VRC Turning Point Referee Training Chapter 4: Tipping, Entanglement, Damage & G12

VRC Turning Point Referee Training Chapter 4: Tipping, Entanglement, Damage & G12

Welcome to the VEX Robotics Competition
referee training videos designed for both referees and teams. This is chapter
4, tipping, entanglement, damage, and G12. Let’s take a look at rule G12.
Strategies aimed solely at the destruction, damage, tipping over, or
entanglement of opposing robots are not part of the ethos of the VEX Robotics
competition and are not allowed. If the tipping, entanglement, or damage is ruled
to be intentional or egregious the offending team may be disqualified from
that match. Repeated offenses could result in disqualification from the
entirety of the competition. Let’s step through each part of this rule. Tipping
and damage are pretty straightforward to notice and define. Entanglement has its
own definition in the Turning Point manual. A robot is entangled if it has
grabbed, hooked, or attached to an opposing robot or a field element. G12 B
states that some incidental tipping, entanglement, and damage may occur as
part of normal gameplay without violation. It will be up to the head
referees discretion whether the interaction was incidental or
intentional. So what does all of this mean? Well when a robot gets tipped over,
damaged, or entangled the referee will need to make a judgment call whether or
not a violation occurred. Remember as a highly interactive game, some incidental
tipping, or damage is expected. To truly be in violation of G12
a robot must intentionally or egregiously tip over an opposing robot,
intentionally or egregiously grab or hook an opposing robot, or intentionally
or egregiously damage an opposing robot. It’s important to only penalize teams
for intentional violations as opposed to incidental ones. For example when a robot
is pushing an opponent and the opponent starts to tip over, pay attention to
whether the pushing robot backs away or continues pushing to force the opponent
over. A team who backs away should not be
penalized for tipping while a team who continues to push should be penalized.
Remember a referee can only judge based off of what they see on the field, not
what they think is going through a team’s head. This is another reason why
clear verbal warnings are critical in these situations to give teams a chance
to back away and avoid jumping straight to a violation. That being said G12c
applies in this situation as well. A team is responsible for the actions of its
robot at all times including the autonomous period. This applies both to
teams that are driving recklessly or potentially causing damage and to teams
that drive around with a small wheelbase. A team should design its robot such that
it is not easily tipped over or damaged by minor contact. For example, it is
expected that many teams might want to expand upwards in order to high score
caps on posts. If your robot tips over backwards every time that you try to
score a cap it’s not likely that an opponent would get a G12 violation for
causing one of these tips. In VRC Turning Point G12
also includes note 1. Alliances who attempt to utilize the center platform
should expect vigorous interactions from opponent robots. When a robot is
contacting or engaging with the center platform incidental damage that is
caused by opponent robots pushing, tipping, or entangling with them would
not be considered a violation of G12. Intentional damage or dangerous
mechanisms may still be considered a violation of R3, S1, or G1 at the head
referees discretion. This is a very important note for referees and teams to
keep in mind this year. The center platform may be a hotly contested area
of the field especially at the end of the match and especially at high levels
of play vigorous interactions are expected here and they are completely
legal. In most cases incidental tipping or damaged from being pushed off of the
center platform will not be penalized. Teams who go for those 6 points at the
end of the match should be aware of the risk that they take in doing so.
Sometimes these interactions may cause incidental damage to other robots on
nearby Alliance platforms. This scenario is covered by note 2, damage caused by indirect contact with the center platform is included in
note 1. So this means that if two robots are engaged in a center platform scuffle
and one of them falls off onto a partner that’s on the Alliance platform this is
OK. there will be no G12 violation called
for this incidental contact similarly if a robot is on the floor
trying to push off a center parked robot and is damaged as a result of this
interaction this is also ok. They accepted that risk when they began
indirectly engaging with the center platform. And finally note 3 explains
that everything we just talked about only applies if the robots are
contacting the center platform. The Alliance platform by itself is not
included in note 1. Robots which are Alliance parked and not contacting or
interacting with the center platform are treated the same as robots that are on
the floor or otherwise playing the game. So if a robot is by itself on the
Alliance platform any tipping or damaged caused to them by opponents would be
considered a G12 violation just like it would be anywhere else on the field. Now
there is a line here between incidental tipping, and combat robotics. R3 which
states that robots may not utilize mechanisms designed to damage or
entangle other robots still applies here. A robot with a mechanism solely designed
to flip opponents, cut their wires, or cause any other forms of extreme damage
would still not be legal. If a referee sees that the center platform contest is
getting a little too dangerous they may issue a verbal warning to the teams
involved or they may ask a team to modify the mechanism in question before
the next match. Pushing matches or scuffles are okay repeated intentional
or egregious damage is not. That’s all for chapter 4, but make sure you check
out the other chapters which explore other refereeing topics.
