In case you were wondering “Can you laser etch rocks?”
You totally can.
Robo-rock was etched in raster mode at 20% speed and 100% power on a 35 watt laser.
Unlike the last robo-pet I had (grass) this one should be substantially harder to kill.
Related ideas we’ve come up with include etching a bunch with electrical symbols and casting them like runes for circuits. Of course this led to a discussion on casting bones, and then etching them.
