Our robot is used to
extinguish the fire in case of fire Accidents. The movement of the Robotis
controlled by means of stepper motor which is involved in the major application
of Robotics field. It can move in both directions
(Forward and Reverse) Our Robot also consists of a Soleniod which is actuated
to spray the water whenever it senses the Fire.
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.
Fire
Sensing Unit and Extinguisher
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.
Fire Sensing Unit and Extinguisher
The fire
sensor senses the fire and informs the Micocontroller which in turn actuates
the Solenoid to pour the water on the fire to extinguish it.
