Abstract

The invention discloses an EtherCAT bus-based control system for a three-axis parallel mechanical arm. The control system comprises a PC linux master station, a human-computer interaction interface, an EtherCAT controller I, an EtherCAT controller II, an input module, a storage module, a generation module, a motion controller module, a three-axis parallel mechanical arm motion module and a visualdetection system module; the PC linux master station comprises an Ethernet card; the Ethernet card is connected with the EtherCAT controller II and the human-computer interaction interface; the EtherCAT controller II is connected with the three-axis parallel mechanical arm motion module through the motion controller module; the man-machine interaction interface is connected with the input module and the EtherCAT controller I; and the EtherCAT controller I is connected with the motion controller module through the generation module. With the control system adopted, the real-time performance andstability of the control of the three-axis mechanical arm can be effectively guaranteed. The control system has the advantages of low cost and good expansibility.

Description

technical field [0001] The invention relates to the technical field of manipulator control, in particular to an EtherCAT bus three-axis parallel manipulator control system. Background technique [0002] The robotic arm is the most widely used automatic mechanical device in the field of robotics. It can be seen in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although their shapes are different, they all have a common feature, that is, they can accept instructions and precisely locate a certain point in three-dimensional space for operation. [0003] With the development of industrial technology, the control of the mechanical arm puts forward higher and higher requirements for speed and precision, and puts forward high requirements for the transmission speed of the field bus used for servo motion control and the real-time performance of the bus interface. In order to ensure that the robot ac...
