Flat-Frame Underwater ROV

A lightweight flat-frame underwater robot for inspection, research, rescue and demo use. A PETG frame holds a clear acrylic electronics chamber, multiple thrusters for omnidirectional movement and a single-axis waterproof gripper for simple grabbing and sampling. An operator drives it from a ground-station app with live video.
