弹性网格状材料的结构可以调整，以实现所需的机械性能，在机器人技术的许多应用中有很大的希望。然而，现有的方法依赖于晶格节点处的全熔合连接，这限制了可以实现的机械性能的范围。在这项工作中，我们介绍了可编程数字编织-3D打印，纺织类材料与滑动连接，模仿传统编织织物的纱线结构。我们的方法允许交叉股之间的相对运动，从而解锁可编程的非线性和各向异性材料行为的大空间。正如我们通过一组虚拟和物理实验所展示的那样，这种新概念扩展到各种各样的图案，从类似于传统编织织物的正交股线的规则排列到弯曲纱线，交织闭环和专用股线用于驱动。
Elastic lattice-like materials whose structures can be tuned to achieve desired mechanical properties hold great promise for many applications in robotics. However, existing methods rely on all-fused connections at lattice nodes, which limits the range of mechanical properties that can be achieved. In this work, we introduce Programmable Digital Weaves---3D-printable, textile-like materials with sliding connections that mimic the yarn structure of conventional woven fabrics. Our method allows for relative motion between crossing strands, thus unlocking a large space of programmable nonlinear and anisotropic material behavior. As we demonstrate through a set of virtual and physical experiments, this new concept extends to a wide variety of patterns, ranging from regular arrangements of orthogonal strands similar to conventional woven fabrics to curved yarns, interlacing closed loops, and dedicated strands for actuation.
