After a long, tiring day in the big city, you may want to avoid human interaction where possible. If that is the case, the robot-staffed Henn na Hotel in Japan could be the perfect rest place for you. The hotel's staff of multilingual robots, from humanoid to dinosaur, are ready to greet you upon your arrival, assist you with check-in and checkout, while the robotic arm at the cloakroom will store your luggage. What's more, in this hotel there is no more worrying about misplacing your key card, as facial recognition technology is used to enter your room. Not to mention, the hotel uses state-of-the-art technologies, including smart art conditioning systems, which can draw heat from your body to cool you down, or keep heat from escaping your body when you feel cold.
