4. INTRODUCTION:
• The robot is controlled through an Android
application device where in a user can enter
the commands to the Android application.
• Android phone as a remote for controlling
robot.
• The robot in this project can be controlled in
all four directions.

5. EARLIER TECHNOLOGY
• Robot is controlled by a wire used as a
communication channel.
• The distance of robot was based on the length
of the Cable.
• Only Single user can Access over it.
• The Remote was always attached to robot if
any problem with the remote the whole
Robot
cannot work.

12. MOTOR DRIVER:
It is a dual H-Bridge Motor driver integrated
ckt .Act as current amplifiers.
They force Low current control signal &
provide a higher current signal output.
It can drive the motor in both forward and
reverse direction.
Operating voltage of 5V to 36V.
Max output is 1.2Ampere.

16. WORKING:
• When the user press the commands in the
android phone.
• Bluetooth transfer data of specific command
to the receiver.
• The receiver receives and given to controller
and process to required data for driving the
motors.

17. ADVANTAGES:
• It can be controlled wireless in the range of 10
metres(30ft).
• Low cost.
• It can carry light loads.

18. APPLICATIONS:
• The robot is small in size so can be used for
spying.
• With few additions and modifications, this
robot can be used in the borders for detecting
and disposing hidden land mines.
• The robot can be used for reconnaissance or
surveillance.

19. FUTURE DEVELOPMENT:
• We are planning to Increase Operating range
using WI-FI and DTMF technology.
• Trying to Implement Robot Intelligence using
sensors(eg.. IR ,Metal Detector.etc).
• We can implement wireless camera to find the
exact location of robot.
