折纸可以把一张纸变成复杂的三维形状，类似的折叠技术可以产生结构和机制。为了演示这些技术在机器制造中的应用，我们开发了一种能够自动折叠的爬行机器人。机器人一开始是一个嵌入了电子设备的平板，然后自动转变为一台功能正常的机器。为了做到这一点，我们开发了形状记忆复合材料，可以沿着嵌入的铰链折叠自己。我们使用这些复合材料重建了基本的折叠图案，这些图案源自计算折纸，可以外推到广泛的几何和机制上。这个以折纸为灵感的机器人可以在4分钟内折叠自己，并在没有人工干预的情况下离开，展示了复杂的自动折叠机器和自主、自我控制组装的潜力。
Origami can turn a sheet of paper into complex three-dimensional shapes, and similar folding techniques can produce structures and mechanisms. To demonstrate the application of these techniques to the fabrication of machines, we developed a crawling robot that folds itself. The robot starts as a flat sheet with embedded electronics, and transforms autonomously into a functional machine. To accomplish this, we developed shape-memory composites that fold themselves along embedded hinges. We used these composites to recreate fundamental folded patterns, derived from computational origami, that can be extrapolated to a wide range of geometries and mechanisms. This origami-inspired robot can fold itself in 4 minutes and walk away without human intervention, demonstrating the potential both for complex self-folding machines and autonomous, self-controlled assembly.
