Enta's first foray into AI technology, v248 was the first version that did more than respond to simply yes/no answers or explode violently. It really only has the intelligence of a particularly smart dog, and has been trained to do many menial tasks for Enta such as picking up food, fetching needed materials (usually metal and corpses), acting as a personal tape recorder or protecting Enta to it's last breath.
The light head is often used to keep Enta's workshop illuminated at night, the microphone head for recording sensitive material, and the biting head just for when talking will not solve a problem.
