Service Robot Decoupled Spherical Arm Movement Control Method

为了在适应极端条件下,服务机器人手臂能够满足高集成度和高性能的特殊要求,提出了一种基于解耦球型手腕的七自由度机械机构。首先分析七自由度机械手臂的机械结构特点,利用MDH法建立了机器人各个轴的相关坐标系。然后,利用牛顿迭代和传递逆方程法反向解析了手臂,手腕机理确保手腕紧性和灵活性的工作空间。最后,从电机控制和模块方向设计了七自由度软件流程。上述理论确保了该机器人机构能平稳并且能够灵活实现各个自由度的运动控制。

In order to adapt to extreme conditions,service robot arm to meet the high level of integration and performance of special requirements,this paper presents a spherical wrist based on the decoupling of Seven-freedom mechanical system.It analyzes the characteristics of the mechanical structure of Seven-freedom mechanical arm,the establishment of relevant coordinates of each robot axis using MDH law.Then,using Newton iteration and inverse transfer equation method reverse analysis arm,wrist wrist mechanism to ensure compactness and flexibility of the work space.Finally,from the direction of the motor control module design and seven degrees of freedom of software processes.Above theory ensures that the robotic mechanism smoothly and flexibly implement various degrees of freedom of motion control.
