Aero Hand Open

Model: Aero Hand Open

Aero Hand Open is TetherIA's low-cost open-source, five-finger tendon-driven dexterous hand. The official project repository identifies US$314 as the complete-kit price, not the price of one motor or a deposit. Seven active degrees of freedom control 16 joints (7 active, 9 passive) in a 389 g, 198 × 95 × 53.5 mm assembly. The 3D-printable platform uses a 6 V supply, USB communication and an ESP32-S3 controller, with open CAD/PCB/firmware, a Python SDK, ROS 2 packages, MuJoCo simulation and reinforcement-learning workflows.
