Questions and answers will be added to this page as we receive them. For a printable version of all questions and answers, see this document.
Each match is 2 minutes and 30 seconds long.
No. ALLIANCES can strategize to figure out what approach works best for them, whether it is using all four POWER GENERATORS, or only two or three.
A HUMAN PLAYER can only have contact with a POWER LINE CUBE or SOLAR PANEL, they must not touch ROBOTS or FUEL CUBES.
No. Once the HUMAN PLAYER has placed the SOLAR PANEL or POWER LINE CUBE in the LOADING ZONE, they may not touch that game element again.
Yes. As soon as the REACTION PLANT is filled, it will start functioning. If one ALLIANCE chooses to connect their POWER LINE beforehand, as soon as the REACTION PLANT is functioning they will start earning points, whereas if the other ALLIANCE waits to connect their POWER LINE until after the REACTION PLANT is full, they will not start earning points until the POWER LINE is connected.
Yes. As soon as the REACTION PLANT is filled with the eight FULE CUBEs and a VILLAGE has connected their POWER LINE, that VILLAGE will start to receive points. It does not matter which VILLAGE placed FULE CUBEs in the REACTION PLANT. However, keep in mind our values of gracious professionalism and coopertition!
Yes. A ROBOT must completely deliver the item to the VILLAGE POWER STATION by placing them over the edge and releasing control of them.
Yes. A VILLAGE can install all of the POWER LINE CUBES before doing anything else. But for each POWER GENERATOR, teams must connect the POWER LINE for that POWER GENERATOR before FUEL CUBES or turning the WIND TURBINE crank would score points.
Your team is considered not showing up if they do not send at least a team representative. Note: if your team is given a RED CARD for not showing up, the only impact is that you will not receive points for the round. If you send a representative (even without your robot), you will get points for the round based on your other partners’ performance.
No. The ranking and scores from the first rounds will be eliminated before the start of the final round; everyone starts from zero.
The total individual score is the sum of the ALLIANCE’s scores over all rounds of play. Specific team robot scoring will not be tracked.
A green, low-pile carpet.
Please see sheet 3 of the Field Build Guide. The high goal starts at 596mm off the playing field and has a height of 250mm and width of 250mm. The low goal at the playing field level has a height of 296mm and width of 450mm.
Please see rule <G14> ROBOTS may not grab, grapple, or grasp field elements unless otherwise explicitly permitted. This rule excludes game objects but not scoring zones.
No, please review rules G05 and E05. <G05> No outside communication with the DRIVE TEAMS during a MATCH and HUMAN PLAYERS must not directly interact with ROBOTS during the MATCH. This does not mean that HUMAN PLAYERS must be silent, just they can not communicate with ROBOTS or DRIVE TEAMS during the MATCH.
Yes, it does not matter how a ROBOT moves a FUEL CUBE so long as there is no damage to the FUEL CUBE.
Yes, it does not matter how a ROBOT moves a FUEL CUBE so long as there is no damage to the FUEL CUBE.
No, this causes a safety concern.
There will be replacements at the event, located at the Spare Parts station.
Yes HUMAN PLAYERs are part of a DRIVE TEAM, but they also have special privileges such as they get to not be considered under rule <G06> about how DRIVE TEAM is not allowed contact with the PLAYING FIELD during a match. Because of this, the HUMAN PLAYERs are classed differently and cannot communicate with the rest of the DRIVE TEAM during the MATCH.
Yes, DRIVERS can restart the program using the tablet.
Yes, see rule <G04> The CAPTAIN and the DRIVERS must stay in their DRIVER STATION and the HUMAN PLAYER must remain in the human player station they are in when the MATCH begins.
The CUBES are 150mm x 150mm x 150mm.
Yes. There are 5 POWER LINE CUBES available for each ALLIANCE, which is enough to run all of the GENERATORS (COMBUSTION PLANT, REACTION PLANT, and WIND TURBINE), complete the COOPERTITION BONUS, and have one extra. The SOLAR ARRAY does not require a POWER LINE CUBE to activate it.
All FUEL CUBES will be touching the ground in the FUEL CUBE starting location on the PLAYING FIELD at the start on the MATCH.
The exact locations of the FUEL CUBES is not specified. CUBES will be generally evenly distributed within the starting area, but the density is not guaranteed.
The FUEL CUBES can be possessed by any team, and the ownership of the fuel CUBES can be passed between ROBOTS as long as no other rules are broken.
POWER LINE CUBES are not substitutes for FUEL CUBES. Any POWER LINE CUBES placed in locations other than the VILLAGE POWER STATIONS will not be worth any points.
No. Once a POWER LINE CUBE is used to CONNECT one POWER PLANT, it can’t be used to CONNECT an additional POWER PLANT.
Yes. A HUMAN PLAYER is allowed to install the POWER LINE CUBE of the alternate color for the COOPERTITION BONUS. <E07> has been updated for further clarity.
A maximum of three (3) FUEL CUBES (white) or two (2) FUEL CUBES (white) and one (1) POWER LINE CUBE (colored) may be controlled by each ROBOT in a VILLAGE alliance. A Maximum of 9 CUBES can be controlled by the whole ALLIANCE at any one time.
ROBOTS are allowed to launch FUEL CUBES through the air with the intent of scoring. A ROBOT must demonstrate during inspection that a launched FUEL CUBE cannot travel in the air more than maximum a distance of 2.5 m and 1 m in elevation.
Teams are not allowed to launch FUEL CUBES towards any HUMAN PLAYERS or towards the audience. ROBOTS are not allowed to damage FUEL CUBES at any time.
If the referees feel that a ROBOT is launching FUEL CUBES that would cause a safety issue, the team will be asked to redesign their ROBOT and the ROBOT will be required to be reinspected.
The HUMAN PLAYER can INSTALL any POWER CUBE in the specific location for each POWER GENERATOR. If you are standing in VILLAGE DRIVER STATION looking at the field from left to right it the order is COOPERTITION POWER LINE, COMBUSTION PLANT, REACTION PLANT, and WIND TURBINE.
Yes, <E03> Damaged Game objects no longer score. The referees will make the situation based decision on what is considered damage. If a Robot continues to damage fuel cubes Yellow or Red Cards may be issued.
No. <E07> ROBOTS can only interact with POWER LINE CUBES that are the same color as their VILLAGE alliance. We encourage teams to talk to the opposing alliance before the match.
Yes, both POWER CUBES must be in place to get the COOPERTITION BONUS. Nothing happens if only one POWER CUBE is in the opposition’s VILLAGE.
The FUEL CUBE must be fully inside the REACTION PLANT. If someone looks from the side or above the REACTION PLANT the FUEL CUBE is not visible.
An ALLIANCE is made up of 3 teams. Each national team will provide 1 HUMAN PLAYER (3 total). The HUMAN PLAYERS from all 3 teams will choose how to accomplish all of the tasks; 2 in the VILLAGE POWER STATION and 1 in the SOLAR PANEL FACTORY.
Only 5 SOLAR PANELS can be scored in the SOLAR ARRAY. The other SOLAR PANELS are extras.
After each SOLAR PANEL is INSTALLED by the HUMAN PLAYER, without violating E11 and E5, it will produce one (1) kJ per second for the remainder of the game. The SOLAR ARRAY does not need to have all 5 SOLAR PANELS INSTALLED to start generating power from an individual SOLAR PANEL.
There is a limitation of the ROBOT carrying 1 SOLAR PANEL at a time. There is no limitation on the number of SOLAR PANELS that can be in the loading zone or that can be placed in the loading zone by the HUMAN PLAYER, just make sure to follow <E11>. The ROBOT can get the next SOLAR PANEL at any time. For example, if a Robot drops a solar panel when driving, the robot could try and pick it up or go back and grab a different PANEL.
The flat surface of the SOLAR PANEL is 3mm polycarbonate. It is not included in the kit, but using some of the 4mm extruded plastic sheet is an acceptable alternative that will result in similar performance. The screws used to assemble the SOLAR PANEL are the 8mm length M3’s that were included in the kit. Please see the SOLAR PANEL drawing in the Field Build Guide for exact specifications.
No, a HUMAN PLAYER can only place new SOLAR PANELs into the SOLAR PANEL FACTORY.
The WIND TURBINE crank starts vertically aligned, parallel to the post of the turbine. A TEAM cannot change the position of anything on the PLAYING FIELD before a MATCH. If something is not in place, let the referees or field staff know before the MATCH starts.
No. The WIND TURBINE has very minimal resistance. A specific torque won’t be provided, but it should be assumed a force not larger than the weight of the handle is required to move it.
No, it does not matter which direction. But the ROBOT must rotate the crank three full revolutions from where the ROBOT start the rotation of the WIND TURBINE crank.
ROBOTs are remotely controlled using the Fire Tablet sent in the 2018 FIRST Global Kit.
No. The intent of this rule is for a ROBOT to be within a 50cm cubic volume. The rule currently lists all three dimensions of the ROBOT to be a maximum 50cm. There are no additional allowances for length. This does not include soft parts of the robot such as string or zip ties.
No. ROBOTS can be any size after the start of the match so long they follow all other rules. Example: <S01> ROBOTS must stay on the PLAYING FIELD.
No. ROBOTs are not allowed to extend off of the playing field. See rules <S01> and <S02> of the game manual.
No. Each ROBOT may only use one battery at a time on their ROBOT, regardless of if it is electrically connected or not.
No. <R02> states that ROBOTS must be constructed from only the quantity and type of components included in their 2018 FIRST Global kit unless otherwise explicitly allowed. This means only the components inside the Plastic Storage Bin.
No. Teams are not allowed to use the packaging that the parts come in.
Yes. Drilling is similar to cutting and according to <R05> cutting mechanical components is allowed.
Team are allowed to modify according to R05, but need to keeping <R02> in mind. With <R02> robots must be constructed of the type of components sent in the 2018 FIRST Global Kit. Parts must be easily recognized as coming from the 2018 FIRST Global Kit.
Yes, cutting the screw sent in the 2018 FIRST Global Kit is allowed, but please consider using the spacers sent in the kits.
No. Parts must be easily recognized as coming from the 2018 FIRST Global Kit.
No. Teams cannot modify the wires to make them longer. There are four JST VH Motor Power 2-pin wires with a length of 100cm sent in the kit. For the encoder and sensor wires, there are four JST PH Sensor 4-pin wires with a length of 100cm as well. For the encoder wires, there are JST PH 4-pin Joiner Boards that can be used to connect two encoder wires together.
Yes. MARKERS ONLY can be used for aesthetics and labeling purposes. Do not cover up any technical information on the electronics, motors, or sensors. Paint or stickers are not allowed.
No. <R04D> does allow for small amounts of tape (preferably electrical tape) to be used for securing wires.
No. Teams can have up to 200 zip ties. <R04B> is for replacing zip ties.
The white 4mm Thick Corrugated Plastic Sheets (2018 FIRST Global Kit part number: REV-41-1630) is a robot building material that your team can customize. There are four (4) sheets, size 480mm x 355mm, of the corrugated plastic.
No. There are no specific advantages to using one programming language over another. Just like in the real world of engineering, it is the end result that matters more than the method, as there will always be more than one way to solve a problem.
See other Q&A on ROBOTs controlling FUEL CUBEs and POWER LINE CUBE. In addition, <E08> allows each ROBOT to control one (1) SOLAR PANEL of the ROBOT’s VILLAGE ALLIANCE color.
See page 7 of the Game Manual for the definition of CONTROL.
No. Teams cannot have more than what is in the 2018 kit. This rule is so teams can get replacements and wording of <R04>A has been updated.
Any commercially available M3 screws and nuts that are the same lengths as in the 2018 FIRST Global Kit may be used, but this is to replace any screws and nuts that go missing, not to increase the number of screws and nuts used in a ROBOT.
No. Teams are only allowed to use the quantity and types listed in 2018 FIRST Global Kit.
The REV Smart Robot Servo, sent in the 2018 Robot kit, has the ability to be both a position and continuous rotation servos. The Servo can be switch between modes using an SRS programmer, also sent in the kit. Please see the SRS Programmer User’s Manual from the REV Robotics website for instructions on switching the servo modes.
Yes, <R05> does state that cutting mechanical components such as extrusion, brackets, screws, chain, hook and loop, cords, etc. is allowed.
Yes, cutting would be considered modification. Teams cannot cut the motor shaft.
No, teams must use the Amazon Fire Tablet sent in the kits.
No, only the controller sent in the 2018 FIRST Global Kit.
