In 1995 about 700,000 robots were
operating in the industrialized world. Over 500,000 were used in Japan, about
120,000 in Western Europe, and about 60,000 in the United States. Many robot
applications are for tasks that are either dangerous or unpleasant for human
beings. In medical laboratories, robots handle potentially dangerous materials,
such as blood or urine samples(尿样). In other cases, robots are used in
repetitive, unchangeable tasks in which human performance might degrade over
time. Robots can perform these repetitive, high-precision operations 24 hours a
day without fatigue. A major user of robots is the automobile industry. General
Motors Corporation uses approximately 16,000 robots for tasks such as spot
welding(点焊), painting, machine loading, parts transfer, and assembly. Assembly
