요약Slender structures are ubiquitous in our world at all length scales-from interconnected axons in our brains and filamentary networks of fungal mycelium to coiling plant tendrils and the versatile elephant trunk. However, despite many mathematical models of passive slender structures, our understanding of the mechanics of active slender structures, in which internal activation governs their deformation, lacks a computationally efficient description. In the engineering world, developing a general theory of active slender structures would provide a unified model for fiber-based soft robotic arms and uncover insights into complex interactions among different deformation modes. Such a model could also quantitatively inform the biomimetic design of soft-robotic arms inspired by remarkable active slender structures of the animal kingdom. In this thesis, we simulate the deformation of active slender structures in real time to guide the control and design of bio-inspired soft robotics. We first present a reduced-order theory of the mechanics of active slender structures rooted in the general continuum mechanics of fibrillar activation. Using a dimensional reduction, we maximize the computational performance of specialized solutions to allow real-time simulation. We then leverage the high performance to solve and analyze inverse problems in control and design of active slender structures. Further, through physics-informed analysis of the elephant trunk, we develop a bio-inspired minimal soft-robotic design. We discover that the minimal design achieves a remarkably large workspace with only three contractile actuators. Our exploration of the design space and quantitative analysis of a reachability cloud atlas identify key principles and trends governing the control capabilities of fiber-based soft-robotic manipulators. We anticipate that our theory of active slender structures, together with the developed control and design insights, can apply to numerous other problems in science and engineering.
