Common robot controllers and basic functions are explained

As one of the most core parts of industrial robots, robot controller has a decisive impact on the performance of robots and affects the development of robots to a certain extent. Commonly used robot controllers are: 1. PLC controller; 2. MCU controller; 3. Computer host CPU controller. The basic functions of the robot control system are as follows: 1. Control the moving position of the end effector of the robot arm (that is, control the point and moving path of the end effector); 2. Control the motion attitude of the robot arm (that is, control the relative position of two adjacent moving components); 3. Control the motion speed (that is, control the law of the movement position of the end effector changing with time); 4. Control motion acceleration (that is, control the speed change of the end effector during movement); 5. Control the output torque of each power joint in the manipulator: (that is, control the force applied to the operating object); 6. With convenient man-machine interaction function, the robot can complete the specified tasks through memory and reproduction; 7. Enable the robot to detect and feel the external environment. Industrial robots are equipped with sensors such as vision, force sense and touch to measure, identify and judge changes in operating conditions.
