“…Takarics [12] attempted to use the stereo vision technology to program a weld trajectory based on the intelligent space concept using two fixed cameras. The weld seam is recognized in two images by edge detection algorithms and the path trajectory was generated by the 3D reconstruction from both images.…”

Abstract"Although an automated flexible production cell is an intriguing prospect for small to median enterprises (SMEs) in current global market conditions, the complexity of programming remains one of the major hurdles preventing automation using industrial robots for SMEs. This paper provides a comprehensive review of the recent research progresses on the programming methods for industrial robots, including online programming, offline programming (OLP), and programming using Augmented Reality (AR). With the development of more powerful 3D CAD/PLM software, computer vision, sensor technology, etc. new programming methods suitable for SMEs are expected to grow in years to come.

“…This gives rise to difficulties, errors and even failures of the processing of weld seam images. However, intelligent recognition algorithms, as discussed by Mehrdad Bahrami-Samani, Maryam Agahi and S. Ali A. Moosavian [26], Béla Takarics, Péter T. Szemes, Gyula Németh, and Péter Koro ndi [28], can eliminate some of these negative effects. As an additional benefit, intelligent recognition algorithms are an effective way to improve recognition accuracy and increase image processing performance.…”

This paper presents algorithm ingenerating trajectory for sealant process using captured image. Cartesian robot as autosealant in manufacturing process has increased productivity, reduces human error and saves time. But, different sealant path in many engine models means not only different trajectory but also different program. Therefore robot with detection ability to generate its own trajectory is needed. This paper describes best lighting technique in capturing image and applies edge detection in trajectory generation as the solution. The algorithm comprises image capturing, Canny edge detection, integral projection in localizing outer most edge, scanning coordinates, and generating vector direction codes. The experiment results show that the best technique is diffuse lighting at 10 Cd. The developed method gives connected point to point trajectory which forms seala nt path with a point to next point distance is equal to 90° motor rotation. Directional movement for point to point trajectory is controlled by generated codes which are ready to be sent by serial communication to robot controller as instruction for motor s which actuate axes X and Y directions.
