If there are only senses and muscles, the human limbs still can't move. On the one hand, because the signals from the senses have no organs to receive and process, and on the other hand, because no organs emit nerve signals, they drive the muscles to contract or relax. Similarly, if the robot has only sensors and drivers, the robotic arm will not work properly. The reason is that the signal output from the sensor does not work, and the driving motor does not get the driving voltage and current. Therefore, the robot needs to have a controller , which uses hardware and software to form a control system. Therefore, the controller has an " industrial robot brain". Said.
What is a robot control system?
The function of the robot control system is to receive the detection signal from the sensor. According to the requirements of the operation task, each motor in the robot arm is driven like our human activity depends on its own senses. The motion control of the robot cannot be separated from the sensor. The robot needs to use sensors to detect various states. The robot's internal sensor signal is used to reflect the actual motion state of the robot arm joint, and the robot's external sensor signal is used to detect changes in the working environment.
So the robot's nerves combined with the brain to form a complete robotic control system.
What are the aspects of the robot's motion control system?
Actuator---- servo motor or stepper motor;
Drive mechanism----servo or stepper drive;
Control mechanism----motion controller, algorithm operation control for path and motor linkage;
Control mode----With fixed execution mode, then program the fixed parameters to the motion controller; if there is a vision system or other sensors, according to the sensor signal, program the unfixed parameters to the motion control Device
