Transcript of War field spying robot

  • 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

  • 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.

  • 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 phones core functionality such as making calls, sending text messages, or using the camera.

  • 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.

  • 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.

  • 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.


  • 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.

  • 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.

  • Super simple and easy way to interface usingBluetoothstack.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 systemCan be used to interface with PC, Mac or Android phones/tablets.

  • Generic Default Visibility at Software side:HC-06 or LinvorDefault 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.

  • +5V


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

  • 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 MHzTX Supply Voltage : 3V ~ 6VTX Out Put Power : 4 ~ 12 Dbm

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
