VEX Starstruck Competition: How To
Play the Game (Rules and Regulations)
Definitions and Terminology:
●
Alliance – A pre-assigned grouping of two teams that
work together for a given Match.
●
Alliance Starting Tile – A colored tile (red or blue),
that designates the location where Robots must start the match.
●
Alliance Station – The designated region where the
Drive Team Members must remain during their Match.
●
Autonomous Period – A 15-second (0:15) time period at
the start of the match when the Robots operate and react only to sensor inputs
and to commands pre-programmed by the team into the onboard Robot control
system. Winner of the autonomous round will be granted bonus points.
●
Cube – An orange cube shaped cloth Scoring Object
filled with pillow type filling, with a side length of 12.5” ± 1”. Each Cube
weighs 1.68 lbs ±15%
●
Drive Team Member – Any of the three (3) Students
allowed in the Alliance Station during a Match for each team. Only Student
Drive Team Members are allowed to touch the controls at any time during the
Match, interact with the Robot as per , and interact with Scoring Objects as
per . Adults are not allowed to be Drive Team Members.
●
Far Zone – One of two (2) areas, one (1) for each
alliance, in which teams can Score Scoring Objects. The Far Zones are defined
by the inner edges of the playing field walls and the designated tape lines on
the foam field tiles. The Alliance’s Far Zone is across the Fence from their
Alliance Station. Note: The Hanging Bars are not part of either Far Zone.
●
Fence – The 24” high PVC foam extrusion structure which
divides the playing field in two halves. It also marks the boundary between the
two Near Zones.
●
Field Element –
The foam field tiles, field perimeter, Fence, and all supporting structures.
●
High Hanging – A Robot is considered to be High Hanging
if it is touching the Hanging Bar of its own color and completely above the
infinite plane parallel to the foam field tiles, formed by the top of the field
perimeter. A Robot that is touching the field perimeter is not considered to be
High Hanging. Note: A High Hanging Robot does not also count as a Low Hanging
Robot. Only one (1) Alliance Robot can earn points for Hanging (High or Low)
during a Match.
●
Low Hanging – A Robot is considered to be Low Hanging
if it is touching the Hanging Bar of its own color and not touching any foam
field tiles. Note: Only one (1) Alliance Robot can earn points for Hanging
(High or Low) during a Match.
●
Match – A Match consists of an Autonomous Period
followed by a Driver Controlled Period for a total time of two minutes, (2:00).
●
Near Zone – One of two (2) areas one (1) for each
alliance, in which teams can Score Scoring Objects. The Near Zones are defined
by the inner edges of the playing field walls, and the designated tape lines on
the foam field tiles. The Alliance’s Near Zone is across the Fence from their
Alliance Station. Note 1: The Fence is not part of either Near Zone. Note
2: The tape lines between the Near and Far Zones is considered to be in
both Zones. The tape lines at the edge of the Near Zone, closest to the Fence are
not considered to be in any Zone..
●
Preload – The four (4) Stars, one (1) for each team,
that must be placed on the field such they are touching its Robot, not touching
any grey foam tiles, and fully within the field perimeter prior to each Match.
●
Scored – A Scoring Object is Scored in a Zone if it
meets one of the following criteria:
1.
The Scoring Object is touching the Zone a. If a Scoring Object is touching
multiple Zones it is Scored in the higher point value Zone
2. The Scoring
Object is not touching any Zone and is Supported by a Robot and/or a Scoring
Object, it is Scored in the Zone that Robot or Scoring Object is touching. a.
If the Robot and/or Supporting Scoring Object in this situation is touching
multiple Zones, the Supported Scoring Object is Scored in the highest point
value Zone b. If a Scoring Object is Supported by a Hanging Robot the Scoring
Object would be Scored in the Far Zone adjacent to the Hanging Bar that the
Robot is Hanging from.
Note
1: If a Scoring Object is solely Supported by the Fence it is not Scored in
any Zones.
Note
2: If a Scoring Object is Supported by two opposing Robots it is not Scored
in any Zones.
Note
3: If a Scoring Object is touching two opposing Zones is not Scored in any
Zone.
●
Star – A yellow
foam Scoring Object consisting six (6) points extending from a common center,
with an overall diameter of 14”. Each Star weighs 0.60 lbs ±15%.
Safety Rules:
1.
If at any time the Robot operation or team actions are
deemed unsafe or have damaged the Field Elements or Scoring Objects, by the
determination of the referees, the offending team may be Disabled and/or
Disqualified. The Robot will require re-inspection before it may again take the
field.
a. Teams should be extra cautious
when interacting with Scoring Objects. Damage such as large scuffs and/or
punctures can be ruled as a violation of.
2. If a Robot goes completely
out-of-bounds (outside the playing field), it will be Disabled for the
remainder of the Match. Note: The intent is NOT to penalize Robots for
having mechanisms that inadvertently cross the field border during normal game
play.
Robot Rules:
<R1> Only one (1) robot
will be allowed to compete per team in the VEX Robotics Competition. Though it
is expected that teams will make changes to their robot at the competition, a
team is limited to only one (1) robot. As such, a VEX robot, for the purposes of
the VEX Robotics Competition, has the following subsystems:
Subsystem 1:
Mobile robotic base including wheels, tracks, legs, or any other mechanism that
allows the robot to navigate the majority of the flat playing field surface.
For a stationary robot, the robotic base without wheels would be considered
Subsystem 1.
Subsystem
2: Power and control system that includes a VEX legal battery, a VEX control
system, and associated motors for the mobile robotic base.
Subsystem
3: Additional mechanisms (and associated motors) that allow manipulation of
game objects or navigation of field obstacles.
Given
the above definitions, a minimum robot for use in any VEX Robotics Competition
event (including skills challenges) must consist of 1 and 2 above. Thus if you
are swapping out an entire subsystem of either item 1 or 2, you have now
created a second robot and are no longer legal.
a.
Teams may not compete with one robot, while a second is being modified or
assembled.
b.
Teams may not switch back and forth between multiple robots during a
competition. vex.com Copyright 2016, VEX Robotics Inc. 2016-08-16 24
<R2> Every robot will be
required to pass a full inspection before being cleared to compete. This
inspection will ensure that all robot rules and regulations are met. Initial
inspections will take place during team registration/practice time.
a. If
significant changes are made to a robot, it must be re-inspected before it will
be allowed to compete.
b. All robot configurations
must be inspected before being used in competition.
c. Teams may be
requested to submit to random spot-inspections by event personnel. Refusal to
submit will result in disqualification.
d. Referees or
inspectors may decide that a robot is in violation of the rules. In this event,
the team in violation will be disqualified and the robot will be barred from
the playing field until it passes re-inspection.
a. Those that could
potentially damage playing field components.
b. Those that
could potentially damage other competing robots.
c. Those that
pose an unnecessary risk of entanglement.
<R4> At the beginning of
any match, robots must be smaller than 18” x 18” x 18”.
a. During
inspections, robots will be measured in one of two ways
i. Robots will be placed into a “sizing box”
which has interior dimensions matching the above size constraints. To pass
inspection, a robot must fit within the box without touching the box walls or
ceiling.
ii. Robots will
be sized using a VEX Robotics Competition Robot Sizing Tool. Robots will be
placed on a flat surface and must not touch the measurement slide as it is
passed over the surface. Please see http://www.vexrobotics.com/vex/products/competitionproducts/vrc-products/276-2086.html
for a visual reference.
b. Robots may
expand beyond their starting size constraints after the start of a match.
c. Any
restraints used to maintain starting size (i.e. zip ties, rubber bands, etc.)
MUST remain attached to the robot for the duration of the match.
