Description
The ROHand brings a human-like form and versatile grasping motions into a compact robotic device. Its five fingers move independently, letting the hand perform a variety of gestures — from pinching and grasping small objects to holding tools. The design maintains proportions close to a human hand, which makes ROHand suitable for robots intended to handle everyday objects or tools originally made for humans. Because of its active degrees of freedom, it adapts to many use cases, whether precise manipulation or general-purpose gripping.
