World Robot Olympiad organizes robotics competitions in three different competition categories
The Regular category was the first competition introduced by WRO. It is a challenge based competition in which teams will build robots that are designed to solve a given challenge set on a table.
Later, the Open Category competition was introduced. The Open category is a theme based competition in which teams use their creativity and problem solving skills in constructing smart robotic solutions that complement the theme of the competition. In 2011 the theme of the Open category was “Robots for Life Improvement”.
In 2010, WRO introduced WRO GEN II Football for the first time and it is now an official competition in WRO. Here teams of two robots play a game of football (soccer) on a playing field. WRO share the rules for WRO GEN II Football with Robocup Junior Australia.
