A thousand years into post-apocalyptic Earth, many forms of life have gone extinct, including humans. An alien robot series, called Minilens, is cleaning up the Earth and collecting the surviving flora for research purposes. The robots' duty is to destroy all radioactive barrels and to collect all flora. Aliens forgot that Earth has gravity, therefore Minilens can't jump.
