2. ROBOT
A robot is a mechanical or virtual intelligent
agent that can perform tasks automatically or
with guidance, typically by remote control. In
practice a robot is usually an electro-
mechanical machine that is guided by computer
and electronic programming.
.

3. DTMF
Dual-tone multi-frequency signaling (DTMF)
is used for telecommunication signaling over
analog telephone lines in the voice-frequency
band between telephone handsets and other
communications devices and the switching
center.

8. COMPONENT USED
 RESISTORS
 CAPACITORS
 OSCILLATORS
 IC 8870
 IC 293D
 IC 74LS04
 MICROCONTROLLER 89V51RD2

9. SOFTWARE USED
 EXPRESS PCB
This is software use to design PCB layout it is very
easy to use have various component to work with.
 KEIL
To burn microprocessor Keil software is used.

10. APPLICATIONS
 SCIENTIFIC
 MILITARY
 SEARCH AND RESCUE

11. FUTURE SCOPE
 ADDING CAMERA
If the current project is interfaced with a
camera (e.g. a Webcam) robot can be driven
beyond line-of-sight & range becomes
practically unlimited as networks have a very
large range

12.  IR SENSOR
IR sensors can be used to automatically
detect &avoid obstacles if the robot goes
beyond line of sight. This avoids damage
to the vehicle if we are maneuvering it from
a distant place.
 PASSWORD PROTECTION
Project can be modified in order to
password protect the robot so that it can be
operated only if correct password is
entered.

13. CONT..
 ALARM PHONE DIALER
By replacing DTMF Decoder IC CM8870 by
a 'DTMF Transceiver IC‟ CM8880, DTMF
tones can be generated from the robot.

14. CONCLUSION
Thus, we believe that our project will be
beneficial for various purposes & hence our
efforts will be fruitful.
