More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age, enabling children to develop good personality and behavioral habits from the very beginning. Parent-child interactive handicrafts can enhance the quality of parent-child companionship and improve the parent-child relationship. The time we spend with our children, there are no mobile phones, ipads or TVS, only joy, interaction and communication. It can cultivate children's ability to solve problems by themselves. When encountering problems, children should first observe and experience them to solve them, because this is how parents and teachers solve problems during the process of doing handicrafts. It can develop children 's imagination. In children' s world, cars can fly in the sky and the sun can be green...... Playing with DIY handicrafts can cultivate children's hands-on ability.

Principle analysis
Knowledge Point 1: Centrifugal force: The motor at the bottom drives the eccentric wheel during rotation. The eccentric wheel moves in a circular motion around the motor's axis. The rotation of the eccentric wheel is far from the rotation center of the motor's axis, generating centrifugal force. The generated force is transmitted to the robot. The robot kept vibrating up and down. The wool on the wool strip is equivalent to many legs of a sweeping robot. When the wool strip keeps bending and stretching repeatedly during its movement, the robot can start to move.
