Since RoboCupJunior embraces teamwork and collaboration among team members, a team should have more than one member to form a RoboCupJunior team to participate in the International event.
A team member(s) and/or robot(s) cannot be shared between teams.
Maximum team size is 6 members for Rescue, Soccer and Cospace, and 8 members for Dance (for RoboCupJunior Hefei, 2015).
Minimum age is 10 (for RoboCupJunior Hefei, 2015). This means: all members of a primary team have to be between 10 to 14 year old; any member of a secondary team has to be between 15 to 19 year old. Age as on 1st July in the year of the competition.
Every team member need to carry out a technical role for the team (robot design and construction, sensors and actuators, programming, etc.), this should be identified at the registration. The actual categories will be announced before the registration opens. In addition, each member is expected to explain his/her technical role and should be able to answer any questions at the technical judging.
Robots are not allowed to use any kind of communication during game play unless the communication between two robots is via bluetooth class 2 or class 3 (range shorter than 20 meters) or via ZigBee. Teams are responsible for their communication. The availability of frequencies cannot be guaranteed.
