A Japanese company, Next Technology, has created a robot dog that can tell you how bad your feet smell, by using a powerful sensor fixed in its nose. If you feet don’t have a bad smell. Hana-chan will happily wag its tail, if it's exposed to feet that are mildly smelly, it'll start to bark, and if they give off an extremely bad smell, it'll just fall over like the smell caused it to faint(昏倒).

Foot odor (脚臭) is a big deal in Japan, where it’s a custom for people to take off their shoes whenever they enter someone's home. In fact, exposing others to bodily odors can be considered annoyance in Japan. Some of the most brilliant minds in the country's tech industry have been trying to solve this problem. Last year, Thanko started selling axmpit (腋窝) fans designed to keep people's armpits nice and dry Now, we have Hana-chan.

The robot dog has a special sensor for a nose, and can tell you if your feet smell just by sniffing them for a few seconds. According to some media reports, Hana-chan can help solve the problem of extremely smelly feet by spraying them with air freshener, but it's unclear whether this feature comes built-in, or if you'll have to pay extra for it.

According to researchers at NextTechnology, the idea for Hana-chan was inspired by a person who desperately wanted some way to know if his feet smelled. "He told us his daughter had said his feet were smelly, " NextTechnology's Kimika Tsuji said. “But he didn't want to know how bad the odor was because he would feel hurt. That's why we developed this cute robot. "

You may be able to make Hana-chan faint with your smelly feet, but it can have the same effect on budget-conscious people. NextTechnology plans to start selling the feet-smelling robot dog for ￥100, 000 ($9, 280) next May.

Now more companies are experimenting with the concept of connected clothes. Among the pioneers is London based Cute Circuit, which has been creating fashionable smart clothing since 2004. The company’s latest innovation is the “Sound Shirt”, which allows deaf people to “feel” live music by transforming the tunes into touch sensations (感受) in real time.

The fashionable jacket uses software that changes the music into data and wirelessly sends it to the 16-micro motors fitted inside the clothing’s fabric (布料). The devices shake with the intensity (强度) of the music being played, allowing the wearer to feel each instrument individually. For example, violins can be felt on the arms, while the deeper, heavier bass notes can be felt close to the stomach. The series of touch like sensations across the wearer’s body enable him or her to feel the entire music, resulting in a musical experience.

To ensure the shirt is comfortable, the designers chose to leave out wires and instead wove conductive textiles (导电纺织品) into the garment’s fabric. Francesca Rosella, chief creative officer of Cute Circuit, explains, “There’re no wires inside, so we’re only using smart fabrics — we have a combination of micro-electronics and very thin and flexible and conductive fabrics. All these little electronic motors are connected with these conductive fabrics so that the garment is soft and stretchable.”

Cute Circuit, which has been testing the Sound Shirt for three years, expects to make it available to the general public shortly. Priced at $3,673, the smart jacket won’t be cheap. However, twin sisters Herman and Heredia Breanne, who lost their hearing at a young age, believe the hi-tech garment is a worthwhile investment, especially for deaf people with a passion for dancing. “It’s almost like feeling the depth of the music,” says Herman. “It just feels as though we can move along with it.”

Robots used to be found only in science fiction. In the 1960s, the animated space-age family the Jetsons had a robotic maid who could do household chores. In real life robots function in many manufacturing and household situations. In the filed of medicine, robot patients help train doctors and nurses by pretending they have a variety of health conditions. 【小题1】

The global pandemic and resulting economic crisis have created a lack of restaurant workers. Since restaurants don’t have enough workers, the remaining staff must work harder. Regardless, customers face longer wait times, fewer menu choices and higher prices. 【小题2】 These robots are not exactly modeled after Rosey, the Jetsons’ robotic household servant, but they are pretty clever (and very cute).

【小题3】 Many have a design that looks like a rolling cart. One model named Bella even has a cute cat-like face. Many are fairly short and shaped like R2D2 of Star Wars fame. They are designed to deliver dishes to regular customers in a restaurant. 【小题4】 They can not only deliver delicious food to performing repetitive tasks, however many there are. They can not only deliver delicious food to hungry customers, but also get back dirty dishes at the end of the meal.

【小题5】 Concerning the price, a server robot costs from a few thousand to several thousand dollars. Regarding safety, special sensors on the robots keep them from crashing into customers. Because there aren’t enough restaurant workers, filling positions with these robotic servers is a no-brainer. Don’t be surprised if you see one rolling up to your table soon.
