WHAT IS A ROBOT??

“A reprogrammable, multifunctional manipulator designed to move

material, parts, tools, or specialized devices through various

programmed motions for the performance of a variety of tasks."

Robot Institute of America, 1979

“Where AI (Artificial Intelligence) meets the real world.”

WHAT IS A HUMANOID?

A humanoid robot is a robot with its overall appearance based on

that of the human body A humanoid is an autonomous robot because

it can adapt to changes in its environment or itself to continue its

goal.

This is the main difference between a humanoid and other robots.

HUMANOID FEATURES

Humanoid features Self maintenance (Self recharging).

Autonomous Learning(learning new abilities without outside

assistance) .

Avoiding harmful situations to people and property

Safe interactions with the environment and human beings.

AN INTRODUCTION TO ASIMO

An Introduction to ASIMO which stands for (Advanced Step In

Innovative Mobility) was developed by the honda motor company in

japan. Asimo now is the most advanced humanoid robot of its kind.

Asimo is the first humanoid that can walk independently and climb

stairs.

It can understand preprogrammed gestures and spoken commands.

Asimo also has hands that can almost replicate the activities of the

human hand.

ASIMO ROBOT

ASIMO is a humanoid robot created by HONDA, standing at 4 feet

3 inches and weighs 54 kgs, the robot resembles a small astronaut

wearing a backpack and can run on two feet at speeds 6 km/hr and

can also react with the enviroment.

ASIMO was created at Honda’s development and research center in

japan. Officially the name is an acronym for “Advanced Step In

Innovative Mobility.

Honda has laid more emphasis on walking as of Feb 2009 there are

more than 100 units of ASIMOs in existence .

ASIMO HUMANOID ROBOTS

ASIMO'S MOTION: WALK LIKE A HUMAN

ASIMO's Motion: Walk Like a Human ASIMO has soft projections

on its feet that play a similar role to the one our toes play when we

walk & absorbs impact on the joints.

ASIMO has 34 degrees of freedom spread over different points of

its body in order to allow it to move freely.

ASIMO also has a speed sensor and a gyroscope sensor mounted on

its body.

They perform the tasks of: sensing the position of ASIMO's body

and the speed at which it is moving relaying adjustments for balance

to the central computer

MOTION CONTINUED…

ASIMO also has floor surface sensors in its feet and six ultrasonic

sensors in its midsection.

These sensors enhance ASIMO's ability to interact with its

environment by detecting objects.

Zero moment point-proper posture while walking is to be achieved

by balancing 3 forces- human impact force, earth’s gravitational

force and ground reaction force.

Varying speeds is achieved by maintaining these 3 forces.

CONTROLLING ASIMO’S POSTURE

To control ASIMO's posture, engineers worked on three areas of

control:

Floor reaction control means that the soles of the feet absorb floor

unevenness while still maintaining a firm stance.

Target ZMP control means that when ASIMO can't stand firmly and

its body begins to fall forward, it maintains position by moving its

upper body in the direction opposite the impending fall. At the same

time, it speeds up its walking to quickly counterbalance the fall.

Foot-planting location control kicks in when the target ZMP control

has been activated. It adjusts the length of the step to regain the right

relationship between the position and speed of the body and the

length of the step.

SMOOTH MOVES

Smooth moves ASIMO uses a technology called "predictive movement control” ASIMO predicts how much it should shift its center of gravity to the inside of the turn and how long that shift should be maintained.

It adjusts any of the following factors in order to maintain the right position: the length of its steps its body position its speed the direction in which it is stepping

ASIMO can now run at speeds up to 3.7 miles per hour . In order to qualify as a true running robot, ASIMO must have both feet off the ground for an instant in each step.

ASIMO manages to be airborne for .08 seconds with each step while running. Without this ability, ASIMO would lose control while airborne, possibly spinning in the air or tripping when landing.

ASIMO’S INTELLIGENCE TECHNOLOGIES

Asimo’s Intelligence Technologies Intelligence technology to

ASIMO which is capable of interpreting the postures and gestures of

humans and moving independently in response.

ASIMO’s ability to interact with humans has advanced

significantly—it can greet approaching people, follow them, move

in the direction they indicate, and even recognize their faces and

address them by name.

THE KEY FEATURES OF THE NEW INTELLIGENCE

TECHNOLOGY

The key features of the new Intelligence Technology:

1. Recognition of moving objects

2. Posture/gesture recognition

3. Environment recognition

4. Sound recognition

5. Face recognition.

1.RECOGNITION OF MOVING OBJECTS

1. Recognition Of Moving Objects Using the visual information

captured by the camera mounted in its head, ASIMO can detect the

movements of multiple objects, assessing distance and direction

Specifically, ASIMO can follow the movements of people with its

camera, follow a person,greet a person when he or she approaches.

2.RECOGNITION OF POSTURES & GESTURES

Based on visual information, ASIMO can interpret the positioning and

movement of a hand, recognizing postures and gestures.

Thus ASIMO can react not only to voice commands, but also to the

natural movements of human beings.

For example, ASIMO can recognize an indicated location and move to

that location (posture recognition); shake a person's hand when a

handshake is offered (posture recognition); respond to a wave by

waving back (gesture recognition).

3.FACE, DISTINGUISHED SOUND &

ENVIRONMENT RECOGNITION

This is able to assess its immediate environment, recognizing the

position of obstacles and avoiding them to prevent collisions.

ASIMO's ability to identify the source of sounds has been improved,

and it can distinguish between voices and other sounds.

ASIMO has the ability to recognize faces, even when ASIMO or the

human being is moving.

For example, ASIMO can: recognize the faces of people which have

been pre-registered, addressing them by name, communicating

messages to them, and guiding them; recognize approximately ten

different people.

CONTROLLING & POWERING ASIMO

Asimo can be controlled by the following ways:-

1.PC

2.Wireless controller

3.Voice Commands

4.Brain machine Interface

Asimo is powered by a rechargeable, 51.8 volt lithium ion (Li-ION) battery that lasts for one hour on a single charge. The battery is stored in ASIMO's backpack and weighs about 13 pounds.

ASIMO's battery takes three hours to fully charge.

APPLICATIONS

PROS AND CONS OF ASIMO

Pros and cons of Asimo :

Pros It can do tedious chores that take up a lot of time.

Help the elderly and disabled Can perform certain tasks that are

dangerous to humans Productivity can increase.

Cons People will fear that ASIMO might take over their job Less

personal communication Fear that robots will take over human

activity very expensive.

CONCLUSION

In my opinion ASIMO is an amazing technological advancement

This will allow people allocate their time in a more productive

manner ASIMO will provide a number of positive contributions to

human beings. Life in the future will probably see these wonderful

machines doing chores in our house….maybe???
