摘要
Delta型机器人是一种三自由度纯平动并联机构,介绍了应用Simulink的SimMechanics模块集对Delta平台进行仿真研究的方法。运用SimMechanics模块对并联机器人进行建模,并根据机构的几何特性建立运动学逆解求取模块,给出动平台规划运动轨迹,通过运动学逆解求取模块生成机构驱动轴输入运动信号,对机构模型进行运动仿真。仿真结果表明,所建立的机械模型和逆解求取模块以及轨迹跟踪都符合实际系统特性,仿真方法高效、实用。
Delta robot is a 3-DOF(degree of freedom) parallel mechanism.This paper introduces a simulation method based on SimMechanics in Simulink.The Delta mechanism is modeled using the SimMechanics modules,and the inverse kinematics is solved according to the geometry characters of the robot.Given a motion trajectory,the active actuators motion signal can be obtained using the inverse kinematics solver module.Simulation experiment is also carried out.
