Abstract—At the Fukushima Daiichi Nuclear Power Station, various robots are currently being developed and operated for decommissioning [1]. However, as the number of robot arms and cameras increases, the number of displays and buttons increases, and the operation tends to be complicated. The maneuverability is reduced because the operator must maneuver the robot while viewing many displays and buttons. Therefore, in this research, as a system to support the vision of the pilot by utilizing the MR device, we developed a system that can project the image obtained by the web camera using the MR device and check both the image and the controller. We confirmed that low-latency, smooth images can be transferred, and we confirmed that there was no problem with maneuvering even if actually operated on a robot. As a result, a simple remote control system using a MR device and a web camera could be realized, and the basis of an operation system using a MR device in the future could be formed. At the beginning of this paper, we will explain about MR device and in the middle, we will explain about the development environment and the prototype system, and finally an application example and evaluation method.
