变拓扑桁架(VTT)是一种新型的自重构机器人,它可以根据任务或环境的要求重新配置其桁架形状和拓扑结构。运动规划和避免自碰撞是困难的,因为这些系统通常有几十个自由度,复杂的交叉并联驱动。对于VTT,存在两种不同类型的形状改变动作:几何重构和拓扑重构。本文重点研究了几何重构动作。提出了一种新的单元分解方法,该方法基于一种快速而完整的方法来计算桁架中节点的无碰撞空间。一个简单的形状变形方法,快速创建运动路径的重新配置移动一个节点的时间。
The Variable Topology Truss (VTT) is a new class of self-reconfigurable robot that can reconfigure its truss shape and topology depending on the task or environment requirements. Motion planning and avoiding self-collision are difficult as these systems usually have dozens of degrees-of-freedom with complex intersecting parallel actuation. There are two different types of shape changing actions for a VTT: geometry reconfiguration and topology reconfiguration. This paper focuses on the geometry reconfiguration actions. A new cell decomposition approach is presented based on a fast and complete method to compute the collision-free space of a node in a truss. A simple shape-morphing method is shown to quickly create motion paths for reconfiguration by moving one node at a time.
