For an evaluation of walking motions, a body acceleration is considered to be an important measure. The reason is that, if the walking motion is stable, the body acceleration usually shows almost periodic patterns, and if not, it does not. Therefore, it is thought that, for an evaluation of crutch walking motions, the crutch user's body acceleration would be required. That is, unstable crutch walks...
Up to now, several kinds of walk assisting devices have been developed, and these have been usually used by injured patients. Patients who have their leg injured often use crutches in order to reduce their weight to be borne with their injured leg, because crutches are regarded as familiar devices. However, some patients who were injured by sudden accidents don't know about proper methods to use the...
Magnetically levitated robots can move without lubrication, they generally have advantages to the use in the various special environments such as in a dust-free room, in a vacuum, in a flammable atmosphere, and in vivo. Meanwhile, they have a disadvantage of small working volume corresponding to the allowable air gap between the levitated object and the electromagnets. In some cases, to construct...
The authors have been developing a crutch walk training system. In this research, there are two fundamental schemes: one is measuring the motions of a patient and crutches, and the other is analyzing these motions. These schemes are expected to be utilized in practical rehabilitation works. In the proposed system, a gyroscope was embedded into a crutch, and the angular velocity of the crutch was measured...

Traditional craftsmanship should be handed on to the next generation. Introduction of mechatronics technologies has potential abilities for recording and replaying such craftsmanship. Up to now, there have been some trials to conserve the traditional craftsmanship. However, most of these trials have been aimed for only conservation. In this paper, the way of using brush in calligraphy is focused on...
