Robotics is the study and application of robot technology. The term "robot" was first coined in 1920 and comes from the Czech word for forced labor. There are several types of robots including industrial robots used in manufacturing, mobile robots that can move autonomously, educational robots used in classrooms, and domestic robots for household tasks. The main components of a robot include its manipulator or rover body, end effectors for interacting with the environment, actuators that provide movement, sensors for awareness of surroundings, a controller for coordination, and software for operation. Robots are used for a variety of purposes like dangerous, repetitive, or impossible tasks that can assist or replace humans.
i used this presentation in my ICT project and i made the video that is in slide 5. it is on youtube and its URL ''http://www.youtube.com/watch?v=pRQmRPnUTHQ''. please like this video on youtube
Definition and origin of robotics – different types of robotics – various generations of robots – degrees of freedom – Asimov’s laws of robotics – dynamic stabilization of robots
The advent of Mobile Robotics changed the definition of robotics and brought in some very interesting technologies paving the way for cutting edge sciences like AI, Behaviour Based Systems, etc

Robotics is science of designing or building an application of robots. Simply ,Robotics may be defined as “The Study of Robots”. The aim of robotics is to design an efficient robot.
Robotics | Introduction. Robotics is a branch of engineering and science that includes electronics engineering, mechanical engineering and computer science and so on. This branch deals with the design, construction, use to control robots, sensory feedback and information processing.
A presentation about how the Robotics technology comes in the market and what is the history behind it, including various types of sensors, controllers etc. What is the application of this new technology in this tech era?
This presentation is about Robotics Technology. In this presentation, you know about the history of robots, types of robots, advanced robotics technology, application of robots, advantage dis advantage of robots.

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

4. Robotics Terminology
Robot - Mechanical device that performs
human tasks, either automatically or by remote
control.
Robotics - Study and application of robot
technology.
Telerobotics - Robot that is operated remotely.

5. Definition
What is the Defination of 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.

6. Laws of Robotics
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.

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

10. Types of Robots
Educational Robots – Robotic kits
Are used extensively in education.
Eg-Robolab,Lego and
RoboCup Soccer
Domestic Robots–2 types–those
designed to perform household tasks
and modern toys which are
programmed to do things like talking,
walking and dancing,etc.

12. Robot Components
1. Manipulator or Rover: 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.
12
13. 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.

14. SENSORS
Sensors provide awareness of the environment
by sensing things.Sensors are the core of robots.It
is the system that alerts the robots..
Sensing can be in different forms like-
• Light
• Sound
• Heat
• Chemicals
• Force
• Object proximity
• Physical orientation/position
• Magnetic & Electric Fields
• Resistance 14
15. End Effectors
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.
12
18. Actuators…
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
18
19. Degrees of Freedom
Each plane in which a robot can maneuver.
• ROTATE BASE OF ARM
• PIVOT BASE OF ARM
• BEND ELBOW
• WRIST UP AND DOWN
• WRIST LEFT AND RIGHT
• ROTATE WRIST

21. The Purpose of Robots
Robots are also used for the following tasks:
• Dirty Tasks
• Repetitive tasks
• Dangerous tasks
• Impossible tasks
• Robots assisting the handicapped
• Can operate equipments at much higher
precision than humans.
• Cheaper on a long term basis. 21
22. Robotic Applications
