About Chestnut Robotics
Chestnut Robotics, formerly known as TetherIA, develops dexterous robotic hands and the hardware and data systems used to train them. Its Aero Hand family combines tendon-driven actuation, tactile sensing and open mechanical and software interfaces for manipulation research and embodied-AI development.
The company also develops the Aero UMI data-collection exoskeleton and GAIN3D data engine, linking human demonstrations with robot-hand control and training data. Aero Hand Open is presented as an open-source research platform; production deployment, customer scale and foundation-model maturity remain company-specific claims.
