Most of these robots don't use micro controllers, they use the inverters in the Ic's as artificial neurons. So there's no programming. Also its cheap
. You can have a 4 motor walker with legs made out of pipe cleaners and it would teach itself to walk
.Most of the designs are based on robots from 20years ago, With the advent of microcontrollers this type of robotics didn't really get its chance. So its something id like to see popular again.
