Automatic machine vision-based manipulator used for button cell sorting has high academic value. Firstly, a detailed analysis of the visual system, using an image-based visual servo control method, is provided, so as to establish a set of button batteries automatic sorting manipulator platform. the detail composition of this platform is introduced in this paper. Through analysis of PID control method, a mathematical model is established, and its motor control is simulated.Experimental results show that, the platform of an automatic manipulator system has char high accuracy and higher real-time characteristic.

This describes the application of a visual servo control method to the microrobotic manipulation of polymer beads on a two-dimensional fluid interface. A microrobot, actuated through magnetic fields, is utilized to manipulate a non-magnetic polymer bead into a desired position. The controller utilizes multiple modes of robot actuation to address the different stages of the task. A filtering strategy employed in separation mode allows the robot to spiral from the manipuland in a fashion that promotes the manipulation positioning objective. Experiments demonstrate that our multiphase controller can be used to direct a microrobot to position a manipuland to within an average positional error of approximately 8 pixels (64 µm) over numerous trials.
