EcoBot II

We know what you're thinking. A robot that totes around human sewage, digesting living beings for energy? What, you're not inexorably excited about this? The EcoBot II (ah, what a benign, nonthreatening name) is fed flies into 12 sewage-based bacterial fuel cells, which break them down, digest them, and use the electrons released as current. And we don't wanna hear no jibberjabber about how it's only a matter of time before these bots turn on their human masters, because if you're gonna go, what's so bad about being slowly digested in human feces by giant robot oppressors?
