摘要四足机器人是目前研究最多且能实现最多功能的机器人，机器人领域一般按足数量，分为二足、四足、六足、八足…机器人，四足机器人是一个复杂的耦合运动系统，它相对更多足式机器人结构相对简单些，一般机器人的功能也能够实现，比如跨越障碍，上下台阶，在不平整的路面运动，它不用于传统的履带式或者轮式机器人，它腿部的动力学模型具有明显的非线性和复杂性，建模需要考虑的因素也是多得多，所以本文将完成四足机器人的动力学建模及后期仿真。47537

Title    4 foot bionic robot dynamic model and simulation analysis                 

Abstract

Quadruped robot dynamics model of the problem is to realize high precision control and the foundation of mechanical design. But the quadruped robot is active mechanism, Degrees of freedom of motion mechanism, And every joint can drive alone. Control theory point of view, It is a complex dynamic coupling complex system. The dynamic mathematical model has significant nonlinear and complexity. Compared with traditional wheel, crawler robot, Environment of the quadruped robot has a strong adaptability and flexibility, Can enter a relatively narrow space and can cross obstacle, up and down stairs, up and down slope, Can even movement on the surface of the uneven soil preparation, in the rescue and relief, demining, adventure, recreation, and many aspects such as the military has a good application prospect.

   Based on quadruped robot as the research object, the main content included:

1.This paper expounds the research background and significance of the quadruped robot, the brief analysis of the status quo and tendency of the development of robot at home and abroad.

2. Establish a four-legged robot 3 d overall structure (SOLIDWOKS simple model), and the analysis and calculation for the legs and joints of the robot.

3. Quadruped robot dynamics model is established, the data and formulas are provided by the process of 2, mainly using the method of Lagrange balance modeling.

4. Using ABAQUS software in finite element simulation of the model, the parameters of the look-up table design, so as to analyze joint torque required kinetic energy, and leg friction, singular state parameters, etc. I will be        on display in the attachment the specific data and curves.

In this paper, the research content will provide mathematical model for the follow-up of the robot control algorithm, also for structure optimization design of robot joint drive motor and reducer selection provides theory basis.
