Origami-Inspired Self-Assembling Robot Crawls By Itself

A team from Harvard's Wyss Institute, Harvard's SEAS, and MIT built an autonomous robot that starts out as a single composite sheet programmed to fold itself into a complex shape and crawl away without any human intervention. Credit: Harvard's Wyss Institute

已经开发出一种折纸风格的机器人,能够在短短四分钟内自我组装成复杂的形状 - 然后爬行。

该机器人通过组装后的每小时十分之一英里的速度走开,使用了令人惊讶的简单组件,包括收缩的Dinks™和Paper。

这项研究是由一支工程师和计算机科学家团队进行的,包括Wyss研究所,海洋和马萨诸塞州理工学院(MIT)的Rob Wood和Sam Felton,并已在Science.

The research could have a great impact on the design and assembly of robots, with progress in speed, cost and automation. The building process would also be complementary to 3D printing, which is becoming increasingly important in manufacturing.

在过去的几年中,该团队一直在设计许多机器人,其中这是第一个能够完全自组装的机器人,而无需任何人类干预。

借助计算机设计工具,Felton在尝试了40个原型后决定了折叠图案和合适的设计。他仅使用坚固的墨水打印机,一台激光机和手制造了初始纸。

自我折叠机器人

然后,他在平板上添加了两个电池,两个电动机和一个微控制器,微控制器充当机器人的“大脑”。该纸本身是由收缩的Dinks™(或聚苯乙烯)和纸制成的,两者之间有一个柔性电路板。

The sheet also comprised hinges pre-programmed to fold in a specific manner. Each hinge included an embedded circuit, which when signaled by the microcontroller produced heat. This heat causes self-folding of the composite sheet in a specific sequence.

"Getting a robot to assemble itself autonomously and actually perform a function has been a milestone we've been chasing for many years”.

四分钟后,铰链的冷却会导致聚苯乙烯的硬化,从而导致机器人变硬。然后,微控制器命令机器人走开。这个完整的序列消耗了与单个AA碱性电池中相当的能量。

机器人的功能链接到计时器,该计时器在安装电池后等待10秒以开始折叠过程。

According to Felton, this could be modified so that folding is triggered by a pressure or temperature sensor.

这种折叠技术的一部分是受自然过程的启发,尤其是从线性氨基酸序列折叠成具有高级功能的复杂蛋白的方式。

这项令人惊叹的研究是在最近的3D印刷,改变相位的材料的新闻之后,该材料可能导致机器人很容易变形为不同的形状。

有趣的是,University of Massachusetts at Amhersthas also released news today of research into how origami could be utilized to create new materials.

似乎是通过用于建造它们的材料和安排方式的材料来使机器人对自己的命运的控制权更大,这似乎是向前迈进的。亚博网站下载
