Robot controller system

Abstract

A robot controller system includes a robot including a first actuator and a second actuator, a main controller for driving the first actuator, and a sub-controller for driving the second actuator. The main controller includes an actuator controller for computing a target drive amount for the first actuator to generate first control data including the target drive amount for the first actuator and for computing a target drive amount for the second actuator to generate second control data including the target drive amount for the second actuator, a first actuator driver for generating a first drive signal based on the first control data and providing the first actuator with the first drive signal to drive the first actuator, and a first input/output unit providing the sub-controller with the second control data. The sub-controller includes a second actuator driver for generating a second drive signal based on the second control data and providing the second actuator with the second drive signal to drive the second actuator, and a second input/output unit for providing the second actuator driver with the second control data from the first input/output unit.
