INTRODUCTION v 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 . v ASIMO was created at Honda ’ s development and research center in japan . v Officially the name is an acronym for “ Advanced Step In Innovative Mobility . v The name “ ASI ” in Japanese means legs , so Honda has laid more emphasis on walking v As of Feb 2009 there are more than 100 units of ASIMOs in existence .

what is a humanoid?

Humanoid vA

humanoid robot is a robot with its overall appearance based on that of the human body



humanoid is an autonomous robot because it can adapt to changes in its enviroment or itself to continue its goal.This is the main difference between a humanoid and other robots.

Humanoid features 1. Self maintenance (Self recharging) 2. Autonomous Learning(learning new abilities without outside assistance) 3. Avoiding harmful situations to people and property 4. Safe interactions with the enviroment and human beings

Introduction

to ASIMO

v Asimo which stands for (Advanced Step In Innovative Mobility) was developed by the honda motor company in japan v Asimo now is the most advanced humanoid robot of its kind. v Asimo is the first humanoid that can walk independently and climb stairs. v It can understand preprogrammed gestures and spoken commands. v Asimoalso has hands that can almost replicate the activities of the human hand.

ASIMO's Motion : Walk Like a Human v 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. v 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

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 . To accomplish the job our muscles and skin do in sensing muscle power, pressure and joint angles, ASIMO has both joint-angle sensors and a sixaxis force sensor. 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

Controling 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 



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

Smooth moves continued… v 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. v ASIMO’s torso has a degree of freedom to aid in bending and twisting so that the robot could adjust its posture while airborne. Without this ability, ASIMO would lose control while airborne, possibly spinning in the air or tripping when landing. 

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: 

1. Recognition of moving objects 2. Posture/gesture recognition 3. Environment recognition 4. Sound recognition 5. Face recognition.

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 ASIMO 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: Ø recognize the faces of people which have  been pre-registered, addressing them  by name, communicating messages to  them, and guiding them; Ø 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

Brain Machine Interface

Charging Asimo 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.  Users can charge the battery onboard ASIMO through a power connection or remove the backpack to charge separately  Asimo also has the ability to automatically find its charging station and charge itself 
