Anatomy Mechatronics

Anatomy Mechatronics is a project intended to make perfect models of individuals using technology.

Principles
Having branched off from cyborg research, Anatomy Mechatronics involves making a perfect model or doll of an individual such as a powerful esper using pure technology, with exact copies of their skeleton, muscles, organs, blood vessels and nerves. The only part which isn't perfectly replicated is the subject's brain. Though a collection of medical technology on paper, the machines extract energy in the exact same way as the organs they are based on, so the doll will get hungry and sleep at night in the same way as a person. Once complete, size doesn't matter and in the case of the doll based on Shokuhou Misaki, it was shrunk down for easier storage and transportation.

Background
The Anatomy Mechatronics project was one of several projects run in parallel, with the aim of preventing the loss of powerful espers, in particular the Level 5s. A key member of the project was an elderly woman who sought to preserve individuals who would eventually die and be lost, so at least something was left behind. During the course of the project, she created a model based on the 5th Level 5, Shokuhou Misaki. Foreseeing Academy City's destruction in the near-future and wishing to preserve it, the professor devised the Urban Processor as a final project to act as a backup for the city. As she was considered far too dangerous but too talented to be killed, she was imprisoned within a doll museum used as a secret prison.

Following her creator's imprisonment, the Anatomy Mechatronics Misaki sought out Shokuhou Misaki in order to have her rescue the professor. The two succeeded in reaching the professor, however after the old woman explained the project and its reasons, her subordinate shot Misaki. The professor and her subordinate then escaped so the professor could carry out her final project, abandoning her creation. However Misaki had used Mental Out on the subordinate beforehand and put paint-bullets in his gun instead.

After catching up with the professor, Misaki trapped her in an illusion and had her explain the purpose of the Urban Processor to her. Rejecting the professor's reasoning and knowing the dangers the Urban Processor could bring, Misaki chose to destroy it. With the professor having asked her to protect the Anatomy Mechatronics Misaki, she kept the doll with her afterwards.
