Recently, volcano activation is increasing. Accordingly, various disasters occur. Among them, a debris avalanche has heavy effect for people who are living around volcano. Therefore, the observation method to surveillant volcano surface is necessary. In this study, we focus on to surveillant amount of volcano ash using excavator. Light and small observation tool is better than heavy tool in case of volcano surface. Because of we would like to move the observation tool to upper position of volcano surface. If the observation tool is light and small, the autonomous carrier like multi copter can move it. Our group develops light small excavator by slider mechanism and rotary drilling.

In this paper, we present prototype robot to replicate features of dragonfly flight. We have observed and revealed characteristics of dragonfly flight in lifting, cruising, and hovering. With flapping fore and hind wings out of phase, we have achieved sustained flight with our dragonfly prototype. We present overview of observation, flapping mechanism, experimental setups, and experimental results.

Curling is one of the winter sports called chess on ice. Athletes are required high level skill and smart strategy. This paper deals with curling phenomenon of rotation stone on the ice.To Understand this phenomenon, polypropylene and Teflon sheet makes low friction environment, and curling stone experiment was carried out. Then curling stone phenomenon was reproduced on force plate instead of ice.

Lunar rovers are required to move on rough terrain such as in craters and rear cliffs where it is scientifically very important to explore. Wheel typed rovers are popular for planetary exploration missions. However, there is a problem that the wheel typed rovers have possibility of stack. Therefore, this paper investigates a mechanism of kinetic behavior between the wheels of the exploration rovers and soil. This study especially focuses on influence on mobility of lugs. The fin called lug needs for running on soften surface like soil. However, there are few studies about the effect of lugs. Therefore, in this study, running experiments on simulant are carried out to observe the traversability of the wheel with lugs using slip ratio and electrical current.
