“…There are many desirable characteristics for a kinematic model, but when considering kinematic models constructed aiming at using in robot calibration procedures three are mostly important: completeness, continuity and minimality (Motta, 2005;Albright, 1993). Completeness is the ability of a kinematic model to describe all possible spatial geometric joint configurations of a robot.…”

Using the previous two conventions (Denavit-Hartemberg and Hayati-Mirmirani) and taking into account the requirements of a kinematic model (completeness, continuity and minimality), the singularity-free approach discussed was applied for the assignment of coordinate frames and for the definition of which error parameters should be included in the kinematic model (Motta, 2005). Using this approach and the mechanical drawings of the IRB2000 (ABB, 1993), a kinematic model representing mathematically this robot was constructed.…”

“…Later, Elatta et al [3] replenished the contributions during the interval. However, level-1 [4] and level-2 [5], [6], [7], [8], [9], [10], [11] calibration methods were proved to be more popular in factory, owing to their excellent costefficiency. Level-3 calibration [12], [13], which enables the online fast trajectory tracking, yet, is rarely used due to the high cost of measuring.…”
Abstract. Calibration techniques played an essential role of improving the pose accuracy of the industrial robot before delivery. Due to the intense competition among the industrial robot market, numerous complicated calibration approaches, which were classified into 3 levels, had been successfully developed. Yet, in practical, level-1 and level-2 calibration, other than higher level, were often used in factory for the sake of cost-effective matter. And most of the researches and applications were focused on enhancing the position accuracy while the orientation accuracy was neglected. Considering the requirement of painting process and efficiency of calibration, we proposed a practical level-2 calibration method for a spray painting robot which was designed by Industrial Robot Research Center Co. Ltd. The measuring system consisted of API laser tracker and an orientation testing End-Effector. After identification and compensation process, we found this method was more effective compares to Zero-Offset method and Direct Calibration method with the relatively competitive consumption time.
