การทดสอบหุ่นยนต์ตำรวจญี่ปุ่นใต้น้ำ

Cinematic vertical action still of a futuristic Japanese Metropolitan Police Department heavy-duty humanoid robot undergoing an underwater resistance test submerged just beneath the rippling surface of a [clear blue pool]. The robot is large, bulky, and tactical, constructed from angular [white and dark navy] armored plates with exposed black mechanical joints, hydraulic pistons, hoses, bolts, and sensor clusters. Its head consists of a rectangular multi-camera sensor bar with exactly four large circular glass lenses facing forward on a thick mechanical neck, plus a small vertical antenna mast on the right shoulder. Three dark armor panels feature crisp white text: "警視庁" above "MPD" on the central chest plate, the left shoulder shield, and the right shoulder shield. Translucent red police emergency light strips sit atop both shoulder shields. Dense air bubbles, splashing water droplets, and shimmering sun caustics ripple across the metal surfaces. Low-angle close-up front perspective, torso centered, sensor head in the upper third, arms extending outward. Bright aquatic sunlight, high contrast blue reflections, sparkling optical refractions, and a shallow depth-of-field pool background. Photorealistic sci-fi mecha concept art, crisp industrial textures, no people, no text other than "警視庁" and "MPD".
