New applications in small part assembly put forward higher requirements on robot's absolute accuracy, which can be effectively improved by robot calibration. However, existing methods are either with expensive equipment such as laser tracker, or time-consuming due to tedious manual operations. In this paper, we present a robot calibration solution using touch panel. It is cost-saving and can quickly improve or recover the robot absolute accuracy in the interested working area. We demonstrate its calibration performance by experiments with ABB Yumi robot.
