Here is some info about WALL-E.
WALL•E (short for Waste Allocation Load Lifter Earth-class), is the last robot left on Earth. He spends his days tidying up the planet, one pile of garbage at a time. During the 700 years he has existed, WALL•E has developed a personality, and he is more than a little lonely. Then he meets EVE, a sleek search robot sent to Earth on a scanning mission. WALL•E chases EVE across the galaxy and inadvertently embarks on a space journey that ultimately decides the fate of humankind.
