ABSTRACT:
There is disclosed a multijoint in which the primary moment force caused by a combined gravity of the lower arm which is supported by an elbow joint portion for pivotting the upper and lower arm together and a distal mechanism fitted to the distal end of the lower arm, is minimized by imparting a force opposite the primary moment force thereby reducing the load of an electric motor for driving the elbow joint portion.
