New Japanese robot dog sniffs out smelly feet

Do your feet smell bad? If you don't dare to ask a friend, one Japanese start-up might have the answer with a new robot dog that will sniff your feet and give you a pitilessly honest verdict - even fainting if the stink is especially strong. Malodorous feet can be socially awkward in Japan where shoes are removed at the entrance to every home. Japanese start-up Next Technology has designed that can sniff out a person's feet and assess how strong the odor is. Hana-chan - a play on the Japanese word for'nose' and a common girl's nickname - is a helpful little robot mutt who will bark if she detects moderately whiffy toes, but will keel over if the pong is particularly pungent. The 15-centimeter (6-inch) dog, equipped with an odor detection sensor for a nose, also sprays air freshener to resolve the situation if the aroma is unbearable.
