Now let’s read a passage about robots. 機器人發(fā)展史機器人大致經(jīng)歷了三代發(fā)展：第一代機器人是簡單個體機器人，只具有記憶、存儲能力，按相應(yīng)程序重復(fù)作業(yè)，但對周圍環(huán)境基本沒有感知與反饋控制能力。第二代機器人為群體勞動機器人。它能夠獲得作業(yè)環(huán)境和作業(yè)對象的有關(guān)信息，進行一定的實時處理作業(yè)，在工業(yè)生產(chǎn)中得到廣泛應(yīng)用。第三代機器人是目前正在研究的“智能機器人”。它不僅具有更加完善的環(huán)境感知能力，而且具有邏輯思維、判斷和決策能力，可根據(jù)作業(yè)要求與環(huán)境信息自主進行工作。 T：Today we’ll learn an article about robots.
