What is robot…?A reprogrammable multifunctional

manipulator designed to movie material parts tools or specialized devices through various programmed motions for the performance of a variety task - Robot institute of America

An intelligent robot is a mechanical creature which can function automatically

History Early stages

The notion of putting machines to work can be credited to great thinkers like Aristotle

Westinghouse electrical crop creates two of the first robots that use the electrical motor for entire body motion

1968… shakey build at stanford research institute

Shakey could perform task that required planning route-finding and the rearranging of simple objects.

Our times In 1997 the P1 robot was produced by

Honda which was more like human like

CapabilitiesWalk aroundClimb stairs Pick things Carry thingsPushPosition it self

In 2000 Honda incorporated the P3 technology into its dancing robot ASIMO-(Advanced human robot)

Why humanoids…?Are there any good reasons for doing

research on humanoid robots ? work in dangerous environment Exhaustive and respective taskDivision of labour with humans in

cooperative taskAnthropomorphism EmbodimentInteraction and communication

Anthropomorphism Human have built complex environments

tools and equipments very much adapted to our selves.

Robots with human-like morphology and motion capabilities have a greater potential acting in living environment created for humans Use.

EmbodimentThe form of our bodies is critical to the

representation that we develop and use for both internal through and our language

If we are to build a robot with human like intelligence then it must have a human like body in order to be able to develop similar sorts of representation

The important aspects of being human are interaction and communication with other humans.

Humanoids can communicate in a manner that natural communication modalities of humans Ex- facial expiration body posture gesture direction and voice

If robots has humanoid form then it will be both easy and natural for humans with it in human like way

Who is ASMO..?ASMO is humanoid robot created in 2000

by Honda.

ASMO stands for Advanced step innovative mobility

11Th in the line successive bipedal humanoid model by Honda.

It is the 4th man like humanoid robot

Specifications Weight :- 52 kilogramsRunning speed :- 6Km/hWalking speed while carry objects:-1.6 km/hHeight:- 130 cm Width:-45cmHeight:- 130 cmDepth:- 44 cmContinuous operating time :- 40 min – 1 hrDegrees of freedom :- 34

Why legs for humanoids…?Potentially less weightBetter handling of rough terrainsOnly about a half of the worlds land mass

is accessible by current man built vehiclesMore energyActive suspensionIn order to get support and balance the

whole robot

Why bipeds…?A bipeds robot can be shorter along the

walking direction and can turn around in small areas

Light weightMore efficientEverything must be built to be more

comfortable for use of humanSocial interaction with robots and our

perception

Walking V/s RunningMotion of a legged system is called

walking in all instances at least one leg is supporting the body

If there are instances where no legs are on the ground running

Walking can be statically or dynamically stable

Running is always dynamically stable

Honda dynamic stability controller Keep foot on flat on the ground Estimate the danger of foot roll by

measuring ground reaction forceCarefully designedAdvance robotMulti work force

Recognition of technologyWith 2000 ASIMO model Honda added

many features labeled intelligence technology that enables ASIMO to interact with humans following features are added

Recognition of moving objectPosture/gesture recognitionEnvironment recognition Sound recognitionFace Recognition

Recognition of moving objects ASIMO can detect movement of multiple

objects assessing distance and direction using the visual by capturing camera

Features served by this applicationFollow the movement of peopleFallow a person Proper replay for human

Recognition of postures and gesturesPositioning and movement of a hand

recognition postures and gestures

Can react and directed to both voice commands and natural movements of human being

Recognize hand sakeA person waving at itMovement direction

Environment RecognitionASIMO can recognition the objects and

train the robot to safe guard themselves and human being

Recognizing the hazards of surroundings

Avoid hitting objects when danger comes to human

Distinguishing sounds ASIMO can distinguishing between voice

and other sounds

He can respond to his name,face of people,recognize sounds direction objects image.

Facial recognition ASIMO has the ability to recognize face

even when Human being moving

It can individually recognize approximately 10 different faces once they registered it can respond there name

EX- ASIMO is working as Bartender in America

Conclusion Robots are taking over tasks which are

perform by human being in Oder to reduce risk by accepting challenge and danger

Next 50 years may come as robot era
