2 "bladerunners" using this sort of prosthetic foot. CGI image. The Flex-Foot Cheetah is a prosthetic human foot replacement developed by biomedical engineer Van Phillips, who had lost a leg below the knee at age 21; the deficiencies of existing prostheses led him to invent this new prosthesis.
He is known for the Flex-Foot brand of artificial foot and limbs that he created, [2] and for his charity work for amputees. [3] An amputee himself, having lost a leg below the knee at age 21, Phillips was motivated by the limitations of then-existing artificial limbs to attend the Northwestern University Medical School Prosthetic-Orthotic Center.
Each of six amputees' affected leg performance was compared against that of their biological leg. The team measured leg swing times and force applied to the running surface on a high-speed treadmill at the Biomechanics Laboratory of the Orthopedic Specialty Hospital, and also studied video of sprint runners from the Olympics and Paralympics ...
Aviva said, "The only thing that is artificial or fake about me is this!" She threw her artificial leg onto the table, adding, "And I'm sick of it!" She continued, "I'll crawl home.

A robotic leg powered by air muscles. A robot leg (or robotic leg) is a mechanical leg that performs the same functions that a human leg can. The robotic leg is typically programmed to execute similar functions as a human leg. A robotic leg is similar to a prosthetic leg. However, a robotic leg can be controlled electrically or mechanically.
