2 Who are we? Anne Shade 17 th year in FIRST FIRST Regional Director, Maryland Former 2377 General Manager and Coach ( ) Steve Shade 16 th year in FIRST Lead Team Development Subcommittee Chesapeake Regional Chesapeake Regional Head Referee Former 2377 Lead Engineer and Coach ( ) Senior Engineer Modeling and Simulation, Rolls-Royce Marine North America 2

3 Overview Decision Making Understand the decision matrix tool Game Analysis Understand how to play the game Determine how many points is needed to win matches Construct a game strategy to meet the point goal Robot Requirements Translate team strategy into robot requirements Describe resources for the build 3

4 Ground Rules No right way to build competitive robots Our system has worked for many teams Our system is adapted for each team and game, but basic tools still apply 4

5 Common Themes Write it down Post it up Questions What do you want to accomplish? Who is responsible? How are you going to accomplish it? Repeat 5

6 Decision Making Process Process normally included as part of the Team Handbook Consensus Approach Decision Matrix Tool is a favorite Quality Functional Deployment / House of Quality (QFD/HOQ) is more thorough but complicated Affinity techniques Limit the use of voting Too easy to go with the cool option, even if it doesn t fit with the team strategy At some point there needs to be 1 person empowered to make a decision for the good of the team Must be willing to make the call even when unpopular for the majority 6

7 Decision Matrix Establish decision criteria Establish criteria weights Complete matrix without weights shown Apply weights Evaluate results 7

8 Decision Criteria What are the most important criteria to your game strategy? Need about 5 to 10 criterion. Examples Scorability Complexity Reliability Penalty Risk 8

9 Decision Criteria Rate the importance of each of your decision criteria. Each criteria needs a rating between 1 (little importance) to 5 (high importance) Don t multiply out the matrix until all raw scores are filled in. 9

10 Decision Matrix - Filled In > 3 better than reference < 3 worse than reference = 3 same as reference Criteria Weight Concept 1 4WD Toughbox 2 Motors Raw Score Weight ed Score Concept 2 6WD Toughbox 4 Motors Raw Score Weight ed Score Concept 3 6WD SuperShifter 4 Motors Raw Score Weight ed Score Concept 4 Holonomic 4 Motors Raw Score Weight ed Score Weight Power Traction Maneuverability Complexity Maintainability Reliability Durability Speed Cost Concept 5 Mecanum 4 Motors Raw Score Weight ed Score Weighted Total 10

12 Big Picture Robot Building Process Robot Requirements Robot Testing Team Strategy Robot Design Robot Construction 12

13 Game Analysis Goals Understand how to play the game Score points Major fouls Start defining each team s strategy WHAT your robot is going to do Next Step - Define HOW your robot will accomplish the strategy Develop robot requirements NO PARTS OF THIS DISCUSSION INCLUDES TALKING ABOUT HOW TO BUILD THE ROBOT!!! 13

14 Game Analysis Process Evaluate the Game Arena Scoring Opportunities Fouls Ranking Process Match Scores Alliance Team Qualifying Eliminations Develop Strategies Brainstorm methods to achieve the target match score Design Robot Goal - Achieve Strategy Robot Requirements act as design guide Develop Robot Requirements Demands Wishes Select a Strategy Decision Matrix to select a strategy 14

15 Example 2014 Aerial Assist Tele-Op Ball 10 Truss 10 Catch 10 Assist 0, 10, 30 Cycle Total 60 Autonomous Mobility Ball Hot Bonus 5 per robot 15 per ball 5 per ball Auto Total 75 15

16 How do we play the game? What is each object / robot worth when scored? Are there bonus points (e.g. winning autonomous, minibot race)? Limited number of objects (e.g 2011) or do objects cycle (e.g. 2010)? Is there a maximum match score? How are teams ranked? 16

17 The Big Questions How many points does an alliance need to score to win a match? 17

18 Example Aerial Assist (continued) Effects of Autonomous Maximum Effects of Cycles Auto/Truss/ Catch Mobility Ball Total Tele-Op Ball Truss Catch Cycle Total Cycles Total Total Match

19 The Big Questions How many points does our team need to score to win a match? 19

20 Example Aerial Assist (continued) Autonomous Option 1 Option 2 Option 3 Option 4 Option 5 Mobility Ball Total Tele-Op Ball Truss Catch Cycle Total Cycles Total Total Match

21 Game Strategy Your team does not have to score all of the alliance points, just assist in doing so. Best to drive and do one thing really well, than to do many things OK or worse. Not interested in what needs to be built in order to make the strategy a reality. 21

22 Strategy Development As a team, brainstorm strategy concepts that would help your alliance reach the point goal for each match. Examples (2011) (55-60 pts/match/team goal) 1 Ubertube top row and 2 top row Logos + 4 th place minibot (58 points) 1 Ubertube top row and 1 top row Logo + 1 st or 2 nd place minibot (60 points) 1 Ubertube middle row and 2 middle row Logos + 1 st place minibot (58 points) 22

23 Strategy Selection Develop a set of strategies that will realistically meet your points goal Select 3-6 possible strategies to evaluate Use a decision matrix to select a strategy concept that will be the team s focus for the next six weeks 23

24 Percent Occurrence How close were we at kickoff? Qualifying 2014 Elimination 82.5% of Qualifying and 75% of Elimination matches scored 157 or less Data from The Blue Alliance Alliance Scores 24

25 Robot Requirements Now that we know WHAT we want to do, we need to figure out HOW we are going to accomplish the task. Establish Robot Requirements Demands Weight Size Kick Ball across field (e.g. 2010) Wishes Kick 10 Balls per Match (e.g. 2010) Hang in 5 seconds or less (e.g. 2010) 25

26 Defining Specifications Specification Sheet Example D=demand W=wish D/W Specification Requirements Responsibility Source D Weight - Under 120 lbs (excl. Battery + Bumpers) Team FIRST W Drive Train - Under 40 lbs Drive Team W Manipulator - Under 50 lbs Manipulator Team W Electrical - Under 20 lbs Controls Team W Spare Weight - 10 lbs Team Team Drive Train - W Speed 8 ft/s Drive Team D 6 Wheel Drive Team Manipulator - D Pick up tetras Manipulator Team W Pick up 3 tetras at a time Manipulator Manipulator Maintenance - D Be able to change out gearbox in 10 minutes Drive Team Cost - D Under $2000 Team FIRST Schedule - D Be finished in 6 weeks Team FIRST W Have Drive train complete by Week 3 Drive Team 26

27 Determine Robot Requirements As a team, start putting together your team s specification sheet. Start to include engineering requirements (with units) such as robot speed, number of objects to handle, speed to perform a task, etc. Include breakdowns (like weight or size) when known, estimates are OK for now. 27

28 Designing Robot Systems Find examples Robot in 3 Days 5 separate designs in 2014!!!!! Team 45 s Ball grabber in 98 & 04 45, 121, 1902, 2377 robots from 2008 Design Philosophies Detailed Paper or CAD design then construction Prototype concepts from the start until proof of concept is achieved, then complete design and build No matter what, need to track weight! 28

29 Host Your Own Kickoff Teams are encouraged to host own kickoff events Space limitations at Capitol Technical University to view kickoff Contact Anne Shade if willing to share kickoff space 29

30 Resources ChiefDelphi Discussion Forums Team Updates FIRST Q&A MD FIRST Team Support including Anne and Steve Robot in 3 Days Ri3D (Ri3D, AndyMark, Boom! Done) Vex Pro (Team Copioli, Team JVN) FIRST Technical Resources l-resources 30

31 Once Built Re-evaluate Strategy How close are you to your initial goals? Be Realistic with what you can do Know the machine limits Watch how game is played at other events Game play evolves, very different each week Keep Improving Design Apply good ideas from what you watched Expand Horizons Style of play is different in other parts of country 31
