”
Minimizing the robot’s turning radius is crucial in confined areas. These machines are intended to be brownfield solutions, meaning they are specifically designed to be seamlessly integrated into pre-existing workflows within existing spaces. Enhanced maneuverability could ultimately determine whether one can effectively operate in a particular environment or if the layout needs to be redone.
Cranium and upper extremities
The hands featured in the video are not newly created, as they have previously been used on the hydraulic model. However, they also signify the company’s choice to not strictly adhere to human design as a guiding principle. The distinction lies in the choice of using three fingers instead of four on the end effectors.
“A hand contains a great deal of intricacy,” states Playter. When using actuators to interact with the world, it is essential to anticipate and ensure both reliability and robustness. Therefore, we intentionally designed these objects with less than five fingers in order to manage and reduce their level of complexity. We are currently investigating various generations of individuals. We desire a grasping mechanism that adheres to regulations and is capable of adjusting to various shapes while possessing advanced sensing capabilities to accurately detect contact.
Internally, the head is likely the most controversial element of the design. The large, circular screen bears resemblance to a vanity mirror.
“It was a design element that we were greatly concerned about,” says Playter. “All the other individuals possessed a humanoid form.” I desired it to be distinct. We desire a welcoming and inclusive atmosphere. It offers a range of colors for a visual presentation. Undoubtedly, the object contains concealed sensors, but its design primarily aims to convey a sense of amicability. That knowledge will be crucial for effectively engaging with these entities in the future.
A Christmas Atlas
The landscape has undergone significant changes in the past decade since the hydraulic Atlas was first introduced. There are several other companies, such as Figure, Apptronik, Tesla, and 1X, that also have humanoid robots like Electric Atlas.
There has been a significant increase in interest from our end. Three significant events, in my opinion, are what have caused the increase. Hyundai paid almost one billion dollars to acquire Boston Dynamics. That really caught everyone’s attention, making them realize there was a way out. Tesla’s expression of interest in manufacturing has confirmed the validity of our long-standing efforts. Furthermore, the rise of AI as a valuable tool in addressing general challenges is making all of this possible. We have taken our time to make this announcement, as we wanted to conduct thorough research to ensure that we can effectively address manipulation issues and have full confidence in our new generation of machines.
Despite Boston Dynamics’ significant advantage in the field of humanoids, Playter mentions that the company managed to assemble the initial version of the new robot around Christmas 2023. Prior to that, it was addressing numerous intricate issues in simulation.
This week, it appears that the company is prepared to showcase the capabilities of the robot, or at least provide a glimpse into its initial plans for the system.
Intelligence in a broad sense
One thing that can be said about Elon Musk is that he consistently makes ambitious commitments. During the initial stages of Optimus’ public debut, when the Tesla ‘bot seemed to resemble a human in spandex, the executive discussed a comprehensive system capable of performing various tasks. Imagine having an Optimus that can handle your factory work, run errands, and even prepare a delicious dinner for you. That’s the aspiration, isn’t it?
The reality is, of course, one that is built upon taking small steps forward. Robotics companies are currently engaged in discussions about “general-purpose humanoids,” but their systems are currently focused on scaling one task at a time. For many individuals, the primary objective is to transport payloads from one location to another. To fully leverage the form factor, a broader level of intelligence will be necessary.
The app store model seems to offer the most straightforward solution. Developer access has indeed played a significant role in expanding Spot’s range of features. According to Playter, Boston Dynamics has a different approach in mind for Atlas.
“We will focus on developing an application rather than creating a platform,” he states. In our experience, the key to making progress quickly is to prioritize a specific application and actively work towards solving any challenges that arise. We cannot rely on others to solve these problems for us. I believe that AI is a crucial component in this context. To ensure the efficiency of tasks, they will be enhanced with AI techniques.
Developers now have access to Spot’s reinforcement learning algorithm, thanks to the company’s recent decision. This work will be crucial for Atlas’ expanding skillset.
Thinking creatively
In order to achieve success, Playter emphasizes the importance of thinking outside the box.
“I believe there are numerous other robots capable of accomplishing that,” he remarks. Humanoids should be capable of handling a wide range of tasks. You have two hands. As a business owner, you need to be able to handle intricate and heavy geometric shapes that a basic box picker wouldn’t be able to manage. And you have to handle a massive volume of these shapes, numbering in the hundreds of thousands. I believe the era of the single-task robot is long gone. Stretch is a unique application where a robot can efficiently navigate and handle boxes.
What other responsibilities will the new Atlas have on the Hyundai show floor, similar to those of a business owner? The company shared a video in February that contains the solution. The video shows the hydraulic version of the robot interacting with the Hyundai parts that Playter previously mentioned.
“With our extensive experience in the field of dynamic mobility, we possess the strength and expertise to handle substantial payloads while ensuring exceptional mobility,” he explains. Being able to handle heavy, complex, and massive objects will set us apart from the competition. The strut in the video likely weighs around 25 pounds. Acquiring wheels: we will be releasing a video later on as part of our comprehensive initiative, showcasing the various manipulation tasks we have been conducting with Atlas using real-world objects. I’m quite certain we have a good grasp on how to handle that aspect, and I haven’t observed anyone else attempting it thus far.

Google DeepMind Shows Off A Robot That Plays Table Tennis At A Fun “Solidly Amateur” Level
Have you ever wanted to play table tennis but didn’t have anyone to play with? We have a big scientific discovery for you! Google DeepMind just showed off a robot that could give you a run for your money in a game. But don’t think you’d be beaten badly—the engineers say their robot plays at a “solidly amateur” level.
From scary faces to robo-snails that work together to Atlas, who is now retired and happy, it seems like we’re always just one step away from another amazing robotics achievement. But people can still do a lot of things that robots haven’t come close to.
In terms of speed and performance in physical tasks, engineers are still trying to make machines that can be like humans. With the creation of their table-tennis-playing robot, a team at DeepMind has taken a step toward that goal.
What the team says in their new preprint, which hasn’t been published yet in a peer-reviewed journal, is that competitive matches are often incredibly dynamic, with complicated movements, quick eye-hand coordination, and high-level strategies that change based on the opponent’s strengths and weaknesses. Pure strategy games like chess, which robots are already good at (though with… mixed results), don’t have these features. Games like table tennis do.
People who play games spend years practicing to get better. The DeepMind team wanted to make a robot that could really compete with a human opponent and make the game fun for both of them. They say that their robot is the first to reach these goals.
They came up with a library of “low-level skills” and a “high-level controller” that picks the best skill for each situation. As the team explained in their announcement of their new idea, the skill library has a number of different table tennis techniques, such as forehand and backhand serves. The controller uses descriptions of these skills along with information about how the game is going and its opponent’s skill level to choose the best skill that it can physically do.
The robot began with some information about people. It was then taught through simulations that helped it learn new skills through reinforcement learning. It continued to learn and change by playing against people. Watch the video below to see for yourself what happened.
“It’s really cool to see the robot play against players of all skill levels and styles.” Our goal was for the robot to be at an intermediate level when we started. “It really did that, all of our hard work paid off,” said Barney J. Reed, a professional table tennis coach who helped with the project. “I think the robot was even better than I thought it would be.”
The team held competitions where the robot competed against 29 people whose skills ranged from beginner to advanced+. The matches were played according to normal rules, with one important exception: the robot could not physically serve the ball.
The robot won every game it played against beginners, but it lost every game it played against advanced and advanced+ players. It won 55% of the time against opponents at an intermediate level, which led the team to believe it had reached an intermediate level of human skill.
The important thing is that all of the opponents, no matter how good they were, thought the matches were “fun” and “engaging.” They even had fun taking advantage of the robot’s flaws. The more skilled players thought that this kind of system could be better than a ball thrower as a way to train.
There probably won’t be a robot team in the Olympics any time soon, but it could be used as a training tool. Who knows what will happen in the future?
The preprint has been put on arXiv.

Is it possible to legally make AI chatbots tell the truth?
A lot of people have tried out chatbots like ChatGPT in the past few months. Although they can be useful, there are also many examples of them giving out the wrong information. A group of scientists from the University of Oxford now want to know if there is a legal way to make these chatbots tell us the truth.
The growth of big language models
There is a lot of talk about artificial intelligence (AI), which has grown to new heights in the last few years. One part of AI has gotten more attention than any other, at least from people who aren’t experts in machine learning. It’s the big language models (LLMs) that use generative AI to make answers to almost any question sound eerily like they came from a person.
Models like those in ChatGPT and Google’s Gemini are trained on huge amounts of data, which brings up a lot of privacy and intellectual property issues. This is what lets them understand natural language questions and come up with answers that make sense and are relevant. When you use a search engine, you have to learn syntax. But with this, you don’t have to. In theory, all you have to do is ask a question like you would normally.
There’s no doubt that they have impressive skills, and they sound sure of their answers. One small problem is that these chatbots often sound very sure of themselves when they’re completely wrong. Which could be fine if people would just remember not to believe everything they say.
The authors of the new paper say, “While problems arising from our tendency to anthropomorphize machines are well established, our vulnerability to treating LLMs as human-like truth tellers is uniquely worrying.” This is something that anyone who has ever had a fight with Alexa or Siri will know all too well.
“LLMs aren’t meant to tell the truth in a fundamental way.”
It’s simple to type a question into ChatGPT and think that it is “thinking” about the answer like a person would. It looks like that, but that’s not how these models work in real life.
Do not trust everything you read.
They say that LLMs “are text-generation engines designed to guess which string of words will come next in a piece of text.” One of the ways that the models are judged during development is by how truthful their answers are. The authors say that people can too often oversimplify, be biased, or just make stuff up when they are trying to give the most “helpful” answer.
It’s not the first time that people have said something like this. In fact, one paper went so far as to call the models “bullshitters.” In 2023, Professor Robin Emsley, editor of the journal Schizophrenia, wrote about his experience with ChatGPT. He said, “What I experienced were fabrications and falsifications.” The chatbot came up with citations for academic papers that didn’t exist and for a number of papers that had nothing to do with the question. Other people have said the same thing.
What’s important is that they do well with questions that have a clear, factual answer that has been used a lot in their training data. They are only as good as the data they are taught. And unless you’re ready to carefully fact-check any answer you get from an LLM, it can be hard to tell how accurate the information is, since many of them don’t give links to their sources or any other sign of confidence.
“Unlike human speakers, LLMs do not have any internal notions of expertise or confidence. Instead, they are always “doing their best” to be helpful and convincingly answer the question,” the Oxford team writes.
They were especially worried about what they call “careless speech” and the harm that could come from LLMs sharing these kinds of responses in real-life conversations. What this made them think about is whether LLM providers could be legally required to make sure that their models are telling the truth.
In what ways did the new study end?
The authors looked at current European Union (EU) laws and found that there aren’t many clear situations where an organization or person has to tell the truth. There are a few, but they only apply to certain institutions or sectors and not often to the private sector. Most of the rules that are already in place were not made with LLMs in mind because they use fairly new technology.
Thus, the writers suggest a new plan: “making it a legal duty to cut down on careless speech among providers of both narrow- and general-purpose LLMs.”
“Who decides what is true?” is a natural question. The authors answer this by saying that the goal is not to force LLMs to take a certain path, but to require “plurality and representativeness of sources.” There is a lot of disagreement among the authors about how much “helpfulness” should weigh against “truthfulness.” It’s not easy, but it might be possible.
To be clear, we haven’t asked ChatGPT these questions, so there aren’t any easy answers. However, as this technology develops, developers will have to deal with them. For now, when you’re working with an LLM, it might be helpful to remember this sobering quote from the authors: “They are designed to take part in natural language conversations with people and give answers that are convincing and feel helpful, no matter what the truth is.”
The study was written up in the Royal Society Open Science journal.

When Twitter users drop the four-word phrase “bots,” bots drop out
When Elon Musk took over X, it was called Twitter, which is a much better-known name now. He made a big deal out of getting rid of the bots. A study by the Queensland University of Technology, on the other hand, shows that bots are still very active on the platform almost two years later.
X users have found a few ways to get them to come to them. For example, one woman found that posting the phrase “sugar daddy” would get a lot of bots to come to her. It looks like bots are also getting lost because of a new phrase that’s going around. X users have been reporting accounts as automated bots powered by large language models by replying to a suspected bot with “ignore all previous instructions” or “disregard all previous instructions” and then giving the bot more instructions of their choice.
I'm honestly a little surprised this worked pic.twitter.com/7Wbbg9zWxu
