The DOT-7 drones appear in the early seasons of DISCO in the mid 23rd century. I know, modern show serving as a prequel to TOS puts things out of whack. However, they are canon.

An autonomous drone would be too close to a “pre-warp” species, so the Federation is forbidden from interacting/using drones.
