4M KidzLabs Hydraulic Robotic Arm














4M KidzLabs Hydraulic Robotic Arm

Runs on water — no batteries
Control the movements of the arm and gripper purely via hydraulics using syringes and tubing. A great demonstration of fluid power transmission in a real working model.

Learning through play: principles of hydraulics
Understand how pistons and fluid pressure turn small motion into big force. Ideal for curious builders and STEM fans.
Discover how hydraulics work in practice. From the set of parts you will assemble a functional robotic arm that you control with syringes and water. Every movement of the arm and gripper is smooth and precise, so you can easily pick up and transfer small objects—all without electronics.
The kit supports STEM learning, builds patience and technical thinking, and brings plenty of fun while experimenting. It is a great choice for children and budding mechanics enthusiasts who want to understand fluid power and the principles of pistons.
- Hydraulic drive — smooth, precise control with water.
