| Still an interesting thought experiment!

| https://en.wikipedia.org/wiki/Xenobot
|
| Xenobots built to date have been less than 1 millimeter (0.04
| inches) wide and composed of just two things: skin cells and
| heart muscle cells, both of which are derived from stem cells
| harvested from early (blastula stage) frog embryos.[7] The skin
| cells provide rigid support and the heart cells act as small
| motors, contracting and expanding in volume to propel the
| xenobot forward. The shape of a xenobot's body, and its
| distribution of skin and heart cells, are automatically
| designed in simulation to perform a specific task, using a
| process of trial and error (an evolutionary algorithm).
| 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.[2]
|
| Other kinds of motors and sensors have been incorporated into
| xenobots. Instead of heart muscle, xenobots can grow patches of
| cilia and use them as small oars for swimming.[8] However,
| cilia-driven xenobot locomotion is currently less controllable
| than cardiac-driven xenobot locomotion.[9] An RNA molecule can
| also be introduced to xenobots to give them molecular memory:
| if exposed to specific kind of light during behavior, they will
| glow a prespecified color when viewed under a fluorescence
| microscope.[9]
|
| Xenobots can also self-replicate. Xenobots can gather loose
| cells in their environment, forming them into new xenobots with
| the same capability.[10][11][12]

|
| Also about self replicating, does this mean reproduction? Are

| filoleg wrote:
| Looking at the wikipedia page, I think they were built irl.

| computer" to their "created in real life" analogs.
|
| That's just what I got out of reading the page though, so I
| would be glad if someone with more subject knowledge could
| either confirm or deny the correctness of my understanding
