A Japanese robot hotel is canning more than half the robots working there. It turns out they aren't very good workers. The more than 240 robots frequently caused more problems than they solved at the hotel in Nagasaki. The hotel's manager and the company president have acknowledged problems that include check-in robots that need help, concierge robots that are clueless, luggage carriers that have trouble getting to rooms, and entertainment bots that break down. The name of the hotel is Henn-na, which means strange or weird in Japanese.
