The term "robot" was first used in 1920 in a play called "R.U.R." Or “ Rossum 's universal robots" by the Czech writer KarelCapek.
The word “Robot ”come s from the word “ Robota ”,meaning ,in Czech”, forced labour, drudgery.

Robot - Mechanical device that performs human tasks, either automatically or by remote control.
A re-programmable, multifunctional, automatic industrial machine designed to replace human in hazardous work. for the performance of a variety of Tasks
Robotics - Study and application of robot technology.
Telerobotics - Robot that is operated remotely.

Asimov proposed three “Laws of Robotics”
Law 1: A robot may not injure a human being or through inaction, allow a human being to come to harm.
Law 2: A robot must obey orders given to it by human beings, except where such orders would conflict with the first law.
Law 3: A robot must protect its own existence as long as such protection does not conflict with the first law.
Laws of Robotics

Industrial Robots – –materials handling –welding –inspection –improving productivity –Laboratory applications
Types of Robots

Mobile Robots- –Robots that move around on legs, tracks or wheels. E g- In 1979 a nuclear accident in the USA caused a leak of radioactive material which led to Production of special robot –whichCan handle the radioactive materials.

Educational Robots – Robotic kitsAre used extensively in education.Eg-Robolab ,Lego andRobo Cup Soccer Domestic Robots–2 types–those designed to perform household task and modern toys which areprogrammed to do things like talking,walking and dancing,etc.

1. Manipulator : Main body of robot (Links, Joints, other structural element of the robot)
2. End Effecter: The part that is connected to the last joint hand) of a manipulator.
3. Actuators: Muscles of the manipulators (servomotor, stepper motor, pneumatic and hydraulic cylinder).
4. Sensors: To collect information about the internal state of the robot or To communicate with the outside environment.
Robot Components

5. Controller: Similar to cerebellum. It controls and coordinates the motion of the actuators
6. Processor: The brain of the robot. It calculates the motions and the velocity of the robot’s joints, etc
7. Software: Operating system, robotic software and the collection of routines.

Sensors provide awareness of the environment by sensing things.Sensors are the core of robots.It is the system that alerts the robots..

In robotics, 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.

Manipulations- Degrees of freedom
◦ independently controllable components of motion Arms:
◦ convenient method to allow full movement in 3D◦ more often used in fixed robots due to power & weight◦ even more difficult to control! due to extra degrees of freedom
Grippers:◦ may be very simple (two rigid arms) to pick up objects◦ may be complex device with fingers on end of an arm◦ probably need feedback to control grip force

Used to do repetitive (boring) actions or jobs
Perform a variety of tasks
Improve in quality
Increase in production
Perform dangerous tasks that humans can’t doRobots assisting the handicapped
Robots do not get sick, they can work 24/7 without complaining

Today we find most robots working for people in industries, factories, warehouses, and laboratories. Robots are useful in many ways. Therefore, having robots helps business owners to be competitive, because robots can do jobs better and faster than humans can.
