未來派機械哨兵於岩石海岸

A hyper-detailed CGI render of a futuristic humanoid robot with a sleek cylindrical form and glossy reflective surface. Its white head features a large circular opening atop and a central cavity. The body rests on multiple articulated legs extending from its base, interconnected by bundles of wires and cables — a central hub visible beneath. Behind it: a vast open sea with gentle waves lapping a barren shore. The sky is clear, scattered with soft clouds; on the horizon, towering white cliffs, eroded and ancient, suggest extreme remoteness. The ground is rocky and desolate, strewn with jagged fragments. The mood is profound isolation and quiet exploration — a lone machine standing sentinel at the edge of the known world. Rendered with cinematic precision: light glints off its shell
