This wearable mechanical hand kit allows users to assemble and operate a functional robotic hand using their own fingers. The system operates without motors or batteries, relying instead on air pressure and water hydraulics to power the movements. Hydraulic pistons enable the mechanical fingers to open, close, and grip objects with sufficient force for lifting. Each finger joint can be individually adjusted for precise positioning and movement control. The kit offers three configuration options: right hand, left hand, or claw-like setup, with adjustable sizing to accommodate most hand sizes. Through assembly and operation, users gain practical understanding of pneumatic and hydraulic systems, similar to those used in industrial robotics applications such as automotive manufacturing. This product was recognized as the 2021 STEAM Toy of the Year by The Toy Association.
