TsingSens AmazingHand - 3D Printed The Open-Source DIY Robotic Hand Kit

Overview

TsingSens AmazingHand – 3D Printed Open-Source Robotic Hand Kit is a desktop-scale robotic hand based on the open-source Amazing Hand project from Pollen Robotics and released on GitHub. The kit combines a 3D-printed PLA “skeleton” with soft TPU “skin”, linkage-driven fingers and dual-motor parallel mechanisms to reproduce realistic flexion, extension, abduction and adduction of the fingers.

Designed for makers, educators and researchers, this open-source robotic hand kit is easy to program with Python on a PC or via Arduino/ESP32, making it ideal for AI experiments, gesture demos and low-load grasping tasks.

Key Features

• Fully Open-Source Design
  – Mechanical CAD, electronics and control code are available on GitHub, allowing you to study, modify and extend the robotic hand for your own projects.

• 3D-Printed, Modular Construction
  – PLA bone structure with TPU “skin” for a balance of stiffness and compliance; components are easy to re-print and replace.

• Realistic Finger Mechanics
  – Linkage-driven joints with a parallel mechanism and dual motors (Motor A & Motor B) deliver natural finger flexion/extension and finger spread (abduction/adduction), closely mimicking a human hand.

• Easy Control with Python or Arduino
  – Connect the control cable directly to a computer and drive the hand using Python through a serial (TTL) interface.
  – Alternatively, program an Arduino and copy the code to the onboard ESP32 microcontroller; supports both TTL serial control and PWM servo-style control (PWM mode for standard servos via Arduino + MCU).

• USB Power Input
  – Powered via a 5V/3A USB power adapter (charger not included), making it convenient to use on the desktop or in the lab.

• Ready-to-Use or DIY Kit
  – Assembled version: arrives pre-built and ready to run out of the box.
  – Kit version: requires self-assembly, perfect for teaching robotics, mechanisms and hands-on STEM learning. All versions include accessories, motors and microcontroller.
