Robots
1. Most sophisticated (先进的) Japanese robots, which have vision systems and work at veryhigh speeds, are still based on American designs. Studies of robots, particularly computercontrol software, are considered to be generally less advanced in Japan than in America orEurope.
2. Although industrial robots were originally developed as devices for simply handling objects,today their commonest uses are for more skilled work like welding (焊接), spray-paintingand assembling components.
3. In Britain robot sales appropriately peaked in 1984, but have been declining ever since. Thisis partly because British wage rates are too low to make robots financially attractive and partlybecause engineers now have more experience with robots and are more aware of thedifficulties of introducing them effectively.
4. It has been calculated that a robot uses on average about 100 times more energy than a humanto do an equivalent job.
5. It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormousnumber because comics are so popular that they make up a third of all material published inJapan.
6. The reliability of robots is measured in their M. T. B. F. or mean time between failures. Thishas risen from about 250 hours in the mid-1970s to about 10, 000 hours today (equivalent to
working 18 hours a day for two years ). One way robot manufactures have increasedreliability is to test every single component they buy, instead of the normal procedure of justtesting a small sample.
7. The biggest single benefit of introducing robots claimed by Japanese companies is that theyincrease quality control. Once programmed, the robots can work more accurately andconsistently than humans, who can get tired and bored.
