Gameplay

is
seperated

into three
different areas this year


1: The first area is called transistor fabrication.


This is the multicolored wooden dowels and the cups in
which they are to be placed


2: The second area is called IC (integrated circuit)
fabrication.


This is the rack of multicolored coat hangers and the
wooden posts with PVC pipes on which they are to be
hung


3: The third area is called the CPU (Central
Processing Unit) fabrication area.



This is the table in the middle of the playing field that
has slots for the foam pieces on the floor to be placed
in.

Objective



In short the objective for the game is to build the
best CPU (foam puzzle pieces in stage 3) possible.


In order to build the CPU

1.
G
ates (dowels from stage 1)must be built

2.
Integrated circuits (coat hangers from stage 2) must
be built

3.
IC’s (foam pieces) are used in stage 3 to make the
best CPU


The scoring software will keep track of how many
gates and IC’s and CPU’s have been made for
each team during the entire competition


No gates and no IC’s means no CPU

Stage 1

Gate Fabrication (Dowels)


This stage of the
competition requires
teams to take the
wooden dowels
(transistors) on the
bottom rack and place
them into the bins
above


Different bins account
for different points


Lower bins are worth half
the points upper bins are


W
hite ends out mean half
the points of red ends out


NAND bins (the ones facing
the other way are the same
as far as points and gates as
the upper bins

The purpose of creating transistors is to be able
to use them for gates in the second round


Below is a table of how many transistors are
required to create each type of gate that is
required in stage 2


For example: if a team scores a dowel with red
end out on the upper assembly line of the and
section then they score 96 AND transistors. This
translates into 4 AND gates (4 red hangers) that
can be used in stage 2


Stage 2

Integrated Circuit Fabrication
(Coat Hangers and posts)


This stage of the competition
requires teams to take gates
(coat hangers) and place them
on PVC pipes jutting from the
wooden posts


The purpose of this stage is to
build the
cpu

pieces or IC’s
(foam pieces) needed for stage
3


Teams are only able to use the
gates (dowels from stage 1)
that they have already
assembled (from previous or
current rounds)


Lower PVC pipes are half as
fast as upper ones



First tower is the MUX (Multiplexor)


Second is the Adder


Third is the Decoder


Last is the D
-
Latch (Data Latch)


Building Integrated Circuits


Gatekeeper:
Clothes
hangers

represent
gates. To build an
integrated circuit,
calculations must be
made to determine the
number and type of
gates needed to create
each
circuit.
Remember, inventory is
required from Stage 1:
Gate Fabrication Area.

1 Red hanger = 1 AND gate

1 White hanger = 1 OR gate

1 Blue hanger = 1 NOT gate

1 Black hanger = 1 NAND gate

IC Fabrication cont’d


Hangers can be suspended by the
PVC in any fashion as long as they
are not supported by the field


IC is only as efficient as lowest
hanger.


For example, if a team was building a
D
-
Latch (needing only two black
hangers) and had one black hanger
on the upper post and one on the
lower post then the team would only
receive one D
-
Latch gate.


If the team were to place both the
black hangers on the upper post then
they would receive two D
-
Latch gates
since the upper post is running at
double speed

Okay, this is a little confusing, no?


Here’s a little recap


Dowels in buckets = Transistors


Use table to know how many
gates are produced from
transistors


Gates (hangers) are used in
stage 2 to produce the foam
pieces needed in stage 3 for the
CPU and memory


MUX = Multiplexor (first tower)


Adder = (Second tower)


Decoder = Instruction/Address
Decoder (Third tower)

Latch = Register/Memory Unit

Stage 3

CPU Fabrication (Foam Puzzle
Pieces)


The purpose of this stage is to
take the foam pieces (CPU and
memory components) and place
them on the board to make the
best CPU and Memory possible


The foam pieces are
representations of the IC’s made
in stage 2 with the coat hangers
and posts


D

Latch = Register/Memory Unit


Decoder = Instruction
Decoder/Address Decoder


Adder + MUX = ALU


The BEST CPU Fabrication Area

The BEST
CPU

Fabrication Area consists of

two sub
-
areas:



Core Processor Area
(located on the left)



Memory Module Area
(located on the right)


Fabricating a Core Processor

(The square board on the left)

A
BEST Core Processor
requires:



(3) Registers
(made by placing
one D
-
Latch
into


each designated area)


(1) Instruction Decoder
(made by placing
one


Decoder

into the designated area)


(1) Arithmetic Logic Unit (ALU)
(made by placing


one MUX and one Adder

into the designated areas


Fabricating a Memory Module

(The rectangular board on the right)

A
BEST Memory Module
is capable of fabricating two

types of memory modules:


8
-
bit Memory Module
(made by placing
one D
-
Latch


into any one of the Memory Unit slots)


32
-
bit Memory Module
(made by placing
four


D
-
Latches and one Address Decoder

the Memory Unit and
Address Decoder slots)

Inventory System

Gatekeeper utilizes an inventory system that is independent
from scoring values:



Components fabricated in each stage are
placed in a
team’s
inventory


This

inventory is NOT represented physically
, but is instead
maintained by the
BEST Scoring Software


Hubs will provide a display for viewing team inventory, but it
is

HIGHLY RECOMMENDED THAT TEAMS TRACK THEIR OWN
INVENTORY


Scoring Overview

The 5S Bonus

The
5S Bonus

is awarded at the completion of each match
for maintaining a clean and safe work environment
:



5S Bonus
is calculated at the end of each match but is not
finalized until the end of the round


5S Bonus
will be awarded at the end of a match, if no
game pieces have been removed from play, and any game
pieces in contact with the floor are also in contact with the
robot


The maximum 5S per round
is 10% of the scored amount
