A path planning method for a surface inspection system based on two-dimensional laser profile scanner

Abstract

In this article, a method for two-dimensional scanning path planning based on robot is proposed. In this method, a section division algorithm based on neighborhood search method for scanning orientation determination is firstly produced. The scanning paths which meet constraints of the system are then generated. Finally, the experiment is carried out on robot-based scanning platform. The two-dimensional data from scanner and the robot position are combined to form three-dimensional surface data of measured workpiece. The experiment results verify the effectiveness of proposed method.

Ultrafast Laser Surface Functionalization and Route to Industrial Applications: Computer-Vision-Based Path Planning

“…However, upscaling local laser texturing on large and freeform surfaces remains a challenge for the deployment of the technology at an industrial level. In this concern, path planning [1,2] appears as a crucial preliminary step to succeed in an accurate and fast process. In the present work, we develop a methodology delivering an optimal scan path from a 3D point cloud on the surface to be laser treated.…”

Design and Analysis of Jittering Mitigator for Robot Arm-Tip

“…Previous studies found that the arm-tip jittering of a robot can seriously affect its trajectory accuracy and kinematic stability under typical working conditions. There are various factors influencing arm-tip jittering [7][8][9][10][11][12][13][14][15][16][17], including resonance of the robot arm [7,8], stiffness of the transmission gear in retarder and robot links [9,10], mismatch between the motor output torque and the actual demand of joints, installation accuracy, transmission gap [11], etc.…”
