The World Robot Olympiad has three competition categories: 

1. Regular Category

2. Open Category

3. WRO GEN II Football (Pilot)

A team may only participate in one category.

The 2011 World Robot Olympiad will have two special exhibition categories:

1. College & University - Open Theme Exhibition

2. Renewable Energies Green City Challenge and Exhibition

The World Robot Olympiad has introduced new and more flexible age group definitions. 

The age group definition for the Regular and Open categories was changed to allow a little more flexibility. For WRO GEN II Football there is only one age group.

1. Elementary (Primary) School Age: Date of birth falls on or after January 01, 1999 

2. Junior High (Middle) School Age: Date of birth falls in the period January 01, 1996 to December 31, 1998.

(If date of birth falls outside this range, it must not fall more than 6 months after this period)

3. High (Secondary) School Age: Date of birth falls in the period January 01, 1992 to December 31, 1995.

5. College & University Exhibition: Open to all post-secondary school students.

NOTE:

• Participants are not confined to school-going students. Anyone can participate in the corresponding age groups.  

• College and university students may participate if the individual students fit into the HS age group bracket! 

• College and university students older than HS age group may participate in “College & University Exhibition” if invited by the host country. 

The WRO is a team-based challenge. To participate in each category of competition, students must work in teams.

A team consists of one (1) coach and two (2) or three (3) team members (competitors).

One (1) coach and one (1) team member is not considered to be a team and cannot participate.

The minimum age of a coach (and assistant coaches) is age 20.

Coaches may work with more than one team; however each team needs to be assisted by a responsible adult. This person may be an assistant coach.

Coaches may offer students advice and guidance prior to the competition, however during the actual Olympiad competition, all work and preparation must be performed by the student members of the team.
