摘要

本文提出了一种计算柔性物体协同机械手逆动力学和正动力学模型的方法。为了求解该系统的动力学问题,将封闭链划分为两个子系统,一个是柔性子系统,代表物体,另一个是刚性子系统,代表两个机械手的树形结构。通过计算末端执行器传递的扳手来连接两个子系统。得到了动力学模型的解析解。提出的解决方案导致了多个机械手抓取对象的分类。

Dynamic modeling of cooperative robots holding flexible objects
In this paper a method of calculating the inverse and direct dynamic model of cooperative manipulators handling flexible objects is presented. In order to solve the dynamics of this system, the closed chain is divided into two subsystems, one is flexible, representing the object and the other is rigid, representing the tree structure of the two manipulators. The two subsystems are connected by calculating the wrench transmitted by the end effectors. An analytic solution is obtained for the dynamic model. The proposed solution leads to a classification of objects grasped by multiple manipulators.
