Hana-chan — a play on hana (nose) and a common girl’s nickname — is a helpful little robot mutt that will bark if she detects moderately stinky toes, but will keel over if they are particularly pungent. The 15-cm robot, equipped with an odor detection sensor for a nose, also sprays air freshener to resolve the situation if the aroma is unbearable. Manufacturers Next Technology created the robot in response to a request from a man who was desperate to know if he had a problem.
