This document describes a robotic vehicle that can be remotely operated and monitored using an Android application. The robot is equipped with a wireless night vision camera that can transmit real-time video to a smartphone or tablet. The remote operation is achieved through a graphical user interface on the Android device. The robot could potentially be used for surveillance or spying in military situations.

2.  The project is designed to develop a robotic
vehicle using android application for remote
operation.
 This robot along with camera can wirelessly
transmit real time video with night vision
capabilities.
 This is kind of robot can be helpful for spying
purpose in war fields

3.  The whole path that the robot traverse is being
seen by the wireless night vision camera that is
placed on robot and accordingly the video
signals are sent by the camera for the direction it
traversed.
 Remote operation is achieved by any smart-
phone/Tablet etc., with Android OS, upon a GUI
(Graphical User Interface) based touch screen
operation.

4.  Android is an open-source operating system
which means that any manufacturer can use it
in their phones free of charge.
 It was built to be truly open. For example, an
application can call upon any of the phone’s
core functionality such as making calls,
sending text messages, or using the camera.

5. Android is built on the open Linux Kernel.
Furthermore, it utilizes a custom virtual
machine that was designed to optimize
memory and hardware resources in a mobile
environment.

6.  An android app is meant for phones with an
android based operating systems. They can be
downloaded from the android app Market
which is pre-loaded on every android phone.
 Blue control APP and Bluetooth Spp APP are
some examples.

7. Very customizable. Open source operating system
is easily changed, hacked, manipulated, and
molded to fit whatever functionality you had in
mind. Found on all platforms for all prices
depending on what hardware and software
version you are interested in. The battery is
usually replaceable.

8. i-OS:
It's not available on all carriers but this is
expanding. The battery is not replaceable
which is why all the i Phone users you
know have it plugged in all the time as the
battery degrades.

10.  The Android platform includes support for the
Bluetooth network stack, which allows a device
to wirelessly exchange data with other
Bluetooth devices.
 The application framework provides access to
the Bluetooth functionality through the
Android Bluetooth APIs.

11.
• Super simple and easy way to interface
using Bluetooth stack.
• 3.3V Device with standard 5V DC Power source.
• Can also support SPI Protocol, pins are made
available.
• Low power consumption, Low cost.
• Has high-performance wireless transceiver system
• Can be used to interface with PC, Mac or Android
phones/tablets.

12.  Generic Default Visibility at Software
side:HC-06 or Linvor
 Default Pairing code is not '0000' but '1234'.
 Please use Baud Rate with 8-N-1
connectivity from other device.
 Works with any microcontroller with Serial
connectivity.

14. • The circuit uses HT 12E, HT 12D encoder
and decoder.
• 433MHz ASK transmitter and receiver is
used for the remote control.

15. • Range in open space(Standard Conditions) :
100 Meters
• RX Receiver Frequency : 433 MHz
• RX Typical Sensitivity : 105 Dbm
• RX Supply Current : 3.5 mA
• RX IF Frequency : 1MHz
• Low Power Consumption
• Easy For Application
• RX Operating Voltage : 5V
• TX Frequency Range : 433.92 MHz
• TX Supply Voltage : 3V ~ 6V
• TX Out Put Power : 4 ~ 12 Dbm

16. • The HT 12E Encoder ICs are series of CMOS
LSIs for Remote Control system applications.
They are capable of Encoding 12 bit of
information which consists of N address bits
and 12-N data bits.
• The HT 12D ICs are series of CMOS LSIs for
remote control system applications.
• This ICs are paired with each other. For proper
operation a pair of encoder/decoder with the
same number of address and data format
should be selected.
• The Decoder receive the serial address and
data from its corresponding decoder,
transmitted by a carrier using an RF
transmission medium and gives output to the
output pins after processing the data.

17. • Wireless camera detects and
scan all the common video
frequencies, usually
somewhere between 50
MHz and 30 GHz, within a
certain radius
• It then allow the user to
monitor what is being
broadcast on those
frequencies, if the signal is
strong enough, the wireless
camera detectors usually
display the images.

18.  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.
 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.

19. • 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.
• If enable 2 and pin number
10 are high leaving pin
number 15 as low then the
motor rotates in forward
direction.

20.  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.
