By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News – New study results on robotics have been published . According to news originating from Shanghai, People’s Republic of China, by Ne wsRx editors, the research stated, “Intelligent mobile robots have been graduall y used in various fields, including logistics, healthcare, service, and maintena nce.” Funders for this research include Shanghai Sailing Program. The news correspondents obtained a quote from the research from Shanghai Polytec hnic University: “Path planning is a crucial aspect of intelligent mobile robot research, which aims to empower robots to create optimal trajectories within com plex and dynamic environments autonomously. This study introduces an improved A* algorithm to address the challenges faced by the preliminary A* pathfinding alg orithm, which include limited efficiency, inadequate robustness, and excessive n ode traversal. Firstly, the node storage structure is optimized using a minimum heap to decrease node traversal time. In addition, the heuristic function is imp roved by adding an adaptive weight function and a turn penalty function. The ori ginal 8-neighbor is expanded to a 16-neighbor within the search strategy, follow ed by the elimination of invalid search neighbor to refine it into a new 8-neigh bor according to the principle of symmetry, thereby enhancing the directionality of the A* algorithm and improving search efficiency. Furthermore, a bidirection al search mechanism is implemented to further reduce search time.”
