Seiji Uchida, paralyzed from the neck down as a result of a 1983 traffic accident, will take a cable car to a point close to the summit of Breithorn, a 1,164-metre Swiss peak. Alpine mountaineer Ken Noguchi will carry him to the top, with the assistance of the HAL-5 exoskeleton.

HAL provides enough additional strength to lift an additional eighty kilograms of weight. The trek is planned for this summer.

Robotic exoskeletons have played a part in science fiction stories for decades. In his 1968 novel A Specter is Haunting Texas, science fiction writer Fritz Leiber describes specialized exoskeletons used to help human beings who grew up under microgravity conditions survive on the Earth's surface:

This truly magnificient, romantically handsome, rather lean man was standing on two corrugated-soled titanium footplates. From the outer edge of each rose a narrow titanium T-beam that followed the line of his leg, with a joint (locked now) at the knee, up to another joint with a titanium pelvic girdle and shallow belly support. From the back of this girdle a T-spine rose to support a shoulder yoke and rib cage, all of the same metal. The rib cage was artistically slotted to save weight, so that curving strips followed the line of each of his very prominent ribs.

...The motors were controlled by myoelectric impulses from his ghost muscles transmitted by sensitive pickups buried in the foam-padded bands.

Note that the 1968 fictional exoskeleton used myoelectric sensors in the bands holding the user to actuate movement, just like the 2006 real-life version.

Update: It turns out that Uchida was partly successful in making the climb:

But Uchida, who rode piggyback on a friend who was aided by a motorized exoskeleton, said he viewed getting to within 500 yards of the mountaintop as a triumph.

"Today ... I had the same feeling as when I saw the pictures of the Breithorn for the first time: I was overwhelmed," Uchida said after his return to a base station on the Klein Matterhorn.

Uchida said through an interpreter that he was grateful he "had the chance to realize my dreams of climbing it, thanks to the suit."

They covered about two miles before having to turn back due to time considerations. End update.
