Robot equipped with a detector for cigarette smoke (the kind used on aircraft and in other critical no-smoking zones), also capable of scaling moderate heights to access windows in a residence, and able to simply close them in response to incoming cigarette smoke. It would need to recognize, and interact with, the commonly installed varieties of window closing mechanisms, and have the gearing to apply the high forces required. It would sell well to parents of small children.
