Chinese Restauranteur Boasts 18 Robot Workers
A restaurant in Harbin, China staffs 18 robots; one to welcome customers as they arrive, others to cook the food, and more to deliver plates to tables. The owner says the robots, which cost between 200,000~300,000 yuan ($32,000~$48,000 USD), can display 10 different emotions and speak simple phrases.
The robot stops automatically if a customer gets in its way thanks to ultrasonic range sensors, and will sound an alarm if it needs to be repaired. And it knows to return to its power source when it gets low on juice (its batteries have a life of around 5 hours).
