The ABU Asia-Pacific Robot Contest (ABU Robocon) is an Asian Oceanian College robot competition, founded in 2002 by Asia-Pacific Broadcasting Union. In the competition robots compete to complete a task within a set period of time. The contest aims to create friendship among young people with similar interests who will lead their countries in the 21st century, as well as help advance engineering and broadcasting technologies in the region. The event is broadcast in many countries through ABU member broadcasters. ABU Robocon extended the concept from NHK Robocon which started in 1991 and restricted to teams from Japan only. Each year the competition has different topics, but generally speaking two or more robots must be used to complete the tasks. One of the robots would be manual control while the others are automatic. The best robots usually weight more than 10 kg and span in one square meter area. To build the robots, contestants, who are restricted to be undergraduate students, must possess rich knowledge in programming, mechanical design and electronic circuit design. Each game is between two teams, often named red and blue. The playing field is symmetrical and robots from both teams start at the same condition (except for Robocon 2015 which employed a turn-based game based on badminton). A typical game (except for Robocon 2015) lasts for three minutes, but can end sooner if one team achieve a K.O victory which immediately finishes the game. In case that no teams achieve the K.O condition, the team get higher score after three minutes will be declared winner. Earlier editions of Robocon tend to emphasize the competitiveness of the game, in which winners achieve their win by employing strategic approaches to deploy their robots as well as preventing their opponent from reaching the goal. For example, this strategy was notable in Vietnam's win in Robocon 2004 and 2006, and China's win in Robocon 2008. To mitigate the problems, later editions reduce the combat nature and put more emphasis on technology, designing and making robot perform complicated maneuvers, which require teams to be more creative on designing robots.
