Competition Rules

The 2018 Rah Cha Cha Ruckus will follow the 2018 FIRST POWER UP Rules.

While we feel that FIRST has done a fantastic job with creating a rule book to satisfy every FIRST team, there are a few rule changes that we feel could enhance the game play at this off-season event.  The rule modifications which will be used at Ruckus are below.

There will be a drivers meeting Saturday morning where any questions can be asked to the head referee. Please refer to the 2018 FIRST Power Up Rules for any rule clarifications first. Thank you!


*** Rule changes for 2018 are now finalized below!


Rule Modifications

In the rule modifications below, text that is underlined represents Ruckus-specific additions to an existing game rule.

Robot Weight

<R05> is changed as follows:

<R04> The ROBOT weight must not exceed 120 125 lbs.

Reasoning: Robots will be given a 5 lb. weight allowance beyond that allowed in the FIRST Power Up official rules in acknowledgement that teams may have had to, or will need to, make repairs to their robot that may put them just over the weight limit. All other portions of this rule remain unchanged and in effect. 



The SCALE PLATES (see manual section 3.3.1) has the following additional information:

The SCALE PLATES on both the SWITCHes will configured with lighting as described in the manual. The lighting on the SCALE will be installed in the base of the SCALE itself and not in the SCALE PLATES (as was seen at most FRC Regionals and Championship events).

In the event of a failure to any of this lighting, ARCADE STAFF will be positioned outside the ARCADE to indicate the appropriate color assignment of the SCALE PLATE with the failed lighting using either a RED or BLUE flag held stationary in the air. If using this flag-based system is necessary, POWER UP use and scale/switch OWNERSHIP will not be indicated by the flags (only color assignments of the plate will be indicated).

Additionally, if lighting does fail and the backup flag-based system is employed, every attempt will be made to create a similar situation for both RED and BLUE ALLIANCES from that point forward.

Reasoning: The movement of the SCALE lighting from the SWITCH PLATES to the SCALE's base is necessary for protection of this sensative electronic equipment. The flag-based backup system has been created and explained because the lighting resources available to off-season events are limited and we feel it important for teams to understand how this event will handle a situation in which all lighting resources have been exhausted.


Real-Time Scoring

Real-time scoring will be employed at Ruckus as with traditional FIRST events. However, we wish clarify operation of the real time scoring as follows:

Any failure of real-time scoring will not be considered an ARENA FAULT provided that the real-time scoring inaccuracies are able to be corrected to the satisfaction of the HEAD REFEREE and field support staff upon conclusion of the MATCH.

Reasoning: While POWER UP Real-time scoring has been relatively reliable at official and off-season events, but on extremely rare occasions issues do arise. We wish to strike a balance that is both fair to teams in terms of competition play, but at the same time make reasonable allowances for failures or human errors that have no or very limited impact on the strategic play of the game and that do not severely change the end result of the game.


Game Pieces

Game pieces employed at Ruckus will be the same as normal events however, we wish to clarify the following:

Game pieces used at Ruckus will be "used" and as such will not be in pristine condition. While we will do our best to use pieces which will not seriously impact team play, teams should expect some variation in game pieces, primarily in POWER CUBE cover condition

Robots repeatedly damaging game pieces and/or field elements through sloppy or extremely aggressive game play should expect to draw attention of referees, resulting in DISABLE per <G19>. Repeat violations will quickly escalate to issuance of YELLOW or RED CARDs per <T03>.

Reasoning: Due to limited availability of this year's game pieces, we will have a limited quantity of spare game pieces on hand; robots causing damage to field elements will be required to correct the situation before being allowed to compete in future MATCHes.


Alliance Selections and Playoffs

ALLIANCE selection and assignment of teams to PLAYER STATIONS will follow the FIRST Championship rules under Section 10.11.1 of the POWER UP Game Manual. In brief, this means that ALLIANCEs will be comprised of 4 teams each and that the ALLIANCE CAPTAIN may choose which teams play in a MATCH and what their PLAYER STATION assignment is on the field. For reference, these are the specific rules from Section 10.11.1 of the game manual:

ALLIANCE selection process: ALLIANCES will be selected per the process as described in Section 10.5.1 ALLIANCE Selection Process, however the process will continue with a 3rd round of selection as follows:

Round 3:The same method is used for each ALLIANCE CAPTAIN’S third choice except the selection order is reversed again, with ALLIANCE One picking first and ALLIANCE Eight picking last. This process results in eight (8) ALLIANCES of four (4) Teams each.
Team Assignment for MATCH Play: ALLIANCES may start with any three (3) of the four (4) ROBOTS on their ALLIANCE during Subdivision RuckusPlayoff MATCHES. The list of three (3) Teams participating in the MATCH and their selected PLAYER STATIONS is called the LINEUP. One representative from the Team not on the LINEUP is allowed as a sixteenth ALLIANCE member. This additional representative may only serve in an advisory role, and will be considered a COACH (e.g. can’t be a HUMAN PLAYER).
LINEUP submission process and LINEUP change rules: Refer to <T11>, <T12>, and <T13> in the game manual for specific detail on how LINEUPs are declared and under what situations they may be changed. Ruckus will use these rules as-is (substitute "Subdivision Playoff" for "Ruckus Playoff").

Reasoning: With the size of this year's event we feel that having 4-team alliances will both engage more teams in the playoff tournament and provide for more competitive play. The added benefit is the removal of variability in backup team availability that we often see at off-season events. Based on overwhelmingly positive feedback from doing this at 2017's Ruckus, we believe this should facilitate a more enjoyable and competitive experience for all teams.
