Control method of robot system and apparatus for realizing the same
First Claim
1. A method for controlling a robot system having a commander and a plurality of modules, comprising the steps of:
- generating one or more requests to transmit one or more messages from a source module to a destination module;
inputting the transmission requests to the commander;
placing the transmission requests into a sequential list of transmission requests;
writing the messages into queue buffers, corresponding to the destination modules, until the sequential list is depleted; and
transmitting one messages from each of the queue buffers to the corresponding destination modules in a predetermined order.

Abstract
When a robot system has a program module group within a central control unit for performing required program processing, the associated portions of the robot, and a plurality of peripheral control modules for controlling the associated portions of the robot, a communication module is provided to perform communication between the modules. In the system there is provided with a queue buffer for sequentially storing the present status information, a source module name, and the message. The communication module monitors transmission from the respective module, stores a message in the queue buffer, forms a transmit request list, sequentially receives the destination module name and the message in accordance with a reception procedure of the source module, and stores the source name module and the message in the queue buffer in accordance with the destination module. Subsequently, the communciation module sequentially searches the message to be transmitted in a queue buffer, and checks the status of the destination modules. If the status of a destination module is set in an enabled state, the message is transmitted in accordance with a transmission procedure of the destination module. If not, the message is left in the queue list and will be transmitted in the next transmission cycle.
