TetherIA Unveils $314 Open-Source Robotic Hand for AI Labs

TetherIA has launched the Aero Hand Open, a tendon-driven robotic hand engineered for embodied AI research. The device is fully open-source and carries a price tag of $314.

Weighing only 389 grams, the hand features 16 joints with 7 active degrees of freedom. Its fully 3D-printed, modular design allows for cheap, on-demand replacement of parts without complex procurement processes.

Software compatibility includes ROS2, ESP32 microcontrollers, and a dedicated Python SDK. All design files and firmware are publicly available on GitHub.

The pricing fundamentally shifts research economics. Established dexterous hands often cost tens of thousands of dollars, limiting labs to single units and paralyzing experimentation due to high financial risk. TetherIA’s model enables research groups to run parallel experiments and iterate on hardware at scale.
