The neural networks needed for walking may already be present in the common ancestor of stingrays and mammals
Scientists have found that the ancient ancestors of stingrays and humans could achieve efficient underwater walking using available body morphology, with very little energy and simple controls.Ancient vertebrates had everything they needed to walk underwater for millions of yearsThe study is published inThe Royal Society Interface magazine.
In their work, scientists have shown that the alternatingThe left-right gait originated with a simple algorithm based on reinforcement learning. The researchers built a bipedal robot to test their theory. The results confirmed the scientists' assumption.
This study not only sheds light onthe past, but also paves the way for the development of more efficient bioinspired robots in the future, the scientists note. In addition to energy efficient locomotion, scientists have found the robot has the ability to recover from serious disruptions.
