“A small tracked survey rover built for navigating contaminated swamps. The body is constructed from yellow composite panels with dark green armored sections, featuring wide rubber tracks, sensor pods, and a front-mounted sampling arm. Ventilation grilles and sealed access hatches suggest protection against toxic gases. Biohazard symbols and serial numbers are printed along the chassis. The rover is perfectly centered against a pure white background, softly lit with neutral studio light, minimal shadow. Ultra-realistic 8K PBR materials with worn paint, rubber texture, and glass sensor reflections.”
