About this product

Gaia Hand 20 is Stella-Robot's modular dexterous-hand platform for embodied AI development. The manufacturer's August 2025 launch description specifies 16 active and four passive degrees of freedom, a biomimetic thumb and replaceable joint modules built around in-house micro-actuators. The hand is listed at approximately 790 g, with support for Isaac Sim and MuJoCo workflows. Sensing varies by edition: the base model focuses on motion control, Pro adds three-dimensional fingertip force sensing, and Ultra adds full-palm tactile arrays. These editions should be distinguished when comparing capabilities.
