Every year teams of intermediate and high school students from around the world compete in a competition like no other. They build robots that play against each other in a match of skill.
The Vex Robotics competitions are held year round, with the winners of tournaments getting to compete at the world championships each April
Among the teams involved is one from Wellington East Girls College - and they're keen to get more Wellington schools involved, and in particular, more girls involved in this field.
Issy Riddell-Garner is a Senior Leader in Wellington East Girl's College's VEX Robotics team, Double X.
She talks to Jesse Mulligan.
