Thames & Kosmos Mega Cyborg Hand – Wearable Hydraulic Hand STEM Kit

Overview

Explore hydraulics, pneumatics, and robotics with a GIANT, water-powered hand you can wear. With more than 200 plastic pieces and piston tubes filled with water, this kit turns simple finger movements into mechanical action. No motors or batteries are needed—just your grip and the power of fluid pressure. When you slip the assembled hand onto your own hand, you’ll see how each finger responds to your movements, offering a tangible sense of how fluid power can move a limb and handle objects with surprising steadiness.

Hands-on build and operation

As you assemble, you’ll witness how hydraulic pistons translate small finger motions into opening, closing, and gripping actions. Each joint can be fine-tuned to different angles, enabling precise control. The result is a wearable mechanism that can grip lightweight items, lift them, or hold them steady for careful manipulation—perfect for exploring the basics of force transmission without the distraction of electricity.

• Wearable, hand-operated hardware controlled by your own fingers.
• No motors or batteries—air pressure and water drive the motion.
• Hydraulic pistons enable fingers to open, close, and grip with adjustable joints for precision.
• Three configurations available: right hand, left hand, or claw-like grip.
• Designed to fit virtually any hand size through flexible assembly and configurations.

Learning via real-world connections

Inside the 40-page, full-color manual, you’ll find guided builds and clear explanations of pneumatic and hydraulic systems. The material connects hands-on activities to real-world automation, helping you understand how these power styles move components in industrial robots. Discover how actuation, force transmission, and control come together in applications that require careful grip or controlled motion, all without electricity.

• 40-page guide with diagrams, experiments, and kid-friendly explanations.
• Context about pneumatic and hydraulic systems used in modern automation.
• Encourages experimentation with different grip strengths, configurations, and object types.

This kit earned recognition as a STEAM Toy of the Year in 2021 from The Toy Association, underscoring its value as a hands-on learning tool that blends play with science. The Mega Cyborg Hand invites curiosity, supports practical understanding of mechanical systems, and sparks ideas for future robotics or automation projects.
