Voice Recognition Vehicle using bluetooth module

Construction:                                                                                   The Voice Recognition Vehicle project requires following components.                                                1. power supply from lead acid battery.                                                                                                    2. two gear motors (each are rated at 100-150 rpm or Torque motor)                                                      3. L clamps                                                                                                                                                4. Dummy Wheels                                                                                                                                      5. Bluetooth Module HC-05 and                                                                                                                6. Motor driver IC ( L293d )                                                                                                                      7. Arduino Uno Board.                                                                                                                              Power Supply :                                                                                                                             Here we have 12 volt battery as a power source. By using this, we can able to run two equally rated motor as per the given operation. We know battery have charging and discharging. Discharging of battery can be done by giving the load across the battery (here we use motors as load). But charging is only possible by connecting the another external source across the battery.                                         Just Assume EB (Electricity Board) as a source to battery. But in India, AC generation is more preferred than the DC generation due to its maintainance and fuel cost and less efficiency. So AC supply is taken as a source to battery. But AC cannot be stored in DC battery.                                          In India, Most of the residential loads are having 250 volt supply. So we need to reduce voltage level from 250 volt to 12 volt by using Stepdown Transformer.  Then AC supply will be converted into DC supply by providing bridge rectifier circuit along with capacitor for filtering purpose which is in the range upto 1 farad.

                                                                                                                                                                                                                                                                                                                                        Two Gear Motors :                                                                           Two gears motors are used in this project at the back side of the vehicle and front wheels are dummy wheels . if necessary we can use four gear motors for four wheels . Motors each will be rated in 100 - 150 rpm or it is otherwise called as Torque motor. These type of motors produces high torque and low speed for given input. Consider we have used two motors on the back side of the vehicle and front wheels are dummy wheels. The operation of these wheels is given below. 

                                                     Bluetooth Module :                                                                              Bluetooth module "HC-05" or "HC-06" is used to connect arduino and motors wirelessly.                                

                                                                                                                                                                     Here we have used HC-05 module type. As shown in second figure, the HC-05 bluetooth module is working n 26 MHz , LED indication which is used to indicate whether the device is on or off . And also indicates whether the module is connected with motor through arduino. In Bluetooth Module , the following components had used. They are,                                                                                        1.8 MB Flash Memory                                                                                                                         
2.5V - 3.3V power source from battery or from arduino

3.CSR Bluetooth Radio                                                                                                                        4.Antenna   etc.                                                                                                                                           The price of this device is Rs.300/- to Rs.500/- in India. Based on the seller and transportation charges, price of the device may vary.  Online product buying not advisable.                                                                                                                                                                                                            Motor driver IC :                                                                               Motor driver IC is used to control the current driven by the motor. Because it will may damage the equipments.                                                                                                                                                                   

                     

   

This is the pin diagram of L293D motor driver IC. It can able to control upto four motors at the same time. if necessary, more than 4 motors can also controlled by the upgraded version of this IC. But this becomes more complex in circuit design and efficiency may get reduced.

Some Important Definitions

Alloy:-
           A metal produced by the combination of two or more metallic elements, usually to achieve greater strength or resistance to corrosion.

Atom:-
         The basic unit of a chemical element, made up of varying numbers of protons, electrons and neutrons.

Kerosene:-
        Originally a trade name for a lamp oil, the term is now generic and refers to a combustible hydrocarbon liquid used to propel jet engines  and fuel domestic heating.  Usually referred to as "paraffin" in the United Kingdom and South Africa.

Radio Activity:-
           The emission of ionizing  radiation of particles from an unstable atomic nucleus.

Ultraviolet:-
          A form of electromagnetic radiation in the form of light with shorter wavelengths than X-rays.  It is invisible to the human eye but just beyond violet in the color spectrum.  A certain amount of ultraviolet light is needed by the human body to stimulate the production of Vitamin D, though too much causes sunburn.

Volt:-
        A measure of the force of electricity, named for Alessandro Volta, the Italian Physicist who developed the first electric cell in 1800.

Watt:-
         A measure of the rate of energy converted by an appliance: for example, the electrical energy that a light bulb converts into light.  Named for James Watt, the nineteenth-century inventor of the steam engine. 

RADAR:-
          "Radar" is an acronym for Radio Detection and Ranging.  It helps to detect the objects and its distance from the beginning object by the help of electromagnetic waves.  For example: the submarine uses these Radar signals to find the cleared path or detecting objects under the water surface.

DNA:-
        Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic coding for all living organisms.  DNA usually exists as a pair of DNA molecules twisted together in a double helix.

Infra Red:-(IR radiation)
          Electromagnetic radiation that has a wavelength just greater than that of the red end of the visible light spectrum.  It is emitted by heated objects and can be picked up by infrared cameras.

History of E mail

In 1969 a company called Bolt Barenek and Newman won the contract to develop a communication network called ARPANET that would enable scientists and researchers to use each other's computer facilities.  During its development, an engineer named Roy Tomlinson started to experiment with the coding of two programs.  SNDMSG allowed members of the same network to exchange messages among one another,whereas CPYNET allowed file transfers to occur between two separate networks.  It occurred to Tomlinson that by combining the two he could create a system that would make message transfer possible between different user s of independent networks.
