BEST Generic Game Rules
GMRK00001 Revision 3; May 2008 1.0 Overview This is a youth oriented contest. The youth will gain the most if they do the work. Mentors and coaches are to provide guidance only and not to make parts, detail design, nor force their will on the youth. The rules governing the BEST competition consist of the following: 1. Game Specific Rules (may supercede Generic Game Rules) 2. BEST Generic Game Rules (this document) 3. BEST Generic Kit Notes 4. Returnable Kit List 5. Consumable Kit List 6. On-line Question and Answer (Q&A) system Most questions about the game can be answered by first READING THE RULES THOROUGHLY. All questions concerning these rules (during the 6-week design and construction phase, not during the competition) must be submitted to the Game Committee in writing through the web-based interface at http://www.bestinc.org. All questions and answers will be distributed to all teams via the web. Responses to the posted questions on the web site are an extension of the rules. In the event of contradiction between the rules and the Q&A responses, the Q&A responses supersede the rules.

2.0 Safety Due to the nature of events in which electrical equipment and tools are used, safety may not and will not be compromised. 1. Safety first. 2. The referees will disqualify any machine that appears to be a safety hazard. 3. Batteries, chargers, and other components of the R/C system may not be tampered with. 4. All drivers and spotters must wear safety glasses (provided at the event) during their matches. 5. Except for a power drill/driver and a soldering iron (or soldering gun), no power tools (including battery operated) will be allowed in the pit area during any BEST activity. Common hand tools will be allowed. The power drill/driver may be used for drilling and/or hardware insertion/removal, but not for grinding, sawing, routing, etc. Power tools are to be operated only in the pit area or in the hub designated workstation area. 6. All individuals working on the machine in the pit area must wear safety gear appropriate to the activity (e.g., safety glasses should be used when soldering or drilling). 7. Any illegal tools may be confiscated for the day. 3.0 Robot Constraints 3.1 Material Constraints Each team receives two kits: a returnable kit and a consumable kit. Each machine must be constructed using only the materials that appear on the returnable and consumable kit lists (provided in separate documents). Exceptions to this rule are described in Section 3.1.3. The Returnable Kit List and Consumable Kit List are the official references for parts; therefore, they define the type and quantity of parts that can legally be used on the machine. The team is responsible for confirming that items in the received kits are consistent with the items on the lists and include no excess parts. Excess parts may not be used. 3.1.1 Returnable Kit 1. Returnable Kit equipment cannot be modified in any way except as noted in items 5, 7 and 8 below. At the end of the contest, the kit must be returned in the same condition as received. 2. The Returnable Kit List specifies certain items that may not be attached to the machine (e.g., the battery chargers). 3. The motors may not be opened for any reason. For example, it is illegal to change the gearing or to re-wind the armature of any motors. 4. The pulleys, bearings, and shoulder screw included in the return kit may not be modified. You may not use any glue or adhesive tape on these items 5. The belt stock supplied in the returnable kit may be modified as needed (e.g., cut, holes punched, etc.); however, the belt that is provided as loop may not be modified. 6. Tape/adhesive/glue may not be applied to any returnable items. The adhesive portion of the supplied VelcroTM brand hook and loop fastener may not be attached to the battery or to other returnable items. The receiver box should have hook-side fastener (applied by BEST) that can be used to mount this part. 7. The transmitter, receiver, servos, BRAIN, batteries, and battery chargers may not be tampered with, modified, or adjusted in any way. The antenna must not be cut or trimmed. Teams may not put labels or rubber bands on the transmitters, nor make internal, reversible modifications to the joysticks. There are two exceptions to this rule: a. Servo horns may be removed from the servos and modified as desired. b. The BRAIN user processor may be programmed as desired. 8. Wires may be soldered to the motor power lugs and to the male connector wires. The male connector wires may be cut and stripped as required to allow attachment of additional wire. 9. The connectors for the BRAIN must be used to connect any wiring to the BRAIN. 10. Only one battery per match may be used. Even if unconnected, the other battery may not be on the machine. 11. On Game Day, replacement batteries will only be provided upon proof of battery failure (e.g., a bad connection) on an exchange basis (you must turn in the bad battery). Please note that there is no excuse for a battery “meltdown”. Batteries should be monitored while they are being charged. 12. You must play all your official games using the batteries supplied by BEST. Team-owned batteries are not allowed on the field or in the pit area on Game Day; however, team-owned batteries are allowed during other BEST activities. 3.1.2 Consumable Kit 1. Consumable Kit parts may be modified as desired within the constraints of these rules. 2. Limited numbers of replacement parts may be available from your local hub, upon a justified request. Otherwise, lost or damaged kit material may only be replaced with identical components. Replacement parts purchased by the team must have the same: a. material as the kit part; b. treatment or grade as the kit part; and; c. dimensions as the kit part. e.g., replacement plywood must be the same grade as the kit material; a 1x4 may not be replaced with a 2x4 of the same total volume. 3. The Consumable Kit includes optional items that may be provided by the team and used on the machine. 3.1.3 Additional Materials & Constraints 1. Lubricants may be used for lubrication only. A machine may not intentionally contaminate the playing field or an opponent's machine with lubricant. 2. Paint, stickers, and/or decals may be added as decorations only, but may not be applied to any returnable items. 3. Other non-functional decorations are permitted as long as they do not aid the machine in performing the game. If you can remove it (and you may be asked to) and your machine behaves the same, it is probably non-functional. Prohibited decorations include: a. strobe lights; b. cameras, c. any device that transmits or receives signals to/from an external device. 4. Non-functional decorations may use a separate power source (e.g., 9V battery). 5. You may solder electrical wire connections using your own solder except where electrical connectors are provided. Where connectors have been provided (i.e., on the BRAIN, servo extension wires, batteries and other returnable items), they must be used without soldering to the connector. Solder may be applied to connectors included in the Consumable Kit (e.g., bullet connectors). 6. No welding, brazing or structural soldering is allowed. 7. Metal, rubber, and plastic items may be heated and reformed, but may not be melted and re-cast. 8. Materials may not be changed chemically. The exceptions are that strings may be singed to prevent loose ends and that resin and hardener may be mixed to result in epoxy. 3.2 Size 1. At the start of each match, the machine must fit, unconstrained, within a cubic space that is 24 inches on a side. The machine must remain within the maximum size limit, unconstrained, until the beginning of the match. 2. Once the match begins, the machine may unfold and change size through its own power. 3. There is no size requirement at the end of the match (i.e., the machine does not have to return to its initial configuration). 3.3 Weight 1. The weight of the machine may not exceed 24 pounds, including the battery and all parts and devices of your machine (e.g., detaching pieces, optional equipment, tethered parts, etc.). 3.4 Energy Sources 1. The energy used by the machine must come solely from: a. electrical energy derived from the single onboard battery pack; b. storage achieved by the deformation of the springs provided in the kit; c. a change in the altitude of the center of gravity of any part of the machine; and/or; d. stretched rubber from the inner tube or the shock cord, provided the part is attached to the machine such that it will not fly off if broken. 3.5 Compliance 1. All machines will be inspected for compliance with the regulations before the competition. Machines must meet these regulations to qualify for the competition. The winning machines may be inspected again following the tournament. Failure to comply with the regulations will result in disqualification. 2. No substitute machines are allowed. Machines may be modified between rounds but must still meet all the regulations after the modifications are made. The compliance official must approve all modifications prior to the next round of competition. 3. Random re-checks of machines will be performed throughout the day at the discretion of the referees. Any machine found to be non-compliant will not be allowed to continue the competition until brought into compliance and may be disqualified from prior matches. 4. The machines may not leave the competition site between the time they are checked in and the start of the competition without approval from the competition officials. 5. Teams that place high enough to advance to a regional competition are allowed to make repairs and/or functional improvements to their machine. Machines will be rechecked for compliance prior to the regional competition. 3.6 General 1. Machines must be designed to operate by reacting only against the surface of the playing field (including the PVC pipes, ramps, etc), the opponents’ machines, and the air. Machines are allowed to clamp to anything in the field except another machine. 2. During a match, the machine may only be controlled through normal operation of the radio control system. Touching the robot will result in penalty or disqualification as described in section 4.3. 3. Machines must prominently display their machine number and the school’s or team’s name or logo. 4. Powered tandem devices are permitted and may use an umbilical to connect the two devices. This umbilical is considered part of the machine and is subject to the same constraints as the rest of the machine. 5. All projectiles must have a frontal area greater than 10 square inches. A projectile is anything launched through the air, whether free flying or tethered. Parts that detach or fall from a machine and remain on the playing surface are not considered projectiles. 6. Gaining traction or gripping game pieces by the use of adhesives, or by abrading or breaking the surface of the field is not allowed. 7. Spiked wheels are allowed only if the portion of the spike in contact with the field has at least one dimension greater than ¼ inch. 8. Strategies aimed only at destruction, damage (e.g., stabbing, cutting, etc.), overturning, or entanglement of an opponent's machine are not in the spirit of the competition and are not allowed. Turning over an opponent's machine may or may not result in a penalty depending on the opinion of the referees. Review section 4.3 for a description of penalties for overly aggressive actions. 9. Placement of blocking devices on the field is permitted, but placement of blocking devices on opposing machines is not allowed. Throwing of nets to capture or contain game pieces is permitted, but using nets to entangle another machine is not allowed. Note that your driving over another team’s net that is on the field does not constitute an attempt by the other team to entangle your machine, even if you do become entangled. 10. Following the contest, all items provided in the Returnable Kit must be returned to the hub (local BEST organization). The rest of the machine may be retained by its respective school. 4.0 Tournament 4.1 General 1. There will be at least five referees during each match. The Head Referee will act as timekeeper and the other four referees will monitor each of the teams. 2. Referees have ultimate authority during the competition. No protests will be allowed. 3. On Game Day there will be individuals identified to answer questions about the game or rules. Do not approach referees (or others) with questions. 4. During the tournament, a maximum setup time of 30 seconds will be allowed once the team arrives at the field. Teams will be notified of their field and position assignment at least two minutes before the match. Teams must be in the staging area at the end of the preceding match. 5. At the start of each match, the machine must be placed at the designated starting area. The spotter or driver may enter the field prior to the start of the match to place the machine in its starting location and prepare it for the match. Temporary alignment marks on the field are not permitted. Additional team members may assist in setting up the machine, but must leave the field area prior to the start of the match. 6. The machine, driver and spotter must be in the designated location(s) at the start of the match to score any points during the match. 7. Spotters and drivers are not allowed to handle the game pieces prior to a match. 8. A maximum of 30 seconds will be allowed at the end of each match for removal of the machines. Additional team members may assist in removing the machine. 9. A referee will untangle machines that become entangled with part of the field for more than 10 seconds or that appear to be damaging the field because of the entanglement. 4.2 Drivers and Spotters 1. During a match, only one student member of each team is allowed in the team driver’s area and one student member is allowed in the team spotter’s area. Adult coaches and teachers are not allowed in either of the areas during matches. Students are not allowed to stand on platforms of their own construction (or each other) to get a better view. 2. Only one person per match is allowed to drive the machine (i.e., operate the R/C transmitter). Prior to the competition, each team must submit a driver list to the organizers. The minimum number of student team members on the driver list is shown in the following table:
Please note that the previous table reflects the minimum number of drivers required; BEST encourages participation by as many team members as possible. Also note that the number of student team members present at the competition is used to determine the minimum number of drivers on the list. 3. The first person on the driver list is the driver for the first match; the second person on the list is the driver for the second match, etc. This rotation will continue for successive matches until the list is exhausted, at which time the rotation will start again at the top of the list. Rotation in successive phases of the competition (e.g., seeding, semi-finals, and finals) will begin where the previous phase rotation left off. If the organizers eliminate a match for any reason, the driver rotation will continue in accordance with the driver list with the driver scheduled for the eliminated match (or matches) being the first driver for the following match. 4. The spotter may be any student from the team. 5. During a match, spotters and drivers may not communicate with anyone through the use of any electronic devices or other signaling technique that involves a signaling aid that is not part of the human body (e.g., signs, sticks, marked gloves, etc. are not allowed).
