robotics this is an scientific
imformation we are going to
talk about the benefies of the
gears, for what they are
used?,and were does the
gears are used?.

4. 1. Easy to use in machines that works
together with other gears.
2. Can be used in engines or in
mechanisms As the bicycle or motor.
3. It facilitates daily life.
4. It facilitates the work in industries .
