  • 1. JAI NARAIN COLLEGE OF TECHNOLOGY & SCIENCE , BHOPAL Guided By:- Submitted To:- SubmittedBy:- Mr. Amit Mr. Ashok Harish Bhute Sawaskade Agarwal Mukesh Kr.Sharma Nikita Kaushal
  • 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.
  • 4. TOUCH TONE
  • 5. BLOCK DIAGRAM
  • 6. CIRCUIT DIAGRAM
  • 7. PCB LAYOUT
  • 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.
