Discover the power of hydraulics with this 106-piece educational robotic arm kit. With no batteries or motors, it uses water pressure for realistic force transmission and smooth movement. Two play modes — gripping objects (up to a span of 70 mm) and ring shooting — deliver hours of fun and learning.

The hydraulic robotic arm is an ideal kit for curious kids and adults who want to explore the principles of hydraulics, mechanics, and energy transfer using water. Without the need for batteries or glue, you can build a fully functional model that demonstrates how fluid pressure can drive motion.
The model offers two easy-to-control modes: precise gripping and lifting of light objects with a jaw span up to 70 mm, and a fun ring-shooting mode with a magazine for smooth experiments. Its ambidextrous design suits both right- and left-handed users.
Why choose this kit:
- Hands-on STEM learning: develop mechanical thinking, hand–eye coordination, and understanding of pressure and hydraulic principles.
- No electricity or glue: safe, eco-friendly, and reusable.
- A rewarding challenge: 2–3 hours build time, difficulty 4/5 for a satisfying creative experience.
