Abstract

This paper presents a new family of fully-parallel robots producing motions of the Schoenflies displacements subgroup (three translations and one rotation about a given axis in world coordinates) for high-speed handling and machining. First, the structure's ability to provide this four-degrees-of-freedom motion is presented. Then, two of its possible designs are analyzed: the symmetrical and the asymmetrical one. Constructive designs are then presented. Some of the prototype's preliminary control results are given to prove the H4 robot's efficiency.

一种新型高速四自由度并联机器人的合成与建模问题
本文提出了一种新的全并联机器人,用于高速搬运和加工,产生schoenfly位移子群(在世界坐标中绕给定轴三次平移和一次旋转)的运动。首先,给出了该结构提供四自由度运动的能力。然后,分析了两种可能的设计:对称设计和不对称设计。然后提出建设性的设计。给出了样机的一些初步控制结果,以证明H4机器人的有效性。
