Recently, the number of disabled peoples is increasing resulting from traffic accidents and sports accidents. The aim of this study is to develop a powered orthoses to provide upper-limb motion aid for these disabled peoples. In the earlier stage, an upper-limb orthoses was developed as a prototype. In this prototype, the command input is based on the neck inclination. Such a method of command input is sometimes inconvenient for the disabled peaples. In this paper, a new orthoses is described, in which a voice recognition is introduced for the command input system to avoid the inconvenience. And also one board computer is introduced in order to realize the transportability of the orthoses system. In the system, whole control unit are installed on a wheelchair. These improvements produce the powerd orthoses, which can be controlled simply and precisely as well.
