Recently, Japan has witnessed a declining birth rate and an aging and declining population. Robots are expected to play an active role as a complement to the working population. In the Japanese robotic industrial market, the service field is expected to grow from 370 billion yen in 2015 to 4.9 trillion yen in 2035. Additionally, physical exercise is a preventive measure for the elderly. Therefore, in this study, we developed a system that enables humanoid robots to act as physical exercise instructors. An instructor performs physical exercise and acquires the joint position of a human from image data; moreover, the instructor makes the humanoid robot conduct the same movement through the Internet using the Robot Service Network Protocol, which is a common robot communication protocol. As an elderly human imitates the humanoid robot performing a particular movement, the instructor and elderly human can practice the physical exercise despite being physically apart. Additionally, the shortage of instructors can be addressed because one instructor can move several humanoid robots. In this experiment, two joints of the upper body of a humanoid robot were moved using a simulation from two-dimensional skeletal coordinates. Subsequently, three joints of the upper body of the actual humanoid robot were moved from three-dimensional skeletal coordinates. Consequently, we could send movement commands to humanoid robot NAO remotely. We confirmed that NAO moves in accordance with human movements in the simulation and actual robot. In future, we will also develop the lower body to increase the number of movements NAO can perform and a system where humanoid robots advise the elderly.
