The EM-J2-1a is designed to handle basic tasks. They are ideally suited to performing simple manual task such as janitorial, landscaping, housekeeping and grounds keeping; just to name a few. They are capable of following simple and detailed instructions. They can also be taught slightly more complex skills such as cooking by downloading the skill set. Geboku means humble servant in Yamataian.
The Geboku has a human appearance, the usual two arms, and two legs. The toes are not separated, but the fingers are. The fingers do not have fingernails and while they have a textured surface it does not resemble fingerprints. The Geboku has synthetic hair typically straight and styled to the owner's preference.
The biggest thing that marks the Geboku is their rather rudimentary face. They can blink their eyes, and their mouth moves when they speak. Their eyebrows are painted rather than hair. They can arch their eyebrows slightly, they can give a grin or a frown with the mouth. The Geboku does not have a tongue nor does it use vocal cords. It uses a voice program with a speaker in the back of the mouth.
While the body can be made to appear male or female, its appearance is that of your basic child's doll.
