Description
DIY Gear Reciprocating Car Building Kit – Wooden Automatic Reversing Gear Mechanism with Motor
Build an exciting mechanical vehicle with the DIY Gear Reciprocating Car STEM Kit! This educational DIY kit features a wooden frame, DC reduction motor, battery holder, gears and wheels that work together to demonstrate an interesting automatic reversing mechanism.
When powered on, the motor drives the gear system and moves the car forward. When the car reaches the edge of a flat surface, gravity shifts the movable gear mechanism, changing the gear combination and reversing the wheel rotation. The car then moves back and repeats the cycle.
This hands-on engineering project helps learners understand gear transmission, mechanical movement, energy conversion, gravity and friction through practical assembly and observation.
Ideal for students, young makers, STEM enthusiasts and DIY hobbyists, this kit combines mechanical learning with an engaging building experience.
