Abstract :
This paper takes up the problem of redundant degrees of freedom and impedance adjustment, which is one of important subjects on motion control. First, the impedance adjustment mechanisms and dynamic characteristics for the muscular-skeletal and spinal reflection systems will be described by using a bilinear system. Then, the coordinated action of two hands will be taken up, and it will be shown that the impedance adjustment at the joint and muscular levels plays an important role in the manipulation of objects. Finally, we discuss the neuroscientific standpoints of the precise and flexible motor control mechanisms
