Robot Vision Rig Stares at Neon Calibration Cubes

Magenta and cyan neon light washes the matte faces of three geometric calibration cubes arranged in a tight row. A black robotic vision rig with a central lens rests directly opposite the targets, its casing reflecting the colored glow. Fine dust particles float suspended in narrow beams cutting through the dim university lab space. The cubes sit on a scratched metal workbench, their painted edges catching the overhead fixtures. Shadows stretch across the floor in the pre-dawn stillness of the Escuintla research facility. A tiny speck of dust rests on the rim of the central cube.
