Industrial exoskeletons help workers do more with less strain

NEWYou can now listen to Fox News articles!

If you have ever spent a full day lifting, drilling overhead, or bending over a conveyor belt, you know how quickly fatigue sets in. That is exactly where industrial exoskeletons come in. 

These wearable systems strap onto the body and help carry the load. Instead of your muscles doing all the work, the device shares it. As a result, workers feel less strain and can stay productive longer. This tech is already showing up on real job sites across the country.

What are industrial exoskeletons?

Industrial exoskeletons are wearable mechanical systems designed to support your body during physical tasks. They do not replace workers. They help workers perform demanding jobs with less physical stress. There are three main types, and each works differently depending on the job.

Passive exoskeletons: simple support that works

Passive systems do not use motors or batteries. Instead, they rely on springs or mechanical structures to redistribute weight.

A strong real-world example is the Hilti EXO-O1. This shoulder harness shifts the weight of your arms to your hips using spring-loaded supports. Testing shows it can reduce shoulder muscle load by up to 47% during overhead work. Many workers say tools feel almost weightless by the end of the day.

Another example is the Laevo FLEX. This passive system uses spring-based assistance to support the lower back during bending and lifting. It is designed for dynamic movement, allowing workers to walk freely and lift without needing to switch the system on or off.

Laevo FLEX also offers adjustable support and is built for long wear across different environments, including outdoor use. Like other passive systems, it helps reduce strain on the lower back during repetitive tasks without adding motors or batteries.

These systems are relatively lightweight, typically between about 4.4 and 8.8 pounds. However, support remains constant during use, so it cannot adapt automatically to different tasks in real time.

Powered exoskeletons: high-tech strength on demand

Powered exoskeletons use motors, sensors, and onboard processors to actively assist movement. An example is the German Bionic Exia. This battery-powered back exoskeleton is designed for warehouse and logistics work, where employees lift and move items throughout the day. It actively supports the lower back during lifts, helping reduce strain and fatigue over time.

These systems track your motion using sensors and respond almost instantly. Many can detect lifting movements in real time and provide support as you move, so the assistance feels natural instead of delayed.

Powered exoskeletons can significantly reduce the effort required for repetitive lifting tasks, especially in high-volume environments.

However, there are trade-offs. Some powered systems are heavier and can weigh over 40 pounds, depending on the design. They are also far more expensive, often costing tens of thousands of dollars, so most companies introduce them through pilot programs.

Soft exosuits: flexible and lightweight

Soft exosuits use fabric, straps and tension systems instead of rigid frames. One example is the HeroWear Apex 2. This lightweight system weighs about three pounds and wraps around the shoulders and waist to assist with lifting movements.

In warehouse testing, soft back-support exosuits have been shown to improve productivity while reducing reported lower back discomfort for workers performing repetitive tasks.

These systems allow more natural movement than rigid exoskeletons. However, they provide less force, so they are best suited for repetitive tasks rather than heavy lifting.

Where exoskeletons make the biggest impact

The biggest benefits show up in everyday tasks that put the most strain on your body.

Overhead work becomes manageable

Holding tools above your head all day strains your shoulders and neck. Systems like the Hilti EXO-O1 can reduce muscle load by up to about 47%, making tools feel much lighter.

Heavy lifting gets safer

Back-support systems like the Laevo FLEX shift part of the load away from the spine. Studies show muscle effort can drop by up to 30% during lifting.

Repetitive bending adds up less

Soft systems like the HeroWear Apex 2 help reduce fatigue during constant bending. Workers complete more tasks while feeling less strain by the end of a shift.

The trade-offs you should know

Exoskeletons offer real benefits, but they are not perfect. Fit is critical. If a device does not align properly with your body, it can cause discomfort or limit movement. Proper fitting and training are essential. Weight also matters. Even lightweight systems add extra load. Powered systems can weigh more than 40 pounds.

Cost remains a barrier for many companies. Passive systems may cost a few thousand dollars, while powered systems can cost tens of thousands. There is also a long-term consideration. Relying too heavily on assistance could reduce muscle engagement over time. Experts recommend using exoskeletons alongside proper ergonomics and regular movement.

What this means for you

If your job involves physical labor, this technology could change your daily experience. You may feel less sore at the end of a shift. You may reduce your risk of injury over time. You may even be able to work longer without the same level of fatigue. 

For employers, the benefits are clear. Fewer injuries, fewer missed workdays, and more consistent productivity. Adoption is still growing, so many workplaces are testing these systems before rolling them out more broadly.

Where can you buy industrial exoskeletons?

You might be wondering if you can order one of these like any other piece of gear. In most cases, you cannot. Most industrial exoskeletons are sold directly to companies, not individuals. Manufacturers typically work with employers through pilot programs or bulk orders. That means you will not usually find these on standard retail sites.

Some lighter systems, especially passive or soft exosuits, are easier to access. Even then, many brands still prefer to sell through business channels or approved partners.

If you are interested, start with the manufacturer’s website. Look for options like “request a demo” or “contact sales.” This is often the first step before any purchase. For now, access depends on where you work. As adoption grows, that could change. More companies are testing these systems, which may eventually make them easier to get.

More than a decade later, the team behind N++ is back with a multiplayer sequel

Published

More than a decade later, the team behind N++ is back with a multiplayer sequel

Back in 2015, the two-person studio Metanet released N++, a brutally hard 2D platformer that was a decade in the making, building off of previous releases dating back to the freeware Flash title N. At the time, cofounder Raigan Burns issued some famous last words: “We hope it’s not another 10 years before we come up with a game.” But now here we are, more than a decade later, and N is getting another sequel. And this time the focus is on multiplayer.

The new game is called, absurdly, N Plus Infinity Times Two. Whereas N++ was meant to be the ultimate single-player version of the N concept, this game is described as “the ultimate virtual couch party game with a low skill floor and no skill ceiling.” That means the same slick, acrobatic platforming action and gorgeous graphic design-inspired visuals, but now built around playing competitively or cooperatively with pals across a handful of different modes. It’s launching on the PS5, Xbox, Switch 2, and PC at some point in 2027.

The duo at Metanet was up to a few different things over the last 11 years. In addition to uprooting from Toronto to Montreal, they’ve been prototyping ideas for a few potentially bigger projects, and last year released a 10-year anniversary update for N++. But then, “We started getting the ‘let’s take another crack at it’ bug in 2022,” Burns tells The Verge.

The studio operates in an unusual way, at least compared to most of the game industry. Despite having two hits in N+ and N++, Metanet hasn’t grown or scaled up in any way. And the reason comes down to the way they make games: It simply takes a lot of time to find a game idea that’s worth pursuing as a commercial project. “We’ve resisted doing something that would compromise our ability to keep iterating and prototyping until something good shows up,” says Burns.

“It’s important to feel that magic,” cofounder Mare Sheppard adds. “That’s what’s compelling about making games. That’s when we know that we’re doing it in a way that’s right for us.” Burns has a clear analogy for how they work: “We like being in a band. That’s fun. Being in a lot of meetings and doing a lot of managing: not fun.” This philosophy seems especially prescient given the state of the games industry, where even the biggest hits operate in a way that’s clearly unsustainable.

“We like being in a band. That’s fun. Being in a lot of meetings and doing a lot of managing: not fun.”

In the case of N Plus Infinity Times Two — unfortunately I can’t think of a good way to shorten that title — the spark came in part from watching how younger players interact with games. Even when they’re playing solo, kids are typically still chatting with friends on their phones, essentially turning everything into a multiplayer experience. Burns and Sheppard wanted to find a way to marry that idea with the couch co-op experiences they grew up on, which led to revisiting the N concept but with a multiplayer spin.

The two describe making N++ as a grueling experience. If you think the game’s levels are hard, just imagine having to playtest them over and over. Part of the excitement about N Plus Infinity Times Two wasn’t just finding a spin on the formula that would be fun to play, but also to develop. “This one really feels like we’re having fun,” says Burns. “We’re really fluent in this one instrument. So now the fun challenge becomes playing new styles of music we’ve never played before, but with this thing we’re really comfortable with.”

As creative industries from games to Hollywood become increasingly homogenous, Burns also believes that there’s something important about doing work that’s distinct, even if it means revisiting a previous idea, like through the multiple versions of N. It’s similar to titles like Hades II and Silksong: indie-developed sequels that iterated a core concept, but with a fresh angle that made them more than a by-the-numbers follow-up. “Being yourself is more fun and exciting anyways,” Burns explains. “But I honestly think it’s more commercially viable to do something only you can do, because then you have no competition.”

As for what’s next after N Plus Infinity Times Two, the pair obviously aren’t revealing anything just yet. There are a few bigger 3D game ideas kicking around, but those would necessitate some of that scaling up that the studio has so far avoided. What they won’t close the door on, however, is coming back to the idea of N again at some point in the future.

“If we can do something that expresses something new, or lets us see things in a different way, or we get a different perspective on what this game is or how to play it, that’s exciting,” says Sheppard. “I think we no longer think this is definitively going to be the last one. We’ve abandoned that idea. It doesn’t have to be.”

Will a four-armed robot replace astronauts in space?

Will a four-armed robot replace astronauts in space?

NEWYou can now listen to Fox News articles!

Space changes the rules for almost everything, including how a robot should move. On Earth, legs help us stand, balance and walk across a room. In microgravity, those same legs lose much of their purpose.

That is why Orbit Robotics, an academic spinout from ETH Zurich, took a different approach with Helios. The robot was built with four arms so it can grip, brace and work inside a spacecraft. Two arms can hold on while the other two handle tools, cargo and equipment.

It is a smart design for a place where floating is easy and staying steady is the real challenge. Here is how Helios works and why it could change the way astronauts get help in orbit.

IS THIS SPACE CAPSULE HOW WE WILL LIVE AND WORK IN ORBIT IN THE FUTURE?

Why the Helios space robot has four arms

Helios uses two pairs of arms with different jobs. One pair can anchor the robot to interior surfaces. The other pair can handle tools, unload cargo, move equipment or perform other work inside a spacecraft.

That setup is important because stability and work need to happen at the same time in orbit. A floating robot cannot casually plant its feet, bend over and pick something up. It needs to hold on while it works.

That is where Helios makes sense. Two arms can keep it steady while the other two get the job done. In microgravity, legs become extra hardware unless they can grip, brace or manipulate objects. Helios skips that problem by turning the whole body into a tool for movement and work.

How this four-armed space robot works

Orbit Robotics says Helios uses a tendon-driven system. Instead of placing motors at every joint, the robot keeps many of those motors closer to the shoulders. Cables and pulleys then transmit force through the arms.

That design can reduce weight at the ends of the limbs. In space, heavy limbs can create awkward movement. A robot also needs control, especially when it is holding cargo or tools near expensive equipment.

Helios also uses a rolling-contact elbow joint. That may sound like a tiny detail. In orbit, it can make a big difference. A sudden jerk could destabilize the robot. It could also send whatever the robot is carrying drifting across a spacecraft. Smooth movement becomes a safety feature.

How IKARUS helped shape Helios

Before Helios, the team built an earlier robot platform called IKARUS. That project helped test ideas such as teleoperation, imitation learning and dual-arm manipulation. In other words, IKARUS gave the team a way to learn how a robot could move, copy tasks and handle objects in a space-like setting.

Those lessons helped shape Helios. That is important because space hardware rarely gets a second chance. A robot designed for orbit has to be reliable, compact and useful in cramped conditions. It also has to behave predictably around humans. Helios builds on that earlier work with a body that better fits the environment.

Why astronauts need robotic help in orbit

Orbit Robotics says its mission is to free astronauts, not replace them. That sounds reassuring. It also makes practical sense. Astronauts are highly trained people doing some of the most expensive labor imaginable. Yet a major chunk of crew time aboard the International Space Station goes toward maintenance.

Some estimates put maintenance at roughly 35% of crew time. At an estimated $140,000 per astronaut-hour, basic logistics can become shockingly expensive. That means sorting supplies, moving equipment or handling routine work can carry a huge price tag. Helios does not need to be a genius to help. It needs to move through narrow corridors, stay stable without gravity and manipulate objects with care. That is the point of the design.

What Helios could do in space

The first job for Helios appears focused on interior spacecraft work. That could include unloading cargo, helping manage supplies, moving gear and assisting with routine maintenance. Those jobs may sound boring. In orbit, boring tasks still take time, training and attention.

Over time, Orbit Robotics sees a broader role for robots like Helios. That could include satellite servicing. It could also include in-space construction as commercial stations and orbital habitats become more common.

If launch costs keep falling, more equipment will head into orbit. More hardware means more maintenance. More stations mean more logistics. That creates a clear opening for robots like Helios, built for space from the start.

Why robots may take on more space work

Human spaceflight still captures the imagination. It always has. However, the human body has serious limits in space. Astronauts can face radiation exposure, bone loss, vision problems and cognitive effects linked to fluid shifts in the brain.

Those risks grow during longer missions. Robots do not need air, food, sleep or radiation protection in the same way humans do. They can also take risks that would be unacceptable for astronauts.

That does not make astronauts obsolete overnight. Still, it changes the conversation. If machines can handle more work in orbit, humans may spend less time on routine tasks and more time on science. That could mean more attention on research tied to aging, cancer treatments, organ bioprinting and other experiments that benefit from microgravity.

Could space robots build the next space economy?

If commercial space stations grow, they will need constant care. Cargo will need to be sorted. Equipment will need to be moved. Structures may need inspection or repair. Satellites may need servicing. Future habitats may need robots that can assemble, maintain and adapt.

That is where a machine like Helios becomes more than a cool prototype. It could become part of the labor force that keeps space infrastructure running.

The big question is whether humans remain at the center of that work or move into a more selective role. We may still send astronauts into orbit, but their jobs could change dramatically.

Instead of doing every task by hand, they may supervise robots built for a place where the human body struggles.

What Helios could mean for future space robots

Engineers are starting to design machines for specific environments instead of forcing them into human-shaped bodies. That shift could affect more than space exploration.

Advertisement

On Earth, robots already work in warehouses, factories, hospitals and disaster zones. In each case, the best design may not look human. It may look strange, specialized and a little unsettling.

Helios shows why that can be a good thing. A robot built for its environment can work more efficiently. It can also take on risky jobs and help humans focus on work that needs judgment, creativity or science training.

For space, that could mean safer missions. It could also mean fewer astronauts spending precious hours on routine maintenance.

Kurt’s key takeaways

Helios stands out because it was built for the place it is meant to work. In orbit, walking offers very little help. Gripping, bracing and handling equipment become much more important. That is what makes the four-armed design so practical. It gives the robot a way to hold on while it works, which is exactly what astronauts need in microgravity. Orbit Robotics says Helios is meant to help astronauts, not replace them. Still, this robot raises a bigger question. As machines grow more capable, they could take on more of the risky and repetitive work beyond Earth. That could give astronauts more time for science, discovery and decisions that need human judgment. It could also change how we think about sending people into space in the first place.
