This paper presents a vacuum-based wet adhesion system for wall climbing robots. This system allows an adherability and low friction performance when a suction cup adheres on rough surface such as concrete wall with small vacuum pump. It utilizes a seal action and lubrication action of a liquid to make the robot body adherable and slidable on the surface. The measurements of friction and seal performance...

The direction of a generated sound source can be estimated by humans using the time difference between both ears and the characteristics of the sound. However, it is very difficult to create an estimation system using a computer and two microphones. In this study, we propose a novel sound source direction estimation method, in which the feature difference of two recorded microphone signals is used...
