● Begins January 6th – Kickoff event
● 6 weeks
● Design,prototype, build, program a robot
● Most fun 6 weeks of the year
● Most challenging 6 weeks of the year
● This year’s challenge:
Build Season
4
● Official start of Build season
● Meet as a team to watch the
game release and brainstorm
(2 day event)
● Everyone should pre-download
the game manual(rulebook)
which can be decrypted with a
code after broadcast
Kickoff
5
● We start with brainstorming
● 2 days at the start of build season
● This is the most important part of our
entire season
● The decisions that we make early
have the greatest impact on the rest
of our season
Brainstorming
6
● Any idea from brainstorming needs
to be thoroughly prototyped and
tested
● We use Solidworks and 3d printing
to design and fabricate prototypes
● Keep prototypes simple!
● Important: Make sure proper
constraints are incorporated into
prototypes
Design and Prototyping
7
● Facilities creates field elements from
the game based on a manual FIRST
releases
● Expect updates as the season
progresses
● These elements must be as similar
in function as possible to the actual
game pieces.
Design and Prototyping
8
● We use Versa Frame, special 2’’x1’’ .1’’ thick tube. Has
holes spaced ½”
● Enables easy use of gussets
Frame Construction
9
● We use a variety of gussets and fasteners
● Gussets are flat plates used to attach two pieces
together
● Fasteners hold two or more things together
