These robots can be the best thing, especially if one is headed to a meeting or a date, and is unsure about the extent of body odor.
They have built a robot in the shape of a bull dog and another which has a woman's head.
The dog robot is programmed to sniff the feet and can respond in one of four ways. The robot loses consciousness if the feet stink and if the odor is good, the robot actually comes close and nuzzles up. Both robots employ a commercial odor sensor which is sensitive to the presence of certain chemicals in exhaled breath or emitted by feet.
The female head robot is called "Kaori," and when the person exhales to its face, the response again can be one of four. If it is a fragrance , then she could respond with "Good, like citrus," and if it's a foul smell, depending upon the severity, the response could be "Yuck! You have bad breath," "No way! I can't stand it!" and "Emergency taking place!"
