The first are ordinary high-precision AC servos. However, robot servo accuracy requirements and response times are relatively high. In fact, most brands of high-end servo systems on the market can do it!
The so-called difference is nothing more than:
1. The robot needs a bus-type servo (high-end), not the conventional pulse control (low-end);
2. Encoder accuracy and standard. In practice, there are many ENDAT encoders;
Because of the control structure of the robot, it can be basically divided into three points:
1. The computing power of the controller is high,
2. The bus communication speed between controller and servo is fast (data transmission volume will be very large),
3.High precision of servo;
With the current development of industrial control technology, it should be said that many brands can meet the requirements. The core of robot control is not in the hardware, but in software, such as the CNC and the communication library between the CNC system and external instructions, and some other control algorithms, which need to be accumulated by the robot industry for a long time.
