This document discusses different types of robots and their components. It describes line follower robots, which use sensors to follow a line, and obstacle follower/avoider robots, which sense and react to obstacles. It also describes a mobile operated robot that can be controlled via dual tone multiple frequency (DTMF) tones from a mobile phone. Key robot components discussed include microcontrollers, chassis, actuators, power supplies, sensors, and programming.

7. Mobility: It possesses some form
of mobility.
Programmability: It can be
programmed to accomplish a large
variety of tasks. After being
programmed, it operates
automatically.
Sensors: on or around the device
that are able to sense the

8. Mechanical capability: enabling it
to act on its environment rather
than merely function as a data
processing or computational device
(a robot is a machine); and
Flexibility: it can operate using a
range of programs and manipulates
and transport materials in a variety
of ways.

9. ..  First Law A robot may not
injure a human
being, or, through
inaction, allow a human
being to come to harm.

12. (FOLLOW THE LINE VIA
TWO SENSORS)

13. It is a robot which
follows the line with the
help of dual IR sensors . In
the sensors there are led’s
which emit the IR
radiations and then receive
the reflected radiations.

16. Obstacle follower is a
robot which sense the
presence of obstacle with
the help of sensor and
follow the object
It can be of two types -
Single sensor obstacle follower
Double sensor obstacle follower

17. .

18. Obstacle avoider is the robot
which sense the obstacle and avoid
it (change its path without
touching the obstacle )
For eg………
If you leave the robot in a room
full of objects it will not collide to
any of the object or any of the
wall.
It is of two types
 Single sensor obstacle avoider
 Double sensor obstacle avoider

20.  MOBILE OPERATED ROBOT USING
DTMF (DUAL TONE MULTIPLE
FREQUENCY)
 The robot is controlled by a mobile phone
that makes call to the mobile phone
attached to the robot in the course of the
call, if any button is pressed control
corresponding to the button pressed is
heard at the other end of the call. This
tone is called dual tone multiple frequency
tone (DTMF) robot receives this DTMF
tone with the help of phone stacked

22. Working
 In order to control the robot, you have
to make a call to the cellphone
attached to the robot from any
phone. Now the phone is picked by
the phone on the robot through auto
answer mode. Now when you press 2
the robot will move forward when you
press 4 the robot will move left
when you press 8 the robot will move
backwards when you pressed 6 the
robot will move right.
