Technical Principle of Industry Robot

    The robot control system is the brain of the robot and the main factor that determines the function and performance of the robot.

    The main task of industrial robot control technology is to control the movement position, posture and trajectory, operation sequence and action time of industrial robots in the work space. It has the characteristics of simple programming, software menu operation, friendly human-computer interaction interface, online operation prompts and convenient use.


Key technologies include:

    Open and modular control system architecture: using distributed CPU computer structure, divided into robot controller (RC), motion controller (MC), photoelectric isolation I/O control board, sensor processing board and programming display Teaching boxes, etc. The robot controller (RC) and the programming teaching box communicate through the serial port/CAN bus. The main computer of the robot controller (RC) completes the robot’s motion planning, interpolation and position servo, as well as main control logic, digital I/O, sensor processing and other functions, while the programming teaching box completes information display and key input.

    Modular and hierarchical controller software system: The software system is built on the open source-based real-time multi-tasking operating system Linux, and adopts a layered and modular structure design to realize the openness of the software system. The whole controller software system is divided into three layers: hardware driver layer, core layer and application layer. The three levels face different functional requirements and correspond to different levels of development. Each level of the system is composed of several modules with relatively opposite functions. These functional modules cooperate with each other to realize the functions provided by this level.

    Robot fault diagnosis and safety maintenance technology: Diagnosing robot faults and performing corresponding maintenance through various information is the key technology to ensure the safety of robots.

    Networked robot controller technology: the current robot application engineering is developing from a single robot workstation to a robot production line, and the networking technology of robot controllers is becoming more and more important. The controller has networking functions of serial port, field bus and Ethernet. It can be used for communication between robot controllers and between robot controllers and host computers, which is convenient for monitoring, diagnosis and management of robot production lines.
