service robot 3d model

Prompt: A service delivery robot with a friendly, cute appearance, standing upright. The head is a white, dome-shaped enclosure with a prominent black screen. On the screen is a blue digital cartoon smiley face with large eyes and a simple mouth, identical to the face in image_3.png. The robot's body is a segmented, white cylindrical structure with distinct horizontal lines. Its arms are articulated and bent in an "L" shape, holding and forming a flat metal tray positioned at chest level for carrying items. On the tray are two small beverage cans and a plate with food. The robot has a wider, stable base with four visible omnidirectional caster wheels (all-direction wheels) beneath it. The robot stands inside a simulation room with blue walls and a grey grid floor, similar to image_2.png. The floor around the robot is clear of any markings, and other human figures, tables, and props from image_2.png are visible in the background, out of focus.
