The document discusses different types of machines. It classifies machines as either simple machines or complex machines. Simple machines include electrical appliances that use electricity from outlets or batteries to operate, as well as forms of transportation like cars and bikes that use fuel or human energy. Complex machines are robots used for manufacturing that can perform jobs more quickly, efficiently and safely than humans.

4. Electrical appliances
Electrical appliances in our homes such as washing machines and cookers use electricity
from the mains and calculators at school use electricity from batteries.
Forms of transport
Forms of transport such as cars, buses and lorries use fuels like petrol and
diesel to work. Bicycles use energy from people.
Robots at work
At work we use robots to make mass-produced products. Robots can be
quicker than people an the can do jobs that are dangerous for people.

from batteries and some use solar energy
