  1. For today, you will need: NXT Video Trainer installed NXT-G installed Robot built Firmware downloaded NXT-GOnline Professional DevelopmentClasses will begin at 1:00pm EDT

  2. Welcome • Last week: GoToWebinar, Forums, FLL Coaching • Technical issues/questions? • This week: Moving Around

  3. NVT Moving Straight • First NXT Video Trainer (NVT) lesson • Demo: How to get around in the NVT • Lab: NVT Moving Straight 1-9 • Answer the questions at the end of each step to yourself • Check your answers so you know whether you got it or not • If you finish early, answer the following question: • What is the relationship between Rotations and Degrees in the Duration configuration panel? • How does Seconds fit in with Rotations and Degrees? • Still done early? Continue on with the steps… • Report in the poll at right when you are done

  4. NVT and You • Everyone learns different things at different paces • Everyone MUST move at a different pace • Going too fast results in failure and frustration • Going too slow results in loss of attention (i.e. future failure) • The NVT software is a teaching aid • FLL is about student growth through experience • You can’t micromanage every single student’s experience • The NVT can help your student programmers just as it will help you in this course • Plus you’ll know what to expect!

  5. Adjusting Distance • Lab: NVT Moving Forward 10-11 • Do the Step 10 and 11 Challenges at the end of the videos • If you finish early, create the following: • A digital document (Word, PPT, Wiki, anything…) with step-by-step instructions answering each of the questions below • Adjusting Distance • How do you make the robot go farther? • How do you make the robot go less far? • How do you make the robot go a specific distance?

  6. Close Shave Challenge • Challenges and Projects • Complete the Close Shave Challenge • NVT Moving Straight 14 • If you finish early 1: 2.5 Tiles • If you finish 1, 2, and 3 tiles, also prepare for 2.5 tiles • If you finish early 2: Present your solution • Prepare a 1-2 minute presentation (visuals OK via screen sharing) describing your method for finding the correct Durations

  7. Many Different Tools “Waiter, there’s a math problem in my robot class!” Why, so there is! “Well, what’s he doing there?!” Cross-multiplication, sir.

  8. Many Different Tools • How did you solve the math problem? • Some common methods: • Scale Factor (“Scaling” multiples of a known quantity) • Rate: Unit Ratio (# of X in a single Y, times the number of Y’s) • “Rate” relationship • Find #degrees/1cm, then multiply that rate by the total • What about #degrees per floor-line? • Rate: Raw Ratio (# of X per # of Y, times the number of Y’s) • Find 360degrees/20.4cm, then multiply that rate by the total • Direct Proportion (Traditional “ratio” equation) • 20.4 cm = 50 cm360 deg X deg • Solved mechanically using cross-multiplication • Solved algebraically as a Linear Equation of One Variable

  9. Answer Problem Many Different Tools • Did you all solve the same problem? • Did you all get the same answer? • Did you all use the same method? • Did it matter?

  10. To measure distance, we have many tools…

  11. Many Different Tools • Why should robotics be any different? • Give students more tools and more experience in choosing and using them! • When Math is the correct tool… • Make the math explicit; don’t waste the opportunity! • Embrace multiple methods of solving the same problem

  12. For Next Class… • Complete NVT Turning • NXT Video Trainer > Behaviors > Turning • Build the Labyrinth with removable tape on a floor • Complete the Labyrinth! • Errata: U-Turn • Build Touch+Light and Raised Ultrasonic Attachments • Found in the NXT Video Trainer > Basics section

  13. Closing Thoughts • Class activity: Moving Straight Lab • Coaching concept: Using the NVT with Students • Class activity: Proportional Movement • Mentor concept: Tools Including Math
