Introduction


There is a wide range of use of robot like in restaurant,
in spying; in medical. It can be used in the field of
surveillance.



Now a days robots are highly used in military such as
bomb detection, terrorist identification. Some
intelligent robots are used even in wars also.



Self
-
maintenance



Autonomous learning



Avoiding harmful situations to people,


property, and itself



Safe interacting with human beings and the


environment


Capacities of a humanoid robot


The rise of robot police


USA:



Uses in
bomb disposal



Police and SWAT (Special Weapons And Tactics) teams
using robots for a greater variety of dangerous tasks


China:



police robots for use at the Beijing Olympics in 2008.



Some robots are developed such that citizens are directly
connected with police robots.


Japan:



Used in patrolling shopping centres to monitor
unauthorised access.

Sensors

Touch




In 2009, scientists developed a prosthetic hand, called
Smart Hand, which functions like a real one, allowing
patients to write with it, play piano and perform other fine
movements.




The prosthesis has sensors which enable the patient to
sense real feeling in its fingertips.


Vision



Computer vision systems rely on image sensors which detect
electromagnetic radiation which is typically in the form of either
visible light or infra
-
red light.




The process by which light propagates and reflects off surfaces
is based on optics.




Sophisticated image sensors even require quantum mechanics to
provide a complete understanding of the image formation process.


Types of Sensors

1.
Proprioceptive sensors


2.
Exteroceptive sensors

Proprioceptive sensors



Proprioceptive sensors sense the position, the orientation and the speed of the
humanoid's body and joints.




Humanoid robots use accelerometers to measure the acceleration, tilt sensors
to measure inclination

Exteroceptive sensors



Exteroceptive sensors give the robot information about the
surrounding environment.




Proximity sensors are used to measure the relative distance
(range) between the sensor and objects in the environment.




Tactile sensors also provide information about forces and
torques transferred between the robot and other objects.

Actuators




Actuators are the motors responsible for motion in the
robot
.


Types:





Electric



Pneumatic



Hydraulic



Piezoelectric or ultrasonic



Hydraulic

and

electric

actuators

have

a

very

rigid

behavior

and

can

only

be

made

to

act

in

a

compliant

manner

through

the

use

of

relatively

complex

feedback

control

strategies
.



Piezoelectric

actuators

generate

a

small

movement

with

a

high

force

capability

when

voltage

is

applied
.



Ultrasonic

actuators

are

designed

to

produce

movements

in

a

micrometer

order

at

ultrasonic

frequencies

(over

20

kHz)
.



Pneumatic

actuators

operate

on

the

basis

of

gas

compressibility
.


Bimanual movements



Bimanual

movements

in

general

form

a

large

subset

of

hand

movements

in

which

both

hands

move

simultaneously

in

order

to

do

a

task

or

imply

a

meaning
.




Scientists

at

Dublin

City

University

have

researched

a

subset

of

human

movements

called

bimanual

movements




Understanding

bimanual

movements

requires

not

only

computer

vision

and

pattern

recognition

techniques

but

also

neuroscientific

studies
.



Bimanual

movement

includes

three

fundamental

components
.




Low
-
level

image

processing

to

deal

with

sensory

data,

intelligent

hand

tracking

to

recognize

the

left

hand

from

the

right

hand,

and

machine

learning

for

understanding

the

movements
.

Components Assembled in robot

WEB CAM:




Web cam will be mounted on the top of the robot and


it is free to rotate in 360 degrees in any direction.




Webcams typically include a lens, an image sensor, and some support


electronics.


METAL DETECTOR:





Metal detector is mounted on the lower part of robot.




It can detect all the guns and other unwanted metals used by the terrorist
in the process of hostages etc.


Conclusion



It

decreases

the

human

effort

and

carries

their

job

in

very

best

manner
.




The

development

of

police

robotics

would

change

the

nature

of

society

and

the

way

humans

conduct

their

lives
.





It

may

be

that

with

advanced

technological

crimes,

more

dangerous

armed

criminal

gangs,

massively

increased

terrorist

and

some

future

horrors

that

we

cannot

foresee,

society

will

be

prepared

to

concede

much

of

its

current

liberty

and

privacy
.
