The AmazingHand is a fully open‑source robotic hand kit designed for creators, researchers, and robotics enthusiasts. Developed by Pollen Robotics and productized by WowRobo Robotics, it features a compact 3D‑printable design, 8 degrees of freedom, and internally actuated fingers for natural, expressive motion. With its lightweight structure, flexible TPU shells, and accessible control interface, AmazingHand is ideal for humanoid robotics research, education, and DIY innovation.
Features
- Fully Open‑Source Design — All mechanical files, firmware, and control code are openly available for modification and customization.
- 8‑DOF Dexterous Hand — Four fingers, each with 2 degrees of freedom, enabling flexion/extension and adduction/abduction.
- Internal Actuation — Each finger is driven by two Feetech SCS0009 servos using a differential mechanism for smooth, natural motion.
- 3D‑Printable Construction — Rigid internal “bone” structure combined with soft TPU outer shells for safe and adaptive grasping.
- Lightweight & Compact — Approximately 400 g, suitable for humanoid arms, mobile robots, and research platforms.
- Flexible Wrist Interface — Originally designed for Reachy2 but easily adaptable to other robotic arms and platforms.
- Easy Control — Supports serial‑bus control via Python, Arduino, or embedded systems.
- Community‑Driven Development — Backed by the Pollen Robotics open‑source community with active updates and documentation.
