Dr. Ivo Robotnik

Dr. Ivo Robotnik (ドクター・ロボトニック, Dokutā Robotonikku) is a 70 year old retired roboticist with Asperger's Syndrome. Robotnik grew up in a time when Asperger's was poorly understood and lacked robust diagnostic criteria, as a result he was never formally diagnosed and is unaware that he has it, though he shows many symptoms. He wears soft robes made of fine fabric and has a custom-built belt containing fidget toys with which he stims while anxious or concentrating.

Robotnik spent his career trying to mimic the advanced systems of the sentient Robots. Though unsuccessful in his primary research goal, he made many contributions to robotics and was a celebrated mechatronic engineer. He now spends his leisure time working on his ideas for personal companion robots, such as robotic pets for elderly or disabled people, and synthetic lovers for the lonely. The prototypes use a form of sequential Monte Carlo filtering for localisation and mapping, and a combination of hidden Markov models and deep neural networks for human interactions. Unfortunately, Robotnik's workshop and tools are sometimes ransacked or vandalised by Sonic the Hedgehog, a local hoodlum, and his gang of miscreants. These ne'er-do-wells have coined the epithet "Eggman" for Robotnik, in reference to their regular eggings of his house.

Tails often visits Robotnik to wonder at his creations and hear stories of his past work. As Tails is an engineering prodigy, Robotnik considers him somewhat of a protege, destined to make great strides in electronics.
