Aero Hand Open Smart Bionic Cable-Driven 16DoF Five-Finger Dexterous Hand (Left/Right Side) for TetherIA

1. Purchasers of this product need to possess certain mechanical operation and open-source development capabilities.

2. This is an open-source product. You can view detailed documentation and relevant tutorials on the GitHub platform and official website after purchase.

3. The hand assembly is manufactured via 3D printing. Minor burrs and layer ripples are normal phenomena and do not constitute quality defects.

This is a bionic dexterous hand specially designed for dexterous manipulation research, reinforcement learning (RL) and embodied intelligence. It breaks the high cost barrier of high-performance dexterous hands. With an overall weight under 400 grams and a fully open-source architecture, it simplifies and streamlines the verification of complex dexterous manipulation algorithms.

Aero Hand Open employs a tendon-driven actuation architecture in which each motor distributes force through low-friction cable pathways to multiple joints, delivering coordinated motion without increasing actuator count.

This shared tendon routing keeps the hand under < 400 grams, while the compliant cable runs absorb impact energy to cushion interactions with objects and users.
