项目摘要

This project envisions a new class of soft robotics technology that will enable new multifunctional soft robots with reconfigurable actuation and shapes. The key to the proposed technology is the ability to change the mechanical properties of a thin-walled structure by changing its local curvature. For example, curving a flat sheet of paper along one direction greatly increases its stiffness in the other two directions. Exploiting the coupling between curvature and mechanical behavior in planar materials will enable the design, modeling, and control of reconfigurable soft robots. This can be used to realize robot arms with joints that can be created and configured at will to match desired task dynamics and constraint geometries. Soft robotics technology has the potential to transform the way our society utilizes and interacts with robots, because soft robots are inherently safe for interaction with humans. This project promotes the progress of science by advancing understanding of how to utilize materials and geometry to create active, assistive, robotic devices. Furthermore, the topics of this proposal are uniquely suited to outreach activities for K-12 students. Parallel outreach activities will be run across the collaborating sites to maximally inform the public and the nation?s youth about this new type of soft robot.This project will develop modeling, control, and design methods for a new class of robots formed from soft planar materials and called Soft Curved Reconfigurable Anisotropic Mechanisms (SCRAMs). These robots will be manufactured through planar fabrication methods (sewing, lamination, and 3D printing) and local, embedded actuators and sensors to realize soft, curved, reconfigurable, anisotropic mechanisms for reconfigurable joints with controllable curvature. The collaborative research plan features the following tasks: 1) identify geometric and manufacturing representations that can unify element design & will enable modeling, system simulation, and control, 2) establish and study canonical soft continuum elements, sensors, and actuators using experimental techniques and finite element modeling to understand SCRAM mechanics and dynamics towards a library of modular elements for building soft continuum systems. The project will 3) formulate new modeling, simulation, and geometric control methods for optimal control of SCRAM robots in multi-modal environments, 4) which will be validated on two SCRAM platforms to study issues in manipulation and locomotion as well as to demonstrate the potential of SCRAM-based soft-robots.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.

该项目设想了一种新型软机器人技术，该技术将使新型多功能软机器人具有可重新配置的驱动和形状。该技术的关键是能够通过改变薄壁结构的局部曲率来改变其机械性能。例如，沿一个方向弯曲一张平板纸会大大增加其在其他两个方向上的刚度。利用平面材料中曲率和机械行为之间的耦合将能够实现可重构软机器人的设计、建模和控制。这可用于实现具有可随意创建和配置的关节的机器人手臂，以匹配所需的任务动态和约束几何形状。软机器人技术有潜力改变我们社会利用机器人和与机器人互动的方式，因为软机器人本质上与人类互动是安全的。该项目通过增进对如何利用材料和几何形状来创建主动辅助机器人设备的理解来促进科学进步。此外，该提案的主题特别适合 K-12 学生的外展活动。并行的推广活动将在合作地点进行，以最大程度地向公众和国家年轻人介绍这种新型软机器人。该项目将为由软平面形成的新型机器人开发建模、控制和设计方法。材料，称为软曲线可重构各向异性机构（SCRAM）。这些机器人将通过平面制造方法（缝纫、层压和 3D 打印）以及本地嵌入式执行器和传感器来制造，以实现具有可控曲率的可重构关节的柔软、弯曲、可重构、各向异性机构。该合作研究计划的任务如下：1）确定可以统一元件设计并实现建模、系统仿真和控制的几何和制造表示，2）使用实验技术和方法建立和研究规范的软连续体元件、传感器和执行器。有限元建模，以了解 SCRAM 力学和动力学，构建用于构建软连续体系统的模块化元件库。该项目将 3) 制定新的建模、仿真和几何控制方法，以在多模式环境中优化控制 SCRAM 机器人，4) 将在两个 SCRAM 平台上进行验证，以研究操纵和运动问题并展示基于 SCRAM 的软机器人的潜力。该奖项反映了 NSF 的法定使命，并且通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
