Safety Manual
Section 3.5.5 Charging and Handling
• Do not short out the battery terminals. If metal tools/parts contact the terminals simultaneously,
it will create a direct short circuit. This may cause high heat to develop in the battery
terminal/part/tool area and the battery could explode. To avoid the possibility of shorting out the
battery terminals and creating a hazardous situation it is required to cover all exposed battery
terminals and connections with appropriate non-insulating material such as electrical tape or
tubing.
It surprises us that we feel the need to say this, please don’t put the POWER CUBE cover on
anyone’s head and zip it closed; also, don’t eat it.

Game and Season Manual
Section 1.8 Question and Answer System
The Q&A is not a resource for
• rulings on hypothetical strategies or vague situations,
• challenging decisions made at past events, or
• a design reviews of a ROBOT system for legality.
The responses in the Q&A do not supersede the text in the manual, although every effort will be
made to eliminate inconsistencies between the two. While responses provided in the Q&A may be
used to aid discussion at each event, per Section 10.6 REFEREE Interaction and Section 9
Inspection & Eligibility Rules, REFEREES and Inspectors are the ultimate authority on rules. If you
have concerns about enforcement trends by volunteer authorities, please notify FIRST at
firstroboticscompetition@firstinspires.org.

Weak questions are overly broad, vague, and/or include no rule references. Some examples of
questions that will not be answered in the Q&A are:
• Is this part/design legal?
• How would should the a REFEREE have ruled if when this specific, hypothetical game play
happened?
Good questions ask generically about features of parts or designs, gameplay scenarios, or rules, and
often reference one or more relevant rules within the question. Some examples of questions that will
likely be answered in the Q&A are:
• A device we are considering using on the robot comes with purple AWG 40 wire, does this
comply with R?? and R??
• We’re not sure how to interpret how Rule G?? applies if Blue Robot A does X and Red Robot
B does Y, can you please clarify?
Section 3.1 Zones and Marking
STARTING LINE: a line of 2 in. (~5 cm), white gaffers tape that runs the width of the carpet and is 2
ft. 6 in. (~76 cm) behind the ALLIANCE WALL diamond plate, which includes the tape.
Section 3.3 SCALE
A cable protector extends from the center of each side of the PLATFORM and is 2 ½ in. (~6 cm) wide
and ¾ in. (~2 cm) high (Electriduct, Inc. CSX-3, black). The cable protector is attached to the field
with hook fastener, increasing the height to approximately ⅞ in. (~2 cm). These cable protectors
extend to the GUARDRAILS and the SWITCHES.
Section 3.4.1 SWITCH PLATES
The PLATES are 9 in. (~23 cm) above the carpet when the SWITCH is level. Like the SCALE, the
SWITCH tilts and rests in different positions based on the placement of POWER CUBES. During the
MATCH, the SWITCH is in one of three (3) two (2) states based on the magnitude of its tilt:
1. OWNERSHIP by the Red its ALLIANCE, or
2. OWNERSHIP by the Blue ALLIANCE, or
3. neither ALLIANCE has OWNERSHIP
If the outside edge of an ALLIANCE’S colored PLATE is positioned between 3 in. (~8 cm) and 6 in.
(~15 cm) above the FIELD carpet then the ALLIANCE has OWNERSHIP of the its SWITCH. If the
outside edge of an ALLIANCE colored PLATE is positioned between 12 in (~30 cm) 6 in (~15 cm)
and 15 in. (~38 cm) above the FIELD carpet then the opposing ALLIANCE has OWNERSHIP. When
neither ALLIANCE has OWNERSHIP of the SWITCH, the outside edges of the PLATES are between
6 in (~15 cm) and 12 in. (~30 cm) above the FIELD carpet. See Figure 3-15. The time required to
move between states is dependent on the weight difference and the distribution of the weight on the
SWITCH PLATES. Details on OWNERSHIP can be found in Section 4.2 Scoring.

Section 3.8 POWER CUBE
POWER CUBES may be purchased from AndyMark (am-3818 and am-3741), Innovation First (217-
6188 and 217-6193), and Rev Robotics (REV-21-1217 and REV-21-1218). Please note that due to
the use of recycled material in the manufacturing process, the batches of crates will vary slightly in
color, but not such that it’s perceptible with the cover in place.
Section 4.1.2 MATCH Setup
Prior to the start of each MATCH, POWER CUBES, elements used to affect the position of the
SCALE and SWITCHES and earn POWER UPS, are staged as shown in Figure 4-1. Staging details
are as follows:
A. Seven (7) in each PORTAL (on the carpet between the PORTAL wall and the STARTING
LINE), minus any preloaded POWER CUBES,
B. Six (6) next to each SWITCH. They are arranged approximately equidistant from each other
along the face of the FENCE closest to the SCALE, FIRST logo facing up
C. Ten (10) located in each ALLIANCE POWER CUBE PILE (in a pyramid formation, with six on
the bottom, three in the middle, and one on top, justified toward the SWITCH, FIRST logo
facing up)
Section 4.2: Scoring
The primary method of earning points in FIRST® POWER UPSM is by placing POWER CUBES on the
PLATES of the SWITCH or SCALE to establish OWNERSHIP. OWNERSHIP is a state of the
ALLIANCE’S SWITCH or SCALE where it is tilted in favor of an ALLIANCE colored PLATE, such that
the outside edge of the ALLIANCE colored PLATE is at or less than a specified height above the
carpet. ALLIANCES earn points when OWNERSHIP is established and additional points for each
additional second of OWNERSHIP.
…
An ALLIANCE has OWNERSHIP of their SWITCH when:
A. the SWITCH is tilted in favor of their ALLIANCE colored PLATE, such that the outside edge
of the ALLIANCE colored PLATE is at or less than 6 in. (~15 cm) from the floor for at least
one (1) second, or
B. they have played the FORCE POWER UP at level 1 or 3 (see Section 4.3 POWER UPS)
The Blue ALLIANCE’S SWITCH accumulates points for the Blue
ALLIANCE when the PLATE illuminated and pulsing with blue lights is
down.
The SWITCH does not accumulate points for either ALLIANCE when
the blue PLATE is above 6 in (~15 cm).
An ALLIANCE has OWNERSHIP of the SCALE when:

4 of 6
A. the SCALE is tilted in favor of their ALLIANCE colored PLATE, such that the outside edge of
the ALLIANCE’S colored PLATE is at or lower than 4 ft. 8 in. (~142 cm) from the floor for at
least one (1) second and there isn’t an active opponent’s Level 2 or 3 FORCE, or
B. they have played the FORCE POWER UP at level 2 or 3 (see Section 4.3 POWER UPS)
Note that points for the SWITCH and SCALE are accrued over time and
not a direct function of the number of POWER CUBES placed on the
SWITCH or SCALE.
Points are not taken away when OWNERSHIP changes, but rather stop
accumulating (if balanced) or start accumulating for the opposite
ALLIANCE if they take OWNERSHIP of the SCALE.
Note from the FRC Director on the edits to Table 4-1:
You will see we added a requirement in Table 4-1 requiring a ROBOT to not be in direct contact with their
PLATFORM to be considered CLIMBING. We believe this was already a requirement, given our
BUMPER rules, but adding the requirement in Table 4-1 was the most straightforward way of making this
clear.

Note from the FRC Director on the edits to Table 4-2:
These changes are an attempt to clarify how BOOST works. They do not significantly change the
points being earned under BOOST.

Section 8.3 ROBOT Safety & Damage Prevention
R07. Protrusions from the ROBOT and exposed surfaces on the ROBOT shall not pose hazards to
the ARCADE elements (including the POWER CUBES GAME PIECES) or people.
If the ROBOT includes protrusions that form the “leading edge” of the
ROBOT as it drives and have a surface area of less than 1 in.2 (~6 cm2),
it will invite detailed Inspection. For example, forklifts, lifting arms, or
grapplers may be carefully inspected for these hazards..
Section 8.6 Motors & Actuators
R33.
For servos, note that the roboRIO is limited to a max current output of
2.2A on the 6V rail (12.4W of electrical input power). Teams should
make sure that their total servo power usage remains below this limit at
all times.
This is the total number of each motor a Team may use on their ROBOT,
not the quantity per part number. For example, each team may use up to
six (6) CIM motors on their ROBOT, regardless of the quantity or
combination of each individual part number used.
Given the extensive amount of motors allowed on the ROBOT, Teams
are encouraged to consider the total power available from the ROBOT

battery during the design and build of the ROBOT. Drawing large
amounts of current from many motors at the same time could lead to
drops in ROBOT battery voltage that may result in tripping the main
breaker or trigger the brownout protection of the roboRIO. For more
information about the roboRIO brownout protection and measuring
current draw using the PDP, see roboRIO Brownout and Understanding
Current Draw.
