Agenda
Review our Mission Forming your team Equipping your team Use EV3 Robots from last week to program more with the Mindstorms EV3 Software Managing your team Judging at the tournament Resources: firstlegoleague.org
Coaches Handbook 5
Our Mission We’re asking you to help us!
Program not just about building robots and competing in tournaments Teach skills Specific technical skills General life skills Show that technical problem solving can be fun The youngsters do the work – FLL Core Values and Coaches’ Promise Open up the possibility of technical careers One secret opportunity 6
Forming Your Team
7
Where Teams Come From
School Based In class: Perhaps 45 minutes a day After school: Perhaps 1.5 hours; 2 to 4 times a week Special block: Several hours once a week Club Based Probably after school or evening Independent team After school, evenings, or weekends We encourage you to find and include youngsters that normally would not have this exposure 8
Not a Drop-In Program
This is a project oriented program Parents and team members need to understand the commitment required Team members need to be available on a consistent basis to move their parts of the project forward from the first meetings through the season-end tournaments 9
Where to Meet
Large enough space to handle the number of youngsters on the team Space for challenge field setup – 4’x8’ Access to a computer Storage space between meetings Challenge table Partially built robot LEGO parts 10
Team size
High initial interest may fade Sub-teams of 2-3 can work in parallel Experiment with prototypes Learn programming techniques Work on the project Maximum team size allowed is 10 5 to 7 team members is probably ideal 11
You Need Adults, Too!
Coach – The person in charge Organizes the team Does not need to be a techie Mentor – The technical guru Provides technical advice Provides the technical basics One person can play both roles But, don’t go it alone Recruit other adults to supervise sub-teams 12
Coach – The Person in Charge
Single point of contact for team Understands the FLL and ORTOP programs Management expertise more important than technical expertise Point of contact for FIRST ® and ORTOP info Recruits the team Registers the team Arranges for equipment Schedules meetings Sets the philosophy and instills team spirit Is a good role model 13
Coach – Need to know
Responsible for ensuring the Team knows the rules and requirements for the current year’s Challenge Details on FIRST ® website: http://firstlegoleague.org/challenge/thechallenge Be sure you access the following key elements: “Robot Game” Includes Field Setup, Missions, and Rules “Robot Game Updates” Provides detailed interpretations and rule changes for missions and game rules. Updated frequently throughout the season, until Friday of Tournament weekend.
Project Generate and share an innovative solution to the Challenge theme Core Values Judging rubrics 14
Coach: Set Team Goals
Scale to experience level of team Samples Learn to program (...learn to use subroutines) Learn about (topic of year) Participate in tournament Complete at least 1 mission (more for experienced teams) Everyone participates HAVE FUN!
15
Mentor – The Technical Advisor
Technical Advisor to assist the coach Facilitates both robot design and programming skill sets Helps set achievable goals Encourages structured problem solving Follow typical engineering project models Experiment with one variable at a time Graduates of FLL can work as mentors 16
General Advice to All Adults
This is the kids’ project, not yours Be a good role model Keep a positive attitude Encourage teamwork and insist on mutual respect Don’t over emphasize “winning” – demonstrating a solution at a tournament is success Have fun 17
FLL 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 Coopertition™ in everything we do.
We have fun. 18

Team Uniforms??
Many teams do something for the tournaments Team shirts, hats, etc Theme clothing Team sponsor advertising on a T-shirt, etc. is OK Helps adults keep track of team 28
Let’s Take a Break As your first hands-on exercise for this workshop, your instructor will explain the Can-Do challenge
CanDo Challenge Discussion
Simple project, but good learning tool Unexpected things happen – cans get caught under the wheel, it goes the “wrong” direction Take it in smaller steps – “Let’s see what happens before it hits a can” Mechanical problems may do you in Clarify the “rules” – know the requirements Experiment – “Just go try it. We can rework it.” Keep it simple 30
Managing Your Team
31
Meeting Organization
How often and how long to meet Most teams meet 1-3 times per week After school, evenings, weekends as team desires Some add extras as get closer to end > 1 hr (set up and take down) < 3 hrs (attention span) At least 2 adults present during meetings – can use parents who take turns Set ground rules -- E.g. don’t turn kids loose to walk home by themselves after dark Refreshments / snacks ??
32
Team Kick-off Meeting
Welcome parents/guardians Set expectations with kids and adults Send kids off to build with LEGO Get assistant to help parts Use NXT or EV3 assembly booklet to build something Something they can all do at once Explain the real situation to the parents 33
Parent Involvement
Explain program/FLL philosophy Success = Participation Explain team rules (attendance, respect, ...) Discuss participation commitment for kids Review costs and funding sources Communicate about tournaments Solicit help 34
You Have A Team, Now What?
(Time Management) Divide the season Build A Foundation Address the Challenge Get It Done Practice like the Tournament Participate in Tournament (Judging and Field Challenge) 35
(Approx) Field Challenge Timeline
Assume 12 week season (24 meetings) 4 weeks: Build Foundation 6 weeks: Complete Challenge 2 weeks: Practice / Minor changes You may need to adjust these suggestions based on the time you have available to meet with your team 36
(Approx) Research Project Timeline
1 wk: Basic Research 2 wks: Narrow and Select Project Topic 1 wk: Focused Research 6 wks: Conduct Project / Prepare Presentation 2 wks: Practice and Present to Others These tasks run concurrently with the Field Challenge Timeline on the previous slide 37
Build a Foundation
Introduce techniques and concepts Build or bring demos Discuss advantages and disadvantages Let kids figure out how to apply concept to Challenge One approach: use 5-10 minutes at start of each meeting to introduce concepts Pick 1-2 subjects per session Can be more for first meetings / new teams May stop about ½ way thru season – A bit late to incorporate new concepts unless they are stuck 38
Foundation: Sample Concepts
Pick one or two new subjects per session Structural strength: bracing vs. snapped pieces Gear ratios: torque vs. speed Traction: tracks vs. wheels Friction: tires vs. skids Programming techniques: linear vs. loops vs. subroutines 39
Foundation: Mechanics
Robot basics: have team build 2-3 different robots with instructions e.g. one per meeting Discuss “+”, “-” of designs Team decides/combines for challenge robot Gives team general robot building and design tradeoff experience Build Field Kit Dedicate 1 meeting, divide up elements Ad hoc extra meeting for leftovers 40
Foundation: Divide and conquer
Three basic robot functions: Locomotion: how the robot moves Concepts: motors, gears/pulleys, wheels/tracks, friction, steering Navigation: how it knows where to go Concepts: time, sensors (rotation, touch, light, ultrasonic) Robotic Action: function it performs Concepts: pushing, grabbing, lifting , dumping 41
Foundation: Programming
Introduce basic programming Can use Workshop handouts Introduce sensors If meetings start before Challenge is announced, can use mini-challenges to introduce concepts Use Catlin NXT/EV3 tutorials www.stemcentric.com
42
Foundation: Structured Problem Solving
Teach them elements of structured approach to solving large problems Defining problem Brainstorming Evaluating alternatives Choosing alternative Implementing Evaluating & testing 43
Address the Challenge
Pick up all information about the challenge from FIRST ® website when details announced on August 26 th Missions Rules Field setup Game Updates (grows during the season) Project – details on research project Core Values 44
Address the Challenge
Team must learn mission and rules: Send home copy and learn missions and rules Discuss and test understanding at later team meetings Can overlap with ‘build foundation’ meetings You might want to find a “rules expert” among your team members 45
Address the Challenge
Have team group missions Members brainstorm/generate prioritized list: Can prioritize group by ease, location, or points Can group by program or trips out of base Individuals present and team selects which to start with Refer to team goals for how many to try Can add more if finish 1 st set and still have time 46
Address the Challenge
Team decides how to divide responsibilities A) Builders / Programmers B) Mission based (build/program by mission) C) ??
Need duplicate coverage for illness/absences Probably want area specialists (build, program, research, etc.) BUT Recommended ground rule: Everyone contributes to all aspects of team’s work 47
Get It Done
Considerations: Introduce “design rule” concept Shared, agreed upon design constants e.g. Motors B/C drive and motor C is on right Which end is ‘forward’ Light sensor is always in port ‘3’ Programs need to share inputs/outputs Attachments need to go together Base robot with quickly interchangeable attachments, or Attachments can’t interfere with those for other missions Target being done early (time for debug/rebuild) 48
Practice Like the Tournament
Field Competition Runs (tournament rules) Start with individual missions/groups, then all together 2 ½ min, 2 members at the table at once Practice working under time pressure Switching between missions, programs Try to limit big last minute changes to missions/robot 49
Practice Like the Tournament
Judging Panels (Robot Design, Project, Core Values) Use Coach Handbook rubrics Parents as judges Work on smooth, clear delivery Ask a variety of questions Practice teamwork exercises 50
Final Advice: Budgeting Resources
Physical resource effectiveness limits: No more than 2 (3 max) at one keyboard No more than 2-3 building one item Can’t research presentation and program robot on same computer at same time Consider time sharing 2 computers, one robot kit; divide team 1/3 building, 1/3 programming, 1/3 researching Rotate during meeting 51
Final Advice:
Set Expectations For a Positive Tone Encourage risk taking It’s OK to fail – they are learning opportunities Key is to manage the risk Encourage experimentation Expect failure – focus on what is learned as a result Problem solving takes time – Edison’s experience with light bulb filament 52
Final Advice
Keep Meetings Fun Usually means hands on LEGO building every meeting Be flexible Help keep them on task, but ultimately it is their project The journey is as important as the result Watch for teaching moments Engineers need ‘hard skills’ Mechanical Design, Programming, Analysis, Problem Solving, Experimentation, and Documentation AND ‘soft skills’ Timeliness, Teamwork, Tact and Compromise, Confidence, Courtesy, Perseverance, and Planning 53
With All the Focus on the Robot and the Challenge…
Don’t Forget the Judging
Robot Design Judging
Panel of “experts” interviews teams Robot design: Creativity and robustness Programming: Creativity and robustness Prepare the team to: Give a 1 minute overview of their robot design noting “sources of inspiration” Answer questions about the design of the robot and its program Demonstrate at least one mission on the challenge field Bring a printout of the program 55
Project Judging
Another good learning opportunity Research skills and presentation skills (remember the marketing kid? ) Good engineering requires research and communication Must be a live presentation Format – includes setup time 5 minute presentation, 5 minute interview Posterboards, skits, models, Powerpoint (not the best format, can waste time with setup), . . . 56
Core Values Judging
A separate 10 minute judging session Teams will do a surprise teamwork activity At Championship tournament the teams bring a Core Values “tri-fold” or poster with them and give a short, less than 2 minutes, presentation on the contents Judges interact with teams to evaluate how the teams meet the FLL Core Values 57
FLL Core Values Team Observations
Tournament officials observe teams during tournaments at all activities Looking for exceptional positive or negative demonstrations of FLL Core Values throughout the day Observations can impact a team’s score either positively or negatively Hand out FLL Core Values Team Observation sheets 58
FLL Core Values Best Practices
Youngsters design, build, and program their robots Youngsters are responsible for project work ORTOP rule: During tournament, no adult may touch the computer keyboard, mouse, robot, robot attachments, or project materials.
ORTOP rule: No adult may give specific verbal directives on programming and building or during table competition at a tournament.
Tournament guidelines should be in effect at team meetings. 59
What if …?
Teams may use software or mechanical designs that they find on the Internet Good engineers build on the design work of others and don’t reinvent the wheel We encourage the use of our building instructions to get your team started with its first robot But, there are responsibilities that go with this!!
Use of Third Party Materials
Team decides what to use and why they want to use it They must be able to explain how the software or mechanical design works and why they included it They must give credit to any such third party material that they use (Bring your “sources of inspiration” list to the Robot Design judging)
