We’ve decide to break the one of the law from the “Three Law of Robotics” by Issac Asimov in our project, which the Three Laws of Robotics are 1. A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2. A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law. 3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. The RUDEbot is oppose to the first law listed above. The camera traces one audiences’ face one at a time, and the feedback to the ultra-sonic sensor determines the hitting action whenever the host enters the “private space” of RUDEbot, which is a pre-set distance in the program we made.
