Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0032] The present invention is mainly a high-reliability control technology for multi-robot systems. Firstly, it proposes multi-robot system working group division and physical topology design for the controlled system, which is the root of high-reliability systems. After the robot has a physical structure, it needs to be controlled by a controller. Based on the above ideas, the present invention proposes a multi-robot system and its communication system.

[0033] Such as figure 1 As shown, in a...

Abstract

The invention provides a multi-robot system and a communication system thereof. The multi-robot system comprises a working group composed of working robots and a standby working group composed of standby robots, the working or standby robots in the working group or the standby working group are the same in hardware structure and close in physical positions, and the robots in each group is physically replaceable. The client/server and end-to-end mixed communication system in explicit communication is high in the expandability, and easy to realize different application scenes; the system is also based on Ether CAT, so that instantaneity, expansibility and network bandwidth are compatible; and the robots do not communicate with one another directly, instead, all the robots communicate with a main controller. The main controller integrates feedback information of the robots with sensor data, process the data, and notifies the robots to implement different operation logics or fault recovery processes.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a multi-robot system and a communication system thereof. Background technique [0002] Since the 1970s, industrial robots have become an important technology in the industrial field. Worldwide, the application of industrial robots has set off a climax. With the continuous increase of labor costs and the rising labor costs of enterprises, industrial robots have objective development needs. At the same time, the application fields of industrial robots have gradually expanded from the automotive industry to electronics manufacturing, food and drug and plastic industries. In order to complete complex processes, industrial robots work together in many cases. Therefore, industrial robots often work in the form of multi-robot systems. It is inherently difficult for multiple robots to work together. This difficulty lies in the information synchronization and behavior coordination of ...
