This paper describes a patient-robot and a humanoid robot that physically grows like human.
　Recently, the number of people of dentists increases every year. However, the lack of skill of graduates of schools of dentistry is obvious. The problem seems to lie in the fact that the dentists have no sufficient experience of treating human patients. The present study was made in order to develop a patient-robot for use in an actual clinical training. The patient has the possibility of making an unexpected motion while treating. This motion often surprises the dentist. Therefore, it is important to develop a whole body patient-robot.
　Human grows mentally and physically. This research, aims at reproducing the human physical growth and walking sequence by using physical models. It introduces a growth process of body parameter by physical models and the human walking motion. Growth processes of these models are reproduced using from the average measurement of multiple human data.
