uHand Hiwonder Robotic Bionic Hand Left & Right Pair Individually Moving Fingers

Product Description

The uHand robotic hands (left and right pair) are 1:1 scale bionic mechanical hands designed for robotics enthusiasts, educators, and developers. Each finger can move independently thanks to high-quality LFD-01 anti-blocking micro servos, ensuring smooth and reliable actuation. Built with a combination of acrylic and aluminum alloy brackets, the uHand is lightweight yet durable, making it ideal for DIY robot projects, research, or secondary development.

With multiple mounting holes, tie-rod structure design, and support for expansion, the uHand offers flexibility for integration into humanoid robots, manipulators, or experimental robotic platforms.

Key Features

• Full Left & Right Hand Set – Includes both robotic hands for complete applications.

• Individually Moving Fingers – Each finger controlled separately using LFD-01 anti-blocking servos.

• Durable Build – Acrylic and aluminum alloy bracket ensures lightweight yet robust performance.

• Tie-Rod Structure – Enhances joint angular velocity and expands range of motion.

• DIY Friendly – Multiple mounting holes allow easy secondary development and expansion.

• Servo Tester Compatible – Hands can be tested and controlled directly via servo testers or microcontrollers.
