Wooden construction set "Tank", educational model

Assembled wooden educational STEM constructor "Tank". The assembled toy moves forward, demonstrating engineering principles applied in the real world. The constructor helps children get acquainted with the basics of engineering, mechanics and electricity in the simplest way.
Features:
A builder, toy and educational tool all in one, this hands-on educational toy allows children to assemble their own working tank while understanding the principles of mechanics, motion and electricity.
During assembly, the child develops fine motor skills and accuracy, and the interactive learning method encourages creativity, problem solving, and interest in how things work.
Made of high-quality, non-toxic wood. The wooden parts are smooth and durable, and can be assembled without glue. Once assembled, the child can color, decorate, and give it a unique look.
Easy assembly: simple and clear instructions allow children to assemble the toy with minimal adult supervision, making the set suitable for both independent work and activities with parents.
STEM (Science + Technology + Engineering + Mathematics) are educational methods that integrate science, technology, engineering, and mathematics into a coherent learning model to prepare the younger generation for a world of rapidly evolving technologies.
This is a great choice for a gift, as well as for schools and educational institutions where simple, reliable and clearly functioning educational models are needed.
Operating principle:
The model has an electric motor (powered by batteries) that transmits rotational motion to the wheels, so the assembled tank can drive itself.
Creating a circuit: By connecting the battery holder and the motor, the child learns what a closed electrical circuit is.
Belt drive: A child sees how a motor turns only one axle, while a tight rubber band makes the other wheels turn. This is a simple example of how motion is transmitted from point A to point B.
Frictional force: The rubber fits tightly against the groove of the plastic wheel. It is the static friction that prevents the rubber from sliding on the wheel surface.
Educational value: The child is introduced to electrical circuits and mechanical engineering.
Purpose: for home learning, classroom learning, project activities.
