瑞典中部的一个垃圾填埋场上,一个机器人一边移动一边发射激光。这个机器人的任务是探测垃圾填埋场大气中的甲烷含量。甲烷不仅会引起爆炸(瓦斯的主要成分是甲烷),而且会造成温室效应。最近一项研究指出,研究人员通常会低估空气中的甲烷含量,部分原因是因为甲烷难以检测。为解决这个问题,瑞典研究人员开发了这种机器人。机器人沿着设定的路线巡视,同时向前方30米范围内发射激光束。激光束被设定为特定波长,以便能够被甲烷等目标气体分子吸引。传感

On a landfill in central Sweden, a robot lashes while moving. The mission of this robot is to detect the methane content of the landfill’s atmosphere. Methane not only causes an explosion (the main component of methane is methane) but also contributes to the greenhouse effect. A recent study indicated that researchers often underestimate methane in the air partly because methane is difficult to detect. To solve this problem, Swedish researchers developed this robot. The robot patrols along the set route and simultaneously emits a laser beam within 30 meters of the front. The laser beam is set to a specific wavelength so that it can be attracted to target gas molecules such as methane. Sensing
