Queries WORLD OF ROBOTS : WORLD OF ROBOTS WHAT IS ROBOTICS : WHAT IS ROBOTICS THE WORD ROBOTICS IS USED TO COLLECTIVILY DEFINE A FIELD IN ENGINEERING THAT COVERS THE MIMICKING OF VARIOUS HUMAN CHARACTERISTICS
SOUND CONCEPTS IN MANY ENGINEERING DISCIPLINES IS NEEDED FOR WORKING IN THIS FIELD
IT FIND ITS USES IN ALL ASPECTS OF OUR LIFE What a Robot can mean? : What a Robot can mean? An automatic industrial machine replacing the human in hazardous work.
An automatic mobile sweeper machine at a modern home.
An automatic toy car for a child to play with.
A machine removing mines in a war field all by itself and many more… ROBOTICS : ROBOTICS It is a field of Engineering that covers the mimicking of human behavior.
Robotics includes the knowledge of Mechanical, Electronics, Electrical & Computer Science Engineering. Laws of Robotics : Laws of Robotics The term robotics was coined in the 1940s by science fiction writer Isaac Asimov.
Asimov's Laws of Robotics:
A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
A robot must obey the orders given it by human beings except where such order would conflict with the First Law.
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. WHY ROBOTICS ? : WHY ROBOTICS ? Speed.
It can work hazardous/dangerous
To perform repetitive task.
Adaptability Types of Robot : Types of Robot Wheeled
Flying Components of ROBOTS : Components of ROBOTS Structure
Locomotion Structure : Structure The structure of a robot is usually mostly mechanical and can be called a kinematic chain.
The chain is formed of links (its bones), actuators (its muscles), and joints which can allow one or more degrees of freedom. Power Supply : Power Supply Suitable power supply is needed to run the motors and associated circuitry
Typical power requirement ranges from 3V to 24V DC
220V AC supply must be modified to suit the needs of our machine
Batteries can also be used to run robots
Robots are driven by different motors :-
Servo Motors Slide 16: DC Motors
As the name suggests, a motor which uses a DC (Direct Current) power
Can run in both directions
Speed Controllable Slide 17: Stepper Motors
Used for measured rotation
Can be held at a particular position of the shaft
Ideal for many autonomous robots requiring higher precision Slide 18: Servo Motors :
Used in closed loop control systems in which work is the control variable.
An integral feedback device (resolver) or devices (encoder and tachometer) are either incorporated within the servo motor or are remotely mounted, often on the load itself ACTUATION : ACTUATION Actuators are the "muscles" of a robot, the parts which convert stored energy into movement.
The most popular actuators are electric motors. MANIPULATION : MANIPULATION Robots which must work in the real world require some way to manipulate objects; pick up, modify, destroy, or otherwise have an effect.
Thus the 'hands' of a robot are often referred to as end effectors, while the arm is referred to as a manipulator.
Some manipulators are:
General purpose effectors LOCOMOTION : LOCOMOTION It is concerned with the motion of the robot.
Robot contains different types of drives:-
Skid steer drive
Articulated drive ADVANTAGES : ADVANTAGES Revolution in Medical science and Health care systems.
New & wide scope in Education & Training.
A good help in Nuclear industry.
Used tremendously in Sports activities.
Play the role of an efficient assistance in Research and Development sciences.
Can very well handle household business. FUTURE PROSPECTS : FUTURE PROSPECTS Scientists say that it is possible that a robot brain will exist by 2019 .
Vernor Vinge has suggested that a moment may come when computers and robots are smarter than humans.
In 2009, some robots acquired various forms of semi-autonomy, including being able to find power sources on their own.
The Association for the Advancement of Artificial Intelligence has researched on this problem. CONCLUSION : CONCLUSION Thank you : Thank you
