23 – Robotics

• A Component’s Collection providing mechanical / electrical / control hardware to

the Provincial winner that is required for the ‘Built On-site Autonomous Robot

Competition Element’ at the National Event in Halifax, NS.

Judging Criteria:

On the court performance of the robots in the set tasks.

Team Size:

FOUR (4) Students will be allowed to compete at the Provincial Event. However,

only TWO (2) students will be allowed to compete at the National Event in Halifax,

NS.

Provincial Event:

There will NOT be an Autonomous task at the BC Provincial Event. It will strictly

feature the Tele-Operated challenge outlined in this scope document.

National Event:

The Team that wins at the Provincial Event will participate in BOTH the

Teleoperation and the Autonomous Competition Element’s on BOTH Competition

Days in Halifax. Autonomous task is outlined at the end of this scope.

Definition of terms referenced in this document:

• Tele-Operated Robot Elements are elements under the direct/active control of

competitors during game play through the use of one or two radios/game

controllers held by the courtside competitors

• Mobile Independent Autonomous Mobile Robot Elements are elements that at

the start of a game have a competitor pressing their start button or enter on a

computer keyboard as the only competitor to Independent Autonomous Mobile

Robot Element communication during the entire game.

• Stationary Independent Autonomous Elements are elements that have their

power on at the start of games but have no direct contact with a competitor

during game play. These units may interact with the team’s tele-operated

mobile robot with the actions of the tele-operated mobile robot triggering an

active response by the Independent Autonomous Element which may be

managed either by a mechanical based system (e.g. A series of limit switches /

no programmed elements) or a pre-programmed system (e.g. Managed by an

Arduino or other microprocessor) internal to the Independent Autonomous

Element.

Tele-Operation Game Description: The 2019 Skills Canada Robotics Challenge includes two teams competing against each other to attack their opponents Citadel and defend their own. Each Team prepares to dual in the following ways:

• Shoot ammunition at the Citadel to weaken it.

• Shoot ammunition at the opponents

• Remove all ammunition from their arsenal.

• Climbing the Citadel hill Each match is 3 minutes in duration. During this period, robots are controlled by student drivers and work to score as many points as possible. The core game situation requires a Robot or Robots to deliver Soft Golf Balls into their Opponent’s Nets.


23 – Robotics

Field Setup: The Court Playing Surface will be a 16ft by 16ft square.

Note: Depending on the overall floor space allocated for Robotics in Halifax it is possible that the Court Playing Surface may be reduced to a 12ft by 12ft square at the National Competition.

The Perimeter Court walls will be made up of 2x4 in planks laying on edge. This wall will as a result be approximately 3.5in tall. The Court Surface may vary between melamine, concrete, hardboard, plywood or the Facility Floor. Detailed Court Information has been included in the Appendix Section of this document. Please note: Although great pains will be made to keep the court in compliance with the drawings, some inaccuracies in construction may occur. Please make your robot designs allowing for a possible 1/2in tolerance. Exclusive Area: Each team is permitted to solely operate in their Exclusive Use Court Area which is one half of the court (approximately 8ft by 16ft), divided by a Center Wall.

Teams have Exclusive Use of a 30in wide passageway along the perimeter of their Exclusive Use Court Area. Both Team members can be active in and move unrestricted throughout this Exclusive Passageway during game play. Team members may not cross the infinitely tall imaginary vertical plane that the Center Wall of the court creates and extends into their Exclusive Passageway on both sides of the court.


23 – Robotics

Competitors may not enter an opponent team’s Assigned Courtside Team Area at any time during game play. It is a Team Decision what roles team members will fill. Drivers are the competitors holding the robot controller and asserting direct control over a Tele-operated robot.

The Spotter would be the competitor providing navigational guidance to the driver. Competitors may change roles while a game is in progress.

Citadel Hill: Each team will have their own Citadel located along the center of the back wall of the court. Two (2) Stationary Nets are positioned at the Front Corners of the Citadel hill with the net opening fixed facing forward towards the opponent’s Citadel. The base of Citadel Hill is 36in by 48in. The top is 26in by 28in and is 4.5in above the court floor. There are Five (5) steps leading to the top of the Citadel Hill. Each of these steps has a 0.75in Rise and a 2in Run. The “Tall” Fish Nets are positioned at the Right and Left front corners and on the forth(4th) step of the Citadel Hill. These are called the Citadel Goals.

The nets used for the Citadel Goals that will be used at the competition will be: Lucky Strike LS Econ Boat Net - Canadian Tire - Product # 78-4053-6, $15.99


23 – Robotics

On top of the citadel is located One (1) “On the Citadel Hill Ball Box”. This box is fixed in place and CANNOT be moved by robots during game play. The “Citadel Hill Ball Box” is 15in by 7in by 0.75in tall. There are Eight (8) Ammunition Rounds randomly placed in each Citadel Hill Box at the start of the game. There is a 4ft by 8ft by 0.125in Hardboard Wall centered behind the Citadel Hill mounted to the Court Perimeter. The purpose of this backboard is to limit the amount of Ammunition leaving the court when being shot by the opponent. Ammunition: Teams will have use of Thirty (30) Soft Practice Golf Balls which will be used as Ammunition Rounds. At the start of the match, the team may be in possession of up to Six (6) Ammunition Rounds. If a team opts to not pre-load any or all of the six (6) Ammunition Rounds, they will be randomly placed in the “On the Citadel Box”. An additional Twenty-four (24) Ammunition Rounds are available to the team in Three (3) storage boxes positioned in their Exclusive Use Court Area.


23 – Robotics

• Eight (8) Ammunition Rounds will be randomly placed in Two (2) “On the Court Floor Boxes” located on the court floor along the center wall. Both “On the Court Floor Boxes” are Fixed in place and CANNOT be moved by the robots during game play. The “On the Court Floor Boxes” are 15in by 7in by 0.75in tall.

• Eight (8) Ammunition Rounds will be randomly placed in the “On the Citadel

Hill Box” which is affixed to the top of the teams own Citadel Hill and CANNOT be moved during game play.


23 – Robotics

Robots MUST be on top of their own Citadel Hill when they are retrieving balls from the “On the Citadel Hill Box”. This means that no part of the retrieving robot is in contact with the Citadel Hill steps or Net and is fully supported by the upper surface of the Citadel Hill Platform. Ammunition that hits the Backboard and bounces back into the Court area is still playable. Ammunition that hits the Backboard and exits the playing area of the court is no longer in play and will not be returned to the game. Any Ammunition that has left the playing area will have a scored value of NULL (0). The Soft Practice Golf Balls that will be used at the competition will be: PrideSports Practice Golf Balls, Foam, 12-Count, Yellow

Game Rules: Games will involve Two (2) Teams at a time. One team in each half of the court called their Exclusive Use Area. Teams can utilize a Maximum of Two (2) Tele-Operated Robots and a Maximum of One (1) Independent Autonomous Element. The entire Team entry (all team elements that are on the court) must fit into the overall size limitation at the beginning of the game. Teams may expand to a greater volume once the game has started. A Team’s entire entry (all Robot Elements) MUST be positioned ON TOP of their own Citadel Hill at the start of the match. Teams may be in possession of up to a total of Six (6) Ammunition Rounds at the start of the Game. (e.g. if two robots… 3 rounds in each, 6 total). Each Team’s robot CAN be in possession of an Unrestricted number of Ammunition Rounds at any time once the match has started. Robots CAN shoot/fire/deliver Ammunition Rounds into ANY net from anywhere in their own Exclusive Use Area. A robot may NOT enter into their opponent’s Exclusive Use Area.

• Touching the Court Floor in Opponent’s Exclusive Use Area is considered entering.

• Extending beyond 6in past the Center wall is considered entering an Opponent’s Exclusive Use Area.

• Momentary breaking the Infinitely tall vertical plane the center wall creates is not considered entering an Opponent’s Exclusive Use Area.

Teams can incorporate defensive or offensive strategies. However, Teams may NOT assert control over balls in their opponent’s Exclusive Use Area.

• A robot may NOT physically take possession of or move Ammunition Rounds that are located in their Opponent’s Exclusive Use Area. This includes but not limited to:

o Reaching over the center wall o Using an Air Flow to move Ammunition Rounds

Teams CANNOT intentionally remove Ammunition from the playing area.

• Ammunition that has been aimed at a net and has missed the target, going out of play does not constitute intentional removal of Ammunition. It will be the discretion of the court referee if a shot was an intentional removal or a missed shot.

Mobile Goal(s) mounted on Robots must be able to move freely in a 360-degree rotation at ALL times during game play.

Robot Rules and Restrictions: All elements of a team’s entry, both Autonomous and Tele-Operated Robots must pass a pre-competition inspection for compliance with the safety and design rules before they will be allowed to participate in tournament games.

o Note: Robots must remain in compliance with these rules throughout the competition. If teams fall out of compliance with these rules then they will not be permitted to compete and will forfeit all of their scheduled games until they have corrected the problem.

Teams must mount a Trout Net on all Tele-Operated robots. The mount must be non-articulated and in a vertically fixed position for the entirety of the match. The mount must be:

o Made up of a 5in long, 1.5in Diameter ABS Pipe that has an End Cap closing off the bottom of the pipe.

o Positioned at the Mid-point along the backside of the robot. o The Bottom of the Net Holder must be 8 inches above the court floor when

the robot is sitting in its normal position on the court floor. o Able to allow the net fully rotate 360 degrees AT ALL TIMES during match

play.

The Net Holder and the structural supports required to hold it in place WILL NOT be included when calculating a Robot’s Overall Size. Damaging the court area is prohibited. If a robot’s design causes damage to the court elements, then it will not be allowed to compete until it can operate without causing damage. Games missed due to this situation will be forfeited.


23 – Robotics

o NOTE: Damage is considered to be BREAKING court components. Robots bumping into court components and causing them to shift position without breaking any court element will NOT be considered to be damaging the court. It is expected that all court components will be fixed firmly in place so that the court is a Neutral Factor in the competition.

Overall Team Robot Entry Size: Complete Team Entries must not exceed an overall size of 4 cubic feet (6,912 cubic inches) at the start of each match. Team entries may expand to a larger size once a game has started. Overall Team Entry Size will be calculated by using the maximum single dimension in each category (Length / Width / Height) of the Complete Team Entry not average dimensions. This overall size maximum will allow Team Entries to be any variation / combination of elements that does not exceed 6,912 cubic inches, using the following formula: Volume = Length x Width x Height Start of the Match Robot Status: When a robot’s main power is turned on prior to the start of a game the robot must be in an overall ‘Idle State’ and the following conditions must exist:

• Robots must be stationary

• Robots must be in their designated-on Top of their Citadel Hill starting location.

• If Team Entries involve multiple Robots / Mechanisms then all of them must be placed in the designated starting location and must be positioned to not exceed the allowed total 4 cu ft. volume per Team.

• All systems may be ON.

• Air System Circuits may be fully charged to 100 PSI and their compressors can be ON.


23 – Robotics

Power Sources / Management: The total voltage in any individual circuit cannot exceed 24 Volts. The maximum continuous power rating allowed in any circuit branch is 240 Watts, which will be limited by voltage and fuse selection. A larger main fuse can be used to provide protection for motor controllers. To calculated power in any given circuit, use the following formula: Power (Watts) = Voltage (Volts) x Current (Amps)

Teams are reminded that it is the purpose of a fuse to protect the students themselves and the equipment in their circuits. Teams must develop circuit diagrams, and calculate the appropriate values for all circuits on their robot. Teams must submit a wiring diagram of their robot’s circuits. Each current branch path from the battery must include either an in-line fuse, resettable fuse, circuit breaker, or be connected to a dedicated fuse in a rack. Vex Cortex systems are exempt from this rule as they are already in compliance.


23 – Robotics

Batteries must be complete sealed commercial battery packs. It is the competitor’s responsibility to have the correct battery charger for their battery chemistry. Teams should have a LiPo safe bag when charging LiPo batteries. All Robots must be able to be turned off with a single motion. Robot Controller Receivers may be in an independent circuit. Non-Electrical (Battery) Energy Sources: Pressure based energy sources (air or other) may be pre-charged to a MAXIMUM of 100-PSI pressure in their reservoirs (cylinders and tanks) at the start of each game. Air Pressure systems using Competitor-made or modified air pressure hardware are NOT permitted. All pressurized tanks on robots must have a pressure gauge to indicate the stored pressure and a form of automatic overpressure safety relief system. The pressure tanks and related gauges / controls must be shielded from damage due to collisions or flying target objects. The stored pressure in the tank must not exceed a maximum of 100-PSI at any time. Tension-based energy sources (elastics, springs, or other) may be in either a relaxed at rest state or in a tense / compressed state at the start of each game. Recommended Robot Controllers: It is recommended (not required) that all teams use 2.4 GHz “non-crystal” control systems on Tele-Operated Robots. Teams are allowed the use of an unlimited number of channels, but only two (2) separate Tele-Operated Robots. Teams assume full responsibility if any interference is to occur with their respective communication systems that could render the robot(s) useless. Tele-Operated Robots may not transmit audio / visual information to off the robot devices. (Ex: Having a camera transmit images real time to a computer near the driver, etc) Pit Area: A pit area is provided so that the students may make repairs and improvements to their robots between matches. The pit area and contest court may be available to teams to work or practice during lunch breaks if a Technical Committee Member is present.


23 – Robotics

Competitors MUST wear safety glasses when doing fabrication work involving material removal processes (grinding / cutting). Only registered robot competitors are permitted in the contest space Designated Teacher / Industry Advisor are permitted in the pit area ONLY to help load in supplies and inspect the worktable setup of their team prior to the start of the competition. Designated Teacher / Industry Advisor / Coach / Mentor / Parent are NOT allowed in the pit area during the competition. These individuals are NOT permitted to handle tools or robot parts. Student Competitors must complete all repairs and modifications on their robot. Teams will be provided with a pit area workspace on a standard project table. It is required that teams fabricate a tabletop stand for holding their robot(s) in the pit area. This stand or these stands should hold the robot(s) securely and be capable of preventing the robot(s) from driving on or off the table in the case of either deliberate motor testing during repairs or due to random, unexpected motor activity.

Tournament Rules: Competitors must wear Safety Glasses when they are in the Tele-Operation Court Area. Dueling Citadels Game Tournament will be seeded using a ‘Round Robin Tournament Format’. Highest seed will be determined by the following priority:

• Highest number of wins

• Highest number of overall accumulated points throughout the Round Robin

• Highest number of Ties

• Number of Games Played Teams will participate in an equal number of Round Robin matches. Depending on the number of participating teams, an attempt will be made for each team to play each other opponent team at least once. After the Round Robin, a Seeded Double Elimination Playoff will commence. Playoff games will last 2 minutes. There cannot be a tie in a playoff match for the playoffs to continue. If a tie exists after a playoff match, a 2-minute Re-Match will be played. If a tie exists a second time, a Tie-Breaker Match will be played. See details in the Tie-Breaker Section. The amount of time between games will be determined by the number of participants. This information will be provided to teams at the start of the tournament. Between tournament games, battery changes and repairs to robots may be completed at the team’s assigned Pit Area Worktable. During match play, referees will have ultimate authority over game rulings, and will have full authority over team conduct in the court and pit area.

Matches will start on time. Teams are responsible to know when their matches are scheduled. Teams arriving late will be allowed to use the remainder of the time in the match. Competitors cannot enter onto the court surface or adjust their robot during a match. If a robot is mal-functioning and represents a hazard to participants, other robots or itself in the opinion of the Referee, then, the referee may stop the clock, and may authorize the shutting off of the robot during a game. Disabled robots or parts of robots not generating any safety concerns will be left on the court until the game time expires.


23 – Robotics

At the start of a match, robots are expected to be in their Designated-ON top of their Citadel Hill Starting Positions and within the overall size restriction. Robots arriving AFTER a game has started will be allowed to enter the game and use the Time remaining in the match. Robots must not leave the contest court at any time during a match. It will be a referee’s ruling that decides if an ‘End of the Game Shot’ or a “Citadel Climb” took place before or after the game-ending buzzer sounded. If a Soft Practice Golf Ball lands out of the court, it may not be retrieved and will be out of limits of play. If intentional, a 3-point penalty will occur.

Scoring will take place after the End of the Game Buzzer

Tie-Breaker Situation (Playoffs only):

In the event that a match has scored in a tie twice, a Tie-Breaker Game will be

played. In a Tie-Breaker Game, there is a time limit of thirty (30) seconds. Robots

will only have the six (6) Ammunition Rounds that they are allowed to be in

possession with at the start of the match. The match will be scored after the thirty

(30) seconds, the team with the highest score wins. The Tie-Breaker Game will

repeat until a winner has been determined.


23 – Robotics

National Event: Autonomous Task Competitors will be provided, at no cost to the teams, with a kit distributed to them through their provincial/Territorial office. The autonomous robots must be disassembled on arrival. A description of the Competition Component Collection will be posted on the Skills/Compétences Canada Website. Competitors will build on-site Autonomous Robots using the provided common set of components that they have received from their Provincial/Territorial office. Competitors will demonstrate their robot’s performance in a court to be defined at the Skill area. At the orientation meeting, Competitors will be told the specific Robot Behaviors their Built On-Site Robots need to complete. The suggested performance items listed below reflect the type of core isolated robot performance elements competitor robots will need to complete

• Follow wall perimeter,

• Navigate a maze,

• Navigate around obstacles,

• Follow a colored tape line on the floor,

• Locate and touch an object

• Pick up a small object and move it to a new location

Competitors MUST understand the list above represents samples ONLY and does not present a final or complete list of the potential robot behaviors they might be asked to create. Teams need to develop an understanding of the performance capabilities of ALL components in the Competition Collection and prepare to be able to use any of these components effectively. Competitors need to be prepared to go beyond the initial single stage performance requirements to multi-stage performance requirements as the culminating end of the competition experience. Build On-Site Autonomous Tasks Equipment: Competitors will be required to build their autonomous robot solutions using ONLY the contents of the provided to all teams 2019 Skills Canada Component Collection.
