这个机器人能自动分类可回收的垃圾。麻省理工学院的“RoCycle”系统用一只柔软的、防穿刺的手来分拣回收垃圾。指尖上的压力传感器可以探测到物体的大小和材 质。然后它自动将物品放入相应的回收垃圾箱。

With computer vision alone, the systems are not able to separate paper from plastic. Many paper and plastic cups look the same, but by introducing the ability to squeeze the objects and to know whether it’s flexible or not – we are able to go one step beyond what today’s methods can do.

麻省理工学院计算机科学与人工智能实验室 “单凭计算机视觉,这些系统无法将纸张与塑料分开。许多纸杯和塑料杯看起来是一 样的,但是通过引入挤压物体的能力,并辨别它是否有弹性、可弯曲,我们则能够超 越现有的方法。”

The goal of the system is to reduce the back-end cost of recycling. It currently has 85 percent accuracy in identifying stationary items, but only 63 percent accuracy on a simulated conveyer belt.

该系统的目标是降低后端回收成本。目前,它识别静止物体的准确率为 85%,但在模 拟输送带上的准确率仅为 63%。


A common error was identifying paper-covered tins as paper. But how are researchers looking to improve the system?
一个常见的错误是把外包装由纸覆盖的金属罐头盒识别成纸。那么研究人员在如何改进这个系统?

3. What does Hubbub suggest taking when buying your food for lunch?
Hubbub suggests taking your own container to a shop and asking them to put your food in it.

4. True or false? In a trial in East Anglia, more customers brought their own lunch boxes when they got a reduction on the quantity of food they bought.
False. In a trial in East Anglia, a 10% price reduction persuaded some customers to come prepared with their own lunch box.

5. What phrase is used in the article to mean ‘action that gets closer to a successful result’?
The phrase is ‘a step in the right direction’. "The idea of using reusable coffee cups for hot drinks and refilling water bottles has already proved successful so this could be another step in the right direction."
