Collaborative Collaborative Problem SolvingProblem Solving
Bill Hommes
What am I going to tell you about?
Creative Process we have used for the past
6 years to develop the concept for our robot Final concept is selected in 3 days Full participation by Students in Concept development
and selection – everyone has equal input Have always stuck with concept selected with full
team support – no second guessing
“To Thrive in the Age of Instability Requires a Distinctive Corporate Culture….
…a culture that breeds an endless search for ideas that stand or fall on their merits, rather than the rank of their originator, a culture that brings everymind into the game.”
(Jack Welch)

Key Factors in Consensus Decision Making
What’s your Team’s Common Goal?
• Functional Robot• Competitive Regionally• Regional Champion• Competitive nationally• National Champion
Day 1 Goal - Develop Understanding of Game
Common Understanding of game
Potential Robot Capabilities Game Strategies
Day 1 – Common Understanding
• Watch Kick-off event• Goal is to insure everyone has understanding
of the game– Game description– Field Layout – Scoring
• Chart key points • Make Sketch of field layout
Day 1 – Potential Robot Capabilities
1 hold multiple tetras
2 long reach placement of tetras
3 see vision tetras
4 place a skewed tetra to prevent others from scoring
5 cap with more than one tetras at a time
6 push other robots
7 get tetra off loading station
8 cap high goal even with number of tetras already stacked
29 block other robots from capping
30Precision navigation to allow tetra placement
• • •
• Brainstorm WHAT functional capabilities you might want your robot to have
• Goal is to continue to improve understanding of game and implications on robot• List all suggestions but do NOT discuss HOW to do these things!!!!
Day 1 – Potential Strategies
• Brainstorm what strategies are possible
Block others from capping Maximize Tetras – score as many tetra’s as possible Maximize rows - focus on completing rows rather than #’s– Maximize value of autonomous Add tetras to game– Prevent opponents from getting tetras
• Select up to four strategies to develop further – CONCEPT STRENGTHENING
Goal of Concept Strengthening• Develop and strengthen the strategies by identifying
and overcoming key limitations• Avoid the common idea-slaughtering that occurs
when groups confront novel or unusual options
1. Break into 4 groups – one for each strategy2. Select leader for group (1 student/1 mentor)3. Spend 20 minutes working on your strategy4. Rotate to next group
• Leaders stay behind to explain to new group• Spend 10 minutes improving• Rotate to next group
Involve Everyone !!!
Concept Strengthening
• Advantages – List the top 2-3 advantages of strategy
• Limitations – why might this strategy not work, where might it fall short
• Unique Qualities – what are the unique elements we need to preserve
What does this strategy have that few or none of the others haveWhy is this strategy different
• Develop detailed game strategies to overcome key limitations – describe 2 minute matches
2 min.
2 min.
3 min.
13 min.
20 minutes
Day 1 - Wrap-up
• Each group reports back
– Do they recommend continuing to pursue strategy
– If yes, what is best means of implementing. Described a a 2 minute match
• Homework - Think of how you would build a robot to implement whatyou think is the best strategy

In what ways might we build a robot to
play triple play?
Problem Statement
The best way to get a good idea is to get lots of ideas.

Guidelines for Creativity Session
• Record Idea on Concept
Sheet
• One idea per Sheet
Sequentially number concepts as presented

Agenda for Day 2 – Idea Generation
Forced Relationships:
Randomly grab a concept from a neighbor and combine it with the last concept you created and come up with at least one new idea that combines the two.
Forced Visual RelationshipsForced Visual Relationships

UNLOCK YOUR THINKING
Now,Let’s try to make it work…
Categories
• After sharing we will need to group ideas by category• Goal is about 5-10 ideas per category• Look over your ideas and think of some categories • What categories did you identify – need 20
# Categories1 tetra catch or gripper2 drive train3 arm mechanism4 tetra storing on robot5 stablizers6 sensors7 blocking mechanisms8 cappers9 general robot principles

Day 3 – Concept SelectionDay 3 – Concept SelectionCriteria
ConvergentThinking
Divergent Thinking
ProblemStatement Robot Concept
• Ability to play game– # of Points– flexibility in strategy
• Feasibility– Can we finish in 6 weeks– Robot Robustness
Selection Criteria
• Identify the top 4 ideas – keep criteria in mind
• Review Ideas and make note of best ideas
• Trust your first impressions - decide quickly
• Once everyone has decided we will poll the group
Preliminary Preliminary SelectionSelection
Preliminary Selection
• Place dot on selected conceptsOr if available Wireless Polling technology
• Everyone decides before they vote – Avoids “Herd Mentality”
Preliminary Selection - total votes by concept #
All Concepts Receiving Votes Grouped into Clusters:
Cluster 1 – Helper Bot – feed tetras to partnerCluster 2 – Load Station/GoalPlacementCluster 3 – Telescoping/Rotating ArmCluster 4 – Fork lift Cluster 5 - Articulating ArmCluster 6 – Gripper conceptsCluster 7 – Defensive Bot – block other robots
Cluster Ideas Remaining after Preliminary Selection
Final Ranking of Clusters
Rank Clusters-Ability to play game-Feasibility of completing in six weeks
Everyone votes – (1-10)- Tally votes- Discuss & Select final Concept
