The present invention discloses a moveable robot that includes a processing control system; a rotation mechanism, a projection system that can be titled by the rotation mechanism to a first position to project a first image on a horizontal surface outside the body of the moveable robot, wherein the projection system is configured to be titled by the rotation mechanism to a second position to project a second image on a wall surface, and an optical sensing system configured to detect the user's movement, location, facial expression or gesture over the first image. The processing control system can interpret user's inputs based on the user's movement, location, facial expression or gesture over the first image projected on the horizontal surface outside the body of the moveable robot. The processing control system can control one or more outputs of the moveable robot based on the interpreted user's inputs.
