Rules and Resource Update #4

Jake Lehrman

9 January 2019

  1. If a robot is in its depot and possesses two minerals, it does not count as possessing a third if the robot accidently hits a mineral already in the depot

  2. A team marker falling off the robot does not count as being launched, and thus is not awarded a penalty

  3. If the opposing alliance is scoring in their depot, and not in their landing zone, it is legal to drive under to lander to reach their crater, and not considered blocking since no robot of the other team is trying to reach the lander

  4. If a robot accidentally drops a mineral onto a robot of the opposing alliance, the robot on which the mineral is dropped now possesses the mineral and will count as a penalty if the robot already possesses two minerals

  5. When the match has begun, the drive team captain may move around inside their alliance station in order to talk to their alliance partner, as long as it doesn’t interfere with the scoring referee and field personnel

  6. A robot applying pressure to the side of an the crater rim doesn’t count as grabbing the crater and thus does not violate any rules

  7. Launching game elements only applies when the elements are outside of the robot; minerals may be moved around inside the robot

29 November 2018

  1. No updates to game manuals

  2. If a gold mineral is dragged out of its sample place and then caught underneath the robot at a later point, the alliance still scores the 25 points, despite the mineral being in contact with the robot

  3. Penalties may be given out to any robot that ,even accidentally, removes more than 2 minerals from the crater

  4. The robot is allowed to lean against the lander while supported by the lander bracket

  5. Using wheels to help guide the robot down the lander counts as incidental contact and is thus legal

  6. If the robot is only attached to the lander, with virtually no other types of contact, is legal

  7. The outside edge of the crater rim is the boundary for marking inside and completely inside the crater

  8. Robots are allowed to be rested on other objects as long as it’s easily removable

  9. If part of the robot (for example the earm) is over the crater boundary at the end of the match, the robot is considered “partially” in and will receive partial points

  10. A team marker that uses stored mechanical energy to launch itself from the lander to the depot does not receive an additional 15 points

  11. The team marker can not be rolled, it must be placed without a noticeable horizontal launch

  12. Team markers with wheels are only allowed if the marker disengages from the robot in the depot

  13. Robots are allowed to park in the crater during the autonomous period

  14. A single mineral may knock of both of their alliances gold minerals during autonomous

  15. The team marker is counted as scored or not the moment it becomes stationary

  16. If a robot places its marker in the depot but it is knocked out by their alliance partner before the end of autonomous, it still counts

  17. If the above situation occurs and the alliance partner successfully places their marker in the depot, the depot is considered fully claimed

Rules and Resource Update #2

9 October 2018

  1. A critical update has been made to the navigation targets to correct a scaling issue on two of the images.

  2. A robot may control or possess a maximum of two minerals at a time. However, due to the density of minerals within the crater, robots may temporarily exceed this limit while collecting minerals that are in the Crater. Robots are required to shed excess minerals before performing any other gameplay activities. Within the crater, plowing through any quantity of minerals is allowed but herding or directing multiple minerals beyond the allotted maximum to gain a strategic advantage is not allowed.

  3. Robots in a crater are not eligible to score minerals. Violations of this rule will result in a minor penalty per offense. Additional occurrences of violations of this rule will escalate to yellow cards quickly.

  4. Robots may not obstruct another robot’s path of travel in the area between the lander and a crater for more than 5 seconds. If a referee determines this rule is violated, the offending alliance will receive a minor penalty for every five seconds that they are in violation of this rule. This rule only applies during the driver-controlled period.

  5. The robot main power switch must control all power provided by the robot main battery pack. FIRST requires teams to use either the TETRIX (part # W39129), MATRIX (part # 50- 0030), or REV (REV-31-1387) power switch. The robot main power switch MUST be mounted or positioned to be readily accessible and visible to competition personnel. A main robot power label must be placed near the main power switch of the robot.

  6. UVC compatible cameras are allowed for computer vision-related tasks. It is recommended that UVC compatible cameras be connected to the robot controller through a powered USB hub that is in turn connected to the robot controller through an OTG adapter.

13 September 2018

  1. Before the match, the robot must be completely latched to the lander support bracket on their alliance’s specific side. The lowest point on the robot and team marker may not be any closer than 4 inches to the floor.

  2. Alternatively, the robot must be in the landing zone within the vertical projection of the lander support bracket. A portion of the robot must be below the bracket. The robot cannot start in the opposing alliances landing zone.

  3. Once the robots are either latched or deployed and the autonomous programs have been initialized, the referee will signal the drive team to tell them that once the robot is set, drive teams may no longer touch the robots until the conclusion of the match.

  4. Additionally, drive teams may no longer touch their driver stations or controllers until the autonomous period has ended, except to start the autonomous program.

  5. Prior to the match, two silver and one gold sample will be randomly placed in each sampling station.

  6. The autonomous period in which robots are controlled by a preloaded autonomous program, lasts for thirty seconds and starts at the countdown of a timer.

  7. During the autonomous period, robots that begin on the lander may lower themselves onto the playing field. Each robot that is in contact with the floor and the lander earns 30 points.

  8. .
  9. Additionally, each robot that successfully places their team marker in their alliance’s depot earns 15 points. You are not allowed to launch, shoot, or throw the marker into the depot, only place it.

  10. If a depot is claimed, then minerals cannot be taken from the depot by the opposing alliance during the driver-controlled period.

  11. Each robot parked in a crater at the end of an autonomous period earns 10 points.

  12. At the end of the autonomous period, each sample field that has its gold mineral out of the corresponding taped area and the 2 silver minerals remaining in place will earns 25 points for the alliance that moved the gold mineral.

  13. Minerals that are placed in depot or cargo hold during the autonomous period are scored the same way they are during the driver-controlled period.

  14. Following the autonomous period, each alliance has 5 seconds plus a 3 second countdown to prepare their driver stations for the driver-controlled period.

  15. During the drive-control period, minerals placed into an alliances depot earn 2 points each. Minerals removed from an alliances depot deduct 2 points each.

  16. Gold minerals placed in the gold cargo hold in the lander earn 5 points.

  17. Silver minerals placed in the silver cargo hold in the lander earn 5 points.

  18. Gold minerals in the silver cargo hold and silver minerals in the gold cargo hold are considered contaminants and are worth 0 points.

  19. To be considered scored, a mineral must be completely in the area defined by either the depot or the cargo hold.

  20. The last 30 seconds of the driver-controlled period are called the end game. Driver-controlled period scoring can still take place during the end game.

  21. At the end of the game, each robot that deployed during pre-game or in the course of game play and is latched into either of their alliance’s specific lander support brackets at the end of the match scores 50 points.

  22. Each robot that is parked in any crater at the end of the match earns 25 points.
