With the increasing number of players in the domestic industrial robot industry, robot manufacturers, especially domestic collaborative robot manufacturers, are seeking the most suitable main control chip for themselves. The previously listed series include those that build powerful cores, those that configure powerful communication functions, and those that integrate advanced vision. The single determining factor no longer exists among manufacturers, who often need to consider expanding robot functions and controlling overall machine costs. The motion control of industrial robots has evolved from the most basic on\/off constant speed motors to the complex multi axis servo drive in robot technology. High performance robot drive control chips are constantly emerging and developing rapidly.
