摘要
以平面二自由度冗余驱动并联机器人为研究对象,分别进行了逆运动学分析和正运动学分析,得出并联机器人的8种逆运动学解析解。运用影响系数法建立了系统的一阶影响系数矩阵,并设定了速度性能指标。对应8种不同的机构位形,绘制了相应的速度性能图谱,探讨了不同的机构安装方式对机构速度性能的影响,指出了较优的机构安装方式,为今后研究、设计和安装该类型并联机器人提供了依据。
A planar 2-DOF redundantly actuated parallel robot is chosen as the object of study in this paper. Analysis of the inverse kinematics and the forward kinematics has been accomplished. There are 8 solutions for the inverse kinematics. The first order kinematic influence coefficient matrix has been set up using the influence coefficient method. Then the corresponding performance atlas has been plotted. The effects of the installation method on velocity performance have been discussed, and the optimal way has been pointed out. This paper has provided a basis for the design of this type of parallel robots.
