CELL PHONE OPERATED ROBOT
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.
.
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.

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.

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
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.
CONT..
ALARM PHONE DIALER By replacing DTMF Decoder IC
CM8870 by a 'DTMF Transceiver IC’ CM8880, DTMF tones can be generated from the robot.
CONCLUSION
Thus, we believe that our project will be beneficial for various purposes & hence our efforts will be fruitful.
