Robot coordinated control method and system
First Claim
1. A robot coordinated control method comprising steps of communicating among a plurality of robot control devices each generating an operation basic period signal at a predetermined period and controlling at least one robot synchronized with the operation basic period signal, and making said robots controlled by said plurality of robot control devices coordinately operate,wherein said robot coordinated control method further comprises steps of:
- transmitting a reference signal from one of said plurality of robot control devices to the other robot control devices; and
synchronizing the timing of generation of the operation basic period signal in each of said other robot control devices with the timing of generation of the operation basic period signal in said one of said plurality of robot control devices, based on a time interval from generation of the operation basic period signal until transmission of the reference signal in said one of said plurality of robot control devices, a time interval from generation of the operation basic period signal in each of said other robot control devices until reception of the reference signal by each of said other robot control devices, and a communication delay time required for communication between said one of said plurality of robot control devices and each of said other robot control devices.

Abstract
A reference signal is transmitted from one of a plurality of robot control devices connected by communication connecting device to the other robot control device. The timing of generation of an operation basic period signal in each of the other robot control devices is synchronized with the timing of generation of an operation basic period signal in the one of the plurality of robot control devices, based on a time interval from generation of the operation basic period signal until transmission of the reference signal in the one of the plurality of robot control devices, a time interval from generation of the operation basic period signal until reception of the reference signal in each of the other robot control devices, and a communication delay time required for communication between the one of the plurality of robot control devices and each of the other robot control devices.
