Mark VI combat mechanical
From Tardis Wiki, the free Doctor Who reference
Mark VI combat mechanicals were robotic soldiers. The Fleet created 5,000 of them for their wars.
Functionality
They had active phlebotinum armour. The main armament was a plasma-beam rifle built into their right arm. Targeting was aided by a laser rangefinder.
They moved using military-grade tank tracks, could move stealthily or hover using an antigrav engine. They had sensitive audio-detection circuits.
History
The Thirteenth Doctor reprogrammed them, starting with one she named Bernard, effectively turning them in a peacekeeping force. (PROSE: The Secret in Vault 13 [+]Loading...["The Secret in Vault 13 (novel)"])
