2 You should have... World Class Robot Game document Field Setup, Rules, Missions Robot Game Rulings Instructions for construction of Mission Models Spare parts to replace misplaced pieces References on a tablet work very well, especially for model instructions Watch the robot game YouTube video - Sources USFIRST dclass MA FLL Referee page

3 General Match Flow (1) Verify table setup and models thoroughly before first match, quickly before each match. Mat against south wall, centered east-west. Use tape to flatten mat if it is excessively curled. Fields are imperfect, what cannot be cured must be endured All 17 objects in base (verify before team leaves table) Team comes to table, next team on-deck Team sets up quickly, quick check for prohibited equipment (extra motors, controller, robot) Attachments can stay in base, field edge, on side table Team thumbs up, countdown/buzzer to signal start of match, all tables start together Robot starts fully in base (to line edges,12 high), wires too! Warn team if not in base, don t let them start. Robot started with a single touch (NO guiding) No clock stopping, match lasts 2.5 minutes Teams accomplish missions in any order or combination Referee watches closely to assure all conditions met for scoring and all rules followed Only active robot can fulfill a mission, goes dead when touched, robot expected to return to base while active Freely handle robot and cargo inside the base

4 General Match Flow (2) Free hand recovery if robot still in base (no tethers) Penalty for hand recovery (marker, free after 8 used) Cargo brought from base returned to team if in control, cargo from field has to cross line with active robot Robot pieces that fall off robot by accident are returned to team, no penalty No reset of mission models moved by robot! (exception: loose ball can be removed) Field damage no score can result if the field is damaged in the process Any cargo or combined group of cargo being moved to base must cross line into base itself (not just the robot)! At buzzer for end of match, everything stops (no scoring counts after) Scoring at end of match - can un-score accomplished missions during the match Verify missions accomplished with team at table, they initial sheet (only the two at table, NO COACHES!) Disputes go to head referee for final decision Verify that they have not taken any mission models!

5 Potential points for Head Referee - coaches meeting Introduce self Most important keep to schedule! critical to for matches and judging Be on-deck Setup quickly Thumbs up for refs to show ready Start fully in base, single touch start (no guiding) Penalty objects for grabbing robot out-of-base, ask ref to reach robot if team can t Only two team members at table at any time (tell ref if you will be tagging in) - except for repair emergencies No resetting models or clearing robot-caused field damage After match don t touch field until scoring complete Review your missions accomplished with ref and initial your sheet only two at table If disagree and can t settle, ask for the head ref (final) Team gets benefit of doubt (ref s doubt, not yours) Only math or entry errors can be challenged after this Don t take mission models from the field!

6 Competition Table Setup Proper mat placement: pulled flush with south wall, centered between east and west walls. Door fastened to wall just north of double east-west parallel lines Fasten string guides at line markers Otherwise, use duallock markers on mat as guidance When taping mat, use thin black tape (electrical works) and keep to black borders Setup and reset, verify placements and push dual-lock firmly down Tape this corner Our thanks to the TechBrick team for the excellent field graphics (techbrick.com)

7 Home base contents 1 Blue ball Sports mission 2 Mini-figures Apprenticeship mission 12 LEGO pieces (2 sets of 6) Reverse Engineering mission 1 Loop Project-based Learning mission 1 Robot key Robotics Competition mission 17 pieces in total Also must account for all loops on the field at match end Our thanks to the TechBrick team for the excellent field graphics (techbrick.com)

8 World Class Missions 14 missions during the World Class season Missions are attempted in ANY order, combined or not Penalty for recovering robot by hand (ref can reach if requested by team, can t guarantee no damage from handling) Missions only scored at end, but scoring conditions need to be observed during mission) Mission model cannot be fastened to each other or another object, OK to group loosely (exception for apprenticeship model). New Gravity rule: If the robot is about to move a mission model from Base, you must be able to pick that model up and have NOTHING come with it (only do this if asked).

referee keeps account by obvious placement of these penalty markers in some manner

23 Penalties BAG06_eng.pdf If a Robot, Sprawl, or Junk penalty earned (as described in the Rules), the referee keeps account by obvious placement of these penalty markers in some manner as to stay out of the way of you and your robot Robot, Sprawl, or Junk Penalty: -10 EACH Max Penalties Of These Types = -80 Cargo Penalty: Loss Of Cargo

24 Robot and Junk Penalties defined A Robot penalty is given for retrieving the robot by hand when it is completely out of base. A Junk penalty is given at the end of the match for each strategic object abandoned outside Base. A strategic object is a piece placed by the purposely placed by the team, not meant to be a permanent part of the robot. A piece broken from the robot can be returned to the team w/o penalty.

25 Sprawl Penalty defined Sprawl Penalty [Match End-Based] occurs at match end if either: Robot s max dimension is obviously greater than twice the (S/N) width of Base. Strategic object extends out of Base obviously farther than the (S/N) width of Base. Sprawl Penalty [Hand- Based] occurs whenever you either: Touch the robot while its max dimension is obviously greater than twice the (S/N) width of Base. Touch a strategic object while it extends out of Base farther than the (S/N) width of Base.
