“…This method is not efficient and less robust. Wu et al [14] used a camera and a line laser to reconstruct the 3D data of the sole and could not realize the one-time 3D reconstruction with low working efficiency. Zhu et al [15] proposed an automatic generation method for shoe sole spraying trajectory, which converts the 3D point cloud of shoe soles into 2D depth images, so the accuracy and robustness of this method were not high.…”

In this paper, we propose a monocular encoded structured light-based path generation method for sole roughening, and the obtained paths are used to guide a six-degree-of-freedom (DOF) robot for automatic roughening, which greatly improves the quality and efficiency of roughening. First, we selected monocular structured light as the vision system. To improve the calibration and reconstruction accuracy of the projector, we used an improved Three-Wavelength Phase-Shift Profilometry technique (TWPSP) to calibrate the projector, and the accuracy was improved by 26.29% compared with the conventional method. Then, we proposed a Three Coordinate Scanning Weighted-Principal Component Analysis (TCSW-PCA) algorithm as the path planning system. The experimental results show that the six-DOF-robot can automatically roughen different types of soles according to the generated roughening paths, and the processing efficiency and finished product quality of our proposed method of automatic roughening are better than other roughening methods, with an average improvement of 42% in roughening effect and an average improvement of 30.52% in roughness.

In this paper is presented a Virtual Reality application that can be used for automatic generation of robot trajectories for spray painting operations conducted on products with complex surfaces. The trajectory generation for robots that perform painting operations of complex curved surfaces was achieved by implementing a generic algorithm capable of maintaining an optimal distance for painting. The distance between the effecter of the robot and the surface of the CAD model, used to compensate and maintain an optimal painting distance, is determined by a "rayhit" collision detection algorithm that allows the detection of the contact between a linear segment and the mesh of the virtual object. To visualize in the virtual environment the deposition of paint layers, an algorithm was implemented that is based on mapping techniques for dynamically generated textures on the surface that is being painted. A VR software application was developed for generating and visualizing the trajectories of a KUKA robotic system that performs the activity of painting a complex curved product.

Robotization in the footwear sector is a major challenge for the industry with difficulties present due to the inherent adaptive needs of some of the automated tasks performed by robotic arms. One of those of particular concern is collision prevention: working with those robots in automated on-line environments, considering they have limited awareness of the environment, may lead to dangerous situations with the movement of the robot along the calculated paths. To overcome this problem, a collision prevention layer based on a custom robotic software simulator is presented and justified in this paper to be used on automated shoe sole adhesive spraying cells. The performed experiments prove the feasibility of the proposed method in a real scenario with the speed and precision required by the automated task.
