Unleash hands-on creativity and real engineering fun with the Pro’sKit Hydraulic Cyborg Hand GE-634 — a wearable DIY robotic hand kit that runs purely on hydraulic power. Designed as an exciting STEM assembly game for children, this kit lets kids build a realistic mechanical “cyborg” hand that can open and close its fingers without batteries, motors, or electricity.
With 200+ precision parts, young engineers can assemble a fully functional hydraulic arm that uses water-pressure mechanics to create smooth, forceful finger movement. Once built, the cyborg hand can grip and lift lightweight objects, making it not just a science toy, but a real working model of hydraulic engineering.
The GE-634 features three adjustable build configurations, so the hand can be customized to fit different sizes — perfect for kids, teens, and curious adults too. It’s ideal for science projects, classroom learning, hobby builders, and anyone who loves robotics, DIY kits, and mechanical toys.
Whether you're looking for an educational gift, a school STEM activity, or a cool build-and-play robot hand, the Pro’sKit Hydraulic Cyborg Hand delivers a unique blend of learning, creativity, and entertainment.
