And once you're dead, your robot assailants will feed on the flesh

I'd call them zom-bots, but it appears these robots have more on their agenda than just eating your brains. Rather, that's just a means to an end:

The purpose of the Energetically Autonomous Tactical Robot (EATR)™ (patent pending) project is to develop and demonstrate an autonomous robotic platform able to perform long-range, long-endurance missions without the need for manual or conventional re-fueling, which would otherwise preclude the ability of the robot to perform such missions. The system obtains its energy by foraging – engaging in biologically-inspired, organism-like, energy-harvesting behavior which is the equivalent of eating. It can find, ingest, and extract energy from biomass in the environment (and other organically-based energy sources), as well as use conventional and alternative fuels (such as gasoline, heavy fuel, kerosene, diesel, propane, coal, cooking oil, and solar) when suitable.
