Motor Driver L293D
  • 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.

Motor Driver L293D
  • L293D contains two inbuilt H-bridge driver
    circuits.
  • In its common mode of operation, two DC motors
    can be driven simultaneously, both in forward and
    reverse direction.

Operation of Motor Driver
  • L293D has 2 set of arrangements where one set
    has input 1, input 2, output 1 and output 2
    and other set has input 3, input 4, output 3 and
    output 4, according to block diagram if pin no 2
    7 are high then pin no 3 6 are also high.
  • If enable 1 and pin number 2 are high leaving
    pin number 7 as low then the motor rotates in
    forward direction.

Operation of Motor Driver
  • If enable 2 and pin number 10 are high leaving
    pin number 15 as low then the motor rotates in
    forward direction.
  • If enable 1 and pin number 2 are low leaving pin
    number 7 as high then the motor rotates in
    reverse direction.
  • If enable 2 and pin number 15 are high leaving
    pin number 10 as low then the motor rotates in
    forward direction.

Designing the Robot
The robotic vehicle consists of the following
units
  • A rectangular base to support the whole robot
    structure, attached to two wheels for
    motion.
  • A couple of DC motors to provide required
    movement to the robot.
  • A control unit consisting of an RF receiver which
    receives command signals from a
    transmitter unit to control the engine driver and
    control the motors accordingly.
  • A metal detector circuit along with a buzzer
    alarm which triggered once the metal
    detected.

Designing the Robot
  • Industrial Fire Fighting
  • Most of the industries are faced fire accidents
    problems like gas, petrol, nuclear power plants,
    chemical industries huge amount of damage.
  • And more number of peoples is dead near
    surrounding areas.
  • This robot has the strength to carry a fire
    around inside burning area to supply unlimited
    water.

Designing the Robot
  • Forest Fire Fighting
  • Forest Fires is very dangers.
  • It can be a short time burning large amount of
    forest area.
  • Even city fire departments have to deals with
    forest fires in the area surrounding city.

Working Principle
  • The project uses HT12E Encoder which converts 4
    bit data to serial output which is then fed to
    the RF module.
  • For transmitting the same to be received by the
    receiver RF module the output of which is fed to
    HT12D the serial decoder I.
  • The output of which is fed to controller.
  • The transmitting end MC is connected to a set of
    pushbutton.

25
Fire Fighting Robot Remotely Operated by Android
Applications
Working Principle
  • Thus while a particular button is pressed the
    program executed delivers corresponding 4-bit
    data which are then transmitted serially at port
    1.
  • The data so received at the receiver end of port
    1 operates the motor through motor driver IC
    L293D as required being interfaced from the
    Microcontroller output port 2.
  • The transmitter is powered by a 6v battery in
    series with a silicon diode to finally develop
    required voltage for microcontroller circuit.

26
Fire Fighting Robot Remotely Operated by Android
Applications
Working Principle
  • The receiver is powered by a 12v battery in
    series with a silicon diode to protect the
    circuits from accidental reverse battery
    connection.
  • 5V DC out of the 12V available from regulator IC
    7805 is fed to the controller, decoder, the motor
    driver IC L293D pin 8 for operation of the motor.
  • The receiving unit uses one more motor driver IC
    L293D for driving one DC Motor for arm operation
    with a boom mounted on its shaft.

http//www.edgefxkits.com/
27
Fire Fighting Robot Remotely Operated by Android
Applications
Working Principle
  • At the end of the shaft a nozzle is connected to
    a water tanks mounted water pump which is powered
    from NO contacts of a relay that is driven by
    transistor Q1 from the output of MC pin 15.
  • Thus in the event of a fire the robotic vehicle
    is moved over to the location by operating the
    left, right, forward backward button etc.
  • After it reaches the site the nozzle mounted
    motor takes position through the water on the
    fire from the water tank mounted DC pump actuated
    by the relay RL1.
  • Thus the fire can be extinguished.
