9-in-1 Science Kit

Build. Experiment. Transform. Learn. Repeat.

The Weeemake 9-in-1 Science Kit is not just a toy its a complete mechanical engineering playground. With nine fully buildable STEAM mechanisms, kids and teens get to uncover the secrets behind every machine they see in the real world — from engines and linkages to musical robots and motion systems.

If you want a kit that teaches real engineering, not gimmicks  this is it.

The 9 Official Builds You Can Create

Each project focuses on a real mechanical principle used in robotics, automation, vehicles, tools, and machinery:

1. Ultrasonic Guitar

Turn sound waves into interactive play — explore sensors, frequency, and user input.

2. Ultrasonic Radar

Build a working scanning radar and learn how sonar-based distance detection works.

3. Generator Mechanism

Discover energy conversion by generating power with mechanical motion.

4. Meshing Belt Driving Mechanism

See how belts and pulleys transfer rotational energy in robots and machines.

5. Slider-Crank Mechanism

The same principle behind engines and reciprocating machines — a real mechanical classic.

6. Crank-Rocker Mechanism

Learn how rotational motion becomes rocking oscillation. Used everywhere from tools to robotics grippers.

7. Double Rocker Mechanism

A dual-arm motion system that demonstrates linkages, stability, and coordinated movement.

8. Oscillating & Reciprocating Mechanism

Master the fundamentals behind pumps, presses, and automated linear motion systems.

9. Music Robot Mechanism

Assemble a rhythmic, sensor-driven robot that turns mechanical motion into music.
