WRO 2013 - Junior High - Borobudur


    Borobudur, or Barabudur, is a 9th-century Mahayana Buddhist monument in Magelang, Central Java, Indonesia. The monument consists of six square platforms topped by three circular platforms, and is decorated with 2,672 relief panels and 504 Buddha statues. A main dome, located at the center of the top platform, is surrounded by 72 Buddha statues seated inside a perforated stupa. Built in the 9th century during the reign of the Sailendra Dynasty, the temple’s design in Gupta architecture reflects India's influence on the region, yet there are enough indigenous scenes and elements incorporated to make Borobudur uniquely Indonesian. The monument guides pilgrims through an extensive system of stairways and corridors with 1,460 narrative relief panels on the walls and the balustrades.

    Worldwide knowledge of its existence was sparked in 1814 by Sir Thomas Stamford Raffles, then the British ruler of Java, who was advised of its location by native Indonesians. Borobudur has since been preserved through several restorations. The largest restoration project was undertaken between 1975 and 1982 by the Indonesian government and UNESCO, following which the monument was listed as a UNESCO World Heritage Site. Borobudur is still used for pilgrimage; once a year Buddhists in Indonesia celebrate Vesak at the monument, and Borobudur is Indonesia's single most visited tourist attraction. (Wikipedia)

    Figure 1.Black and Grey Relic Statue.
    (Three LEGO bricks + one LEGO plate in height, 4×4 studs in size with a LEGO minifig on top)

  • Grey Relic statue represents statues that are in good conditions.
  • Black Relic Statue represents statues that are in bad condition, and need to be sent back for restoration.

  • Figure 2.Stupa.
    (Four LEGO bricks in height, 7×7 studs in size)

    A stupa (from Sanskrit: m., स्तूप, stūpa, Sinhalese: ස්ථූපය, Pāli: थुप "thūpa", literally meaning "heap") is a mound-like structure containing Buddhist relics, typically the remains of Buddha, used by Buddhists as a place of worship. After "stupa", "chorten" is the most commonly encountered English term. The term "reliquary" is sometimes used, after a Christian functional equivalent. Stupas are an ancient form of Mandala (Wikipedia).

    Challenge Overview

    The robot begins in the "Start" area. It will have to pass through the valley and enter the "Shrine" zone. It will then need to lift up all the stupas in the “Grey Square” and place it outside the relic statue. The robot will then need to check for the black relic statue, and bring it to the "Finish" area (red zone) passing through the stairs.

  • Multiple programs in the robot are allowed. For scoring round, the participants are only allowed to choose program and press the enter button to run it. Participants are not allowed to make any additional input or setting to the chosen program.
  • The maximum dimensions of the robot before it starts are 250 mm × 250 mm × 250 mm. After it starts, the dimensions of the robot are not restricted.
  • The robot begins in the Start area (green zone) and finishes in the Finish area (red zone).
  • The robot must start within the Start area. No part of the robot is allowed to exceed the Start area before it starts.

The robot is considered to have reach the Finish area completely if all parts of the robot that are in contact with the table are inside the Finish area.
  • Robot may detached or drop LEGO parts onto the track to assist in completing the mission objective. The main part of the robot (NXT, motor, sensors) will need to enter completely the “Finish Area” as described in point 5.
  • No part is in the "Finish" areaNot all parts are in the "Finish" area"Finish" completely
  • The stupas and the relic statues inside are placed on the 4 square areas surrounding the elevated square. Both stupa and relic statues are made of various LEGO parts (See Figure 1 and Figure 2).

    • Challenge time (2 minutes) has ended.
    • The robot has returned to the Finish area.
    • Participant call for "Stop" of the match.
    • Violation of the rules and regulations herein.


  • Score will only be calculated at the end of the challenge or when time stops.
