Dynamic response characteristic analysis of quadruped unmanned platform

In order to explore the dynamic characteristics of a four-legged unmanned platform carrying weapons, the stability and response characteristics of the launching action of an unmanned combat platform composed of multi-degree of freedom robotic arms and four-legged robots were studied. Based on the advantages of four DOF manipulator and four-legged robot, virtual prototype of four-legged unmanned combat platform is established to increase the working space of unmanned combat robot. The characteristics of the four-legged unmanned combat platform were calculated by using the three-edge stability cone method and the response value simulation.The results show that the minimum stability angles are 0.89, 5.43 and 0.18. The disturbance response value of 0° direction is respectively decreased by 1.47% and 29.89% compared with 90° and 180°. The disturbance response value of high and low direction is increased by 14.29% and decreased by 34.64% compared with 90°. It can be seen that the stability angle coefficient is minimum value and the stability reach maximum value when the muzzle is backward.In the mean time, the disturbance response difference gets minimum value.
