文字稿
This robot can automatically sort recyclable rubbish. The RoCycle system by M.I.T. has a soft, puncture-resistant hand. Pressure sensors on its fingertips detect an object’s size and material. It then autonomously places the item in the appropriate recycle bin.
這個機器人能自動分類可回收的垃圾。麻省理工學院的 “RoCycle” 系統用一只柔軟的、防穿刺的手來分揀回收垃圾。指尖上的壓力傳感器可以探測到物體的大小和材質。然后它自動將物品放入相應的回收垃圾箱。

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.

“單憑計算機視覺，這些系統無法將紙張與塑料分開。許多紙杯和塑料杯看起來是一樣的，但是通過引入擠壓物體的能力，并辨別它是否有彈性、可彎曲，我們則能夠超越現有的方法。”
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.
該系統的目標是降低后端回收成本。目前，它識別靜止物體的準確率為 85%，但在模擬輸送帶上的準確率僅為 63%。
A common error was identifying paper-covered tins as paper. But how are researchers looking to improve the system?
一個常見的錯誤是把外包裝由紙覆蓋的金屬罐頭盒識別成紙。那么研究人員在如何改進這個系統？

We plan to create a much more detailed sensorised skin. We plan to develop the hand at different sizes and we plan to improve our algorithms for recognition. We’re very excited to see the use of robot automation in solving a problem that matters globally.
