Charmin's pooptime robot pal will bring a new toilet paper roll when you need it most and perhaps more important The Rollbot was accompanied on stage at the show by SmellSense, a sensor that will let you know before you enter a bathroom whether you are likely to gag or keel over from asphyxiation due to the activities of the previous occupant. SmellSense will give you a "no" or a "good to go" based on how much carbon dioxide or hydrogen sulfide it detects in the air.
The problem with such advancements is the deniers are thinking even if the problem is man made they'll expect engineers to solve the problem. If they can monitor greenhouse gasses in the bathroom surely they can scale up to eliminate them.
