On June 15th, 2021, Version 0.2 of the VRC Tipping Point Game Manual was released, and the following changes were made:

  1. Added 2 notes to rule SG2, clarifying “point-to-point” expansion. (An additional graphic will be added to this rule as part of the Manual Version 1.0 update)

Note: This is intended to be a linear, horizontal, “point-to-point” limit, measured across an expanded Robot. It is not a 3D volume, and it does not “rotate” with the Robot if the Robot tips over.

Note 2: If a Head Referee is uncertain whether a Robot has momentarily expanded beyond this limit, they may ask the Team after the Match to replicate the Robot’s state and check for compliance using a tape measure, VRC Expanded Sizing Tool, or other linear measuring device.

  1. Updated Rule R18 to clarify that Robots must use VRC-legal pneumatic components.

Robots may use a V5 Robot Brain, up to eight (8) V5 Smart Motors, and a legal VRC pneumatic system.

  1. Updated the definition of Mobile Goal Base and Figure 15 to include the black, lower part of the Goal.

The 7-sided plastic bottom of a Mobile Goal with a maximal diameter of 13” (330.2mm). Rings may be Scored in the “bowl” of a Mobile Goal Base for points. Both the yellow, blue, or red “upper” portion, and the black “lower” portion, are considered parts of the Mobile Goal Base.

  1. The Scoring section of Appendix B was updated to correct a contradicting rule.

A blue Alliance Mobile Goal that ends the Match in the red Alliance Home Zone is not worth any points. However, it would still receive the points for any Rings which are Scored on / in it.

  1. Various small typo corrections

The next manual update, Version 1.0, will occur on June 29th, 2021.

On June 29th, 2021, Version 1.0 of the VRC Tipping Point Game Manual was released, and the following changes were made:

  1. Updated the definition of Balanced to fix a contradiction with Rule SG3.

As stated in rule SG3, a Platform which is being contacted by an opposing Alliance Robot at the end of a Match automatically results in a DQ for the opposing Robot and / or Alliance, regardless of the above criteria.

  1. Added a Note and Red Box to Rule G12 to clarify interaction with a Robot possessing a Neutral Mobile Goal.

Note

Incidental damage that occurs due to interaction with a Robot which is Possessing a Neutral Mobile Goal will, in most cases, not be considered a violation of G12. Intentional damage, tipping, or dangerous mechanisms may still be considered a violation of R3, S1, or G1 at the Head Referee’s discretion.

Red Box

VRC Tipping Point is intended to be an offensive, interactive game. Robots interacting with Neutral Mobile Goals should expect vigorous interactions from opponent Robots, especially if attempting to interact with multiple Mobile Goals at once.

  1. Added a Red Box to Rule G13 to clarify offensive / defensive roles of Robots.

The following “rules of thumb” apply when determining offensive / defensive roles in the context of rule G13:
-A Robot in Possession of its own Alliance Mobile Goal is generally playing an offensive role.
-A Robot in Possession of an opponent’s Alliance Mobile Goal is generally playing a defensive role.
-A Robot in Possession of a Neutral Mobile Goal is generally neither playing a defensive or offensive role.
In the case of a destructive interaction between two Robots competing for the same Neutral Mobile Goal, G12’s Note will apply.

  1. Added a graphic to Rule SG2 to further illustrate “point-to-point” expansion.

  2. Updated Rule SG3 to prevent Scoring Objects from causing interference with the opposing Alliance Platform during the last thirty (30) seconds of a Match.

Per SG10, using a Scoring Object to cause interference with the opposing Alliance’s Platform during the last thirty (30) seconds would be considered a violation of this rule.

  1. Changed Rule R8e to allow rope / string no thicker than 1/4” (6.35mm).

  2. Updated Appendix A to allow shorter standoffs for Platform construction.

  3. Updated Appendix B to introduce the recommendation, and eventual requirement of VEX GPS Code Strips for all Programming Skills Matches.

  4. Added a new definition of “Additional Electronics” in Appendix C.

Additional Electronics - Any sensor, processor, or other electronic component used in Robot construction, and connected to the V5 Robot Brain, that is not sold by VEX Robotics. Examples could include both commercially-available devices (e.g. Raspberry Pi) or custom devices designed and fabricated by the Team. See VUR10 for more details**

  1. Updated Rules VUR1, VUR9 and VUR1 in Appendix C to clarify use cases of Additional Electronics.

  2. Various minor typo corrections.

The next manual update, Version 1.1, will occur on July 27th, 2021.

On July 27th, 2021, Version 1.1 of the VRC Tipping Point Game Manual was released, and the following changes were made:

  1. Updated the definition of Alliance Home Zone to be a 3-Dimensional volume.

• The Alliance Home Zones are defined by the inner edges of the playing field walls and the designated white tape lines.
• The tape is considered to be part of the Alliance Home Zone.
• The Alliance Home Zones are a 3-dimensional volume, defined by the infinite upward projection from the foam tiles inside of the Alliance Home Zone boundaries.
• The Platforms are considered part of their respective Alliance Home Zone.

  1. Updated Scoring Note 3 to allow any part of the Mobile Goal Base to break the plane of an Alliance Home Zone and be considered as Scored.

A Mobile Goal is considered Scored in an Alliance Home Zone if, at the end of the Match, any part of the Mobile Goal Base is at least partially within the Alliance Home Zone (i.e. “breaking the plane” of the Zone).

  1. Added Scoring Note 6 to clarify additional scoring situations.

Contact with foam tiles, Platforms, and / or Robots does not affect whether a Mobile Goal is considered Scored. Contact is only relevant when determining whether a Mobile Goal is Elevated (see the definition of Elevated for more information). In this particular example, the Mobile Goal would not be considered Elevated, but would still be considered as Scored.

  1. Added another image to G19 to clarify starting orientation of Mobile Goals.

The rotation of Scoring Objects may vary from nominal to ±20°. Rings should always be oriented such that the “raised” portions are parallel to the Platforms. Mobile Goals should always be oriented such that the vision target found on the “point” of the heptagon Base resembles Figure 22.

  1. Updated rule SG3 to clarify penalties for contact with the Platform

• Violations of this rule which do not interfere with gameplay, such as bumping into the Platform and then driving away, will result in the opposing Alliance receiving credit for one additional Elevated Robot at the end of the Match. (Alliances may still only receive points for a maximum of two Elevated Robots).
• Violations of this rule which do interfere with gameplay, such as preventing a Platform from becoming Balanced, will result in a Disqualification, regardless of whether the interference was Match Affecting or not.

  1. Updated rule SG4 to include all Scoring Objects completely within the opposing Alliance Home Zone.

During the Autonomous Period, Robots may not contact the foam tiles, Scoring Objects, Robots, or Platforms which are fully contained in the opposing Alliance Home Zone.

  1. Updated rule R8 to include rubber bands and pneumatic components.

• Rubber bands that are identical in length and thickness to those included in the VEX V5 product line (#32 and #64)
• Pneumatic components with identical SMC manufacturer part numbers to those listed on the VEX website

  1. Updated rule T6 to clarify that the Red Alliance always places Robots last.

The red Alliance places last.

  1. Removed Live Remote Skills from Appendix B

  2. Various minor typo corrections.

The next manual update, Version 2.0, will occur on August 31st, 2021.

On August 31st, 2021, Version 2.0 of the VRC Tipping Point Game Manual was released, and the following changes were made:

  1. Changed the value of the Autonomous Bonus to 6 points.

  2. Updated Scoring Table 3 and the definition of Autonomous Win Point to clarify that Rings can be scored on or in Mobile Goals to receive credit for the Autonomous Win Point.

An Autonomous Win Point is awarded to any Alliance that has Cleared their AWP Line, and Scored at least one Ring on or in each Alliance Mobile Goal, at the end of the Autonomous Period.
The winner of the Autonomous Bonus receives a six (6) point bonus. In the case of a tie, both Alliances receive a three (3) point bonus.
When determining the Autonomous Bonus, Mobile Goals and Rings should both be considered Scored at the end of the Autonomous Period exactly the same as they would be at the end of the Driver Controlled Period.

  1. Updated Scoring Table 3 to clarify that Platforms are not to be included when scoring the Autonomous Bonus.

The Platform should not be included in this scoring calculation (i.e. no additional points are received for Elevated Mobile Goals and/or Robots at the end of the Autonomous Period).

  1. Updated the definition of Platform to include only polycarbonate and PVC.

The 53.0” x 20.1” (1,346.2mm x 511mm) hinged polycarbonate device and the attached red or blue PVC pipes, located in each Alliance Home Zone, that sits 9.5” (241.5mm) high off of the ground when Balanced. The Platform is attached to a double hinge that allows it to tip towards the field in either direction.

  1. Updated SG3c, and added a “red box” to clarify intent.

Per SG10, using a Scoring Object to contact the opposing Alliance’s Platform during the last thirty (30) seconds would be considered a violation of this rule. Placing a Scoring Object underneath the opposing Alliance’s Platform, such that it inhibits the opposing Alliance’s ability to utilize the Platform during the last thirty (30) seconds, would also be considered a violation of this rule.
The intent of SG3 is to prohibit Alliances from directly inhibiting their opponents’ ability to utilize the Platform at the end of a Match. Teams partaking in any gameplay near their opponent’s Platform, especially if manipulating Scoring Objects, should be cognizant of this risk and may receive verbal warnings for doing so. Conversely, Teams attempting to invoke an edge-case SG3 call on their opponents should also be cognizant that it is not feasible for a Head Referee to track the exact movement of every Scoring Object throughout an entire Match. If a single Ring has incidentally found its way underneath a Platform during standard Match gameplay, it will be at the Head Referee’s discretion to determine whether a violation of SG3 has occurred or not

  1. Updated SG9 to account for objects being deflected back into the field.

During the last 30 seconds of the Match:
-Any Scoring Object that leaves the field will not be returned.
-If a Scoring Object is leaving the Field (as determined by the Head Referee), but is deflected back into the field by a Drive Team Member, field monitor, ceiling / wall, or other external factor, it should still be considered “out of the field” and removed by a scorekeeper or Head Referee. If the redirection occurred due to contact with a Drive Team Member, it will be at the Head Referee’s discretion whether G9 or SG9 should apply.

  1. Updated R6 to clarify Cortex product line legality.

Electronics from the VEX Cortex control system are not permitted. This includes the VEXnet Joystick, VEXnet Partner Joystick, VEX ARM® Cortex-based Microcontroller, VEXnet Key 1.0 and 2.0, 2-Wire Motor 393, and any other electronic components which are not compatible with the VEX V5 system.

The next manual update, Version 2.1, will occur on December 7th, 2021.
