The studies of robot legs has made some development through the years, permitting precise movement and control.
Researchers at the Rehabilitation Institute of Chicago announced in September 2013 that they’ve developed a robotic leg that translates neural impulses from the person’s thigh muscle tissues into motion, which is the first prosthetic leg to achieve this. It is currently in testing.
Hugh Herr, head of the biomechatronics group at MIT’s Media Lab evolved a robotic transtibial leg (PowerFoot BiOM).
The Icelandic company Össur has also created a robot transtibial leg with motorized ankle that movements through algorithms and sensors that robotically adjust the attitude of the foot at some point of specific factors in its wearer’s stride. Also there are brain-controlled bionic legs that allow an character to move his limbs with a wi-fi transmitter.
