Thames & Kosmos Mega Cyborg Hand STEM Kit — Wearable Giant Hydraulic Robotic Hand, Adjustable Fit, 200+ Parts

Build a wearable giant hydraulic hand that mimics real finger motion using water-filled pistons—no batteries or motors required. The Thames & Kosmos Mega Cyborg Hand STEM Experiment Kit teaches hydraulics, pneumatics, and basic robotics by letting you construct a full-size mechanical hand you wear and operate with your own fingers. Using more than 200 plastic parts and piston tubes you fill with water, the model demonstrates how pressure and linkages convert movement into strong, repeatable grips. A full-color 40-page manual walks through assembly, experiments, and real-world engineering applications so learners can explore both construction and the science behind the mechanism.

How does the hydraulic system let the hand grip objects?

The kit uses water-filled piston tubes that transmit pressure to the finger linkages. When you bend the control fingers, fluid flows into the piston chambers and pulls the mechanical fingers closed, providing a firm, controllable grip without electronics.

• 200+ plastic components and piston tubes form the hydraulic network.
• Adjustable joints let each finger close to different angles for precision.
• Hydraulics amplify small control movements into stronger gripping force.

Can the cyborg hand fit different people and grip styles?

Yes—the design adapts to many hand sizes and three configurations: left hand, right hand, or a central-thumb claw setup. The strap and modular assembly let you shift the thumb position and resize the glove to fit children and adults for diverse experiments.

• Three configuration modes: right, left, and claw-like thumb placement.
• Adjustable strap and finger link lengths accommodate most hands.
• Quick part swaps allow reconfiguration without rebuilding from scratch.

What kinds of experiments and learning outcomes are included?

The illustrated manual offers step-by-step builds plus hands-on experiments that reveal principles of pressure, force, and mechanical advantage. Kids and hobbyists compare hydraulic and pneumatic behaviors, measure lifting ability, and test how finger-angle adjustments affect grip strength.

• Guided experiments exploring pressure, force, and fluid dynamics concepts.
• Comparisons of hydraulic versus pneumatic action and real-world examples.
• Open-ended challenges like lifting different objects to test performance.

Is any special equipment or power source required?

No electricity or motors are needed—the kit operates using air, water, and your own hand motions. All parts are included to assemble the glove; you only need a small amount of water to fill the pistons and common household items for some experiments.

• Operates without batteries or plugs—hydraulics and pneumatics power motion.
• Includes all plastic pieces, piston tubes, and a 40-page manual.
• Requires only water and a flat workspace to build and test.

Who is this for? The Thames & Kosmos Mega Cyborg Hand is built for curious learners, STEM classrooms, and hobbyists who enjoy hands-on engineering projects. It’s ideal for middle-schoolers through teens and adults interested in mechanics, robotics, or industrial systems, and for teachers seeking a tangible demo of hydraulics and pneumatics. Because the kit emphasizes exploration and reconfiguration, it also works well for makers and after-school programs that want a durable, repeatable model to compare designs and test hypotheses.
