Meet Hana-chan aka the robot dog. Hana is here to help you gauge how smelly your feet are.

Hana has a sensor in its nose and is trained to smell your feet. If your feet smell nice, Hana will wag its tail. If your feet aren’t smelly so fresh, Hana will bark. And if your feet are as stinky as week-old macaroni salad that’s been laying out in the summer sun, Hana will literally keel over and “die”.

All this for just $9,280 ’cause can you really put a price on identifying how rancid your foot odor is?
