  With the advances of artificial intelligence (AI) technology, many studies
and work have been carried out on how robots could replace human labor. In this
paper, we present a ROS based intelligence hotel robot, which simplifies the
check-in process. We use pioneer 3dx robot and considered different environment
settings. The robot combined with Hokuyo Lidar and Kinect Xbox camera, can plan
the routes accurately and reach rooms in different floors. In addition, we
added an intelligent voice system which provides an assistant for the
customers.
