Harnessing complex body dynamics is a challenge in robotics, particularly when dealing with soft dynamics, which exhibit high complexity in interacting with the environment. Recent studies indicate that these dynamics can be used as a computational resource. Researchers in Japan demonstrated that bifurcations, including periodic and chaotic dynamics, could be embedded into the pneumatic artificial muscle, with the entire bifurcation structure using the framework of physical reservoir computing. Their results suggested that dynamics not present in training data could be embedded through bifurcation embedment, implying the capability to incorporate various qualitatively different patterns into pneumatic artificial muscle without the need to design and learn all required patterns explicitly. According to the researchers their study introduced a novel approach to simplify robotic devices and control training by reducing reliance on external pattern generators and the amount and types of training data needed for control… read more.
