The Johnco Cybot: Hydraulic Cyborg Hand lets young engineers build and operate their own wearable robotic hand powered entirely by hydraulics - no batteries or electricity required. Once assembled, the cyborg hand mimics the movements of a real human hand using a series of fluid-powered pistons and levers. Each finger joint can be adjusted to create precise grip movements, from a closed fist to an open palm, making it a fascinating exploration of mechanical design and motion.

Designed for both right and left handed users, the thumb can be repositioned easily, while the adjustable structure ensures a comfortable fit for a wide range of hand sizes. Builders can experiment with different grip techniques to pick up objects of varying shapes and sizes - from bottles to balls and small parts. Lightweight yet sturdy, this innovative kit blends creativity with engineering skill, offering hours of hands-on discovery and fun for curious minds.
