基于足地作用的重载六足机器人脚力分配与优化研究

Six-leg mobile equipment can be applied to military, post disaster relief, construction in mountain region, planetary exploration, etc., because of its advantages such as well stability, and strong adaptability of rough terrain. The domestic designed six-leg robots in recent decades are almost principle prototype with light load and small dimension, which can rarely be used to practical application. This project will conduct the following studies: ① Clarify the mechanical mechanism of leg-soil interaction by various leg-soil interaction mechanical experiments, which can lay a foundation for the high adhesion foot design; ② Propose the approach of bionic design for leg foot simulation of legged robot based on anatomy research results to design bionic leg foot mechanism with high carrying capacity and great adhesion force; ③ Establish recursive dynamics model of six-leg robot based on leg-soil interaction mechanical model to realize mobile control of six-leg robot; ④ Establish leg force distribution strategy and optimization method for six-leg robot under stable walking, foot slip and disturbance instability. To achieve the goal of practical application of six-leg mobile robot in rough terrain with the realization of leg-soil interaction mechanical effect and interaction mechanism, the design of bionic leg foot mechanism with high carrying capacity and great adhesion and the establishment of leg force distribution strategy and optimization method.
