Building a robotic hand capable of human-like dexterity used to require a budget that would make most university departments wince. TetherIA just dropped that price tag to $314.
The company launched the Aero Hand Open, a tendon-driven robotic hand designed specifically for embodied AI research and dexterous manipulation experiments. It’s fully open-source, fully 3D-printed, and weighs just 389 grams.
What’s actually in the box
The Aero Hand Open packs 16 joints delivering 7 active degrees of freedom. Five fingers and a thumb, with the thumb offering 3 degrees of freedom on its own, give the hand enough articulation to handle grasping and manipulation tasks.
The entire construction is modular. Every structural component can be produced on a standard 3D printer, which means replacement parts are a filament spool away rather than a purchase order away.
