The KOOV Challenge is an international robot contest where children are challenged to design and collaborate with their peers using KOOV’s building blocks along with programming through code. In this contest, ranking high among the competitors is not the only goal. The KOOV Challenge is a contest where children meet worldwide contestants, challenge and enjoy together and go through the trial-and-error process where they are observing – thinking – talking – creating – failing - and thinking again. There is no "correct answer" in the KOOV Challenge. Any challenger with curiosity and enthusiasm toward science is welcome to join in.
