摘要

许多动物,如大象和章鱼,可以改变四肢和躯干的硬度。这使它们能够在周围环境中移动,并抓住东西移动。我们希望我们的软体机器人也能做到这一点!我们可以使用一种叫做 "干扰 "的技术来做到这一点。在这种技术中,躯干中的材料被挤压在一起,从而改变其硬度。干扰技术已被广泛应用于各种软体机器人中,例如用于轻轻拾取水果和蔬菜的机械手、外骨骼服和手术器械。在本文中,我们将介绍软体机器人中使用的三种主要干扰类型,并展示它们在实际生活中的应用。你猜怎么着?在文章的最后,我们将介绍如何利用干扰来制造一个机器人大象躯干,它可以像真正的大象躯干一样改变硬度!

Jellyphant: A Soft, Elephant Trunk-Inspired Robotic Arm That Can Grab Objects
Many animals, such as elephants and octopuses, can change the stiffness of their limbs and trunks. This allows them to move around their environments as well as grab things and move them around. We would love our soft robots to be able to do the same! We can do this using a technique called jamming, in which the materials in the trunk are packed together to change its stiffness. Jamming has been used in all sorts of soft robots, like robotic hands for gently picking up fruits and vegetables, exoskeleton suits, and surgical instruments. In this article, we will talk about the three main types of jamming that are used in soft robotics, and show how they can be used in real life. And guess what? At the end of the article, we will describe the use of jamming to build a robotic elephant trunk that can change its stiffness, just like a real elephant’s trunk!
