Method for calibrating a touch screen panel using an industrial robot, system using the same, industrial robot, and touch screen

摘要

This provides a method for calibrating the touch screen panel (11) and the system (1), industrial robot (10) and touch screen panel (11) using it. The method includes (a) defining at least one area (20) of the touch screen (112) having a predetermined accuracy for position measurement; and (b) at least one area of the touch screen (112) ( 20) recording a plurality of kinematic parameters of the industrial robot (10) on a plurality of first touch points on the top; (c) a plurality on the at least one area (20) of the touch screen (112); Recording a plurality of first position values on the first touch point of the robot, and (d) motion of the industrial robot (10) using the kinematic parameters and using the first position value. Determining first calibration data for the geometric model; and (e) computationally correcting the kinematic model error of the industrial robot (10) using the first calibration data. And (f) recording a plurality of second position values on a plurality of second touch points on at least one area (20) with at least a portion of its boundary extending outwardly, (g) ) Determining second calibration data for the touch screen (112) using the kinematic parameters and using the second position value; and (h) using the second calibration data. The step of calculating the position measurement error of the touch screen (112) computationally and the steps (b) to (h) are repeated for different postures of the industrial robot (10). And 10) repeating until no more significant improvement in error correction of the kinematic model occurs.
