The Henn-na Hotel in Japan found that robots annoyed the guests and would often break down.

Guests complained their robot room assistants thought snoring were commands and would wake then up repeatedly during the night. Meanwhile the robot at the front desk could not answer basic questions. And human staff ended up working overtime to repair robots that stopped working.

One staff member said, “It’s easier now that we’re not being frequently called by guests to help with problems with the robots.”
