The Grackle is a palm-sized autonomous repair drone, notable for its semi-aerodynamic beetle-like shell, triple-jointed repair limbs, and a high-frequency spot welder snout that hums faintly when active. Its casing is matte-gray with oil-slick undertones, often scuffed from constant hull traversal. Beneath its plated shell are pivoting magnetic limblets, allowing it to crawl over vertical or inverted surfaces with ease—ideal for internal tank walls, drone cradles, or vehicle exteriors in motion.
