Xenobots, named after the clawed frog, are synthetic lifeforms that are designed by computers to perform some desired function and built by combining together different biological tissues.

Xenobots built to date have been less than 1 millimeter.

Xenobots have been designed to walk, swim, push pellets, carry payloads, and work together in a swarm to aggregate debris scattered along the surface of their dish into neat piles. They can survive for weeks without food and heal themselves after lacerations.

Xenobots can also self-replicate. Xenobots can gather loose cells in their environment, forming them into new xenobots with the same capability.
