Mochoog Stem 4WD assembly kit is a four-wheel drive DIY climbing vehicle, which can help children learn the mechanical transmission structure of the vehicle model by using their own hands on their practice. Learn how electrical energy can be converted into mechanical Energy, and how to change the chassis height of the vehicle to come across obstacles.Learn how to improve The vehicle 's cross-country ability to come across obstacles through adjusting the combination of transmission crankshaft's dislocation variation. Through learning practice, the children can systematically master the principles of energy transformation and mechanical movement structure, so we can say that a small climbing vehicle can foster a future mechanical inventor. It can helps to develop the children's creativity and ability of using hands and brain. In the procedure of assembling, children will have a taste of joy and achievement by conquering challenges from time to time, which is beneficial for children's creativity cultivation and intelligence development. package size (L  x W  x h) : 11  x  6.7 x 2.2&Nbsp;(inches)  vehicle size (L  x W  x H): 8.3 x 4.3 x 4.1&Nbsp;(inches)
