Abstract

In the complex unstructured road, mobile robots' ability to resist overturning is crucial. In this paper, a tracked mobile robot with passive deformation is developed based on the request of unstructured environment to the robots' movement. The robot can improve stability and the ability to resist overturning by the deformation of passive adaptive mechanisms. A comprehensive judge was made on the tilting of the robot by a standard method of Normalized Dynamic Energy Stability Margin and stability index. The dynamic stability of the robot with road disturbance and inertia force was analyzed and simulated. Theoretical analysis and simulation research offer a reference for the application and design of the robot's control system.

被动自适应机器人侧翻稳定性仿真分析
在复杂的非结构化道路中,移动机器人的抗倾覆能力至关重要。本文根据非结构化环境对机器人运动的要求,研制了一种具有被动变形的履带式移动机器人。通过被动自适应机构的变形,提高了机器人的稳定性和抗倾覆能力。采用归一化动态能量稳定裕度和稳定指数的标准方法对机器人的倾度进行综合评判。分析和仿真了该机器人在道路扰动和惯性力作用下的动态稳定性。理论分析和仿真研究为机器人控制系统的应用和设计提供了参考。
