compact autonomous robot 3d model

A compact stealth autonomous wheeled robot with a low-profile rectangular chassis. Matte black and dark graphite materials, sharp angular hard-surface design, minimal yellow accent lines. Recessed ESP32-S3 camera hidden behind dark smoked acrylic, flush with the body, no visible face or eyes. Small flush-mounted LCD status screen on the upper front panel for diagnostics or simple video playback, non-expressive and industrial. Concealed pico projector module behind a narrow aperture on the front or side, subtle and secondary to the design. Industrial unmanned ground vehicle (UGV) aesthetic with layered panels, ventilation grills, exposed screws, and modular access hatches. Two partially enclosed side wheels and a hidden rear caster wheel. Realistic engineering proportions with internal space for batteries, motors, ESP32-S3 board, sensors, display, and wiring. High-detail 3D model, realistic scale, neutral background, grid floor.
