Abstract
Currently, the use of communication robots has been attracting attention within the declining birthrate and aging population. For example, efforts have made to improve cognitive function of the elderly. We tried to maintain motor function of the elderly using a small humanoid robot at Long-Term Care Health Facility for the elderly. Through this activity, we surveyed an opinion for the robot and the activity. Therefore, we report the result of it. In addition, we tried to monitor and evaluate movements of the elderly while they do physical exercises, using 3-D depth sensor. In particular, we calculated angle, angular velocity and angular acceleration of elbow and shoulder joint from coordinates of the joint.
