From TFA: "We have demonstrated how a physical robot can create an "internal model" of itself, and then use that model to generate successful motor patterns for locomotion, before and after damage. Most current robotic systems plan their behavior using a built-in mathematical model whose from is provided externally by engineers. Some robots can adapt without a model, but require many physical trials. Our result shows that a machine can adapt without being given a model and without extensive trials, by gradually developing an internal model of itself."
