Robot can substitute human in all video scene or image that need a model.

Observer or viewers can not make difference.
And we don't need any interaction between customer (viewer) and the image (video). We just pass a message or information.

We can use them when we don't need interaction between operator and audience, or don't need operator own opinion or judgement.

Some application :
Speaker in TV News
Mannequin model in fashion parade
Robot girl in public advertising image
Stuntman in movie
