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.WHAT IS ROBOTICS:-Robota (Czech) = A worker of forced labor • The word robotics is used to collectivily define a field in engineering that covers the mimicking of various human characteristics • Historical Robots include: 1. Mechanical automata 2. Motor-driven automata 3. Computer-controlled robots
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…Types of Robot:- • Wheeled • Legged • Climbing • FlyingLaws of Robotics:-The term robotics was coined in 1940s by sciencefiction writer Isaac Asimov.
Asimovs 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 & second Law.WHY ROBOTICS IS NEEDED:- Because • Of Speed. • Of It can work hazardous/dangerous environment. • Of perform respective task. • Of Efficiency • Of Accuracy • Of Adaptability
Components of ROBOTS:- • Structure • Power source • Actuation • Sensing • Manipulation • LocomotionStructure:- • 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:- • 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 :- i. DC Motors ii. Stepper Motors iii. Servo MotorsDC Motors :- i. As the name suggests, a motor which uses a DC (Direct Current) power ii. Can run in both directions iii. Speed ControllableStepper Motors:- i. Used for measured rotation ii. Can be held at a particular position of the shaft iii. Ideal for many autonomous robots requiring higher precisionServo Motors :-
i. Used in closed loop control systems in which work is the control variable. ii. 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 itselfACTUATION:- • It is concerned with the motion of the robot. • Robot contains different types of drives:- i. Differential drive ii. Car type iii. Skid steer drive iv. Synchronous drive v. Pivot drive vi. Articulated drive
Industries Using Robotics- • Agriculture • Construction • Transportation: air, ground, rail, space, etc. • Military, surveillance, attack, etc. • Entertainment • Health care • Manufacturing • Mining • Automobile • WarehousesADVANTAGES- • 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:- • Scientists say that it is possible that a robot brain will exist by 2019 . • 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:- • Robots will soon be everywhere, in our home and at work. • When the Singularity happens,robots will be indistinguishable from human beings and some people may become Cyborgs: half man and half machine • They will change the way we live.
