LMPA Epidural Continuum Robot: A New Type of Programmable Stiffness and Environment Interaction Design

With the continuous development of robotics, the adaptability and flexibility of robots in complex environments have become a research hotspot. In practical application, the robot needs to face the changeable terrain, load and dynamic interactive environment, which puts forward higher requirements for the physical performance of the robot. This paper presents a variable stiffness robot epidermis design scheme, aiming to realize the adaptive ability of the robot in different task scenarios through the stiffness regulation of the epidermis. This study first conducted an in-depth analysis of the mechanical properties, and properties of epidermis materials, and comprehensively considered the properties of materials. Based on this, a variable stiffness epidermis structure based on intelligent material is designed, which can dynamically adjust its stiffness according to the changes of the external environment, thus achieving a balance between softness and rigidity. To verify the feasibility of the design scheme, this study performed a systematic analysis of the performance of the epidermis structures under different loads by modeling simulations. The simulation results show that the epidermis structure can effectively adjust the stiffness under a variety of complex working conditions, showing good adaptability. The research results in this paper provide a new direction for the intelligent design of robot epidermis, with broad application prospects, and are expected to play an important role in the future of robot technology.
