In femoral fracture reduction, it is required for the orthopedic surgeons to pull distal bone fragments with large traction force and return it in correct position referring 2D-CT imaging. Since these method had been burdened with them, it is effective to introduce robot assist. The robot had been developed, but the control method is not established yet because of lack of experiment data. The reason of lack of experiment data is we cannot carry out the experiment because the cadavers or animals are different from living body in muscle characteristic or anatomically. So the experimental model that simulated human femoral characteristic is needed. In this research, human muscles can be reproduced by using Mckibben type pneumatic rubber actuator (artificial muscle), and developed the model that simulated typical femur muscle with artificial muscle.
