He might not be the beneficial addition to a home, but Larry the Robot was designed to do one thing really well: vomit. Larry is designed to keep vomiting until we learn how to deal with norovirus, the illness causing diarrhea and vomiting. (I shudder to think of an additional robot to address the the former symptom).
Larry is designed to reproduce the spray of common vomiting which can travel nearly 10 feet.
Clearly, he is not going to be a popular replacement for the cuisinart as a wedding gift. However, with 21 million cases are estimated in the U.S. annually, Larry could prove very popular if he helps develop a cure for norovirus.
