This document describes a DTMF controlled robot project. It includes a list of components used, descriptions of the Arduino, chassis, motors, integrated circuits, and circuit diagram. It explains how the robot works by receiving DTMF tones from a calling mobile phone, decoding the tones using an MT8870 chip, and sending signals to motors. It includes a flowchart, code, and references. The key aspects are that the robot is controlled remotely via DTMF tones from a calling mobile phone and uses an Arduino, motor driver, and DTMF decoder chip to receive tones and control motors accordingly.
Aim of project is to make use of mobile phone to control robot movement
The movement is controlled by pressing relevant keys on a mobile phone that makes a call to another mobile phone attached to the robot.
This is a simple DTMF based Cellphone controlled robotic vehicle using Microcontroller which is used for wide range of purposes in military and law enforcement, search and rescue operations and scientific purposes.

GSM Based Versatile Robotic Vehicle Using PIC Microcontroller Report.Abee Sharma
This project is designed to develop as a robotic vehicle that can be controlled by a cell phones. DTMF commands from a phone send to another cell phone which is mounted on the robotic vehicle. These commands are fed to a PIC microcontroller of 8-bit architecture to operate the vehicle movement through motor interface.
Conventionally Wireless-controlled Robots Use Rf Circuits, Which Have Limited Working Range, Limited Frequency Range and Limited Control. Use of a Mobile Phone for Robotic Control Can Overcome These Limitations. It Provides the Advantage of Robust Control, Working Range as Large as the Area of the Service Provider, No Interference with Other Controllers. Although the Appearance and Capabilities of Robot Vary Vastly, All Robots Share Feature of a Mechanical, Movable Structure Under Some Form of Control. The Control of Robot Involves Three Distinct Phases: Perception, Processing and Action. Generally, the Preceptors Are Sensors Mounted on the Robot, Processing is Done by the On-board Microcontroller or Processor, and the Task is Performed Using Motors or with Some Other Actuators.

Mobile Phone Operated Dual-tone-multiple-frequency controlled Microcontroller...IOSRJEEE
Dual-tone-multiple-frequency (DTMF) controlled vehicle is a specific idea in automotive whose actions can be controlled by a mobile phone from all over the world using the DTMF signaling. Traditionally wireless controlled vehicles make use of RF (radio frequency) circuits, which have its own disadvantages of restricted operational range, limited frequency range and limited control. Use of mobile phones for robotic controls provides working range as large as the coverage area of the service provider and no interference with other controllers. I can propose a microcontroller based less effort oriented, cost productive hockey ground roller with smooth pitch rolling technique operated from long range distance by using Mobile phone which acts as a DTMF signal controller with GSM technology. Generally the field of play is 91.4 by 55.0 meters with an area of 5,027 square meters for Hockey. According to my proposed work ground authority can be able to operate that roller to roll aforesaid measurement from pavilion without taking any help of ground staff. Combination of DTMF-GSM technology is more controller friendly as it doesn’t interfere with other controllers and can use up to twelve controls. It also has the advantages of robust control and provides working range as large as the coverage area of the service provider.

Project Report on HOME AUTOMATION USING DTMF.
The Project “Home Automation using mobile communication” has different sections such as:
1.Microcontroller
2.DTMF decoder
3. Relays
. This project we propose a unique System for Home automation utilizing Dual Tone Multi Frequency (DTMF) that is paired with a wireless module to provide seamless wireless control over many devices in a house. This user console has many keys, each corresponding to the device that needs to be activated. The encoder encodes the user choice and sends via a GSM transmitter. The GSM receiver receives the modulated signal and demodulates it and the user choice is determined by the DTMF decoder. Based upon this the required appliance is triggered.

5. What is Arduino?
• Arduino is a tool for making computers that can sense and control more of
the physical world than your desktop computer.
• Arduino is an open-source electronics prototyping platform based on
flexible, easy-to-use hardware and software.
• An Arduino board consists of an 8 bit Atmel AVR microcontroller with
complementary components to facilitate programming and incorporation
into other circuits.
7. The chassis needs to hold four motors, circuit and the power supply. It is made
using a wooden plank. The robustness and flexibility of the robot depends on
the chassis. We have used hardboard for chassis.
The wheels are a crucial part of the robot as they must be very precise in
their size for the straight motion of the robot. So, we have used 4 wheels
for main locomotion.
8. MOTORS:
Motors are being used for the locomotion..
While choosing a motor for locomotion, one must keep a few things in
mind. We need to look for motors with low voltages and higher current
ratings. This holds true for unipolar as well as bipolar motors.
9. Ics :-
L293D is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as
current amplifiers since they take a low-current control signal and provide a
higher-current signal. This higher current signal is used to drive the motors.
10. CIRCUIT DIAGRAM
DTMF Controlled ROBOT
DTMF is a signaling system for identifying the keys or better say the number
dialed on a DTMF keypad. The early telephone systems used pulse dialing or loop
disconnect signaling. This was replaced by multi frequency (MF) dialing. DTMF is a
multi frequency tone dialing system used by the push button keypads in
telephone and mobile sets to convey the number or key dialed by the caller.
DTMF has enabled the long distance signaling of dialed numbers in voice
frequency range over telephone lines.
11. DTMF Mobile ROBO is a machine that can be controlled with a mobile. In this
project, the robot is controlled by a mobile phone that makes a call to the mobile
phone attached to the robot. In the course of a call, if any button is pressed, a
tone corresponding to the button pressed is heard at the other end of the call.
This tone is called "Dual Tone Multiple-Frequency" (DTMF) tone. The robot
perceives this DTMF tone with the help of the phone stacked on the robot. The
received tone is processed by the Arduino with the help of DTMF decoder. The
Arduino then transmits the signal to the servo motors & our robot starts moving.
HOW BOT IS WORKING?
In this project 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 multi frequency tone (DTMF), robot receives
this DTMF tone with the help of phone stacked in the robot
The received tone is processed by Arduino with the help of DTMF decoder
MT8870. The decoder decodes the DTMF tone in to its equivalent binary digit and
this binary number is send to the Arduino, the Arduino is preprogrammed to take
a decision for any given input and outputs its decision to motor drivers in order to
drive the motors for forward or backward motion or a turn.
The mobile that makes a call to the mobile phone stacked in the robot acts as a
remote. So this simple robotic project does not require the construction of
receiver and transmitter units.
The version of DTMF used for telephone dialing is known as touch tone .
DTMF assigns a specific frequency (consisting of two separate tones) to each key s
12. that it can easily be identified by the electronic circuit. The signal generated by
the DTMF encoder is the direct al-gebric submission, in real time of the
amplitudes of two sine(cosine) waves of different frequencies, i.e. ,pressing 5 will
send a tone made by adding 1336hz and 770hz to the other end of the mobile.
