Snake like unit using flexible spines and redundant actuation

In this paper we present a robotic structure with flexible elements which can be utilized for the minimal invasive surgery or for research of the exploitation in the underwater Domain. This utilization in different domains can be guaranteed by the modular construction with redundant activity and by utilizing multiple vertebrate. The modular construction of the system can allow two acting modes, respective acting by wires with a flexible vertebrate column and the acting with flexible vertebrate column by pushing, respective drawing. We propose a comparison between the two acting modes by the point of view of the charging of radial dimensions and of the functional capacities in principal for the utilization in medicine. To point out the structural and the acting advantages of the robotic system we will use analyze with the finite elements in static and dynamic conditions.
