The design of a spinal cord for the humanoid robot satisfies both criteria in providing offering a smooth human-like parallel means of bending forward and sideways.
This paper presents a prototype of 3 degrees-of-freedom articulated spine for the doll-shaped humanoid robot Robota. This work follows an approach that emphasizes the need for a high human-likeliness in both the external features of the robot and in the kinematics of its motions to enhance human-robot interactions. The design of a spinal cord for our humanoid robot satisfies both criteria in providing offering a smooth human-like parallel means of bending forward and sideways
