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

Ice Breaker•Draw a blueprint of a robot that performs
a task you would prefer not to do.
Structure Function
Determines
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
Bot or Not?

Bot or Not?
The NXT Brick is the brain of the robot
Output Ports (A, B, C)These ports send information out of the NXT
Motors are plugged into the Output PortsUSB Port –Connects to
the computer
INPUTS (1, 2, 3, 4) These ports send information into the NXT
Sensors are plugged into the Input Ports
Touch Ultrasonic
SoundLight
The NXT Navigation Map allows you to view the console menu options.
NXT BUTTON CONTROLSEnter/Select Button
Scroll controls allows navigation thru the menu
NXT BUTTON CONTROLS
You are able to scroll left to right thru all menu options.
NXT BUTTON CONTROLS
The back button allows you to return to the previous menu.
You are able to scroll backwards thru all menu options.

Gear Belts Angled Beams
Sensors Pulley Wheels Motor
Bushings Technic Beams
Axle Plates
Wheels Bricks
Pegs Studded Beams
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)
Now it’s time to build your bot!
If your wheel makes one rotation, how far will it travel?
Distance Traveled = Circumference * Rotations
Circle Math for Movement1. 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.The distance, through a circle’s center, from one edge to another.
Circumference = diameter * π
r
d
Π or Pi = 3.14
Measure to the nearest tenth of a centimeter
Measure to the nearest tenth of a centimeter
Circle Math In ActionIf your wheel completes 2 rotations, what distance will it travel?

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?

Circle Math In Action
Welcome to the programming environment. NXT G is a icon based user friendly drag and drop program.
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.
Math Applications•Metric conversions•Setting up equations•Perimeter•Circumference•Collecting and representing data•Estimation•Problem Solving: making predictions &
experimenting
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
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
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
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
First Lego League Core Values:• We are a team.

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
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.
