Amazing Hand is a 3D-printed, open-source humanoid hand with 8 degrees of freedom and four fingers. Fully actuated internally, lightweight (400 g), and low-cost, it features flexible shells for natural movement. Perfect for research, education, and robotics, it combines dexterity, simplicity, and accessibility in one compact design.
- Open-Source Design The Amazing Hand is fully open-source, with all code and mechanical designs freely available. This allows easy customization and adaptation for a wide range of robotics projects.
- 8 Degrees of Freedom (DOF) It features eight degrees of freedom across four fingers, each with two articulated phalanxes. This enables versatile and natural hand movements.
- Compact and Lightweigh All actuators are housed inside the hand, eliminating external cables. At only 400 g, it is lightweight and easy to integrate into various applications.
- 3D-Printable and Cost-Effective The hand is fully 3D-printable and includes all modular components, makes it an affordable option for students, hobbyists, and researchers.
- Ideal for Research and Education Its open-source and accessible design makes it perfect for AI experiments and robotics learning. It is also suitable for data collection and algorithm validation.

AmazingHand is designed to work with its companion open-source software, providing powerful features for teleoperation, data collection, and AI learning:
Teleoperation
AmazingHand supports multiple advanced teleoperation methods:
- Strain Gauge Glove Control: Wear a custom glove for real-time, immersive, one-to-one control of the robotic hand.
- Hand Posture Estimation Control: Use a standard camera to capture your hand's posture and directly map its movements to the robotic hand without any wearable devices.
Data Collection
The platform facilitates data collection for robotics research and AI training:
- Joint Angle Recording: Log precise angle data from each servo in real-time.
- Visual Data Capture: Synchronize and capture video feeds from a camera during operation.
- Task Demonstration Recording: Easily record complete task demonstrations for training AI models, such as in imitation learning.
Sensor Streaming
The system can stream servo data (e.g., position, load, temperature) to a host computer for:
- More intensive processing
- Data visualization
- System monitoring
