  1. Robots and Computer Science Dr. Dakai Zhu Department of Computer Science, UTSA http://www.cs.utsa.edu/~dzhu

  2. Ideal World: I, Robot Do the Work • Need Rules and regulations to control the activities of robots!!!

  3. Three Laws for Robots, by Isaac Asimov • Law #1: A robot may not harm a human being • 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 or Second Law • Additional law: A robot must know it is a robot (should robots have feeling?!)

  4. Real Robot Examples • Vacuum Cleaning robots • Automatic assembly line • Research robots • Unknown space exploration • Unreachable • Rescue robots • Dangerous • Toys (expensive)

  5. The Current Technology • Humanoid Robots: Honda and Sony

  6. Definition for Robots from Wikipedia • A robot is a mechanical or virtual, artificialagent. It is usually an electromechanicalsystem, which, by its appearance or movements, conveys a sense that it has intent or agency of its own. • A certain level/degree of intelligence • Where does the intelligence come from?

  7. Brain of Robots: Computer Science • Hardware: Architecture and Organization • Processors/micro-controllers • Memory • Input/output interfaces • Software: Programming, Algorithms, OS • Resource management: OS • Behavior control: Algorithm • Planning: AI

  8. LEGO Robots: Education Platforms • LEGO Mindstorms Robots • Programming bricks (RCX) • Electric motors • Sensors • LEGO Technic pieces (gears, axles, beams etc) • Advanced controller: MIT Handy Board • Motorola 6811 • Digital and analog I/Os • Motor driver outputs

  9. How Do We Program Robots? Host computer for development Handy Board Target machine USB cable Phone cable Interface/charger Interface/charger

  10. Can ‘You’ Find the Water? • Water on Mars • Water in the middle • Regions • Obstacles • LEGO robots • Handy Board • LEGO sets • Motors • Sensors: light, touch, sonic http://www.cs.utsa.edu/~dzhu/cs4953
