A novel open-source robotic hand is redefining the boundaries of what $300 can achieve in the realm of technology.
Dubbed the Aero Hand Open, this ingenious device can twist a bolt, elevate an iPhone, and effortlessly open a soda can.
Available either as a pre-assembled unit or as a kit for self-assembly, this innovation promises to potentially transform daily living.

Operational Mechanisms of the $300 Robotic Hand
The Aero Hand Open is the brainchild of TetherIA, a collective dedicated to the development of accessible, practical robotics.
Instead of embedding motors in every joint, the designers employ tendons—
Thin cables traverse each finger, facilitating simultaneous movement across multiple joints.
This engineering choice yields natural, flexible motions without the encumbrance of additional hardware. TetherIA
The hand encompasses 15 joints, with seven under direct user control, and weighs a mere 450 grams.
Because of its design, the fingers adapt seamlessly to the items they grasp—be it a smartphone, a can, or even a screw.
This self-adjusting grip represents a significant advancement in robotics, as many robotic hands struggle to hold objects securely without causing damage.
This hand achieves an optimal grip, maintaining firmness without excessive pressure.
The kit comprises all necessary components: 3D-print files, electronics, and open-source software.
For those who prefer not to engage in assembly, TetherIA also offers pre-built models that connect via USB-C. TetherIA
Upon connection, the hand activates immediately, responding promptly to commands.
Desire faster movement, a tighter grip, or steadier holding?
Simply modify a few lines of code.
The complete design, encompassing CAD files, circuit schematics, and control software, is hosted on GitHub, allowing for endless customization.
The Visionary Team Behind the Project
The name TetherIA encapsulates the ethos of this Californian startup remarkably well.
‘Tether’ refers to the cables facilitating movement, while ‘IA,’ which is AI reversed, embodies the notion that humans should steer artificial intelligence rather than becoming subservient to it.
The team’s intent in constructing the Aero Hand Open is to empower individuals—students, enthusiasts, or engineers—to delve into real robotics without the prerequisite of an elaborate laboratory.
The design may lack an array of sensors or extravagant materials, yet that is precisely the premise. TetherIA
It democratizes the field of robotics.
For approximately $314, one can transform a complicated research undertaking into a weekend project.
The future of robotics, once ensconced in obscurity, now resides within reach—on your desk and ready for action.
