Exoskeleton Technology Helps Paraplegic Student Walk Again

Article features the Austin exoskeleton legs, lightweight battery powered mechanical braces that enable an individual with paraplegia to walk. Developed by scientists at the University of California, Berkeley, the braces are strapped to the user who carries the power supply in a small backpack. The motors in each joint are controlled by sensors, actuators, and computer chips to propel the body frame forward. The frame uses low power parts, making it cheaper and easier for home use, with one battery charge lasting 4 to 8 hours. Unlike existing exoskeleton frames which cost about 10,000 dollars, the Austin exoskeleton legs are designed to be more affordable and aim merely to get the wearer upright and moving forward. The prototype braces were named for a UC Berkeley student with paraplegia and developed to enable him to walk at graduation to receive his undergraduate diploma. The article includes links to one video demonstrating how the Austin exoskeleton works and another showing the student walking at the graduation ceremony.
