1. Manipulator - the brain of the Epson robot
Controller (English name: controller) refers to the main command device that controls the start, speed regulation, braking and reverse of the motor by changing the wiring of the main circuit or the wiring of the control circuit and the resistance value in the circuit according to a predetermined sequence. It is composed of program counters, instruction registers, instruction decoders, timing generators and operation controllers, and it is the "decision-making body" that issues commands, that is, completes the operation of the entire computer system to complete the coordination and command. Commonly used controllers in automated factories include PLC, industrial computer, etc.
ProgrammableLogic Controller (PLC), which selects a type of programmable memory for its internal storage programs, executes user-oriented instructions such as logic operations, sequential control, punctuality, counting and arithmetic operations, and controls various types of machinery or production processes through digital or analog input/output.
Industrial computer (IPC) is an industrial control computer, which is a general term for the detection and control of the production process, mechanical and electrical equipment, and process equipment by selecting the bus structure. Industrial computers have important computer characteristics and characteristics, such as computer CPU, hard disk, memory, peripherals and interfaces, and have operating systems, control networks and protocols, computing capabilities, and friendly human-machine interfaces. The products and skills of the industrial control industry are very special, which are intermediate products, and are the supply of reliable, embedded and intelligent industrial computers for other industries.
2. Robot ontology - the resolute executor of Epson robots
A robot is a machine device that performs tasks automatically. It is capable of being commanded by humans, running pre-programmed procedures, and acting according to principles developed with AI skills. Its task is to assist or replace human operations, such as in the production industry, construction, or hazardous work. Epson robots are generally composed of actuators, drives, detection devices, control systems and complex machinery.
3. Servo motor - the power muscle of the Epson robot
Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is a kind of auxiliary motor indirect transmission device. The servo motor can make the control speed and azimuth accuracy very precise, and can convert the voltage signal into torque and speed to drive the control target. The rotor speed of the servo motor is controlled by the input signal, and can respond quickly, in the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc., which can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors, and its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of torque.
The servo system is an automatic control system that enables the output control of the object's orientation, orientation, and condition to follow the arbitrary change of the input target (or given value). The servo mainly relies on the pulse to position, basically it can be understood in this way, the servo motor receives a pulse, it will rotate the viewpoint corresponding to the pulse of 1, and then realize the displacement, because, the servo motor itself has the function of sending out pulses, so the servo motor rotates a viewpoint, will send out the corresponding number of pulses, in this way, and the pulse borne by the servo motor forms a response, perhaps called a closed loop, so that the system will know how many pulses are sent to the servo motor, and how many pulses are received together, so that It can control the rolling of the motor very well, and it can reach 0.001mm.
DC servo motors are divided into brushed and brushless motors. The brush motor has low cost, simple structure, large starting torque, wide speed regulation scale, simple operation, and needs protection, but the protection is inconvenient (changing carbon brushes), electromagnetic disturbance occurs, and there are requirements for the environment. As a result, it can be used in cost-sensitive general industrial and residential applications.
