fiction movies have depicted robots as very sophisticated machines built by humans to perform complex operations‚ to work with humans in safe critical missions‚ in hostile environments‚ or more often to pilot and control spaceships in galactic travels. At the same time‚ however‚ intelligent robots have also been depicted as dangerous machines‚ capable of working against man through wicked plans. In the Terminator the view of the future is even more catastrophic: robots will become intelligent and

Although these machines do not yet exist‚ some believe that their development is imminent and steps should be taken to ban them now. Should “Killer Robots” be banned ? Killer robots have really become a concern for people nowadays. What is a killer robot? What will happen if they really exist? What will happen to humanity? “A killer robot is a fully autonomous weapon that can select and engage targets without

Robots and Artificial Intelligence Artificial intelligence (AI) is arguably the most exciting field in robotics. It’s certainly the most controversial: Everybody agrees that a robot can work in an …………………...........‚ but there’s no consensus on whether a robot can ever be intelligent. Like the term "robot" itself‚ artificial intelligence is hard to define. Ultimate AI would be a recreation of the human thought process - a man-made machine with our intellectual abilities.

Isaac Asimov’s The Robots of Dawn is an enjoyable read‚ showing many aspects of Asimov’s style and themes. It follows the format of a standard detective novel‚ but with many of Asimov’s characteristic science fiction elements such as interstellar travel‚ flying cars‚ and robots. Two major elements of Asimov’s style are very noticeable in this book: simplicity and dialogue. Despite the technology introduced and the length of the story‚ it was never confusing‚ nor would a reader ever be lost. Asimov’s

The study of robot kinematics‚ require a unified methodology to identify the variables of a robot’s or manipulator’s joints and links. Co-ordinate Frames Robotic kinematics depends on the use of right handed cartesian frames of reference. Manipulator Geometry A manipulator consists of two types of joints‚ connected by a link. Link A link is a solid mechanical structure which connects two joints. The main purpose of a link is to maintain a fixed relationship between the joints at

Descartes is totally right to be suspicious about ’the given’ before accepting it as the establishment of learning‚ however‚ in the meantime‚ it is not the bravest thought to be distrustful about everything. Throughout first Meditation‚ Descartes disposes of all his past obtained opinion‚ which from his sense is highly dubious. (Descartes‚ Meditations I‚ pg.1‚para. 1) Accordingly‚ he chooses to rebuild his insight from a specific ground and totally believe in things that are indubitable. (Descartes

Latin "Cogito‚ ergo sum" [I think‚ therefore I am] The first piece of Descartes Meditation‚ Descartes attempts to review the beliefs he has been taught in order to establish truth in science. He forms a sceptical belief or hypotheses about everything in the physical world. As a result he suspends his judgement on his previously held beliefs. In the second Meditation‚ Descartes expands theory on the nature of human mind’‚ Descartes questions his identity‚ the eternal I’‚ and introduces a theory

Similarly‚ all three texts share a sub genre of dystopia. Originally derived from the dangers of technology‚ within these texts themes of social class and the flaws of humans are brought up. Social class is clearly a theme portrayed in these texts. Firstly I Robot portrays the robots serving humans as underlings‚ hence

similarity between the movie The Matrix‚ the cave analogy of Plato‚ and Descartes’ Meditation‚ is that all of these works doubt the reality of the world around us and call into question the validity of our sense perceptions. “Let us suppose‚” says Descartes‚ “that we are dreaming‚ and that all these particulars – namely‚ the opening of the eyes‚ the motion of the head‚ the forth-putting of the hands – are merely illusions” (Descartes‚ 1641‚ Meditations on First Philosophy).
