A company has invented a robot dog which faints when it detects smelly feet.
Robot dog detects smelly feet
Hana-chan is the creation of the National Institute of Technology Kitakyushu College, in Kyushu, who have been working on it for over two years.
The toy dog, which has been made by their sister company NextTechnology, has a special sensor inside its nose and even sprays air freshener to make the bad pong fresher.
NextTechnology's Kimika Tsuji explained how a father's idea came to life.
He said: ''He told us his daughter had said his feet were smelly.
''But he didn't want to know how bad the odour was because he would feel hurt. That's why we developed this cute robot.''
