The function of the robot control system is to receive detection signals from sensors and drive each motor in the robot arm according to the requirements of the operation task Just as we humans need to rely on our own senses for our activities, the robot motion control cannot be done without sensors. The robot needs sensors to detect various states. The internal sensor signals of the robot are used to reflect the actual motion of the robot arm joints, and the external sensor signals of the robot are used to detect changes in the working environment.
Components of industrial robot control system
1、Control computer: the scheduling and command mechanism of the control system. Generally, it is a microcomputer, microprocessor with 32-bit, 64-bit, etc. Such as Pentium series CPU and other types of CPU.
2、Teaching box: It teaches the robot's working trajectory and parameter setting, as well as all human-computer interaction operations, and has its own independent CPU and storage unit, and realizes information interaction with the main computer in the form of serial communication.
3、Operating panel: It is composed of various operation buttons and status indicators, and only completes the basic function operation.
4、Hard disk and floppy disk storage: peripheral memory for storing robot work programs.
5、Digital and analog input and output: input or output of various status and control commands.
6、Printer interface: record the various information that needs to be output.
7、Sensor interface: used for the automatic detection of information to achieve robot soft control, generally force, tactile and visual sensors.
8、Axis controller: to complete the robot's joint position, speed and acceleration control.
9、Auxiliary equipment control: used for the control of auxiliary equipment with the robot, such as hand claw position changer, etc.
10、Communication interface: realize the information exchange between the robot and other devices, generally serial interface, parallel interface, etc.
11、Network interface
1）Ethernet interface: It can realize direct PC communication of several or single robots through Ethernet, with data transmission rate up to 10Mbit/s. After application programming with windows library function directly on PC, it supports TCP/IP communication protocol and loads data and program into each robot controller through Ethernet interface.
2）Fieldbus interface: It supports many popular fieldbus specifications, such as Devicenet, ABRemoteI/O, Interbus-s, profibus-DP, M-NET, etc.
