 On
board
mobile phone with camera which feeds live
The
scenario
video to the person who is controlling through 3G video
calling
Need facility.
for the project
 The locomotion of the robot are controlled by another
mobile phone at the controller’s end using DTMF signals.
 The robot can traverse through all the rough terrains and
capability of climbing the steps.
 The robot is equipped with a gun.
 The robot has night vision (IR), also a flash light
 The robot is equipped with a small arm
 The robot has metal detector.
 The robot can avoid obstacles and propagate
autonomously using IR sensors.

DESCRIPTION OF BLOCK DIAGRAM

DTMF decoder
Dual Tone Multi Frequency
 Conversion of analog tones into digital equivalent

DESCRIPTION OF BLOCK DIAGRAM

ATMEL’s 8051 microcontroller
This is the most microcontroller used for general
purpose
 Easily understandable
internal structure and block
diagram
 Flexibility in programming

DESCRIPTION OF BLOCK DIAGRAM

The L293D motor driver
Micro-controller cannot be directly connected
to motor
 Has dual H-bridges

DESCRIPTION OF BLOCK DIAGRAM

Stepper motor
Used to pan the mobile phone’s camera around.
 Stepwise panning for greater detail.
 It is an electromagnetic actuator
 Every time it receives a digital pulse it rotates in
specific number of degrees in rotation.

DESCRIPTION OF BLOCK DIAGRAM

Gun
Relay is used
 Fires when the designated key is pressed


Robotic Arm
Has two degrees of freedom
 Used for cutting wires during bomb diffusion.


Metal detector
Detects landmines
 Sends pulses to the micro-controller
 Which in turn steps the robot back

DESCRIPTION OF BLOCK DIAGRAM

IR proximity sensors
Sharp GP2D12 distance sensors used
 It is capable of measuring the distance between itself
and an object that is within a distance range of 10cm
(~4") to 80cm (~30").

HIGHLIGHTS
Mobile controlled
 3G live video

International Mobile Telecommunications-2000
(IMT-2000).
 Supports video and voice calls
 Very high data rate (up to 14.0 MB/s on the downlink
and 5.8 MB/s on the up link.)


Step climbing ability

Can traverse through any rugged environment
PROCESS OF OPERATION
Video call initiated from the controllers 3G
mobile phone.
 Video call picked up automatically by the 3G
mobile phone present at the robot’s end.
 The controller receives live video from the robot’s
3G mobile phone
 The controller presses the keys in his mobile
which inturn moves the robot present at the
remote place
 All the locomotion controls and arm controls etc.
are incorporated compactly into the keys 0-9,*,#.

CONCLUSION
Idea of mobile controlling and real time video
feed.
 Inclusion of all the controls and supplementary
controls in the available keys of the mobile.
 Indigenously made body and structure.
 Can explore any environment and curb terrorist
activities to a considerable extent and save many
precious lives.
