Mecha della polizia al Robot Expo di Tokyo

Photorealistic eye-level wide shot of a bustling outdoor technology exposition in Tokyo on a paved plaza beside a body of water. Three massive humanoid mecha robots tower over the crowd: the central and largest robot has an intricate black and white armored exoskeleton, shoulder-mounted flashing red emergency lights, a multi-lens sensor array for a head, and white text "警視庁 MPD" emblazoned on its chest armor; to its left stands a slightly smaller blue-and-white mecha, and to its right a red-and-black mecha. In the foreground, Japanese police officers in dark tactical uniforms with "警視庁 MPD" on their backs patrol among diverse civilian crowds taking photos with smartphones, alongside smaller quadruped patrol robots and service droids. Blue fabric banners reading "ROBOT EXPO TOKYO" hang from metal scaffolding towers. In the background, modern Tokyo skyscrapers stand beneath a clear, bright blue daylight sky.
