Endoskeleton refers to a type of skeletal structure that have developed inside of a living creature's anatomy.

For tagging purposes, endoskeleton here refers to a robot's internal framework and the machinery attached to it, specifically when its visibly depicted on the post. Likely due to circumstances such as the absence of an exterior covering, having a translucent body, or an internal / x-ray perspective.

This tag is often misused with animatronic. If you're referring to that species of robot then use that tag instead.
