Abstract: An animatronic device includes a mechanical eyeball configured to rotate about a first rotational axis and a second rotational axis that intersect at a fixed center point. A controller is configured to generate eye movement instructions that cause the animatronic device to rotate the mechanical eyeball about at least one of the first rotational axis and the second rotational axis. The eye movement instructions are generated based on an eye tracking system used to track movement of an eye of a user. The controller maps the tracked eye movement to movement of the mechanical eyeball and generates eye movement instructions based on the mapping.

Abstract: A mechanical eyeball includes an outer housing shaped as an ocular surface configured to rotate about a first rotational axis and a second rotational axis that intersect at a fixed center point. The outer is housing is coupled to a mechanical assembly, and the mechanical assembly is contained within a volume associated with the mechanical eyeball. The mechanical assembly can include a stationary gear train and rotatable components that rotate relative to the gear train. The rotatable components are configured to cause rotation of the outer housing about one or more rotational axes. The volume may be substantially the same volume of a human eye. The mechanical assembly is coupled to one or more drivers configured to actuate rotation of the outer housing.
