ABSTRACT Biosyncretic robots that integrate living materials present unique advantages for advancing robotic research. Compared with traditional robots, biosyncretic offer potential benefits such as higher energy efficiency and enhanced biocompatibility. Among various bioactuators, skeletal muscle tissue (SMT) is particularly favored its scalability, to generate high driving forces, controllable on/off actuation. However, current SMT actuators often face challenges, including a limited force suboptimal practical designs, which may impede the development of robots. To address these limitations, this work proposes method fabricating modular actuators. By leveraging biomimetic design structural optimization, contractile performance significantly improved. The achieved maximum 2.92 ± 0.07 mN, demonstrated approximately 28% strain under unloaded conditions, notably exhibited responsive single‐twitch contractions electrical stimulation frequencies up 10 Hz. This response outperforms most existing robot studies. In addition, highly adaptable can be easily assembled construct human‐like actuators, convergent, parallel, bipennate muscles. integrating rigid‐flexible coupled nonliving structures, SMT‐driven caterpillar, dolphin, manta ray have been successfully developed. research presents an innovative approach constructing large, high‐performance, multifunctional contributing advancements in both (or biohybrid robots) engineering.
