126 results about "Robot leg" patented technology

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. To have the robotic leg emulate human leg behaviors, surgeons must redirect the nerves that previously controlled some of the person’s lower-leg muscles to cause the thigh muscles to contract. Sensors embedded in the robotic leg measure the electrical pulses created by both a re-innervated muscle contraction, and the existing thigh muscle.
