ABU Robot Contest 2004 Seoul

The aim of this robot contest is to make machines by hand from design to construction which
will be most suitable to compete in the below contest theme and rules.

Reunion of Separated Lovers, ‘Gyeonwoo and Jiknyeo’

The theme of this contest is based on a love story in Asian legend. A couple called ‘Gyeonwoo & Jiknyeo’ are forced to be apart from each other with the Milky Way between them due to their laziness. Magpies and crows which feel sorry for the couple fly up to the sky and build a bridge with their bodies to get the couple together. It is called ‘Ojak Bridge’ (Bridge of Crow and Magpie). The couple get together by crossing ‘Ojak Bridge’ once a year, on July 7th by lunar calendar. It always rains on this day and we say that it is the tears of joy from Gyeonwoo and Jiknyeo for their reunion.

The aim of this contest is to compete for accomplishing “Reunion” by completing the unfinished bridge and carrying Golden Gift by Automatic Machine from “Gyeonwoo Zone (Zone A)” to “Jiknyeo Zone (Zone B)”. The duration of each match is three minutes.
