The Game
Game Description
Matches are played on a field set up as illustrated in the figures throughout. The Robot Skills
Challenge and the Teamwork Challenge use the exact same field and set up.
In the Teamwork Challenge, an
Alliance of two (2) Robots, operating under driver control, work
together in each
Match .
In the Robot Skills Challenge, one (1)
Robot attempts to score as many points as possible. These
matches consist of
Driving Skills Matches, which will be entirely driver controlled, and Programming
Skills Matches
, which will be autonomous with limited human interaction.
The object of the game is to attain the highest score by
Scoring Rings on the Floor Goal and on
Posts , by having Uniform Posts , by Emptying Starting Pegs , and by Releasing the Bonus Tray .

Safety Rules
<S1> If, at any time, the Robot operation or Team actions are deemed unsafe or have damaged the
Field Elements or Rings , the offending team may be Disabled and/or Disqualified by the
determination of the referees. The
Robot will require re-inspection before it may again take the
field.
General Game Rules
<G1> All team members, which includes all students and adults associated with a team, are
expected to conduct themselves in a respectful and positive manner while participating in the VEX
IQ Challenge. If team members are disrespectful or uncivil to staff, volunteers, or fellow teams at an
event, the team may be
Disqualified from their current or upcoming Match . Judges may also
consider team conduct and ethics when determining awards.
In all aspects of the VEX IQ Challenge program, the
Students make the decisions and do the work
with adult mentorship. The VEX community prides itself on being a positive learning environment
where no one is bullied, harassed, berated or places unnecessary stress upon students and/or
event volunteers. Stressful and challenging situations are viewed as teachable moments to model
positive behaviors and good sportsmanship.
<G2>When reading and applying the various rules in this document, please remember that
common sense always applies in the VEX IQ Challenge.
<G3>At the beginning of a Match , each Robot must:
a. Only be contacting the Floor .
b. Fit within a 11” x 20” area, bounded by the Starting Position.
c. Be no taller than 15”
An offending Robot will be removed from the Match at the Head Referee's discretion.

<G4> During the Match , Robots may not expand beyond the 11”x20” area they were limited to at
the start of the
Match . However, Robots are permitted to expand beyond the 15” high starting
requirement
. Violations of this rule will result in a warning for minor offenses that do not affect the
match. Major and/or score affecting offenses will result in a
Disqualification . Teams who receive
multiple warnings may also receive a
Disqualification, at the Head Referee's discretion.
<G5>Each team shall include two
Drivers . Teams with only one Student in attendance at an event
are granted an allowance to use a qualified
Driver from the event. No Driver may fulfill this role for
more than one team at any given event.
During a
Match , Robots may only be operated by the Drivers . No Driver shall operate a Robot for
more than thirty-five (35) seconds. The two drivers must switch their controller between twenty-
five (:25) seconds and thirty-five (:35) seconds remaining in the
Match. The second Driver may not
touch his/her team’s controls until the controller is passed to him/her. Once the controller is
passed, the first
Driver may no longer touch his/her team’s controls. Violations of this rule will result
in a warning for minor offenses that do not affect the match. Score affecting offenses will result in
a
Disqualification . Teams who receive multiple warnings may also receive a Disqualification, at the
Head Referee's discretion.
<G6>During a
Match , the Drivers must remain in their Driver Station , except when legally
interacting with their
Robot as per <G15>. Drivers are not allowed to use any sort of communication
devices during their
Match . Devices with communication features turned off (e.g. a phone in
airplane mode) are allowed.
<G7>
Drivers are prohibited from making intentional contact with any Field Element or Robots
during a
Match , except for the allowances in <G15> . Any intentional contact may result in a
Disqualification . Accidental contact will not be penalized, unless the contact directly impacts the
final score of the
Match . This type of accidental contact may result in a Disqualification .
<G8>
Rings that leave the playing field will not be returned to the playing field.
<G9>Scores will be calculated for all
Matches immediately after the Match and once all objects on
the field come to rest. Any
Scoring , Emptying, or Releasing that takes place after the Match due to
Robots continuing to drive after the Match will not count. Referees are not allowed to review any
videos or pictures from the
Match .
<G10>
Robots may not intentionally detach parts or leave mechanisms on the field during any
Match . If an intentionally detached component or mechanism affects game play, the team shall be
Disqualified at the Head Referee’s discretion.
<G11>
Robots may not grasp, grapple, or attach to any Field Elements . Strategies with
mechanisms that react against multiple sides of a
Field Element in an effort to latch onto said Field

Element are prohibited. The intent of this rule is to prevent teams from both unintentionally
damaging the field, and from anchoring themselves to the field. Minor violations of this rule that do
not affect the match will result in a warning. Score Affecting offenses will result in a
Disqualification .
Teams that receive multiple warnings may also receive a
Disqualification at the Head Referee's
discretion.
<G12>
Robots must be designed to permit easy removal of Rings from any grasping mechanism
without requiring that the
Robot have power after the Match .
<G13>Field tolerances may vary by as much as ±1” unless otherwise specified. Teams must
design
Robots accordingly.
<G14> Replays are at the discretion of the Event Partner and Head Referee, and will only be issued
in the most extreme circumstances.
<G15>If a
Robot goes completely out-of-bounds (outside the playing field), gets stuck, tips over, or
otherwise requires assistance, the
Drivers may retrieve & reset the Robot . In the process they
must:
1. Signal the Referee by placing their VEX IQ Controller on the ground.
2. Move the
Robot to a Starting Position .
3. Any
Rings in possession of the Robot while being handled must be removed from the Robot
and taken out of play for the remainder of the
Match .
This rule is intended so teams can fix damaged
Robots or help get their Robots "out of trouble." It is
not intended for
Teams to use as part of a strategy to gain an advantage during a Match . If a Head
Referee sees
Teams strategically exploiting this rule, they may be Disqualified from said Match .
<G16>
Robots are not allowed to remove Rings from the Bonus Tray when it is not Released . Minor
violations of this rule that do not affect the match will result in a warning. Major (score affecting)
offenses will result in a
Disqualification . Teams that receive multiple warnings may also receive a
Disqualification at the Head Referee's discretion.
<G17> Adults may assist Students in urgent situations, however adults should never work on or
program a Robot without Students on that Team being present and actively participating.
<G18> All rules in this manual are subject to changes, and not considered official until August 17th,
2017. We do not expect any major changes to take place; however we do reserve the right to make
changes until August 17th, 2017. There will also be scheduled manual updates on June 15th, 2017
April 5th, 2018. Teams are strongly encouraged to review the VEX IQ Forum for rule updates and
clarifications: www.vexiqforum.com
