The Hypershell Exoskeleton Is Slimmer, Faster, and Still Not Built for Your Bad Knees
Who wants to complete their robot cosplay and simultaneously feel more capable of climbing cliffs? Hypershell, the company that brought us the original, relatively affordable sports exoskeleton, now has a few new metal suits for runners and hikers who need a little extra help on the trail.
There are three new models of exoskeleton, a $1,000 Hypershell X Pro S, a $1,500 Max S, and the $2,000 Ultra S. The Pro S was designed for “lighter” outdoor activity, while the Ultra S and Max S have access to up to 1,000W of max power output with 22N of torque with up to 15 mph (25 kph) max speed. The Ultra S also has the largest battery of the three, promising an 18-mile (30-kilometer) range per battery. The package comes with multiple batteries you can swap out when on the road.
The surprising thing about the Hypershell exoskeleton is that it works at all. The apparatus is centered around an armature of carbon fiber bars (the non-Ultra models use aluminum instead) that hugs your tailbone and legs just above the knees. Motors inside the back part of the exoskeleton follow your movements, so if you lift your leg, the Hypershell kicks in and pushes or pulls your limb, aiding your steps.
Hypershell’s new “S” series is still the same basic design as the last generation of exoskeletons. The main difference is how the device tracks body movement. The company told Gizmodo it had improved its AI motion detection to cut down on the delay between when you move your leg and when the motors kick in.
I personally had the chance to walk around with the device and climb several flights of stairs with different settings. There’s a very, very fine difference between the responsiveness of the new model and the old one. It overall adapted to my body faster and seemed a little more subtle than previous versions of the exoskeleton. That’s helped by its slightly slimmer design. Now, each bar that connects to your legs fits closer to your limbs. You still look like a cyborg who forgot their upper limbs, but some things can’t be helped.
The new Hypershell X Ultra S includes an automatic mode that supposedly uses AI to detect what kind of activity you’re doing and the terrain you’re running on. You can also use an app to manually select whether you’re running on a flat plane or tackling a steep cliff. The “S”-model Hypershell seemed to quickly guess when I was merely walking or facing an incline.
When I reviewed the original Hypershell Pro X, I thought it was an odd contraption despite how well it helped me tackle a moderately difficult hike. The device is built for and marketed to those who are already athletic. Hypershell likes to refer to its exoskeleton as a kind of “range extender” that will help push you to go even further than your body was previously capable of. Instead of doing a 15-mile hike or run, why not do 30 miles?
That means you lose out on some of the burn you hoped to achieve from your workout. Hypershell does not claim any of the new “S” models are medical devices. Gizmodo spoke to several Hypershell spokespeople, and they all reiterated that while it may help you with specific struggles with your leg, it won’t necessarily help you fix a knee injury or let a person with arthritis return to climbing mountains like a spry youth. It may help some people with certain types of leg or health issues, but Hypershell isn’t making any claims in that regard.
If you’re a backpacker going out on a miles-long, multi-day hike into the wilderness, the Hypershell might sound appealing. The thing to remember is that you’ll need to carry extra batteries around with you. The old adage that ounces become pounds on the trail holds true. If you run out of juice, you’ll be lugging multiple extra pounds of weight around with you.
Those who suit up in a Hypershell will inevitably feel more capable, so much so you may miss the exercise you could have gotten without an exoskeleton strapped to your legs.

‘Whatever Russia is testing, it’s sophisticated’: 2 Russian satellites get within 10 feet of each other in orbit
Two Russian spacecraft just demonstrated a very particular set of orbital skills.
The satellites, known as COSMOS 2581 and COSMOS 2583, got within just 10 feet (3 meters) or so of each other on April 28, according to COMSPOC, a Pennsylvania-based space situational awareness company.
"This wasn’t a coincidental pass — COSMOS 2583 performed several fine maneuvers to maintain this tight configuration," COMSPOC wrote in a May 1 X post, which featured an animation of the rendezvous.
The two satellites and a third one, COSMOS 2582, launched to low Earth orbit in February 2025 atop a Soyuz rocket. According to COMSPOC, all three of them were involved in the recent rendezvous and proximity operations (RPO), as was "Object F," a subsatellite previously deployed by COSMOS 2583.
During the 10-foot close approach, "COSMOS 2582 trailed the formation at sub-100 km range, while Object F passed within 15 km of 2582 and within 10 km of 2581 — neither maneuvered," wrote COMPSOC, which analyzed radar tracking data gathered by the California company LeoLabs.
"For context: in late 2025 to now, we tracked these same COSMOS satellites performing 3-object RPO," COMSPOC added in the May 1 X post. "Whatever Russia is testing, it’s sophisticated."
Such sophisticated orbital maneuvering is not exactly surprising; we’ve seen similar things from Russia before. For example, according to outside observers, the nation has operated multiple "inspector satellites," including COSMOS 2542, which made a close approach to a U.S. spy satellite in 2020.
The other major space powers have such capabilities as well. American and Chinese satellites have also been observed checking out other nations’ spacecraft high above Earth.

Brembo Brings Fluid-Free Brakes to Production Cars
https://www.autoblog.com/news/brembo-brings-fluid-free-brakes-to-production-cars
Relying on Hydraulic Brake Systems Since Time Immemorial
Braking systems have stuck to the same playbook for a very long time. Step on the pedal, hydraulic fluid travels through lines, pressure builds, and the calipers bite down on the rotors. It doesn’t matter if you’re driving a city hatchback, a big SUV, or a supercar – the basics haven’t really changed.
Braking tech has definitely moved forward – drums gave way to discs, ABS and brake force distribution arrived, and now we have regenerative braking and stability systems. But underneath all that, cars still depend on hydraulics to actually bring things to a halt.
That could finally be changing. Brembo just confirmed that its Sensify intelligent braking system is now in large-scale production. It’s one of the strongest signals yet that fully by-wire brakes are about to go mainstream.
A Brake System Without Hydraulic Fluid
Brembo says Sensify uses a fluid-free setup, ditching the usual hydraulic circuits and central actuators. Instead, each wheel gets its own electronic brain, so braking force is managed by software, not just hardware.
Put simply, pressing the brake pedal doesn’t push fluid through lines anymore. Instead, your input is read electronically and each wheel gets its own dose of braking force.
That means much finer control. Brembo claims the system can constantly adjust braking force based on road conditions, how the car is moving, and how much grip you have.
Brembo also sees Sensify as a big step toward software-defined cars. New EVs and next-gen vehicles are built around central software, where updates and even driving feel can change with a download. Sensify fits right in, especially for advanced driver aids and future self-driving tech.
Interestingly, Brembo said that Sensify will be standard on every car in this unnamed production run. So this isn’t just a one-off supercar experiment – we’re talking real volume, with contracts for hundreds of thousands of units each year already in place.
Brembo
So Which Automaker Is Using It?
That’s the big question. Brembo just calls the customer a “leading global vehicle manufacturer” and won’t say which one. Some brands have played with steer-by-wire and brake-by-wire in concept cars, especially among premium EVs. But rolling out a fully fluid-free brake system in mass production is a much bigger leap, especially since brakes are so crucial for safety and driver trust.
This could be one of those changes that quietly reshapes the industry over the next decade. Most drivers won’t notice if their car uses hydraulics or electronics to stop – just like nobody thinks about throttle cables or old-school handbrakes anymore. But underneath, it’s another step toward cars becoming software-driven machines instead of purely mechanical ones.
If Sensify really works as smoothly as Brembo says, old-school hydraulic brakes might soon start to feel outdated.

This Rocket-Boosted EV Claims 0–62 in 0.9 Seconds
https://www.autoblog.com/news/this-rocket-boosted-ev-claims-0-62-in-0-9-seconds
Next year will mark the 10th anniversary of the second-generation Tesla Roadster’s reveal in prototype form, and there’s still no sign of a production model yet.
The new Tesla Roadster has been delayed at least eight times since its initial unveiling in 2017, with the latest estimates suggesting a production start in 2027 or 2028. Given that time frame, there’s a high chance a surprise Chinese electric supercar equipped with rocket boosters will beat the Roadster—which should offer an optional SpaceX package featuring 10 cold-gas thrusters—to market.
We’re talking about the Nebula Next 01 Jet Edition, a bonkers electric four-door supercar project coming from the most unlikely of manufacturers—Chinese robot vacuum maker Dreame Technology (which also makes a bunch of other smart home appliances).
The Rocket-Boosted Electric Supercar That Came Out of Nowhere
Unveiled yesterday at the Dreame Next event in San Francisco, the Nebula Next 01 Jet Edition is a rocket-powered electric vehicle featuring a custom-built dual solid-fuel rocket booster system that gives it otherworldly performance—at least on paper.
Dreame Technology claims a neck-snapping 0-62 mph time of 0.9 seconds, which is unprecedented for a production vehicle. Not even the world’s quickest EV, the 2,200-hp Ford Mustang Cobra Jet 2200, can come close, as the electric dragster goes from 0 to 60 mph in 1.66 seconds.
Dreame says in a press release that the Nebula Next 01 Jet Edition’s rocket booster system responds in 150 milliseconds and generates a peak thrust of 100 kN—the equivalent of 22,480 pounds pushing down due to gravity.
No other powertrain or performance specs were disclosed, but Dreame did say the vehicle uses a CTP 4.0 (cell-to-pack) battery integration technology, which removes the traditional crossbeams and longitudinal beams from the battery pack to free up vertical space in the chassis. The company also said the car includes an ultra-high-definition DHX1 LiDAR unit for advanced driving assist features.
Vaporware or the Real Deal?
The Jet Edition appears to be based on the Dreame Nebula 1 electric supercar concept that debuted earlier this year at CES. That vehicle allegedly has a total of 1,876 horsepower from four electric motors and is capable of sprinting from 0 to 62 mph in 1.8 seconds.
Before dismissing the Nebula as vaporware, Dreame claims it has been working on its first car project for more than a decade, with the Nebula Next 01 Jet Edition pitched as a statement of its engineering. Dreame says that its decision to build vehicles “came only after the company had accumulated sufficient depth in technology, organization, capital, and global capability.”
So, what’s next? Last year, Dreame announced plans to build a factory outside Berlin, Germany, not far from Tesla’s Gigafactory Berlin; it hasn’t provided an update on the status of the plant project since. The company says it aims to start production of the Nebula Next 01 Jet Edition there in 2027, which is an insane timeline until you realize Chinese companies operate at a completely different speed than their western counterparts.
The Autopian sent an engineer at the reveal of the Nebula Next 01 Jet Edition concept and he wasn’t very impressed, noting that the two rockets at the rear have no gaps around them and “everything has been blocked by plastic covers.” Plus, the vehicle has no air inlets and outlets, and the grilles are decorative and blocked off. His conclusion was that those aren’t actual rockets, they’re just made to look like the real thing.
Of course, there’s also the possibility that the vehicle is just a design buck showcased for illustration purposes only, and a functional prototype exists somewhere. We’ll see if that’s the case if we ever hear about this rocked-powered EV supercar again.
