REMOTE OPERATED SPY ROBO PPT
- 2. INTRODUCTION CIRCUIT COMPONENTS BLOCK DIAGRAM CIRCUIT DIAGRAM & DESIGN CONSTRUCTION HOW TO OPERATE?? APPLICATIONS LIMITATIONS SPY ROBOTS
- 3. A remote operated spy robot circuit which can be controlled by using a wireless remote controller. It can capture audio and video information’s from the surroundings and can be sent to a remote station through RF signals. The maximum range is 125 meters. It overcomes the limited range of infrared remote controllers.

- 6. Remote operated spy robot has mainly two sections, one is Remote Control Section used to control the robot and other one is Video Transmission Section used to transmit audio and video information. These two sections are briefly explained below.
- 7. Remote Controlled Section Here HT12E encoder reads the parallel data from the switches and gives this data to the RF transmitter serially. The operating voltage of this encoder is 2.4 to 12V. The RF 434 MHz Transmitter output is up to 8mW at 433.92 MHz frequency. This ASK transmitter accepts both linear and digital inputs and operating voltage is 1.2V to 12V DC. In remote section, SW1 is used to enable the transmission.
- 9. Video Transmission Section In this section, major components are wireless camera, RF receiver and Robot. Wireless CCD Camera The operating voltage of CCD camera is 12V DC. The supply for this camera is taken from the motors battery. The output signals of this camera are in the form of audio and video. These types of cameras are commonly available in the market.
- 11. RF Receiver It ask receiver & receives the serial data transmitted by the transmitter and gives it decoder to convert it to the parallel. This parallel data is given to the L293D motor driver IC to control the robot motors. Here LED D5 indicates the valid transmission.
- 13. Take a hylam sheet with (20cm*15cm) size. Fix two gear motors (12VDC 100rpm) in the hylam sheet by using aluminium pieces and nut bolts as shown in the figure below Fix the ball castor as shown in the figure below.
- 15. Then fix the battery (12VDC 1.2Ah) on the top of the spy robot Connect two motors to the PCB. The PCB is then connected to the battery. Connect the wireless CCD camera to the battery Connect the camera receiver to the TV or computer. Video information’s will thus appear in the screen. Switch on the remote controller and control the spy robot.
- 17. Give the connections as per the circuit diagram. Arrange the wireless CCD camera to the robot. Give the wireless camera receiver connection to the computer or TV. Now switch on the both robot and remote supplies. Control the spy robot using remote. Now you can observe the robot surroundings in your computer or TV.
- 18. This spy robot is used to observe the behaviour of wild animals where human beings cannot reach. Used in army applications to detect the bombs. Used in industries.

- 19. This system does not work for longer distances. This is a theoretical circuit and may require some changes to implement practically.
- 21. Know before you go! The Spy Robots are “throw able” robots, which serve as your "man on the inside" for a broad range of military, police, security, and rescue applications. In any dangerous, hostile, or confined environment, you’ll instantly get critical visual intelligence that can save lives and reduce property damage.
