Yunji’s robots are already being used in more than 500 hotels in China to escort guests to their rooms, deliver room service and provide concierge-type assistance. The robots are also in operation in hotels in Japan, South Korea, Singapore, Thailand, Saudi Arabia and North America.

Ctrip says the collaboration is part of its artificial intelligence strategy, which kicked off in March 2017 with the launch of its “Easy Stay” smart hotel solution.
