2. Robot is an invention of the moderntimes. A robot is a
mechanical or virtualintelligent agent that can performtasks
automatically or with guidance,typically by remote control. an
electro-mechanical machine that isguided by computer and
electronicprogramming. Today, over one million householdrobots, and
a further 1.1 millionindustrial robots, are
operatingworldwide.
3. ASIMO - advanced step in innovative mobility. TOPIO - tosy
ping pong playing robot.
4. Line follower is a machine that can follow a path. The path
can bevisible like a black lineon a white surface (or vice-versa).
Path can be invisiblelike a magnetic field.
5. CHASSIS: the main frame of the robot, the body which holds
the motor, wheels and the batteries.
6. WHEELS: wheels are mainly of two types , one is the attached
to the motors at the back which is used for steering and another
castor wheel in front, which allows 360 degrees free rotation and
avoids friction on the ground. BATTERIES: used for supplying power
to a robot, Zinc carbon batteries can be used.
7. POWER SUPPLY: the voltage regulator regulates thesupply if
the line voltage increases or decreases. Theseries 78xx regulators
provide fixed regulated voltagesfrom 5 to 24 volts.ELECTRONIC
CIRCUITRY:Input Section.Output section.Control section.
8. MOTORS: as car needs an engine to run, similarlyrobot also
needs something to make it run.it is amechanical device which cause
movement to robo.such as stepper motor servo motor or dc motor
etc.

10. The robot uses IR(infrared) sensors to sense the line.
Output of the sensors is an analog signal which depends onthe
amount of light reflected back. This analog signal is given to the
comparator toproduce 0s and 1s which are then fed to the uC.Then
microcontroler decides the position of robot in lefttor right
direaction.
11. Industrial automated equipment carriers.Automated cars.Tour
guides in museums and other similarapplications.Deliver the mail
within the office buildingDeliver medications in a hospital.
12. The robot must be capable of following a lineThe robot must
also be capable of following aline even if it has breaks.The robot
must be insensitive to environmentalfactors such as lighting and
noise.It should be capable of taking various degrees ofturnsThe
color of the line must not be a factor as longas it is darker than
the surroundings.
13. LFR can move on a fixed track or path.It requires power
supply.Lack of speed control makes the robot unstableat
times.Choice of line is made in the hardwareabstraction and cannot
be changed by software.
14. LINE FOLLOWER IS A MECHINE THAT CANFOLLOW A PATH.THE PATH
CAN VISIBLE LIKE WHITE LINE ONBLACK SIRFACE.PATH CAN BE INVISIBLE
LIKE MAGNET FIELD
