[AMP-L] Robotic Leg Prosthesis Replicating Biomechanics of the Knee

[Wayne Renardson]

via Science Robotics:

A lightweight robotic leg prosthesis replicating the biomechanics of 
the knee, ankle, and toe joint.

Robotic leg prostheses promise to improve the mobility and quality of 
life of millions of individuals with lower-limb amputations by 
imitating the biomechanics of the missing biological leg.  

Unfortunately, existing powered prostheses are much heavier and 
bigger and have shorter battery life than conventional passive 
prostheses, severely limiting their clinical viability and utility in 
the daily life of amputees.
