World Robotic Olympiade 2013 Part 1: Materials

World Robotic Olympiade 2013 Part 1: Materials
·         The controller, motors and sensors used to assemble robots must be from LEGO® MINDSTORMS sets and HiTechnic (HiTechnic NXT IRSeeker V2 sensor and HiTechnic NXT Compass sensor). Other LEGO branded elements may be used to construct the remaining parts of the robot.
·         Control programs must be ROBOLAB or LEGO® MINDSTORMS™ NXT software.
·         WRO recommends use of Education versions of LEGO MINDSTORMS due to extended service available from LEGO Education distributors.

Playing Field

1.1 Floor
  • 1.1.1. The playing field for the GEN II and Lightweight League is 122 cm by 183 cm. The field has white borders 30cm wide. Download Diagram from http://www.robocupjunior.org.au/
  • 1.1.2. The floor of the playing field is covered with a printed vinyl, roll resistant mat available from Tuzzles (www.tuzzles.com)
  • 1.1.3. The central playing area should be placed so that it is flat and level. All white borders, including the ends of the field are flat and inclined by raising the outside of the border by 1cm. (the incline should allow the ball to roll from the top of the side incline to the neutral area line)
  • 1.1.4. The field must be either placed on a carpet base. The recommended carpet is 3 mm thick outdoor carpet.
Visit http://www.robocupjunior.org.au/ for field construction hints for competition and the classroom.
  • 1.1.5. The field may be placed on a wooden or plastic table or on the floor.
Hint: It is recommended that teams design their robots to cope with slight imperfections up to 5 mm on the surface and the incline.
1.2. Walls
  • 1.2.1. Matte black walls are placed all around the field, including behind the goals.
  • 1.2.2. The walls are 8 cm high above the playing field.
  • 1.2.3. The walls can be constructed of any material as they are not essential to game play. Pre fabricated walls and goals can be obtained from Modern Teaching Aids http://www.teaching.com.au/lego_robocup.asp.
1.3. Goals
  • 1.3.1. The width of each goal is 45 cm.
  • 1.3.2. The back and sides of the goal interior are painted sky blue. The floor is white. The external sides of the goals are painted matte black.
  • 1.3.3. The depth of each goal is 7.4 cm.
Hint: Existing goals can easily be modified by placing 6mm plywood on the back wall.
  • 1.3.4. Each goal will have a black cross bar 14cm above the playing surface.
  • 1.3.5. The surface within the goal area is flat and level (horizontal).
  • 1.3.6. The side walls of the goals extend to the end wall to prevent ball from rolling behind the goals.
1.4. Neutral Zones
  • 1.4.1. There are two neutral zones, shown in white below, defined in the field.
  • 1.4.2. They are defined as the line between the corners of the penalty boxes, running along the field on the boundaries of the green colour zones.
1.5. Lighting and Magnetic Conditions 1.5.1. Teams must come prepared to calibrate their robots based on the lighting and magnetic conditions at the venue. Organizers will attempt to keep light levels as low as possible and locate soccer fields away from magnetic fields such as under floor wiring and metallic objects. However sometimes this cannot be avoided.
It is recommended that teams design their robots to cope with variations in lighting and magnetic conditions, as these vary from venue to venue

2.1. Specification
§         2.1.1. A well-balanced electronic ball diameter 7.4 cm shall be used.
§         2.1.2. The ball will be used in pulsed mode in all leagues. EK RoboSoccer RCJ-05 ball operated in MODE D (pulsed), Hitechnic Infrared Electronic Ball(IRB 1005) in MODE D (pulsed ).
