Practitioners of manual medicine frequently employ motion palpation as a diagnostic tool, despite conflicting evidence regarding its utility and reliability. The introduction of variou...

The snake-like robot is a limbless bionic widely used in unstructured environments to perform tasks with substantial functional flexibility and environmental adaptability complex environments. In this paper, the spiral climbing motion of on outer surface cylindrical object was studied based three-dimensional biological snake, we carried out analysis optimization motion-influencing factors. Firs...

one of the debates concerning concepts of “medial motion” and “traversal motion” is the question of which of these two concepts of motion corresponds to motion in the corporeal world. in the present article we intend to employ the language of mathematics to present a model for each of these two concepts to study the above mentioned problem. as a result, medial motion represents a covering funct...
