The document presents a seminar on a DTMF based robot. It discusses what an embedded system and robot are, how DTMF signaling works, and provides block and circuit diagrams of the robot. It describes using a DTMF decoder and ATmega 168 microprocessor with software like Express PCB and Arduino/Kiel. Applications include scientific, military, and search and rescue uses. The future scope involves adding a camera, IR sensors, and password protection. It also discusses moving towards wireless control and the growing role of embedded systems in devices and vehicles.

A
SEMINAR ON
DTMF BASED ROBOT

2. WHAT IS EMBEDDED
SYSTEM?
 An electronic device which incorporates a
microprocessor within its implementation is called
embedded system.

3. WHAT IS ROBOT?
 A robot is a mechanical or virtual
intelligent agent that can perform task
automatically or within guidance,
typically by remote control.
 In practical it can be called as electro-
mechanical machine.

4. DTMF
 Dual tone multi frequency signaling is used for
telecommunication signaling over analog
telephone lines invoice frequency band
between telephone headset and other
communication devices and switching centers.

5. TOUCH TONE

6. BLOCK DIGRAM

7. CIRCUIT DIGRAM

8. DTMF DECODER

9. ATMEGA 168

10. SOFTWARES USED
 Express PCB
This software is used to design PCB layout
 Aurdino or Kiel
To burn microprocessor

11. APPLICATIONS
 Scientific
 Military
 Search and rescue

12. FUTURE SCOPE
 Adding camera
If robot is interface with camera robot can drive
beyond line of sight and range can become
unlimited.

13.  IR sensor
IR sensor can be used to automatically detect or avoid
obstacle.
 Password protection
It can modify the ROBOT

14. ALARM PHONE DIALER
 By replacing DTMF decoder IC by DTMF
trans-receiver IC CM8880 DTMF tones can be
generated form robot.

15. MOVING TOWARDS
WIRELESS

16. FUTURE OF EMBEDDED
SYSTEM
 Embedded system accounts for 100% world
with microprocessor production.
 Embedded processor in house 40-50 approx.
 Embedded processor in modern cars 50-60%.

17. Just as the Personal Computer was a symbol of 80’s……
The symbol of 90’s will be World Wide web , the
Next non Liner shift is going to be advent of
Wireless Network !!!!
