项目摘要

This project will create improved methods of dynamic modeling for highly deformable structures. It will show how miniature hydraulic systems can be customized for power transmission in challenging soft robotic applications, and how textiles and elastic rubbers can be combined to manufacture novel fluid-powered soft actuators. It will demonstrate the use of embedded fiber optic sensors to measure soft robot shape. These advances will be integrated into a design framework for a new class of soft robots that can safely work with and around people, and that can reconfigure themselves to adapt to a changing environment. This project will be a significant advance towards realizing the transformative potential of soft robots in healthcare, manufacturing, agriculture, exploration, environmental monitoring, and national security. Two experimental testbeds representing the diversity of applications will validate the results of the project -- a soft tentacle-like robot will perform simulated orthopedic surgery and a soft eel-like robot will demonstrate swimming and climbing for navigating and exploring challenging environments. Outreach activities at the participating universities will encourage local communities to see, touch, and learn about the most recent scientific developments in soft robotics, reaching an estimated 10,000 people annually in Nashville, Knoxville, and Tallahassee.For soft robots to fulfil their enormous promise, fundamental research is needed in modeling, sensing, actuating, and controlling soft robots that are underactuated, have infinite degrees of freedom, and are highly influenced by interaction with humans, other robots, the environment, and even themselves. The intellectual contribution of this research in modeling, estimation, and control will extend dynamic Cosserat rod theory to account for soft robot cross section deformations. In sensing, novel fiber optic shape sensor technology will reveal new fundamental knowledge of soft robot shape and interaction in real-time and without line-of-sight restrictions. In design, new manufacturing methods that use a 2D fabrication approach with multifunctional and task-specific material layers will create complex scalable 3D structures, and high power-density miniature hydraulic power systems will be developed as the future of actuation and power transmission for soft robotics.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将为高变形结构创建改进的动态建模方法。它将展示如何在具有挑战性的软机器人应用中定制微型液压系统以实现动力传输，以及如何将纺织品和弹性橡胶结合起来制造新型流体驱动的软执行器。它将演示如何使用嵌入式光纤传感器来测量软体机器人的形状。这些进步将被整合到新型软机器人的设计框架中，这些机器人可以安全地与人一起工作以及在人周围工作，并且可以重新配置自身以适应不断变化的环境。该项目将是实现软机器人在医疗保健、制造、农业、勘探、环境监测和国家安全领域变革潜力的重大进步。代表应用多样性的两个实验测试台将验证该项目的结果——一个类似触手的软机器人将执行模拟骨科手术，一个类似鳗鱼的软机器人将演示游泳和攀爬，以导航和探索具有挑战性的环境。参与大学的外展活动将鼓励当地社区观看、触摸和了解软机器人技术的最新科学发展，预计每年覆盖纳什维尔、诺克斯维尔和塔拉哈西的 10,000 人。需要对软机器人进行建模、传感、驱动和控制方面的基础研究，这些机器人是欠驱动的，具有无限的自由度，并且受到与人类、其他机器人、环境甚至自身交互的高度影响。这项研究在建模、估计和控制方面的智力贡献将扩展动态 Cosserat 杆理论来解释软机器人横截面变形。在传感领域，新型光纤形状传感器技术将实时揭示软机器人形状和交互的新基础知识，且不受视线限制。在设计中，使用具有多功能和特定任务材料层的 2D 制造方法的新制造方法将创建复杂的可扩展 3D 结构，并且高功率密度微型液压动力系统将被开发为软机器人驱动和动力传输的未来该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
