It’s simple to imagine that Robert Woo was outlined by the accident that took away his capability to stroll.
Actually, the day of his accident—14 December 2007—was a turning level. Woo, an architect engaged on the brand new Goldman Sachs headquarters in New York Metropolis, hadn’t attended his firm’s vacation celebration the evening earlier than, and that morning he was the one one within the trailer that served because the construction-site workplace. He was bent over his laptop computer when, 30 flooring above, a crane’s nylon sling gave way, sending about 6 tonnes of metal plummeting towards the trailer. The roof collapsed, folding Woo in half and smashing his face into his laptop computer, which smashed by way of his desk.
“I used to be acutely aware all through the entire ordeal,” Woo remembers. “It was an out-of-body expertise. I might hear myself screaming in ache. I might hear the voices of the rescue staff. I heard one firefighter say, ‘Don’t fear, we’re attending to you.’” The rescue staff hauled him out of the rubble and received him to the emergency room in 18 minutes flat; with one lung crushed and the opposite punctured, he wouldn’t have lasted for much longer. In these frantic early moments, a physician informed him that he is likely to be paralyzed from the neck down for the remainder of his life. He remembers asking the medical doctors to let him die.
Woo merely couldn’t think about how a paralyzed model of himself might proceed dwelling his life. Then 39 years previous, he labored lengthy hours and jetted all over the world to oversee the development of skyscrapers. Extra necessary, he had two younger boys, ages 6 months and a pair of years. “I couldn’t see having a life whereas being paralyzed from the neck down, not having the ability to train my boys find out how to play ball,” he recollects. “What sort of life would that be?”

However in a Manhattan showroom final Might, Woo confirmed that he’s not outlined by that accident, which left him paralyzed from the chest down, however with using his arms. As a substitute, he has outlined himself by how he has responded to his harm, and the brand new life he constructed after it.
Within the showroom, Woo transferred himself from his wheelchair to a 80-kilogram (176-pound) exoskeleton swimsuit. After strapping himself in, he manipulated a joystick in his left hand to rise from a chair after which proceeded to stroll throughout the room on robotic legs. Woo’s steps had been brief however clean, and he clanked as he walked.
This exoskeleton, from the French firm Wandercraft, is likely one of the first to let the person stroll with out arm braces or crutches, which most different fashions require to stabilize the person’s higher physique. The battery-powered exoskeleton took care of each propulsion and steadiness; Woo simply needed to steer. The cumbersome equipment had a backplate that prolonged above Woo’s head, a big padded collar, armrests, motorized legs, and footplates. Strolling throughout the room, he gave the impression to be half man, half machine. On the opposite aspect of the showroom’s plate-glass window, on Park Avenue, a child strolling by along with his household got here to a lifeless halt on the sidewalk, staring with awe on the cyborg inside.

The amazement on the boy’s face was harking back to Woo’s younger sons’ response once they noticed a photograph of Woo attempting out an early exoskeleton, again in 2011. “Their first remark was, ‘Oh, Daddy’s in an Iron Man swimsuit,’” he remembers. Then they requested, “When are you going to begin flying?” To which Woo replied, “Nicely, I’ve received to discover ways to stroll first.”
The title of exoskeleton superhero fits Woo. He’s as soft-spoken and mild-mannered as Clark Kent, with a smile that lights up his face. But the power beneath is plain; he has constructed a brand new life out of sheer dedication.
For 15 years, he’s been a check pilot, early adopter, and clinical-study topic for probably the most distinguished exoskeletons underneath growth all over the world. He positioned the primary order for an exoskeleton that was accepted for residence use, and he discovered what it was wish to be Iron Man round the home. All through all of it, he has given the businesses detailed suggestions drawn from each his architectural design expertise and his user experience. He has formed the expertise from within it.
Saikat Pal, a researcher on the New Jersey Institute of Expertise, in Newark, met Woo throughout medical trials for Wandercraft’s first mannequin. Like so many others within the discipline, Pal shortly acknowledged that Woo introduced rather a lot to the desk. “He’s a super-mega person of exoskeletons: very enthusiastic, very athletic,” Pal says. “He’s the proper topic.”
By pushing the expertise ahead, Woo has paved the way in which for 1000’s of individuals with spinal twine accidents in addition to different types of paralysis, who are actually benefiting from exoskeletons in rehab clinics and of their houses. “Our bionics program at Mount Sinai began with Robert Woo,” says Angela Riccobono, the director of rehabilitation neuropsychology at Mount Sinai Hospital, in New York Metropolis, the place Woo grew to become an outpatient after his accident. “We now have a plaque that dedicates our bionics program to him.”

It’s a becoming tribute. Woo’s post-accident life has been marked by victories, frustrations, deep love, and one devastating loss, and but he has continued to commit himself to bionics. And whereas his imaginative and prescient for exoskeletons hasn’t modified, expertise has reshaped what he expects from them in his lifetime.
Lengthy earlier than Woo ever stood up in a robotic swimsuit, he had developed the habits of thoughts that may later make him an unusually perceptive check pilot.
Woo has all the time been a builder, a tinkerer, a fixer. Rising up within the suburbs of Toronto, he put collectively mannequin kits of battleships and airplanes with out trying on the directions. “I simply put issues collectively the way in which I believed it might work out,” he says. He skilled as an architect and in 2000 joined the Toronto-based agency Adamson Associates Architects, a job that quickly had him touring to Europe and Asia to work on company high-rises.
Adamson focuses on taking the beautiful designs of visionary architects and turning them into sensible buildings with elevators and loos. “A lot of the design architects don’t actually have a clue about find out how to construct buildings,” Woo says. He favored fixing these issues; he favored reconciling stunning designs with the cussed actuality of development. That expertise for understanding a construction from the within and recognizing the issues would show important later.
After his accident, Woo had two main surgical procedures to stabilize his crushed backbone, which required surgeons to chop by way of muscular tissues and nerves that linked to his arms. For 2 months, he couldn’t really feel or transfer his arms; there was an opportunity he by no means would once more. Solely when sensation started creeping again into his fingertips did he permit himself to think about a distinct future. If he wasn’t paralyzed from the neck down, he thought, possibly extra of his physique might be introduced again on-line. “My focus was to stroll once more,” he says.
Woo was discharged in March 2008 and went again to his New York Metropolis condominium. He was nonetheless bedridden and required around-the-clock care. He doesn’t very like to speak about this subsequent half: By Might, his then-wife had moved again to Canada and filed for divorce, asking for full custody of their two youngsters. Woo remembers her saying, “I can’t take care of three infants, and one in every of them for all times.”
It was a darkish time. Riccobono of Mount Sinai, who met Woo shortly after he grew to become an outpatient there in 2008, recollects the despondent look on his face the primary time they talked. “I wasn’t positive that he wasn’t going to take his life, to be trustworthy,” she says. “He felt like he had nothing to stay for.”
Angela Riccobono of Mount Sinai Hospital (left) credit Woo with jump-starting the hospital’s bionics program; a plaque within the division of rehabilitation drugs acknowledges his position.
But Woo harbors no animosity towards his ex-wife. “If we hadn’t separated and gone by way of the custody listening to, I don’t suppose I might have gotten this far,” he says. To win partial custody of his youngsters, Woo needed to turn into impartial. He needed to get off narcotic ache drugs, regain power, and discover ways to navigate life in a wheelchair. He needed to present that he now not wanted fixed nursing, and that he might handle each himself and his boys.
There have been milestones: studying find out how to get again into his wheelchair after a fall, studying to drive a automobile with hand controls, studying to handle his physique because it was, not because it had been. The largest change got here when he reconnected along with his highschool sweetheart, a vivacious girl named Vivian Springer. She was then dividing her time between Toronto and New York Metropolis, and she or he had a son who was nearly the identical age as Woo’s two boys. Springer had labored in a nursing residence and knew find out how to change the sheets with out getting him off the bed; she was presently working in human sources and knew find out how to take care of insurance coverage firms. “You wouldn’t consider how a lot stress it lifted off of me,” Woo says. Over time, they grew to become a household.

As soon as Woo had that basis in place, Riccobono witnessed a profound change. “He went from specializing in ‘what I can’t do anymore’ to ‘What’s nonetheless attainable? What can I do with what I’ve?’” At Mount Sinai, Woo remembers asking his physician Kristjan Ragnarsson, who was then chairman of the division of rehabilitation drugs, if he would ever stroll once more. “His response was, ‘Sure, you possibly can stroll once more,’” Woo remembers, “‘however not the way in which you used to stroll.’”
First Steps in an Exoskeleton
As quickly as he had regained use of his fingers, Woo had began googling, searching for something that would get him again on his ft. He tried rehab gear just like the Lokomat, which used a harness suspended above a treadmill to allow customers to stroll. However on the time, it required three bodily therapists: one to maneuver every leg and one to regulate the machine. It was a far cry from the impartial strides he dreamed of.
A number of years in, he discovered about two firms that had constructed one thing radically totally different: exoskeleton fits for individuals with spinal twine accidents. These prototypes had motors on the knees and the hips to maneuver the legs, with the person stabilizing their higher physique with arm braces. Woo desperately wished to attempt one, though the expertise was nonetheless experimental and much from regulatory approval. So he took the concept to Ragnarsson, asking if Mount Sinai might deliver an exoskeleton into its rehab clinic for a check drive. Ragnarsson, who’s now retired, remembers the request nicely. “He definitely gave us the kick within the behind to get going with the expertise,” he says.

Ragnarsson had seen many years of failed makes an attempt to get paraplegics upright, together with “inflatable clothes fabricated from the identical materials the astronauts used once they went to the moon,” he says. All these units had proved too tiring for the person; in distinction, the battery-powered exoskeletons promised to do a lot of the work. And he knew one of many founders of Ekso Bionics, a Berkeley, Calif.–primarily based firm that had constructed exoskeletons for the navy. In 2011, Ekso brought its new clinical prototype to Mount Sinai.
The day got here for Woo’s first stroll. “I used to be excited, and I used to be additionally scared, as a result of I hadn’t stood up for nearly 5 years,” he remembers. “Standing up for the primary time was like floating, as a result of I couldn’t really feel my ft.” In that first Ekso mannequin, Woo didn’t management when he stepped ahead; as an alternative, he shifted his weight in preparation, after which a bodily therapist used a distant management to set off the step. Woo walked slowly throughout the room, utilizing a walker to stabilize his higher physique, his steps a symphony of clunks and creaks and whirs. He discovered it mentally and bodily exhausting, however the effort felt like progress.

Riccobono was there for these first steps, with tears working down her face. “I remembered how he seemed the day I first met him, so defeated,” she says. “To see him rise from the chair, to see him rise to a standing place, to see how tall he was, to see him take these first steps—it was stunning.” Ragnarsson noticed clear advantages to the expertise. “Any kind of strolling is sweet physiologically,” he says. “And it’s an incredible increase psychologically to face up and look somebody within the eye.” Woo remembers hugging his accomplice, Springer, and for the primary time not worrying about working over her toes along with his wheelchair. I first met Woo just a few days later, throughout his third session with the Ekso at Mount Sinai.

Later that very same 12 months, at a Division of Veterans Affairs (VA) hospital within the Bronx, Woo received to attempt a prototype of the world’s different main exoskeleton: the ReWalk, from the Israeli firm of the identical identify (since renamed Lifeward). VA researchers, led by Ann Spungen, had been eager to find out if exoskeleton use had actual medical worth for veterans with spinal twine accidents. Woo was a part of that clinical trial, for which he had greater than 70 strolling classes, and he’s since been in lots of others. However he remembers the primary VA trial with probably the most gratitude. “Dr. Spungen’s first exoskeleton medical trial actually turned issues round for me,” he says.
Over the course of the trial’s 9 intense months, Woo says he noticed noticeable enhancements to many aspects of his well being. “By the top of the trial, I eradicated about three-quarters of my remedy consumption,” he says, together with narcotic ache tablets and medicine for muscle spasms. He grew fitter, with less body fat, extra muscle mass, and decrease ldl cholesterol. His circulation improved, he says, inflicting scrapes and cuts to heal extra shortly, and his digestion improved too. The outcomes Woo skilled have typically been borne out in analysis research on the VA and elsewhere—exoskeletons aren’t simply good for the thoughts, they’re good for the physique.
Enhancing Exoskeletons From the Inside
In the course of the VA trial, Woo started to think about exoskeletons not as miraculous machines, however as works in progress.
Pierre Asselin (proper), a biomedical engineer, labored with Robert Woo throughout medical trials of exoskeletons. He says Woo was all the time pushing the bounds of the expertise. Robert Woo
Pierre Asselin, the biomedical engineer coordinating the VA’s research, watched members reply very in a different way to the gear. “These units aren’t the equal of strolling—you’re drained after strolling a mile,” he says. He notes that later fashions of each the Ekso and ReWalk enabled customers to provoke every step by way of software program that acknowledged once they shifted their weight. Asselin provides that the cognitive load is “like studying to drive a handbook transmission automobile, the place at first you’re actually struggling to coordinate the clutch and the brake.” Woo picked it up instantly, he remembers.

Woo grew to become a useful accomplice, Asselin says. “Once we first began with the units, there was no coaching handbook. We developed all of that by way of collaboration with Robert and different members.” Woo pushed the bounds of the expertise, Asselin says, whether or not it was seeing what number of steps he might tackle one battery cost or simulating a failure mode. “He’d say, ‘What occurs if I used to be to fall? What could be the method to getting up?’”
Woo approached the ReWalk the way in which he had approached buildings in his earlier life: He seemed contained in the construction and located the weak factors. An early mannequin left some customers with leg abrasions the place the straps rubbed—a small harm for most individuals, however a critical danger for somebody who can’t really feel a wound forming. Woo instructed higher padding and stronger belly helps to redistribute the load. He additionally hated the heavy backpack that carried the battery and pc, so one afternoon he grabbed an previous pack, reduce off the straps, and rebuilt it right into a compact hip-mounted pouch. Then he snapped photographs and despatched them to the corporate. The subsequent mannequin arrived with a fanny pack.

Typically his fixes had been extra formidable. One Ekso unit that he used at Mount Sinai saved shutting down after half-hour. Woo felt the hip motors and located them sizzling to the contact. “I mentioned, ‘Can I take away these? I’m going to make a extremely fast repair, okay? Give me a drill and I’ll put a few holes in it,” he recollects telling the therapists, proposing to create a DIY warmth sink. He wasn’t allowed to switch the prototype, however a 12 months later the corporate launched improved cooling across the hip motors. “There’s a Robert Woo design on this machine,” one therapist informed him.
Eythor Bender, who was then the CEO of Ekso, referred to as Woo to thank him for his suggestions and invite him to spend per week at Ekso’s headquarters. “There was no lack of engineering energy in that constructing,” says Bender. “However typically while you work with engineers, they overlook necessary issues.” Bender says Woo introduced each design expertise and lived expertise to his weeklong residency. “He informed the engineers, ‘Guys, this needs to be one thing that individuals really wish to put on.’”
Ekso Bionics CEO Eythor Bender and Mount Sinai doctor Kristjan Ragnarsson had been each available for Woo’s early trials of the Ekso machine. Ragnarsson says he noticed bodily and psychological advantages of exoskeleton use. Robert Woo
The longer Woo examined, the additional forward he began pondering. With motors solely on the hips and knees, each exoskeleton nonetheless required crutches. Add powered ankles, he informed the Ekso and ReWalk groups, and the fits might steadiness themselves, releasing the person’s fingers. However Woo was forward of his time. “They mentioned they weren’t going to do this. They weren’t going to alter their complete platform,” he remembers. Years later, although, hands-free exoskeletons like these from Wandercraft would emerge constructed round precisely that precept.
When the Exoskeleton Got here Residence
By the mid-2010s, Woo had pushed the expertise so far as he might in clinics. What he wished now was to make use of an exoskeleton at residence.
That milestone got here after ReWalk’s exoskeleton grew to become the primary to win FDA approval for home use in 2014. ReWalk engineers nonetheless bear in mind Woo’s assistance on the ultimate exams for that personal-use mannequin. It was the top of Might in 2015, recollects David Hexner, the corporate’s vp of analysis and growth. “He mentioned, ‘Guys, that is nice. I’m going to purchase it.’”
Woo was the primary buyer to purchase an exoskeleton to deliver residence, paying US $80,000 out of pocket. His insurance coverage wouldn’t cowl the price, however he was capable of make the acquisition partially due to a authorized settlement after his accident. The house-use mannequin got here with a requirement that the person have at the very least one companion who was totally skilled in working the machine. In Woo’s case, that meant that Springer discovered to swimsuit him up, realign his steadiness, and assist him if he fell.
On supply day, two SUVs drove as much as a lodge down the road from Woo’s condominium within the Toronto space. The technicians hauled two enormous containers right into a lodge room and assembled his private exoskeleton. They took Woo’s measurements, made changes, checked the software program. This newest model might be managed by both weight shifting or tapping instructions on a smartwatch, and Woo had the app prepared. He examined out every little thing within the lodge room, signed off, after which the technicians drove his robotic legs to his residence.
That was the beginning of his golden interval with the ReWalk—just like the joy many individuals expertise with a brand new piece of train gear. “I used it day-after-day for just a few hours, after which I began logging what number of steps I’d finished,” Woo says. “My final depend was in all probability simply barely over one million steps,” he says, with half of these steps taken in his residence unit and half in coaching applications and medical trials.
The ReWalk was the primary exoskeleton out there to be used exterior the clinic. Robert Woo’s ReWalk arrived in two massive containers. ReWalk engineers assembled it in a lodge room, and Woo tried it out within the hallway earlier than taking it residence. Robert Woo
Tristan, Woo’s eldest son, remembers doing laps along with his dad within the condominium’s underground parking storage whereas his dad was coaching for a 5-kilometer race in New York Metropolis. Tristan admits that he had beforehand been embarrassed about his dad, however coaching for the race shifted one thing for him. “I used to be so used to not wanting to inform those that my dad was in a wheelchair, however then I shared his ardour for the coaching,” he says. “When individuals would come as much as us, I’d inform them about it.”
The ReWalk might flip strange moments into small engineering tasks. On weekends, Woo would take his boys to the golf course behind their condominium and produce a baseball. He had rigged two holsters to the edges of the swimsuit so he might stash a crutch and stand on three factors (two legs and one arm) whereas he pitched or caught. Throw, change crutches, catch. On the day of his accident, he by no means thought such a scene could be attainable. However with the exoskeleton, it grew to become simply one other design drawback to unravel. “It’s just a little extra work. It’s not excellent,” he says. “However in the long run, you continue to get to do what you wish to do—which is play ball together with your sons.”
Tristan, now a school scholar, says he didn’t understand on the time how laborious his dad labored to make these mundane actions attainable. “Reflecting on it now,” he says, “he has formed nearly each component of my life, and he positively is my hero.”
However even throughout that golden stretch, the ReWalk had a approach of asserting its limits. Sometimes it might freeze mid-stride and require a reboot—a small technical hiccup in concept, however a significant issue when there’s an individual strapped inside. As soon as, when he was strolling on his personal within the parking storage (with out his mandated companion), the swimsuit glitched and went into “swish collapse” mode, decreasing him to a seated place on the bottom. Woo needed to ask safety to deliver his wheelchair and a dolly.
He had imagined the exoskeleton could be most helpful within the kitchen. Woo likes to cook dinner, and he had pictured himself standing on the range, trying down into pots, and transferring simply between counter and sink. The fact, he came upon, was extra difficult. “It’s really very time-consuming and troublesome” to cook dinner in an exoskeleton, he says.
Making ready a meal meant first rolling by way of the kitchen in his wheelchair to assemble each ingredient and utensil, then transferring himself into the ReWalk and transferring himself into place on the counter, stopping at simply the appropriate second. “That’s once I fell as soon as,” Woo says. “I collided with the counter after which misplaced my steadiness and fell backward.” If all went nicely, he’d lean both on one crutch or the counter to maintain his steadiness whereas he labored. But when he’d forgotten to seize the vinegar from the cupboard, he’d have to enter stroll mode, crutch over to it, and determine find out how to carry the bottle again to his workstation.
Sitting unused in Robert Woo’s residence, his ReWalk exoskeleton displays each the promise and the bounds of early units. Robert Woo
Steadily, he stopped attempting. The swimsuit, which he’d as soon as worn day-after-day, spent extra time sitting idle within the hallway; like so many deserted treadmills and stationary bikes, it gathered mud. A part of the explanation was the exoskeleton’s sensible limitations, however a part of it was a surprising growth: In 2024, Vivian was identified with an aggressive type of breast most cancers. She died in November of that 12 months, on the age of 54.
Woo was scheduled to start a brand new spherical of medical trials for the Wandercraft home-use exoskeleton that month. Within the aftermath of Vivian’s demise, he postponed his classes and questioned whether or not he would ever return. “On the time, I believed, ‘What’s the purpose?’” he remembers.
He did return, although. “He simply rolled up, proper into my workplace,” says Mount Sinai’s Riccobono. “He nonetheless had Vivian’s field of ashes on his lap. That’s how recent it was.” Woo introduced the field into a gathering of spinal twine harm sufferers and shared the story of dropping the love of his life. And he informed them that he heard his spouse’s voice in his head day-after-day, telling him to get again to work. As soon as once more, he was determining find out how to transfer ahead with what he had.
How Shut Are We to On a regular basis Exoskeletons?
Within the Wandercraft showroom final Might, Woo steered towards the door to the road, technicians flanking him like spotters. The slope right down to the sidewalk was barely an inch excessive, however everybody tensed. He shifted his weight and took a step ahead. The swimsuit halted robotically. He tried once more—step, cease; step, cease—because the swimsuit saved detecting the slight decline and a security function kicked in. The Wandercraft isn’t but rated for slopes of greater than 2 p.c, and even the mild pitch of Park Avenue was sufficient to set off its safeguards. When he lastly reached the sidewalk, Woo broke into a smile. A person within the again seat of a stopped Uber leaned out his window, filming.
Throughout testing of the Wandercraft exoskeleton, straps prompted an abrasion on Robert Woo’s leg, which he documented as a part of his suggestions to the corporate. Robert Woo
Woo had not too long ago accomplished seven classes with the Wandercraft on the VA hospital and had been impressed total. However on the showroom, he rolled up his pants leg to disclose an abrasion on his shin, the results of a strap that had worn away a patch of pores and skin throughout an extended strolling session. He would later ship Wandercraft a nine-page evaluation with photographs and a expertise want checklist, asking the corporate to work on issues like padding, variable strolling speeds, and deeper squats.
Wandercraft’s engineers relish that type of person suggestions, says CEO Matthieu Masselin. Exoskeletons are a much more troublesome engineering drawback than humanoid robots, he explains. “You principally have two methods of equal significance. You understand in regards to the robotic—it’s totally quantified and measured. However you don’t know what the particular person is doing, and the way the particular person is transferring throughout the machine.”
Since Woo started testing exoskeletons 15 years in the past, each the expertise and the market have made strides. ReWalk and Ekso gained FDA clearance for medical use within the 2010s, and each now promote home-use variations. The businesses have offered 1000’s of exoskeletons to rehab clinics and private customers, and so they see room for development; in the USA alone, about 300,000 people live with spinal cord injuries, and thousands and thousands extra have mobility impairments from stroke, a number of sclerosis, or different situations. The VA started supplying units to eligible veterans in 2015, and Medicare not too long ago established a system for reimbursement, a transfer that personal insurers are starting to comply with. What was as soon as experimental is slowly changing into established.
Researchers who check the units say the expertise nonetheless has important limits. Pal, of the New Jersey Institute of Expertise, mentions battery life, dexterity, and reliability as ongoing challenges. However, he says with amusing, “Our our bodies have advanced over many thousands and thousands of years—these machines will want a bit extra time.” Pal hopes the businesses will preserve pushing the technological frontier. “My lifetime objective is to see the day when somebody like Robert Woo can get up within the morning, put this machine on, after which stay an strange life.”
For Woo, the actual query in regards to the self-balancing Wandercraft was: Might he cook dinner with it? Within the VA hospital’s residence mockup, he tried it out within the kitchen, stepping sideways to retrieve objects from cupboards and squatting to seize one thing from the fridge’s decrease shelf. For the primary time in years, he might work at a counter with out leaning on crutches. “The self-standing exoskeleton modifications every little thing,” he says. He imagines a person putting a Thanksgiving turkey on a tray hooked up to the swimsuit and strolling it into the eating room.
Again within the showroom, Woo finishes the demo and brings the swimsuit to a seated place earlier than transferring again to his wheelchair. After so a few years of testing prototypes, he’s now sensible in regards to the expertise’s timeline. A very all-day exoskeleton—the sort you reside in, the sort that replaces a wheelchair—could also be a decade or extra away. “It will not be for me,” he says. However that’s now not the purpose. He’s desirous about younger people who find themselves newly injured, who’re mendacity in hospital beds and attempting to think about how their lives can proceed. “This can give them hope.”
