To solve the problem that robot often collides with obstacles such as branches around fruit during picking due to its inability adapt growing environment, this paper proposes an apple-picking path planning algorithm based on improved PSO. The main contents of are: firstly, and surrounding are extracted from 3D point cloud data, direction is calculated; then surface used establish spatial model obstacles; finally, particle swarm optimization (PSO) proposed plan obstacle avoidance trajectory...
Research into autonomous (robotic) apple picking has not yet resolved the problem of finding optimal orientation. Robotic efficiency, in terms all available apples without loss or damage, remains low. This paper proposes a method determining orientation relative to target fruit and adjacent branches from point cloud surrounding space. The mechanism is then able avoid accurately grasp order pick it. first identified by YOLOv3 detection algorithm, space it obtained. random sample consensus...
Purpose The purpose of this article is to solve the issue that apple-picking robots are easily interfered by branches or other apples near target apple in an unstructured environment, leading grasping failure and damage. Design/methodology/approach This study introduces system units robot prototype, proposes a method determine direction via 3D point cloud data optimizes path planning according calculated picking direction. Findings After field experiments, average deviation from desired...
For the marine industry, resistance reduction can reduce energy consumption and achieve protection of environment. The use air lubrication to ships is one most important ways. With this technology, high-speed cavity crafts show immense potential as they be utilized in various activities, such emergency rescue, supply, maritime security. Through experiments, study presents an in-depth analysis effects bubble chamber pressure initial stern inclination on at different speeds. results that has a...
The uncertainty and extremity of ocean conditions make the design marine structures a challenging process. To enhance material utilization system survivability, reliability-based optimization is necessary. In this paper, novel (RBDO) method proposed via combination topology, shape, size optimization. innovation includes multi-technology integrated approach new reliability assessment method. Topology, techniques are simultaneously incorporated into to obtain lighter structure. And an advanced...
