AMEE

AMEE, from the movie Red Planet, definitely doesn't deserve to go down in robot history as a short-lived villain. I would love to see her again, in another movie, in a bigger , I daresay, more suitable role, and maybe she can walk with heroes this time around.
AMEE - Red Planet
Her name is short for Autonomous Mapping Evaluation and Evasion. She is multi-task robot borrowed from the Marines to assist the Mars lending crew as their navigator while they try to figure out what went wrong with terraforming project. She is powered by "nuclear power cell the size of a beer can" which "runs her for eight months" as Gallager explains in the movie.
