Cambridge University scientists create robotic hand able to hold objects剑桥大学科学家研发出能抓握物体的机械手
科学家们设计了一种只凭手腕运动就能抓握物体的机械手。这只由英国剑桥大学研究团队研发的3D打印机械手中被放置了传感器，从而可以感知它所触摸的物体。
Researchers say their robotic hand canhandleitems that are currently1 toodelicatefor machines. The hand useswrist movementsand has sensors2 that developerslikento skin.
研究职员表示，他们研发的机械手可以操控现在对其它机器人来讲过于精致小巧的物品。机械手通过手腕运动工作，装有被研发职员称作像皮肤一样能感知物体的传感器。
The robot is able tojudgehow much pressure should be applied3 tograspdelicate objects, such as those made of glass, without breaking them. But what are thepractical usesof a robotic hand that can feel and grip4?
这只机械手可以判断在抓取像玻璃这种易碎物体时应用多大抓力才能拿稳但又不捏碎它们。不过，可以感知和抓握物体的机械手的实质作用与功效有什么呢？
Its 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, replacinghuman pickers.
虽然目前还处于早期阶段，但机器人学教授饭田史也表示，在将来，机械手可以用于医学和农业中。他觉得这种机械手臂可以代替人类采摘草莓等软的水果。
Eventually, Professor Iida says it could perform medical tests and reducediagnosis timesfor cancer and other conditions.
饭田教授说，终有1日大家可以用机械手来进行医学测试，从而降低癌症及其它疾病的诊断时间。
