Trick-or-treat is a must do activity for every kid (and some adults) on Halloween. But have you ever imagined the person answering the door is not a human, but a Superhero ROBOT?! We actually made this happened on Halloween by dressing up our robots as Superman and Batman to create an unforgettable experience for trick-or-treaters. When the group of kids from the tutoring center 2 doors down came by, they were pleasantly surprised and thrilled to see custom robots answering the door.
