Design of High-Performance Six Axis Industrial Robot Controller

The controller is the core component of industrial robots, equivalent to the robot's “brain”. In response to the weak software foundation of industrial robot controllers in China, which makes it difficult to meet the high-end application needs of robots, research on the architecture of industrial robot controllers has been carried out. The design work of teaching pendant software and hardware, EtherCAT bus communication software, and motion control software has been completed. The designed six-axis industrial robot controller has basic functions such as main programming instruction support, safety control, digital and analog 1O expansion, external axis, and multiple bus expansion capabilities, which can meet the high-end application requirements of industrial robots in terms of functionality, performance, and scalability.
