Inavinate on Instagram: "NASA’s robotic “claw hand” is a specialized tool built to collect rocks and soil in places where gravity barely exists. Instead of relying on weight or friction, it uses motorized joints and reinforced metal fingers to grip samples with precise, controlled pressure. Guided by cameras and sensors, the arm can approach a rock with millimeter-level accuracy, securing it gently but firmly even in the vacuum of space. Many versions of this claw are more than simple grabbers.
