Path planning for agricultural robots based on improved sparrow search algorithm
An improved sparrow search algorithm,SSAPSO,is proposed to address the problems of poor search results and low search stability in path planning for agricultural robots.Firstly,Cubic chaotic mapping is used to initialize the population to enhance the diversity of sparrow population locations.Then,a firefly perturbation strategy is used to increase the flexibility and search range of the algorithm.Finally,particle swarm techniques are introduced to improve the search accuracy and stability.The experimental results show that SSAPSO can solve the optimal path of agricultural robots efficiently and stably in a raster map environment with different obstacle coverage,thus improving the efficiency of agricultural robots.
