The index finger of human has already been modeled anatomically. This anatomical model has one problem in the tendon driven system. It is difficult for the index finger to produce both the torque in the negative direction at the PIPjoint and the torque in the positive direction at the MPjoint. The problem was solved using a new model of the index finger proposed in this study. In the new model, one extensor tendon was added at the MP joint. The computed simulation showed that the new model can produce any torque at three joints of the index finger. The new model is thus useful to investigate the control mechanism of the index finger.
