    We have developed an autonomous mobile robot which delivers medications in hospitals. We plan to expand its application more and we think we can apply this robot to a hotel and an airport where many people are walking around. There are two main differences between hospital environments and hotel or airport environments. One of them is floor condition and the other is narrow passenger corridor at a hotel and narrow moving space in an airport lounge. In order to apply this robot to these environments,the robot needs to have communication function with customers who use this robot. In this paper we describe demonstration contents and results which we carried out in 2017 January and we also show lessons learned which we got in this demonstration.

    JAMSTEC has operated autonomous underwater vehicles (AUVs) for scientific survey of seabed mineral resources. Conventionally, it is difficult for one support vessel to track plural AUVs in one operation. However, it takes a long time for one AUV to survey a large target area. To solve this problem JAMSTEC has developed an autonomous surface vehicle (ASV) with MHI. The vehicle instead of the support vessel, autonomously tracks AUV(s) and monitors its progress, enabling the simultaneous operation of multiple AUVs and thereby the survey of a larger target area within a given period of time. An important role of the ASV is to relay underwater communication and aerial communication because the underwater communication range is very small. ASV tracks AUV autonomously to keep the acoustic communication, and send AUV information to the support vessel by using radio waves.

    Recent progress in the Lab on Chip (LOC) technology has made it possible to analyze microscale objects in microfluidic devices under a microscopic environment. Vision-based microscopic analysis systems have a limitation in terms of their analysis range owing to the limited view area of the optical microscope used in photomicroscopy. Thus, expansion of the view area during microscopic observation is required. In this paper, we propose a view expansion system for photomicroscopy based on the viewpoint movement using a Galvano mirror. We develop a prototype of the proposed microscopic view expansion system that consists of a microscope, a Galvano mirror, and a vision system. Experiments are conducted to compare the view area of the proposed microscopic system and a normal microscopic system; the photographable range of the developed system is experimentally derived and evaluated. Finally, our system is demonstrated through panoramic image developing experiments for an expanded view area.
