File this under: amazing robots. Researchers at the University of Arizona have developed a set of robotic legs with a near-perfect human gait. While “it’s not able to balance itself, the resulting robot, researchers say, is as close as we’ve gotten to an accurate representation of human walking.” Continue reading for a video and more information.
To make it possible, researchers set up a fake half-center, a simple neural network of two neurons that fire interchangeably, producing the rhythm of human walking, while sensors in the robot send feedback about its environment. Researchers believe babies might operate on a similar half-center system, even before they walk, and that a half-center might be what provides a framework for people with spinal cord injuries to re-learn how to walk.
