摘要:

最近,集成在机器人系统中的可充气元件已经能够通过简单的输入实现复杂的运动。然而,这些流体致动器通常在膨胀时表现出单峰变形。在这里,我们提出了一种新的设计概念,模块化,流体致动器,可以切换变形模式之间的输入阈值的响应。我们的系统包括折叠折纸模块,其中抢购打破旋转对称性,使访问弯曲变形。通过调整几何形状,模块可以被设计成在不同的压力阈值下卡扣,在致动时顺时针或逆时针旋转,以及在不同的平面中弯曲。由于它们能够假设多种变形模式作为对单个压力输入的响应,我们称我们的系统为MuA-Ori,或多模态驱动折纸。MuA-Ori提供了一个理想的平台来设计执行器,这些执行器可以在不同的配置之间切换,到达空间中的多个预定义目标,并沿着复杂的轨迹移动。

英文摘要:

Recently, inflatable elements integrated in robotics systems have enabled complex motions as a result of simple inputs. However, these fluidic actuators typically exhibit unimodal deformation upon inflation. Here, we present a new design concept for modular, fluidic actuators that can switch between deformation modes as a response to an input threshold. Our system comprises bistable origami modules in which snapping breaks rotational symmetry, giving access to a bending deformation. By tuning geometry, the modules can be designed to snap at different pressure thresholds, rotate clockwise or counterclockwise when actuated, and bend in different planes. Due to their ability to assume multiple deformation modes as response to a single pressure input we call our system MuA-Ori, or Multimodal Actuated Origami. MuA-Ori provides an ideal platform to design actuators that can switch between different configurations, reach multiple, pre-defined targets in space, and move along complex trajectories.
