- 6. 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. 6
- 7. Robotics is science of designing or building an application of robots. Simply ,Robotics may be defines as The Study of Robots. The aim of robotics is to design an efficient robot. Speed Can work in hazardous/dangerous temperature Can do repetitive tasks Can do work with accuracy 7

- 9. The word robot was introduced to the public by Czech writer Karel Capek(1890-1938) in his play R.U.R. (Rossum's Universal Robots), published in 1920. The play begins in a factory that makes artificial people called robots . Capek was reportedly several times a candidate for the Nobel prize for his works . The word "robotics", used to describe this field of study, was coined accidentally by the Russian born , American scientist and science fiction writer, Isaac Asimov(1920-1992) in 1940s. 9
- 10. Asimov also proposed his three "Laws of Robotics. First Law : A robot may not injure a human being, or, through inaction, allow a human being to come to harm, unless this would violate a higher order law Second Law: A robot must obey orders given it by human beings, except where such orders would conflict with a higher order law Third Law : A robot must protect its own existence as long as such protection does not conflict with a higher order law. 10

- 17. Laser range finder Kinect Sonar PTZ Odometer Camera Sensors provide awareness of the environment by sensing things.Sensors are the core of robots.It is the system that alerts the robots 17
- 18. Controller & Processor Arm Effector An end effector is the device at the end of a robotic arm, designed to interact with the environment. End effectors may consist of a gripper or a tool. The gripper can be of two fingers, three fingers or even five fingers Similar to cerebellum. It controls and coordinates the motion of the actuators. The brain of the robot. It calculates the motions and the velocity of the robots joints, etc. Convenient method to allow full movement in 3D more often used in fixed robots due to power & weight even more difficult to control 18

- 22. Mobile robots are of two types. Rolling robots have wheels to move around. They can quickly and easily search. However they are only useful in flat areas. Robots on legs are usually brought in when the terrain is rocky. Most robots have at least 4 legs; usually they have 6 or more. 22
- 23. Autonomous robots are self supporting or in other words self contained. In a way they rely on their own brains. Robots are not only used to explore areas or imitate a human being. Most robots perform repeating tasks without ever moving an inch. Most robots are working in industry settings and are stationary . 23
- 24. A person can guide a robot by remote control. A person can perform difficult and usually dangerous tasks without being at the spot where the tasks are performed. Virtual robots dont exits In real life. Virtual robots are just programs, building blocks of software inside a computer. 24
- 25. Industrial Robots materials handling welding inspection improving productivity Laboratory applications 25
- 26. 26 Educational Robots Robotic kits are used extensively in education. Eg- Robolab,Lego and RoboCup Soccer Domestic Robots 2 typesthey are designed to perform household tasks and modern toys which are programmed to do things like talking, walking and dancing, etc.

- 28. 28 Robotic Applications EXPLORATION Space Missions Robots in the Antarctic Exploring Volcanoes Underwater Exploration MEDICAL SCIENCE Surgical assistant ASSEMBLY- factories Parts- - handling - Assembly - Painting - Surveillance - Security (bomb disposal,etc) - Home help (grass cutting, nursing)
- 29. Going to far away planets. Going far down into the unknown waters and mines where humans would be crushed Giving us information that humans can't get Working at places 24/7 without any salary and food. Plus they don't get bored They can perform tasks faster than humans and much more consistently and accurately Most of them are automatic so they can go around by themselves without any human interference. People can lose jobs in factories It needs a supply of power It needs maintenance to keep it running . It costs money to make or buy a robot 29
