We've all been in this situation...you do your business in the bathroom, then discover there's no toilet paper left on the roll. Well Charmin has unveiled a new robot that will deliver you a fresh roll of TP when you need it, right to the potty! At the Consumer Electronics Show in Las Vegas, Charmin debuted their new "RollBot" that links up with your phone, so if you find yourself without enough paper you can have it deliver some to you. The robot is small enough to roll under the stall door, and even features the Charmin bear face. At the convention, Charmin also debuted "SmellSense," a sensor that will warn you if someone else has already polluted the bathroom before you enter.
