Systematic analysis of Structural optimization design of post-disaster emergency rescue robot

Natural disasters do great to human life and post-disaster relief is significantly essential. Moreover, the post-disaster emergency rescue robots play an important role in searching, rescuing, transportation and detection. This paper wants to enhance the stiffness and force limit through the characteristics of the mortise and tenon structure by applying the mortise and tenon structure to the mechanical arm of the post-disaster emergency rescue robot. By analyzing the mechanism of robotic arm movement and mortise and tenon structure, it demonstrates the feasibility of the optimization of mortise and tenon structure applied on the mechanical arm. Through the application examples of mortise and tenon structure in related fields, the advantages and disadvantages of mortise and tenon structure in mechanical arm are demonstrated. The future prospect of mortise and tenon structure in mechanical arm is very optimistic, which can be used as an auxiliary connection mode in the design of mechanical arm, combined with traditional methods such as welding and bolt connection, to balance performance, cost and maintainability.
