Passage One
文章一
Researchers in the US have created a remote-controlled robot that is so small it can walk on the top of a US penny.
美国研究人员创造了一种遥控机器人，它非常小，可以在一美分硬币上面行走。
In research published in the journal Science Robotics, a team at Northwestern University said the crab-like robot is 0.5mm wide.
美国西北大学的一个研究小组在《科学机器人》杂志上发表的研究报告中指出，这个形似螃蟹的机器人只有0.5毫米宽。
Researchers described it as the smallest ever remote-controlled walking robot.
研究人员将其描述为有史以来最小的遥控行走机器人。
The tiny robot can bend, twist, crawl, walk, turn, and even jump without the use of complex hardware or special power.
这个微型机器人可以弯曲、扭转、爬行、行走、转弯，甚至跳跃，而无需使用复杂的硬件或特殊的动力。
The engineers said this is because the robot is powered by the elastic property of its body.
工程师说，这是因为该机器人的动力来自其身体的弹性特质。
To construct the robot, the researchers used a shape memory alloy material that transforms to its “remembered” shape when heated.
为了制造这个机器人，研究人员使用了一种形状记忆合金材料，这种材料在加热时会变成“记忆过的”形状。
Using a laser, the team is able to heat the robot at specific parts of its body, causing it to change shape.
研究小组利用激光可以加热机器人身体的特定部位使其改变形状。
As the robot deforms and goes back to its original shape, it creates movement from one place to another.
当机器人变形并恢复初始形状时，它就会从一个地方移动到另一个地方。
“Because these structures are so tiny, the rate of cooling is very fast,”project lead Professor John A. Rogers said.
项目负责人约翰·A.罗杰斯教授说:“由于这些结构非常微小，因此冷却速度非常快。”
In fact, reducing the sizes of these robots allows them to run faster.
事实上，缩小这些机器人的尺寸可以使它们运行得更快。
While the research is still in the exploratory phase, the team believes that technology could lead to micro-sized robots that can perform practical tasks in tightly confined spaces.
虽然这项研究仍处于探索阶段，但是研究小组相信，这项技术可以研制出能够在狭小的密闭空间内执行实际任务的微型机器人。
“You might imagine micro robots as agents to repair or assemble small structures or machines in industry, or as surgical assistants to clear clogged arteries, to stop internal bleeding, or to eliminate cancerous tumors, all in minimally invasive procedures,"Rogers said.
罗杰斯说:“你可以把微型机器人想象成在工业中修理或组装小型结构或机器的代理人,或者作为外科手术的助手，清理堵塞的动脉、止住内出血或消除癌性肿瘤，所有这些都是微创手术。”
