it's composed of extremely sensitive wiring, especially around his stomach area. the gray parts of his body are made of a soft silicone, while the blue parts are just metal. the silicone has touch receptors inside of it, so whenever he senses pain, pleasure, or any other intense emotion, the signals send it RIGHT to his CPU unit in his "brain" I.E the sentient AI program that gives him emotions and thoughts. Think of it as if chatgpt was fully sentient.
