Mechanical Miracles [Photo Gallery]

When UC Berkley Professor Homayoon Kazerooni arrived from Iran to America in the late 1970s, he had just a few hundred bucks in his pocket. He also had big dreams.

Those dreams have translated into an invention that allowed people to walk again after paralyzing accidents and illnesses. Called the eLEGS, the device was a medical exoskeleton that restores the ability of paraplegics, MS patients and stroke victims to walk.

The technology he helped pioneer now is entering the workplace, and eventually could help reduce musculoskeletal injuries for workers.
