The robot vision technology was applied to the target location of the 3-DOF parallel manipulator,and a mathematical model of the position inverse solution for the manipulator with 3-DOF was established.The LabVIEW software was used for programming and Matlab software was used to simulate the manipulator trajectory planning algorithm,thus the simulation of the whole working process of the grasping task was implemented.Finally,the prototype of 3-DOF parallel manipulator was made and tested.By comparing the experimental data with the theoretical design,the correctness of the theoretical analysis and model is proved.It is also proved that the introduction of machine vision technology can increase the intelligent level and positioning precision of the parallel manipulator.
