5 DOF Robot Hand Five-Finger Bionic Palm, Servo-Controlled Left/Right Assembled Gripper for Arduino/ESP32, Raspberry Pi

Overview

The BinHex 5 DOF Robot Hand is a five-finger bionic palm driven by servo (steering gear) actuation. This assembled left/right bionic gripper is designed for programmable robot projects and is compatible with Arduino, ESP32, Raspberry Pi, and STM32 control platforms. It includes structural parts and steering gear; controller and power are not included.

Key Features

• Five-finger bionic palm driven by 5 steering gear servos; each finger can move independently and flexibly.
• Assembled, hand-built mechanism; structure may be updated occasionally, so minor differences from pictures may occur.
• Black acrylic construction.
• Working voltage: 5–6V DC; 7.4V sources must be stepped down.
• Mini metal-gear servos without overload protection—avoid locked-rotor/blocking.
• Wire mapping: Brown = negative, Red = positive, Orange = signal.
• Left or right orientation options (subject to selection).
• Suitable for school competitions, DIY robotics, and bionic manipulator research.

Specifications

What’s Included

• 1 x finished product palm
• 1 x servo

Note: The finished product of a single hand does not include the base. A control board and power supply are required and not included.

Installation and Safety Notes

• Do not exceed the operating range; avoid blocked rotation (locked-rotor) to protect the servo.
• Operate at 5–6V. If using a 7.4V battery, reduce voltage before powering the servos.
• Wire colors: Brown (negative), Red (positive), Orange (signal). Connect accordingly.
• Keep the assembly dry; do not expose to water.

Applications

• Programmable robot grippers and manipulators
• STEM education and school competitions
• Bionic hand research and DIY prototyping
