In this letter, we introduced a novel 2-DOF robotic wrist with a hollow channel. The proposed wrist was developed by stacking two symmetric 5R spatial manipulators using a reverse motion transmission mechanism. As a result, the proposed wrist mechanism has not only a wide workspace, but also a huge
A spherical two-degree-of- freedom wrist adapting the structure of the spatial parallelogram is proposed. A U type extended link out of three UU type limbs of the spatial parallelogram is selected as an output link. As a result, the wrist can be interpreted as being formed by combination of a U type…
This paper presents a new antagonistic tendon-driven joint (TDJ) which has an advantage of enhanced stiffness characteristics. Detailed mathematical analyses on the stiffness of typical TDJs are worked out to compare the stiffness among them. Prototypes of the proposed TDJ design are introduced in t…
