Introduction
A robot is an electro-mechanical device that can perform autonomous or
preprogrammed tasks. A robot may act under the direct control of a human
(eg. the robotic arm of the space shuttle) or autonomously under the control
of a programmed computer. Robots may be used to perform tasks that are
too dangerous or difficult for humans to implement directly (e.g. nuclear
waste clean up) or may be used to automate repetitive tasks that can be
performed with more precision by a robot than by the employment of a
human (e.g. automobile production.)

2. Abstract:
This project aims at designing a robot, which has freedom of
movement along all the 3 axes and its motion is controlled by means of
wheels. The user can control the movements using a Cellphone from a
remote place. The system is made more useful by introducing artificial
intelligence to it. By artificial intelligence, we mean designing the robot is
such a manner that in situation which require decision making, the robot
identifies the presence of the obstacle, alerts the user and moreover awaits
instruction from the user for the further action. Other condition, which the

3. robot can determine, is presence of fire. I.e., high temperature and presence
of metals in vicinity.
Existing Technique and Proposed Idea:
Although robots exists which can be controlled by a short range
wireless or wired communication only. Today GSM Communication have
become a common thing with the advancement in the communication field.
So we planned to implement the GSM Communication (using cell phone)
for controlling the actions of a Robot.
Working:
A robot is constructed and is connected to a cell phone with associated
electronic circuits. Now the user can dial the no of the cell phone to which
the robot is connected from a remote place using another cell phone. The
electronic circuits will identify the incoming call and connects the call for
the user to communicate with the robot. Now the user can control the
movements by pressing the desired key. For eg 1 – Forward movement,
2 – Reverse, 3 – left etc.
This project is divided into modules for better understanding of the
circuit.The modules include
Mobile phone Control Circuitary
PIC Microcontroller Board
Optocoupler With Stepper Driver Board
Stepper Power Supply Board.
Fire Sensing Unit

4. Smoke Detector
High Temperature Sensing
Mobile Phone Control Circuitary
This Board is used to convert the commands given by the cell phone
to logic level signal and provides the input to the microcontroller.
PIC Microcontroller Board
This is the board which contains PIC Microcontroller Chip as well as
the clock Circuitary, Reset Circuit and Power Supply for the
MicroController.
OptoCoupler With Stepper Driver Board.
The need of Optocoupler is to isolate the Microcontroller Board form
the Stepper Motor to restrict any high voltage to the Microcontroller board.
And this board also contains stepper Driver circuit to amplify the Voltge and
to withstand high current because the pulse coming out from the
Microcontroller is not tough enough to drive the Motor.
Stepper Power Supply.
This board contains the power Supply for the stepper motor and relay
driver.
Flame Sensor
An LDR is used as a flame Sensor. And the output is given to a
Digital input of the Controller. So when the Flame is sensed we can give
alarm +Visual Indication and immediately transfer the Message to a nearby
Fire Station.

5. Temperature Sensor
A Thermistor is used a Temperature Sensor. When Over
Temperature is detected We can stop the movement of the Model. Also we
can give the Visual +Alarm Indication.
Intruder Sensor
An Infrared sensor is used as a intruder detector. So when an intruder
is sensed we can redirect the movement of the Model.
Metal Sensor
A Proximity Metal Detector used as a Bomb detector. So when an
bomb is detecte we can indicate it through the computer.
Smoke Detector:
A smoke detector is used to detect Smoke in an area and provides
alarm output.
All this information is transferred to a remote computer and further to a
remote mobile phone.

7. Reasons For selecting the field:
As of today Robotics is the vast field to explore the things without
human intervention. The word robot is used to refer to a wide range of
machines, the common feature of which is that they are all capable of
movement and can be used to perform physical tasks. Robots take on many
different forms, ranging from humanoid, which mimic the human form and
way of moving, to industrial, whose appearance is dictated by the function
they are to perform. Robots can be grouped generally as mobile robots (eg.
autonomous vehicles), manipulator robots (eg. industrial robots) and self
reconfigurable robots, which can conform themselves to the task at hand.
