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.

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.
CRCUIT DIAGRAM & DESIGN
![Page 7: REMOTE OPERATED SPY ROBO PPT](https://reader034.vdocuments.site/reader034/viewer/2022052213/5872058f1a28ab176b8b6007/html5/thumbnails/7.jpg)
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.

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.

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.

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.

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.

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.

This system does not work for longer distances.
This is a theoretical circuit and may require some
changes to implement practically.

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.
