INTRODUCTION
 The wireless technology has brought a new meaning to
electronics which makes the indirect connection
between the controller and the equipment.
 Communication using RF is majorly used because RF
transmission is strong , reliable and also used for long
distance communication effectively.
 Motor control through RF communication is a very
interesting application and is widely used in robotics,
automation systems etc. The topic covers the way DC
motors can be driven by using the controls from a
distant place.

RF MODULES
 RF module comprises of an RF Transmitter and an
RF Receiver. The transmitter/receiver (Tx/Rx) pair
operates at a frequency of 434 MHz. An RF transmitter
receives serial data and transmits it wirelessly through
RF through its antenna .
 The transmission occurs at the rate of 1Kbps – 10Kbps.

DC MOTOR
• DC
motors are always preffered
because of its speed, weight,
size, cost...
• you can control the speed of
motor, direction of rotation, also
do encoding of the rotation
made by DC motor interfacing
to the driven IC.
•In the current project the
motion of rover is controlled by
these DC motors of 100RPM and
operate for 9V of DC voltage.
PROGRAMMING TOOL
 ‘Top win’ is a software working as a user friendly
interface for programmer boards from Sunrom Tech.
 It takes in compiled HEX file and loads it to the
hardware.
 Any compiler can be used with it, Assembly or C, as all
of them generate compiled HEX files .
 Baud Rate - 57600, COM x Automatically selected by
window software.
After making the necessary selections, the ‘Burn’
button is clicked as shown below.
APPLICATIONS
 By placing different sensors for monitoring the
surroundings and guiding the people at hazardous
places.
 It can help us in monitoring various parameters like
humidity, temperature, etc.,
 Very importantly even it can be used in the
identification of metals in the landmines. Also human
detection at the risk places can also be done .
FUTURE SCOPE
 In the future , the project can be extended by having
the rover with a material like camouflage which has a
property of hiding itself. Adapting radars to this can
guide the militants .
 The project can be further modified by placing a
highly dense camera for accuracy and zooming. The
manufacturing materials can changed as per the
requirement .
CONCLUSION
 Now-a-days we are a lot depending on wireless dc
motors for various applications . But we can still
produce the better results in new applications , if we
starts working in a different way.
