It is unknown how TPOs came about, but they may have been robots built by the ancient Chozo that once inhabited SR388. Their simple design denotes the strong possibility that they are only maintenance drones for servicing Chozo-built structures and mechanisms, but they went rogue once the Chozo abandoned the planet. These mechanisms only fly in simple horizontal flight patterns, spinning their canister-like attachments for flight. These robots do not appear in Metroid: Samus Returns, the remake of Metroid II.
