Abstract

The present invention relates to a modularized control system for an articulated robot, which is based on CAN bus. The present invention is characterized in that the control system comprises a PC, a CAN intelligence interface card, a plurality of control modules (wherein, each control module controls one articulation of the robot), and a CAN bus for connecting the modules and the CAN intelligence interface card. In the control system of the present invention, a two circuit CAN intelligence interface card is connected to the PC by an USB interface at one end, and is connected to the CAN bus by a CAN bus interface at the other end; the control module is connected to the CAN bus. The system and method of the present invention has excellent portability, short development cycle, low cost, regrouping property, fungible property, openness and high stability, and can execute on-line monitoring to robot.

Description

technical field [0001] The invention relates to a robot control system, in particular to a CAN bus-based modular joint robot control system. Background technique [0002] At present, the control systems of most robots are based on specific controlled objects, and are developed and designed using special hardware platforms, special systems and operating languages, and their structures are mostly closed. This makes it difficult for users or third-party developers to expand the functions of the robot's control system as needed, and to increase, decrease, and transplant the software and hardware of the control system. If the various functions of the control system are concentrated together without a clear division of structure and function, then a failure of one function will inevitably affect the reliability of the entire control system, and even cause the entire system to fail. The cost of the control system, installation and maintenance costs will increase accordingly. Ther...
