amara Mena was 19 years old when she dismissed all hope of
ever walking again. Mena was living in San Diego and working
toward a degree in hotel management when she and her boyfriend Patrick decided to hit the clubs in Rosarito Beach, just
across the Mexican border. Since they didn’t want to risk drinking and driving, they took a cab. They never made it to Mexico. T
About 2 miles from their destination, their
vehicle slammed into a horse. The impact
launched the animal into the air; it landed on
top of the cab, crushed the roof to seat level, and
killed Patrick and the driver instantly. Mena was
paralyzed from the midchest down.
“I wanted to walk,” she says. Graced with
tawny hair, high cheekbones, and chocolate-brown eyes, Mena, now 25, is a picture of youthful vitality if you overlook the tracheotomy scar
where medics inserted a tube to oxygenate her
collapsed lungs after the accident. “I looked into
walking with braces, but they sucked the energy
right out of me. I met with a doctor about stem-cell treatments, but that was costly and there
was no guarantee. I gave up. I had to move on.”
Six years after that fateful night, in a nondescript warehouse in Berkeley, California, she
is moving on—using her own two legs. She
stands on the linoleum floor, supporting herself
with a pair of crutches, an expression of quiet
determination on her face. The lower two-thirds
of her body are enclosed in an aluminum frame
attached by Velcro straps to her ankles, calves,
thighs, hips, and chest. A physical therapist
stands behind her, one hand grasping a handle
on the contraption’s rear panel, the other holding a control panel. Each time the therapist
presses a button, small electrical motors at the
frame’s joints move in a motion that replicates
the action of corresponding muscles—one of
Mena’s hips swings ahead, the associated knee
rises, the foot lifts and then falls to the floor,
and she takes a precious step forward.
Mena is a test pilot for Ekso Bionics, a front-
runner in robotic exoskeleton technology, which
can replace or augment human capabilities. Led
by Icelandic CEO Eythor Bender, the company
has licensed its technology to Lockheed Martin
for military use and sold its initial medical prod-
uct, the Ekso, to rehabilitation centers through-
out the U.S. Bender says the medical market is
just the beginning. He envisions robotic frames
for industrial workers, like miners, dockers, and
construction workers. He imagines that each of
pricey gewgaw. He will need to outdistance com-
petitors, some of whom already have products
on the market. Finally, he must persuade the
FDA and the insurance industry that paralyzed
people need to walk, a proposition that’s con-
troversial even among paraplegics.
EXOSKELETONS, SAYS EKSO BIONICS CEO BENDER,
WILL BE “THE JEANS OF THE FUTURE,”
STREAMLINED ENOUGH TO WEAR IN ECONOMY CLASS.
us will want an exoskeleton: “the REI Ekso,”
recreational outerwear that confers superhuman
strength and endurance.
“We’re starting with soldiers and paralyzed
people because their needs are great and the opportunity for funding is better,” Bender says. “But
you can imagine exoskeletons for workers using
tools too heavy to hold for more than a few minutes. And a consumer version for people who
want to run a marathon or climb Mount Kilimanjaro.” Exoskeletons, he dreams, will be “the jeans
of the future”—practical, fashionable, and streamlined enough to wear in economy class.
First, though, he must get past obstacles that
have derailed many a medical-device company.
He must convince rehabilitation therapists and
wheelchair users that the Ekso is more than a
eye and hug someone while you’re standing up.
I had forgotten what that felt like. Once you re-
member, it’s hard to go back to a wheelchair.”
Ekso Bionics’ staff has ballooned from 23 to 68
in the past year, and its Berkeley facility is fit to
burst. Past the cramped reception area (which
doubles as a customer-service bullpen), it’s
Santa’s robotics workshop. The 12,000-square-
foot floor is a labyrinth of workbenches, storage
bins, and whiteboards covered with electrical
diagrams. A yellow gantry—basically a 35-foot
girder on trestles—cuts across the floor to protect
test pilots like Mena against falling.
A fully assembled Ekso hangs on a rack next
to one of the benches, its legs pumping repetitively in test mode. Even without an upper body,
