This Prosthetic Foot And Ankle Move With Incredibly Life-Like Motions

Developed by researchers at the Vrije Universiteit Brussel in Belgium, the Ankle Mimicking Prosthetic Foot 2.0 is not only designed to give wearers an incredibly natural and lifelike gait. It also features an energy-harvesting system to put a natural spring back into someone’s step.

Your average prosthetic uses a spring or elastic to store and repurpose energy from a downward step to propel the wearer forward, but it’s a passive approach that doesn’t precisely mimic the motion and actions of a human leg. The AMP Foot 2.0, on the other hand, uses a lightweight motor powering an actuator and a specially designed locking release mechanism.

The actuator ensures there’s always enough stored energy to push-off someone weighing up to 75kg at every step, while the timed release mechanism matches the natural motion of someone walking on flat ground. What’s most impressive is that the prosthetic weighs just 3kg, which is close to the weight of a human foot. So in theory it wouldn’t take someone long to learn to walk with the new prosthetic.

    That's cool and all, very nice stride too... Pretty sure they could have reduced the vid by about two and a half minutes though..! :)

      Haha yeah after 30 seconds I scrubbed froward to see if he started running..

    "the prosthetic weighs just 3kg,"

    An average man's size 9.5 foot weighs about 2.3 pounds.

    2.3 pounds = 1.043 262 451 kilos

    Major Fail!

      Not sure what you're looking at, but I see the leg missing from the knee down... so....
