Cambridge University scientists create robotic hand able to hold objects劍橋大學(xué)科學(xué)家研發(fā)出能抓握物體的機械手
科學(xué)家們設(shè)計了一種只憑手腕運動就可以抓握物體的機械手。這只由英國劍橋大學(xué)研究團隊研發(fā)的3D打印機械手中被放置了傳感器，從而能夠“感知”它所觸摸的物體。
Researchers say their robotic hand can handle items that are currently too delicate for machines. The hand uses wrist movements and has sensors that developers liken to skin.
研究人員表示，他們研發(fā)的機械手可以操控目前對其它機器人來說過于精致小巧的物品。機械手通過手腕運動工作，裝有被研發(fā)人員稱作像皮膚一樣能感知物體的傳感器。
The robot is able to judge how much pressure should be applied to grasp delicate objects, such as those made of glass, without breaking them. But what are the practical uses of a robotic hand that can feel and grip?
這只機械手能夠判斷在抓取像玻璃這類易碎物體時應(yīng)用多大抓力才能拿穩(wěn)但又不捏碎它們。不過，能夠感知和抓握物體的機械手的實際用途有哪些呢？
It's early days, but robotics Professor Fumiya Iida says that, in the future, it could be used in medicine and agriculture. He believes the arm could handle soft fruits such as strawberries, replacing human pickers.
雖然現(xiàn)在還處于早期階段，但機器人學(xué)教授飯?zhí)锸芬脖硎荆谖磥恚瑱C械手可以用于醫(yī)學(xué)和農(nóng)業(yè)中。他認為這種機械手臂可以代替人類采摘草莓等軟的水果。
Eventually, Professor Iida says it could perform medical tests and reduce diagnosis times for cancer and other conditions.
飯?zhí)锝淌谡f，終有一日人們可以用機械手來進行醫(yī)學(xué)檢測，從而減少癌癥及其它疾病的診斷時間。

答案
1.What are the sensors on the robot hand similar to?
The hand has sensors that developers liken to skin.
2.What example is given of delicate objects the hand can grasp without breaking?
Those made of glass.
3.How does Professor Iida think the hand could help in agriculture?
He believes itcould handle soft fruits such as strawberries, replacing human pickers.
4.True or false? The hand can perform medical tests.
False. Eventually, Professor Iidasays it could perform medical tests.
