This $40,000 Robotic Exoskeleton Lets the Paralyzed Walk

Paralyzed from the waist down after a BMX accident, Steven Sanchez rolled into SuitX's Berkeley, California, office in a wheelchair. A half-hour later he was standing and walking thanks to the Phoenix--a robotic exoskeleton now available for around $40,000. The suit returns movement to wearers' hips and knees with small motors attached to standard orthotics. Wearers can control the movement of each leg and walk at up to 1.1 miles per hour by pushing buttons integrated into a pair of crutches. At 27 pounds, the Phoenix is among the lightest and cheapest medical exoskeletons.
