Development of Tour-Guide and Co-Experience Robot System at a Theme Park using 5th Generation Mobile Communication System

3D jobs (dangerous, dirty, demanding) are expected to be replaced by autonomous robots. At a theme park, surveillance, cleaning, and guiding tasks can be regarded as 3D jobs. This paper aims to develop an autonomous tour guide robot system and co-experience system at a large theme park. One of the characteristics of the tour guide robot we developed is the use of QZSS (quasi-zenith satellite system) and CLAS (centimeter-level augmentation service), which realizes the centimeter-level positioning for autonomous service robots. On the other hand, co-experience realizes the sharing of experience through the robot utilizing the 5th generation mobile communication system. Experimental results at the theme park showed that the tour-guide experiment was successfully carried out and the co-experience system can provide sharing of the experience of the robot to the user.
