Mingo County Shewey Science Academy: NXT Training

1. Mingo County Shewey Science Academy: NXT Training

2. First Lego League • Highly differentiated • Hands-On • Student-led • Cross-curricular • Collaborative

3. First Lego League Core Values: • We are a team. • We do the work to find solutions with guidance from our coaches and mentors. • We know our coaches and mentors don't have all the answers; we learn together. • We honor the spirit of friendly competition. • What we discover is more important than what we win. • We share our experiences with others. • We display gracious professionalism and cooperation in everything we do. • We have FUN!

6. Ice Breaker • Draw a blueprint of a robot that performs a task you would prefer not to do.

7. Structure Function Determines

8. What is a Robot? • Sense–takes in information about its environment • Plan –uses that information to make a decision • Act –has moving parts to carry out commands

9. Bot or Not?

10. Bot or Not?

11. Bot or Not?

12. Bot or Not?

13. The NXT Brick is the brain of the robot

15. Output Ports (A, B, C)These ports send information out of the NXT

16. USB Port –Connects to the computer Motors are plugged into the Output Ports

17. INPUTS (1, 2, 3, 4) These ports send information into the NXT

18. Sensors are plugged into the Input Ports Touch Light Sound Ultrasonic

19. The NXT Navigation Map allows you to view the console menu options.

20. NXT BUTTON CONTROLS Enter/Select Button

21. NXT BUTTON CONTROLS Scroll controls allows navigation thru the menu

22. You are able to scroll left to right thru all menu options.

23. NXT BUTTON CONTROLS The back button allows you to return to the previous menu.

24. You are able to scroll backwards thru all menu options.

25. Name that Part! Word Bank: Gear Belts Angled Beams Sensors Pulley Wheels Motor Bushings Technic Beams Axle Plates Wheels Bricks Pegs Studded Beams

26. Functions Bricks, Beams, & Plates: Provide stability and support Gears, Belts, Axles, & Pulleys: Transmit mechanical energy Bushings: Hold structural parts in place; can also be used as part of a pulley system Pegs and Joints: Join structural parts together Sensors: Detect changes in the environment NXT (Brain): Contains the source of energy for the bot (batteries)

27. Now it’s time to build your bot!

28. If your wheel makes one rotation, how far will it travel? Distance Traveled = Circumference * Rotations

29. r d Circle Math for Movement • What is a radius of a circle? • 2. What is a diameter of a circle? • 3. What is the formula for the circumference of a circle? The distance from the center to the outside of a circle. Measure to the nearest tenth of a centimeter. Measure to the nearest tenth of a centimeter The distance, through a circle’s center, from one edge to another. Measure to the nearest tenth of a centimeter Circumference = diameter * π Π or Pi = 3.14

30. Circle Math In ActionIf your wheel completes 2 rotations, what distance will it travel? Round up 2.2 cm 3.14 6.908 6.91 Measurement of the rim Constant 13.82 cm 6.91 2 Resource: Robin Shoop, Carnegie Mellon University

31. Circle Math In Action If your wheel’s circumference is 6.91 and it completes 2 rotations, then it should travel 13.82 cm.Climbing the Learning LadderWhat are some variables which would prevent the Robot from traveling exactly 13.82 cm? Resource: Robin Shoop, Carnegie Mellon University

32. Welcome to the programming environment. NXT G is a icon based user friendly drag and drop program.

33. If you have multiple NXT robots in your classroom, a best practice is to have students personalize their robot by giving it a name that is saved in the robot’s brain.

34. Math Applications • Metric conversions • Setting up equations • Perimeter • Circumference • Collecting and representing data • Estimation • Problem Solving: making predictions & experimenting

35. 4/20/13 • Objectives- • Use the scientific process to solve the Green City Challenges. • Complete two green city challenges: • 1 that requires a “push” from the robot • 1 that requires your robot to “lift” something

36. Best Practices: • Assigning roles: i.e.- mechanical engineer, computer engineer, mathematician • Following the scientific process • Data Logging • Organization: Challenge kids to keep kits organized! • Lego League Core Values • Awards

37. Scientific Process: • Know the challenge • Predict what your robot will do to solve the challenge • Experiment • Evaluate results • Make changes due to inconsistencies in the prediction • Experiment • Repeat

38. Data Logging Example Challenge: Move in a square Behavior Programming Robot will move forward 8 in. Robot will execute a point turn by turning off left wheel and allowing the right wheel to move Robot will repeat steps above 3 more times. Forward move block, 2 rotations Forward move block with C motor turned off, 1 rotation Use Loop Function

39. First Lego League Core Values: • We are a team. • We do the work to find solutions with guidance from our coaches and mentors. • We know our coaches and mentors don't have all the answers; we learn together. • We honor the spirit of friendly competition. • What we discover is more important than what we win. • We share our experiences with others. • We display gracious professionalism and cooperation in everything we do. • We have FUN!

40. Green City Challenge Awards: • Best Design of Robot • Most Difficult Challenge • Fastest Mission Completion • Most Effective Mission (highest point value) • Most Creative • Most Gracious Professionals

41. Trouble Shooting • Emphasize that the robots must begin on the designated tire outlines • Charge robots each day after students leave • Programming Issues: • Ensure the arm or wheel is connected to the correct port • That the student is downloading the correct program • That all pieces of the robot fit tightly • That the battery life of the robot is fully charged or close to it.
