This cool robotic kit has a new gear wheel feature that makes it possible to do transmissions from a wheel that rotates when a model is pushed forward and turned various different sized gear wheels. The movement is transmitted and ending in a function like the arms of the robot. In this way funny movements will appear and act when kids are playing with the robots and at the same time they will learn about simple technology. You can build 10 different funny robot models, all with their individual and entertaining movements. All the robots have their own character and will be illustrated in the complementary story book. The intuitive build in early learning in this kit makes it very attractive for parents to give to their kids.
