Abstract(in English) | In order to clarify the control mechanism of jaw movements, we have been developing an autonomous jaw-robot with a life-like structure and occlusal-force sensors, which is driven by masseter and lateral pterygoid actuators, all materialized by a cable-tendon DC-servo motor. To control these, we introduced an impedance-control scheme and an adaptive control mechanism, enabling it to perform a life-like open-close movement with clenching. This control scheme, however, employs a complete position-control in the isotonic phase for any actuator, which is incomprehensible in actual muscles. To improve this, we varied the amount of cable-length feedback, according to differences in muscles and movement phases, so as to simulate the activity of the stretch reflex more accurately. This modification and the addition of bilateral digastric actuators enabled the robot to perform a more natural open-close movement. |
