Vocabulary Notes from Science Level 3
A robot is a machine which can do things like people can. For
example, a robot might weld metal on cars in a factory.
This is a kind of machine that works by itself. For example, a space
ship without any people on it could be a robot. Often, a computer program
operates it. A good example is the robots that do welding (using
electricity to make heat and put two pieces of metal together) in Japanese
The work that would be most useful for a robot to do:
Building It would be useful because building work is dangerous
for people, so robots would make it safer. Another reason is the work is
not complicated, so a robot could do it. Also, robots could do repetitive
and simple work much faster than we can. In addition, robots are stronger
than people, so could carry more weight easily. Robots do not receive a
paycheck, so it would be cheaper than people. A robot is not bothered by
noise or bad weather like people are. Finally, robots follow a program, so
the work would be consistent.
Cleaning If a robot cleaned my house, I would have more
time to watch TV or play with my kids, or attend classes at the ALC.
Cleaning can damage our skin, so a robot would help us to keep beautiful
hands. If I do the cleaning, dust and dirt gets into my face and lungs. A
robot would help me to avoid this health risk.
Farming robots because the work is hard, heavy and difficult.
Because people dislike this kind of job, so robots would not complain.
Because we can stay inside when it rains and let the robot go out. Because
food would be cheaper to grow in this way.
Building robots would be useful because we can make the
buildings in a factory. The robots would work faster and mass produce.
There may be problems if people make the robot work too fast, or they try
to “cut corners”.
Nanotechnology makes robots that are so small they can fit
inside your blood vessels. These robots could fix problems with your
heart, for example.
Some problems caused by using robots:
If we have robots, unemployment will increase. (Japanese auto welders
We may become big fat couch potatoes watching TV, playing Nintendo, and
dying of heart attacks.
