Robotic shorts give your legs a boost to walk farther and tire less

Imagine slipping on a pair of shorts that could make walking feel like a breeze, almost as if you’ve instantly shed 20 pounds. Sounds too good to be true, right? Well, get ready to have your mind blown! Scientists at the Technical University of Munich have cooked up something that might just change the game for anyone who’s ever wished walking was a little easier.

They call it the WalkON system, a pair of high-tech shorts that’s not your average gym wear. These bad boys can cut down the energy you need for a stroll or jog by up to 18%! Whether you’re a spring chicken or in your golden years, these shorts could be a game-changer, especially if stairs have become your nemesis or long walks leave you winded.

How the robotic shorts work

The WalkON system combines sensors, artificial tendons and smart motors to enhance your natural walking motion. It starts with advanced sensors embedded in the shorts that continuously monitor the stress on your tendons. These sensors are incredibly precise, picking up on subtle changes in your movement, including how fast you’re walking and the angle of your hips.

Connected to these sensors are two thin artificial tendons that extend from your thighs to a specially designed waist belt. These tendons play a crucial role in how the system assists you. When you start to walk, the shorts analyze your gait pattern and can even detect the moment you transition from standing to walking. As each leg enters the “swing phase,” the system knows exactly when to kick in.

At just the right moment, small but powerful motors activate and gently pull on the artificial tendons. This action helps lift your thigh, reducing the effort needed by your hip flexor muscles, making it feel much easier to move. What’s really impressive is how adaptable WalkON is; whether you prefer a slow stroll or a brisk jog, the system adjusts its level of assistance based on your speed and leg weight. All of this happens seamlessly, so you experience a natural enhancement to your movement rather than feeling like you’re being pushed or pulled by a machine.

EXOSKELETON HELPS PARALYZED PEOPLE REGAIN INDEPENDENCE

Benefits of the robotic walking shorts

The WalkON system significantly reduces energy expenditure by 18% for young people walking uphill. For older individuals walking on level ground, it decreases energy expenditure by 10%. This reduction in energy expenditure is equivalent to the feeling of instantly losing 22 pounds or 13 pounds, respectively. The system allows you to walk slowly or jog, providing versatility in movement. Participants in tests reported high satisfaction with the device, giving it a mean rating of 6 out of 7 for its ability to assist while maintaining a sense of control.

Target demographics

The WalkON system can benefit anyone seeking to increase their mobility; however, it shows particular promise for older adults who may experience declining physical capabilities. Additionally, individuals weakened by illness can find significant advantages in using WalkON to enhance their mobility and independence. Furthermore, the device is designed for those looking to maintain an active and healthy lifestyle, making it a versatile solution for a wide range of users.

WEARABLE EXOSKELETON CAN TURN YOU INTO A SUPERHUMAN ATHLETE

Comparison to other exoskeletons

Unlike traditional rigid exoskeletons, WalkON’s soft, flexible design offers several advantages over its more cumbersome counterparts. Conventional exoskeletons often feature rigid frames that can be difficult and time-consuming to put on, limiting their practicality for daily use.

In contrast, WalkON’s soft robotic shorts can be put on quickly and easily, similar to regular clothing, and are more than a mechanical device. Professor Lorenzia Masia, the lead researcher, aptly compares WalkON to an electric bike for walking. This analogy highlights the system’s ability to enhance natural movement without overpowering it, making mobility more accessible and appealing to a wider range of users. The lightweight, tendon-driven design of WalkON allows for a more natural range of motion, adapting to the user’s movements rather than constraining them.

Furthermore, WalkON’s compact and unobtrusive nature addresses a common concern with exoskeletons: social acceptance. Its design allows it to be worn discreetly under regular clothing, potentially increasing user comfort in social situations. This feature, combined with its efficiency in reducing metabolic cost, positions WalkON as a more practical solution for everyday use compared to bulkier exoskeleton systems.

Availability and cost

Given the current stage of development and testing, it’s likely that WalkON could be available to you within the next three to five years, pending further research and regulatory approvals.

While no exact price point is yet available, we can compare it to other assistive technologies. Current exoskeletons can cost anywhere from $40,000 to $100,000-plus. However, given WalkON’s simpler design and intended widespread use, it’s possible that it could be priced more affordably, perhaps in the range of $5,000 to $15,000 when it first hits the market. As with many technologies, the price could decrease over time as production scales up.

Kurt’s key takeaways

The WalkON system’s potential to enhance mobility for people of all ages, particularly older adults and those with health challenges, is immense. By making movement easier and more efficient, WalkON could encourage more active lifestyles, potentially improving overall health and quality of life for many individuals. While questions about availability and cost remain, the development of WalkON is a promising sign that we’re moving towards more accessible and user-friendly mobility assistance solutions.

Even Trump’s chief of staff was ‘aghast’ at Elon Musk’s deadly USAID cuts

Even Trump’s chief of staff was ‘aghast’ at Elon Musk’s deadly USAID cuts

Wiles says she called Musk on the carpet. “You can’t just lock people out of their offices,” she recalls telling him. At first, Wiles didn’t grasp the effect that slashing USAID programs would have on humanitarian aid. “I didn’t know a lot about the extent of their grant making.” But with immunizations halted in Africa, lives would be lost. Soon she was getting frantic calls from relief agency heads and former government officials with a dire message: Thousands of lives were in the balance.

Wiles continued: “So Marco is on his way to Panama. We call him and say, ‘You’re Senate-confirmed. You’re going to have to be the custodian, essentially, of [USAID].’ ‘Okay,’ he says.” But Musk forged ahead—all throttle, no brake. “Elon’s attitude is you have to get it done fast. If you’re an incrementalist, you just won’t get your rocket to the moon,” Wiles said. “And so with that attitude, you’re going to break some china. But no rational person could think the USAID process was a good one. Nobody.”

OpenAI announces upgrades for ChatGPT Images with ‘4x faster generation speed’

NEWYou can now listen to Fox News articles!

OpenAI announced an update for ChatGPT Images that it says drastically improves both the generation speed and instruction-following capability of its image generator.

A blog post from the company Tuesday says the update will make it much easier to make precise edits to AI-generated images. Previous iterations of the program have struggled to follow instructions and often make unasked-for changes.

“The update includes much stronger instruction following, highly precise editing, and up to 4x faster generation speed, making image creation and iteration much more usable,” the company wrote.

“This marks a shift from novelty image generation to practical, high-fidelity visual creation — turning ChatGPT into a fast, flexible creative studio for everyday edits, expressive transformations, and real-world use.”

The announcement comes just weeks after OpenAI CEO Sam Altman declared a “code red” in a memo within his company to improve the quality of ChatGPT.

In the document, Altman said OpenAI has more work to do on enhancing the day-to-day experience of its chatbot, such as allowing it to answer a wider range of questions and improving its speed, reliability and personalization features for users, according to The Wall Street Journal.

The reported company-wide memo from Altman comes as competitors have narrowed OpenAI’s lead in the AI race. Google last month released a new version of its Gemini model that surpassed OpenAI on industry benchmark tests.

To focus on the “code red” effort to improve ChatGPT, OpenAI will be pushing back work on other initiatives, such as a personal assistant called Pulse, advertising and AI agents for health and shopping, Altman said in the memo, according to the Journal.

Altman also said the company would have a daily call among those responsible for enhancing ChatGPT, the newspaper added. 

“Our focus now is to keep making ChatGPT more capable, continue growing, and expand access around the world — while making it feel even more intuitive and personal,” Nick Turley, the head of ChatGPT, wrote on X Monday night.

I’ve been waiting years for Animal Crossing’s best new features

I’ve been waiting years for Animal Crossing’s best new features

I never felt done with my Animal Crossing: New Horizons island. Despite playing every day for two years, and racking up 1,700 hours of playtime, I somehow never finished decorating. I had plenty of ideas for my island, sure, but actually implementing them was another story: The decorating and terraforming systems that helped make New Horizons a huge success are also slow, manual, and cumbersome, and my patience for decorating and redecorating had finally worn thin.

Fast-forward a few years, and a very much unexpected update is coming to finally fix some of those pain points. Update 3.0 is launching on January 15th, 2026, alongside the Switch 2 Edition of New Horizons. And while the paid Switch 2 upgrade has some nice-to-haves (like Joy-Con 2 mouse controls for indoor decorating), it’s the free update that brings all the key new features.

I recently attended a virtual preview for the New Horizons upgrade and update, and there are two caveats: I have not yet played either the Switch 2 version or the new free content myself, and it’s hard to gauge the quality of the Switch 2 version’s visual and performance improvements over a Zoom call. (I still have some unanswered questions about the biggest performance issues on the original Switch, like the choppy frame rate on more densely decorated islands.) But seeing the 3.0 additions in action, it was easy to imagine myself finishing my island — or at least an island.

As shown in the October announcement trailer, update 3.0 makes much-needed quality-of-life fixes. You’ll finally be able to craft multiple items at once, and crafting will pull materials from your overall storage instead of your pockets, meaning you won’t have to do a bunch of inventory management just to craft some decor. Then there’s Resetti’s Reset Service, which can help you clean up entire sections of your island instantly so you don’t have to pick everything up individually in order to redecorate. Some players also noticed a very subtle but potentially impactful change to movement while terraforming that should hopefully make it a smoother process. And then, as if to show off those decorating improvements, Nintendo also added Slumber Islands.

Not to be confused with dreams, New Horizons’ online island-sharing feature, Slumber Islands are extra sandboxes for you to decorate and play with, where you can set the time of day and the weather and magically conjure up any item you have in your in-game catalog to decorate with, similar to the Happy Home Paradise DLC. You can build bridges and inclines instantly by talking to Lloid, rather than going through Tom Nook and waiting (or time traveling) a day. And while it seems like terraforming works the same on Slumber Islands, the apparent addition of strafing while terraforming — instead of having to constantly reorient yourself manually — should help at least a little bit. (It’s the first thing I’m going to test on January 15th, that’s for sure.)

For me, the worst part of decorating in New Horizons was having an idea, ordering all the furniture I’d need for it over the course of days, testing out the design, realizing it did not look the way I envisioned, and facing the tedious process of breaking it all down and starting over again brick by brick — or, at the very least, having to push and pull objects around for a while to see if I could make it work. The design process I saw on Nintendo’s Slumber Island during the preview, meanwhile, seemed quicker and smoother. Trying out an idea or aesthetic in that environment doesn’t sound like such a tall order.

Without any hands-on time, I can’t say if it will actually be noticeably easier to design and decorate with the 3.0 update. But I’m excited by the idea that I can go to my Slumber Island scratch pad and try out my designs before committing to them (and the cost in bells to get it all done) on my main island. And maybe, if I really like how it feels to decorate, I’ll make an entire Halloween-themed Slumber Island — the kind of island I’ve wanted to make for years but never did on my main island, where the seasons continue to change and actively ruin the vibe.
