Pirate Cargo Drone
From Metroid Wiki
Pirate Cargo Drones are harmless, slow floating mechanisms designed by the Space Pirates with the simple task of transporting cargo short distances. These machines are found by Samus hovering around Landing Sites in Metroid Prime 3: Corruption's Space Pirate Homeworld. They are meant to carry substances too dangerous for Space Pirates to handle. One shot from any of Samus's weapons can destroy these simple enemies, since they are meant to carry cargo and are not built to take structural damage.
