Double-arm shoulder joint mechanism of double-arm robot and both-legs hip joint mechanism of biped-walk robot

摘要

As a double-arm shoulder joint mechanism of a double-arm robot and a both-legs hip joint mechanism of a biped-walk robot, use is made of a double spherical joint having a construction such that joint rotation axes of 6 DOF are intersected at one point. As the double-arm shoulder joint mechanism of the double-arm robot, arms are connected respectively to a first spherical joint and a second spherical joint of the double spherical joint. As the both-legs hip joint mechanism of the biped-walk robot, legs are connected respectively to the first spherical joint and the second spherical joint of the double spherical joint.
