How fish muscles became blueprints for smarter underwater robots

Researchers at the Intelligent Biomimetic Design Lab at Peking University have developed a bio-signal framework showing that fish muscles do far more than generate swimming motion. In a series of studies led by Xie Guangming, Professor at the School of Advanced Manufacturing and Robotics, and carried out by twin brothers Waqar Hussain Afridi and Rahdar Hussain Afridi, muscle electrical signals were used to reconstruct body posture, infer surrounding flow conditions, and transfer biological principles to robotic systems. These findings open new directions in biological telemetry, locomotion research, and bio-inspired underwater robotics.
