In this paper, we propose a method for recognizing human actions and objects and translating them into natural language text. First, 3D environmental map is constructed by accumulating range maps captured from a 3D range sensor mounted on a mobile robot. Then, pose of a person in the scene is estimated by fitting articulated cylindrical model and also(More)
In general, it is possible to find certain behavioral patterns in human daily activity. Such patterns are called as daily behavioral patterns. The purpose of this research is to learn and recognize behavioral patterns. In the previous methods, it is difficult to recognize in detail how a person acts in a room because the methods recognize only a sequence of(More)
The aim of this paper was to produce a lead-free machinable brass dispersed with bismuth and graphite particles by powder metallurgy process. The effect of the machinable elements on the elongation and machinability of extruded materials was investigated. The Cu-40mass%Zn (Cu-40Zn) brass powder with 0 3:23mass% bismuth additions were produced by rapid(More)
We previously proposed a wearable robot arm named Assist Oriented Arm, that solved weight and safety problems of the existing wearable robot arms. The previous user interface of AOA was consisted of multi-button switches. However, the previous version did not satisfy the users due to its complexity of operations. To solve this problem, in this paper, we(More)
