● 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
