Japan researchers have created a pair of robots- a girl and a dog - whose odour sensors can determine just how bad you smell.
CrazyLabo teamed up with Kitakyushu National College of Technology to build a robot that looks like a bulldog and another shaped like a woman's head, Discovery News reported.
The dog robot sniffs your feet, generating one of four responses depending on how bad the odour.
The robot loses consciousness, if it's particularly bad, but if your feet smell okay, the robot will nuzzle up to you.
The female head -named Kaori- which can translate as aroma, fragrance or simply smell, does something similar.
It produces an answer when you exhale onto its face, saying: "Good, like citrus," "Yuck! You have bad breath," "No way! I can't stand it!" and "Emergency taking place!"
Both robots use a commercial odour sensor that picks up on certain chemicals in exhaled breath or emitted by feet.
