Prosthetic limbs get more advanced all the time. Stanford Engineers have developed a more stable prosthetic foot that can handle challenging terrain. The tripod foot responds to rough terrain by “actively shifting pressure between three different contact points.”
As the researchers explain:
Chiu, Voloshina and Collins thought, might be a tripod with a rear-facing heel and two forward-facing toes. Outfitted with position sensors and motors, the foot could adjust its orientation to respond to varying terrain, much as someone with an intact foot could move their toes and flex their ankles to compensate while walking over rough ground.
