The document discusses a line follower robot project. It can follow black or white lines using sensors to detect the line. It has applications in commercial, domestic, and industrial settings by automatically transporting items along set paths. Some advantages are its commercial value and ability to improve efficiency. Limitations include only being able to follow angled lines within its mechanical range and relying on an unobstructed track. Problems can occur if sensors are damaged, motors malfunction, or component quality is poor.

follows a line, either a black line or
white line.
• Line follower actually senses the line
and run over it.

Domestic applications: These can also be used at homes for domestic purposes
like floor cleaning etc.
Automobile applications: These robots can also be used as automatic
cars running on roads with embedded magnets
Industrial Applications: These robots can be used as automated equipment
carriers in industries replacing traditional conveyer belts.

equipment carriers.
It can be used for home
floor cleaning for etc.
In hotels they are being
used for the transfer of
things from one place
to another following a
straight path

10. Track a line so if they turn too sharply or drift
and lose the track they do not recover.
Can only track an angle based on minimum
angle of mechanical structure so will lose
track if the angle of the line is too tight.
Need a specific item (like a line) to follow
and any obstruction or damage will confuse
it.
