Introduction To Robotics

  1. 1. Introduction to Robotics <ul><li>Robots have become a subject of great interest nowadays. </li></ul><ul><li>In our imagination, a robot is a machine that looks and acts like a human being. </li></ul><ul><li>Robots are, in fact, defined as man-made mechanical devices that can move by themselves, whose motion must be modeled, planned, sensed, actuated and controlled, and whose motion behaviour can be influenced by “programming”. </li></ul>
  2. 2. History of Robots <ul><li>The acclaimed Czech playwright Karel Capek made the first use of the word ‘robot’, from the Czech word for forced labor or serf. </li></ul><ul><li>The word 'robotics' was first used in Runaround, a short story published in 1942, by Isaac Asimov. </li></ul><ul><li>But it was not until 1956 that a real robot came into existence. </li></ul>Isaac Asimov
  3. 3. The First Robot <ul><li>After the technology explosion during World War II, in 1956, George C. Devol, Norman Schafler and Joseph F. Engelberger and made a serious and commercial effort to produce a robot. </li></ul><ul><li>They started a firm named Unimation and succeeded in building the 1 st robot named Unimate. </li></ul><ul><li>Joseph F. Engelberger is known as the ‘Father of Robotics’ </li></ul>Unimate Puma500 Manipulator
  4. 4. The Unimate <ul><li>It was first used in General Motors. </li></ul><ul><li>It basically to extract die-castings from die casting machines and to perform spot welding on auto bodies, both tasks being particularly hateful jobs for people. </li></ul><ul><li>A variety of other tasks were also performed by robots, such as loading and unloading machine tools. </li></ul><ul><li>The Unimate started a revolution in the robotics industry and many robots of its type were built for doing tiresome jobs for people. </li></ul><ul><li>Robots offer specific benefits to workers and industries. If introduced correctly, industrial robots can improve the quality of life by freeing workers from dirty, boring, dangerous and heavy labor. </li></ul>
  5. 5. Types of Robots <ul><li>The types of robots are: - </li></ul><ul><li>Mobile robots. </li></ul><ul><li>Industrial robots </li></ul><ul><li>Autonomous robots </li></ul><ul><li>Remote-controlled robots. </li></ul><ul><li>Virtual robots. </li></ul>
  6. 6. Mobile Robots <ul><li>Mobile robots are able to move, usually they perform tasks such as searching. </li></ul><ul><li>They are of 2 types: - </li></ul><ul><li>Rolling robots- Rolling robots have wheels to move around.  They can quickly and easily search.  However they are only useful in flat areas. </li></ul><ul><li>Walking robots- 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.  </li></ul>
  7. 7. Industrial Robots <ul><li>Most of these robots perform repeating tasks without ever moving. </li></ul><ul><li>Most robots are working in industries. Especially dull and repeating tasks are suitable for robots.  </li></ul><ul><li>A robot never grows tired; it will perform its duty day and night without ever complaining.  </li></ul>
  8. 8. Autonomous Robots <ul><li>Autonomous robots are self-supporting. </li></ul><ul><li>They run a program that gives them the opportunity to decide on the action to perform depending on their surroundings.  </li></ul><ul><li>At times, these robots even learn new behavior.  They start out with a short routine and adapt this routine to be more successful at the task they perform.  The most successful routine will be repeated . </li></ul>
  9. 9. Remote-controlled Robots <ul><li>In case a robot needs to perform more complicated yet undetermined tasks an autonomous robot is not the right choice. </li></ul><ul><li>  Complicated tasks are still best performed by human beings with real brainpower.  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.  </li></ul>Dante 2, a NASA robot designed to explore volcanoes via remote control.
  10. 10. Virtual Robots <ul><li>Virtual robots don’t exits in real life.  Virtual robots are just programs, building blocks of software inside a computer.  </li></ul><ul><li>A virtual robot can simulate a real robot or just perform a repeating task. </li></ul><ul><li>Search engines use such kind of robots. They search the World Wide Web and send the information to the search engines. </li></ul>
  11. 11. The Future of Robotics <ul><li>To demonstrate advances in research and stimulate scientists, a RoboCup soccer competition is held a few times every year. </li></ul><ul><li>Recognizing teammates, the goals, the ball is a difficult task for the robots. Thus, it becomes a challenge for them. </li></ul><ul><li>Thus, constant advances are being made in robotics and robots are bound to revolutionize Humanity </li></ul>
