Skeletal muscle's elegant protein-based architecture powers motion throughout the animal kingdom, with its constituent actomyosin complexes driving intra- and extra-cellular motion. Classical motors recently developed soft actuators cannot match packing density contractility of individual muscle fibers that scale to power ants elephants alike. Accordingly, interdisciplinary fields robotics tissue engineering have combined efforts build living can a new class robots be more energy-efficient, dexterous, safe than existing motor-powered hydraulic paradigms. Doing so ethically at scale─creating meter-scale constructs from sustainable progenitor cell lines─has inspired innovations in biomaterials culture methodology. We weave discussions biology, materials chemistry, engineering, biohybrid design review state art actuator biofabrication. Looking forward, we outline vision for robotic systems tie recent progress long-term research goals.
