Abstract: The robot control system based on Windows CE system collects the signal feedback of sensor group and limit switches which are installed on all kinds of machine tools and gantry robot continuously.And also the signals which are collected are sent to the robot control system.Than the robot control system processes and analysis the signals which are received before, judges the logical relationship between each other, determine the action sequence.Finally the robot control system sends the command signals to each work units.Therefore the robot control system and all kinds of machine tools can achieve the communication and act logically with each other, which make sure the whole product line run safely and efficiently.
