  1. Robotics: Making Computer Science and Engineering Come Alive!ISTE 2010: TP426L Lego Education www.legoeducation.us Booth #632 Christopher Michaud Paulding County Public Schools Dallas, Georgia nebomusic@gmail.com www.nebomusic.net

  2. Overview • Build • Program • Experiment • Apply

  3. Objectives • Build Basic Vehicle Robot from directions • Using NXT-G software • Distance, Direction, Duration • Sensors • Missions • Application to Math and Science Standards

  4. Why Programming and Robotics? • Programming allows students to encode and reflect on sequential and logical thought in a dynamic system. • Real applications of math concepts • Distance, Direction, Duration • Boolean Concepts • Develops Technological Fluency

  5. What is a Robot? A Robot is a machine that can be programmed to do a task without being directly controlled by a human being.   There are two parts to a robotic system. • Hardware: This is the mechanical robot. The motors, gears, wheels, parts, computers that make up the machine.  This is the part you build. • Software:  This is the instructions for the tasks and actions the robot will do.  This is the part you write.MINDSTORMS NXT is used to create the software that controls the actions of the robot hardware.  NXT MINDSTORMS software is a visual/icon system of assembling instructions.  The flow of direction usually moves from left to right.  This software is an example of a compiled program.  Programs you write in NXT must be compiled and downloaded to the NXT Brick before the Robot will perform the program.  (Scratch and Python are "Interpreted Languages.")

  6. Why Robotics? • Humans are creators and builders • We like to “Give Life” to objects • Robotics embody logical thought in action through time in the real world • “See” our thoughts in action and reaction • Robotics will continue to play bigger roles in human society • They are cool!

  7. Hierarchy of Technology Skills 1. Passive Reception: From creator to receiver with no action on receiver to alter flow of content. (watching a video) 2. Active Research: From creator to receiver with receiver selecting path and specific points of content. (Surfing the web) 3. Interactive 1 way: From creator to receiver through game model.  Receiver must master a skill to progress through activity. (Skill and Drill) 4. Communication / Expression: User creates content and art with technology.    Verbal / Text    Images    Plot    Web 5. Interactive 2 way: creator and users interact. (Email, Blogs, Multi-User Virtual Environments) 6. Data manipulation and Analysis: User uses computer to interact and manipulate the content and data. 7. Software creation / programming: Users encodes logical thought and algorithms into computer. User tells computer what to do. Provides platforms and engines for above skill sets. 8. Hardware creation: User designs and assembles hardware to run, input, display software.

  8. “The Big Trends” • Transportation • Sailing Ships, Railroads, Automobiles, Airplanes • Encoding and Moving Human Thought • Written Language, Printing Press, Internet, Web Browser • Web 2.0, Small Handheld Computing- Automation of Moving Human Thought • Next Innovation - Automation of Transportation - Robotics

  9. Robot Base • Easy to Build • Stable, Symmetrical, and Strong • Flexible for different projects

  10. Sources for Robot Plans • http://www.domabotics.com • http://nxtprograms.com/ • http://mindstorms.lego.com/en-us/history/default.aspx • http://mindstorms.lego.com/en-us/community/NXTLog/default.aspx • www.nebomusic.net

  11. NXT-G Programming Tutorials • http://www.ortop.org/NXT_Tutorial/

  12. Input (Sensors) Touch Sound Light Ultrasonic Many others Output Motors Lights Sound Screen NXT-G Programming • Processing • Logic • Math • Conditionals

  13. Basic NXT-G ProgrammingMovement/Motor Blocks (Output) Movement Blocks direct motors A, B, or C to rotate clockwise or counterclockwise.  The motors have sensors inside them that can measure how much they rotate.  Motors C and B usually are used for the drive wheels on a vehicle Robot.   You may change the following variables on a motor on the details window.

  14. Programming Challenges! • Drive a Rectangle Activity: • http://www.nebomusic.net/NXT-G-DriveARectangle.html • Maze #2 • Distance and Turns Worksheets • Maze #1 • Basic Line Following • http://www.nebomusic.net/NXT-G-BasicLineFollow.html • “Cap the Well” Activity

  15. Touch Light Ultrasonic NXT-G ProgrammingSensors (Input) Many Others: Sound Color IR Magnetic Gyroscope

  16. Wait Block NXT-G Programming3 Types of Conditionals (Logic)

  17. Switch Block NXT-G Programming3 Types of Conditionals (Logic)

  18. Loop Block NXT-G Programming3 Types of Conditionals (Logic)

  19. Basic Line Following

  20. Intermediate Line Following

  21. Missions • Basic Types: • Follow a Course • Go and Get • Go and Do • Go and Put • Go and Stay • Try to Relate Missions to real world problems. (Example: First Lego League themes like transportation, energy, biology)
