2. Description The object is to design and build a robot capable of performing certain tasks on a prescribed playing field.

3. Materials Each team may enter only one robot The robot is to be controlled remotely by radio control, infrared, or by a control box with wires leading to the robot. Batteries used in the controller shall be as stipulated by the manufacturer without modification.

4. Materials Controllers constructed by the competitors shall be powered by commercial batteries not exceeding a combined voltage of 9.6 volts.

5. Materials All robot motion must be powered only by electrical, elastic, or gravitational energy. These forms of energy may not be converted to other forms such as hydraulics, pneumatics, or fluidics to power the robot.

6. Materials Each robot circuit must be energized by one or more commercial batteries which do not exceed 9.6 volts. If multiple batteries are used, they may be connected in series or parallel as long as the voltage output does not exceed 9.6 volts. The voltage stated on commercial batteries will be accepted.

7. Materials Each robot function (such as drive train, arm, etc.) may have its own independent circuit, source of electrical energy, and control mechanism. The robot must have a legible team name on it.

8. Materials At the start of competition, all portions ofthe robot (including the antenna if applicable), with the exception of the wires to the control box(es), must fit into a Plexiglas qualifying cube with inside dimensions of 30 cm x 30 cm by 30 cm.

9. Materials The walls and lid of the qualifying cube may not be used to hold any portion of the robot within the qualifying dimensions.

10. RC Requirements The following frequencies are permitted: 75 MHz band (75.41 through 75.99 MHz) 27 MHz band ( 26.995 thru 27.255 MHz) 49 MHz band (49.8302 thru 49.890 MHz) 2.4 GHz Band (including Bluetooth)

11. RC Requirements Not permitted Frequencies requiring a license Will not be permitted to compete

12. Playing Field Shall be constructed on a piece of ¼ inch thick Masonite® (tempered hardwood) 4 feet by 4 feet, placed on the floor, smooth side up. Students may not step on or stand on the playing field.

13. Playing Field The perimeter will have a border of commercial 1” x 2” (nominal ¾” x 1 ½” actual) wood, attached to the top surface of the field with the 2” dimension placed vertical.

14. Playing Field The field will be equally divided into square zones labeled A, B, C, and D counterclockwise. Zone D will have a border of commercial 11/16” quarter round molding separating it from Zone A and two 11/16” quarter round moldings forming a half cylinder separating it from Zone C.

15. Playing Field Other interior boundaries will be drawn with a fine tipped marker. Zone A will contain the starting position for the robot. Zone B will contain all of the scorable items at the start of the competition.

16. Playing Field All materials for the event, including the playing field, qualifying cube, goals (plastic containers), golf balls, C-cells, Legos® (2 blue and 2 yellow), and United States coins totaling $0.40 value, will be provided by the Event Supervisor.

17. Playing Field Event Supervisor will place the following objects in Zone B (as shown in the playing field diagram): 4 golf balls 4 C-cells 4 Legos® blocks (standard 4x2 size) 2 yellow and two blue U.S. coins totaling $0.40 value

18. Playing Field Zone D Goal Box (Large) Zone B 2 ft by 2 ft Starting position of Robot Zone A 2 ft by 2 ft Zone C 2 ft by 2 ft Zone D 2 ft by 2 ft Golf Balls (4) Standard 2x4 Lego Blocks (4) C-Cell Batteries (4) Location(s) of $0.40 total worth of coins Zone C Goal Box (Small)

19. Coins Coins will be placed in one to four stacks at the midpoints of the diagonals in Zone B. The denominations and arrangements of the coins will be determined by the Event Supervisor at each competition. Arrangement will be announced after impound and will remain the same throughout the competition.

20. Playing Field The large goal in Zone D will be an empty, approximately 10 cm x 10 cm x 12 cm, 1 quart plastic container with no top, bottom intact, and no label. The wall thickness of the container, including the lip, will be less than or equal to 2 mm. The goal can will be placed on its side in the outside corner of Zone D with the open top facing Zone A.

21. Playing Field The small goal in Zone C will be an empty, approximately 10 cm x 10 cm x 8 cm, 1 ½ pint plastic container with no top, bottom intact, and no label. The wall thickness of the container including the lip will be less than or equal to 2 mm. It will be placed in the outside corner of Zone C, lying on its side, with the open “top” facing Zone B.

22. Competition All robots and control systems must be impounded prior to competition and will be retained until the last team has finished competing. Robots and controls of teams that have filed an appeal will be retained by the Event Supervisor until the appeals process is completed.

23. Competition Before starting competition, students will place their robot in the designated starting position in the outside corner of Zone A.

24. Competition Students will place the qualifying cube over the robot. A removable lid and/or visual inspection will be used to ensure the robot height is within the specification. If the robot does not fit, the robot will be allowed to compete but will be ranked behind all qualifying robots.

25. Competition After this, the students may not touch their robot until their run is completed. The students will then remove the qualifying cube. After the qualifying cube is removed, the robot may not change in size or shape or move until the competition begins.

26. Competition Competition will start by having the Event Supervisor verify that the students are ready and then counting aloud “1, 2, 3, go”. Teams will be allowed 3 minutes, starting with the word “go” to complete the task of moving the scorable objects into scoring areas.

27. Competition Competition will stop and scoring terminated when any of the following occur: Three minutes have elapsed from “go” The team says “stop” Any part of a goal touches the floor outside of the playing field The team touches the robot The robot is moved by wires connecting it to control box A team member steps on the playing field

28. Competition The robot may move the goals, but they must remain inside the playing field in any zone. If a scorable item is moved by the control wires, it will be out of play and may not be used to score points.

29. Competition Miscellaneous robot parts, or the entire robot, may end up in a goal without a penalty.

30. Competition At the end of competition, all controllers must be immediately set on the floor and the event supervisor will allow 10 seconds for the robot to “come to rest” with the power off to determine if any parts are touching the ground outside of the playing field.

31. Scoring At the end of competition, points will be awarded based on the number and types of items that were moved into scoring areas.

32. Scoring If the robot (parts touching the ground) at the end of competition is completely in: Zone B – 5 points Zone C – 10 points Zone D or the Goal(s) – 20 points

33. Scoring If a portion of the robot is left in another zone, the score received for the robot will be the lesser of the scores for each zone.

34. Scoring A scorable item that touches the floor outside of the playing field at any time, even if it is under the control of the robot, is out of play and may not be used to attain points. The robot or any scorable item on the line or straddling 2 zones will receive the lesser score.

35. Scoring If any part of a goal touches the floor outside of the playing field, the scorable items within that goal will have no point value.

36. Scoring A scorable item is considered in a goal if a part of the item is within the goal and the item is only in contact with the goal or other items contained therein.

37. Scoring Teams will receive the following points for each item moved into the following areas: Each item may be awarded points for only one of the designated areas.

38. Scoring Points in Points in Points in Points in Item Quantity Zone CZone D Small Goal Large Goal Golf balls 4 5 10 5 20 C-cells 4 6 12 6 24 Yellow Legos 2 8 8 24 8 Blue Legos 2 8 8 8 24 Coins $0.40 total value value 3x value value in cents in cents in cents in cents

39. Scoring Maximum score is 412 The team with most points will win. Tie breakers: 1 st - Shortest time 2 nd - Lightest mass of robot and batteries

40. Scoring Robots failing to meet any of the specifications under “Materials” will be allowed to compete but will be ranked below those that meet specifications. Robots violating FCC regulations will not be allowed to compete and will receive participation point(s) only.
