Abstract This paper proposes a 3D LiDAR simultaneous localization and mapping system for indoor unstructured scenes to improve the robustness accuracy of automated guided vehicles. First, in point cloud preprocessing stage, curve voxel clustering method considering rarity clouds is proposed, which effectively distinguishes adjacent objects while handling outliers, achieves accurate clouds. Next, feature extraction curvature evaluation based on principal component analysis used ensure quality...
Abstract Most studies on path planning of robotic arm focus obstacle avoidance at the end position arm, while ignoring joint linkage, and method has low flexibility adaptability. This paper proposes a algorithm for overall 6-DOF that is based improved A* artificial potential field method. In first place, an proposed to address deficiencies conventional algorithm, such as large number search nodes computational efficiency, in planning. The enhanced new node strategy local optimization method,...
Abstract This article proposes an online kinematic calibration method for simultaneous five-axis motion solving the problems of low kinematics accuracy and a highly complex platform. First, ArUco markers are used in vision system large stroke detection, while models platform established based on screw theory. parameter identification along five axes, using monocular camera as measurement tool. Furthermore, stability effectiveness algorithm verified by simulation experiment. Specifically,...
Abstract Geometric error calibration of the rotary axis is an important and effective method for improving five-axis dispensing equipment's motion processing accuracy. In most previous studies, simultaneously identifying geometric errors multiple rotation axes using traditional precision measuring instruments often challenging. This paper proposes a simultaneous model based on AprilTag target visual framework. The can synchronously identify in case multi-axis linkage. proposed kinematic...
