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.)
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.
Proposed
Idea:
A robot is designed and constructed with
associated electronic circuits to move into an unknown location and transport
the details of that unknown area to a home place. The Robot will have inbuilt sensors and
cameras to achive this.
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 robot can determine, is presence of
fire. I.e., high temperature and presence of metals in vicinity.
This project is divided into modules for
better understanding of the circuit.The modules include
PIC Microcontroller Board
Optocoupler With Stepper Driver Board
Stepper Power Supply Board.
Humidity Sensor
Gas Sensor
Intruder Sensor
Fire Sensing Unit
RF Transmitter and RF Receiver
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.
Humidity
Sensor and Gas Sensor:
Using this sensor, the corresponding
parameters are obtained and sent to a home place
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.
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.
RF
Transmitter and Receiver:
This is the wireless media thro which
the robot sends information to the home place
