Nanobots

The Nanobots were a species of robots created by Professor Hubert J. Farnsworth that inhabited the Robot Planetoid during August of 3010. They were not visible to the naked eye, as they were extremely small. The Nanobots looked like little army tanks. The species was able to clean water by eating its toxic minerals. This caused them to evolve into the Trilobots.

Creation and Evolution
After digging in the Olduvai Gorge all day, the Professor discovered Homo Farnsworth, a missing link between apes and the he needed to prove Dr. Banjo wrong about. Hubert then went to the World Bone Premiere, so he could present his latest finding. But, instead of being logical, those ignorant museum members viewed the Farnsworth bone as proof to. Angry, the Professor wished he didn’t live on Earth, and moved to an asteroid in deep space that would become known as the Robot Planetoid.

The planetoid was completely lifeless. There was no food to eat, and no water to drink. Somehow, Hubert must have forseen this, as he took some robotic bugs he created to the asteroid, together with dehydrated pills. Hoping for a fresh source of water, Farnsworth later poured the Nanobots into a nearby pond. This caused them to eat toxic minerals, which made them evolve into a bigger creature that lived on land.

Trivia

 * The evolution of nanomachines may have been inspired by prior science fiction:
 * In the ' episode ' (1989), Wesley Crusher creates Nanobots called “nanites” which unexpectedly evolve to the point of sentience. Initially, an astrophysicist on board expresses skepticism concerning the possibility for machines to evolve.
 * In the 2002 novel  by, Nanobots evolve to other organisms in a short time. Whenever humans attempt to attack them, the robots have already evolved.
 * The pond where the nanobots first evolved is a reference to all earth life is believed to have arisen from.
