This project proposes to utilize the superior mechanical properties of statically and kinematically determinate truss structures (as defined by Maxwell's rule) in a novel way-to create a three-dimensional morphing system that provides both efficient propulsion and high maneuverability. The idea is to take advantage of the stiffness and strength of these structures, and enable them to change shape by replacing some of the passive members with actuators. This project will then study the feasibility of using this structure as the basis of a low powered, biomimetic-actuating system that can achieve the propulsive and control capabilities of the dolphin and manta ray. The goal is to use this project as a first step in generating a bio-inspired autonomous underwater vehicle (AUV), capable of performing tasks where it would be dangerous for humans to go. To achieve the project's goals, the Principle Investigator will integrate the sciences of biomechanics, adaptive multifunctional materials, and artificial muscles.

本计画提出利用静定与动定桁架结构（由麦克斯韦法则所定义）的上级机械特性，以一种新颖的方式来创造一个三维变形系统，提供有效的推进力与高机动性。 这个想法是利用这些结构的刚度和强度，并使它们能够通过用致动器代替一些被动构件来改变形状。 然后，该项目将研究使用这种结构作为低功率仿生驱动系统的基础的可行性，该系统可以实现海豚和曼塔的推进和控制能力。 目标是将该项目作为产生生物启发的自主水下航行器（AUV）的第一步，能够执行人类可能会遇到危险的任务。 为了实现该项目的目标，首席研究员将整合生物力学，自适应多功能材料和人造肌肉的科学。
