A little about this puzzle

At an on-land marine restoration training tank, a mecha grips an empty coral support frame and lowers it onto a platform in the clear water. Its anchored base remains on dry ground. A researcher controls the demonstration, and a student watches from behind the dry-side rail with a blueprint folder. The wet worktable holds a camera housing, coiled hose, tongs, and an empty cup. A low bench carries a towel and one complete pair of gloves; a soft wheel stop rests behind the nearer table wheel. Fresh watercolor washes and clean outlines distinguish the coastal view, tank, and tools. The support frame is an empty training model, without living coral.
