在美国高楼耸立的城市中存在着许多问题,煤气管道爆炸的危险就是其中之一。在城市中,公寓、办公楼都使用煤气,从而在街道及楼房下面形成了一个庞大的煤气管道网。迷宫式的煤气管道网中一旦漏气,随时都有爆炸的危险。但漏气的检查是很困难的。芝加哥煤气公司及煤气研究所研制出一种煤气管道检漏机器人,名叫提修斯(这是雅典王子的名字,他曾进入克里特迷宫斩妖除怪),也称作管道机器人老鼠。它的研制费用已花了几百万美元。其它的公用事业公司研制的机器人一般只能在较大的干线管道中工作,而机 There are many problems in cities where tall buildings in the United States rise, and the danger of a gas pipeline explosion is one of them. In cities, gas is used in apartments and office buildings, creating a huge network of gas pipelines below streets and buildings. Once the labyrinth gas pipeline network leaks, there is the danger of explosion at any time. But the leak check is very difficult. Chicago Gas Company and Institute of Gas developed a gas pipeline leak detection robot named Titus (this is the name of the Prince of Athens, he had entered the Cretan maze, demon demon), also known as the pipe robot mouse. Its development costs have cost millions of dollars. Robots developed by other utilities typically only work on larger trunk lines, and machines
