ROKR MI07 Mechanical Age DIY 3D Puzzle - Hammerhead Shark Add this Hammerhead Shark mechanical predator to your collection, featuring realistic motion, glowing lights, and armored styling. It's a DIY 3D puzzle kit that combines metal and plastic parts to create a sci-fi-engineered, dynamic piece. ROKR's Robobio Series reimagines one of the ocean's most iconic predators: the Hammerhead Shark. Blending biomimetic design with futuristic engineering, the mechanical model features a T-shaped sensor head, a laser-flashing central snout, side-mounted electroreceptor lights, pointed dorsal fins, and a 4-segment S-tail. This dynamic silhouette is enhanced with a silver-green metallic armor and mounted on a round base with gold stamping. Three lighting effects simulate biological rhythm, including a flicker awakening mode, slow pulse cruise mode, and rapid flash combat mode. At its core is a planetary gear-style 11,000 RPM reduction motor that creates smooth, consistent motion. Running on 3 AAA batteries(sold separately), this model delivers a striking fusion of engineering, motion, and sci-fi-inspired marine design.
