This document describes a security-based handheld control bot that uses gesture recognition technology. A camera captures the user's hand gestures which are processed through predefined algorithms in MATLAB to identify the gestures. If a gesture like "forward" is detected, a signal is sent wirelessly to a microcontroller that controls motors on the bot to move forward. This type of gesture-based human-machine interface has applications in assisting disabled individuals and enhancing security and gaming.

3. INTRODUCTION
• In our life, we have a great importance of gestures in our
day to day life.
• So, we thought of using the gesture in some technical
means and finally we agreed to the “Security based
Hand-held Control bot”.
• Basically we will be capturing the image of Gesture we
are doing and then processing it through predefined set
of algorithms written in “MATLAB.”
• We chose Mat lab because it was the best available
means to us for image processing.
• The mat lab takes the gesture performed by the user as
an image and processes it and compares it with the
predefined algorithm for identifying gestures.

4. WHAT IS GESTURE?
•
Interface with computers using gestures
of the human body, typically hand
movements.
•
One way gesture recognition is being
used is to help the physically impaired to
interact with computers, such as
interpreting sign language.
• The gestures of the body are read by a
camera instead of sensors attached to a
device such as a data glove.
• In addition to hand and body
movement,
gesture
recognition
technology also can be used to read
facial and speech expressions (i.e., lip
reading), and eye movements.

5. SOFTWARE NEED
 Matlab
•
Matlab is a basically build for image
processing and our project is also a
good
example
of
an
image
processing project.

Keil Compiler
•
It is Development and Convert the
code into .hex file which load into our
microcontroller.

6. HARDWARE USED
 8051 Microcontroller:• The
P89V51RD2
is
an
8051
microcontroller with 64 KB Flash and
1024 bytes of data RAM
• A key feature of the P89V51RD2 is its X2
mode option
• The design engineer can choose to run
the application with the conventional
8051 clock rate (12 clocks per machine
cycle) or select the X2 mode (6 clocks
per machine cycle) to achieve twicethe
throughput
at
the
same
clock
frequency.

7. HARDWARE USED

CC2500:-
•
It is transreciever which is used
to transmitted or receive the
signal from robot to
commanding device
•
It is controlled to the Robot with
wireless Communication.
•
The CC2500 is2.4Gh
transreciever designed for very
low power wireless application.

8. HARDWARE
• It is motor control IC which
used control the motor of
robot.
• Simultaneously two motor
drive attached to it.
• L293D
bridge
is
a
dual
Hmotor
driver
integrated circuit (IC).
• Motor drivers act as current
amplifiers since they take a
low-current control signal
and
provide
a
higher-
current signal.

9. WORKING
•
First the camera captures the image of the hand
gesture.
•
It processes the image with predefined algorithms
Writing mat lab.
•
If the gesture is found then it will serially send the data
signal to the computer. ex: forward -'f'.
•
The transmitter then encodes the data received serially
and sends it to the receiver.
•
The microcontroller then receives the signal through the
receiver and compares it with prewritten set of codes.
 For example:•
If f is received then the microcontroller gives signal to
L293D motor driver IC in such a way that the motor
connected to it goes into forward direction.

10. FEATURES
• It is easy to use.
• Person to do anything to anywhere
without any hard work due to using
hand gesture technology.
• Advance using in future.
• Person can do physical gesture to
digital world.
• It is applicable for the person who
can’t talk, they can do only hand
tricks to communicate.

11. APPLICATIONS
• Very Effective and help
to the handicap people
• Useful to Military and
Higher Security bases
• Gaming Zone just Like
Play Stations, XBOX
• Controlling The Car,
Airplane

12. CONCLUSION
• Here we are used in single
hand gesture instead of whole
body movement like driving a
car.
• We proposed a fast and
simple algorithm for hand
gesture
recognition
for
controlling robot.
• This
technology
will
save
humans physical energy.
• In our system of gesture
controlled robots, we have
only
considered
a
limited
number of gestures
