Design and Application of 3D Path Planning Model of Agricultural Automatic Robot

The diversification of China's farming environment has led to a low degree of agricultural mechanization. Three-dimensional path planning can enable agricultural machinery to play a role in mountainous and hilly areas. In this paper, a three-dimensional scanner is used to collect position information, and the data is normalized to establish a mathematical space model. In this space model, the ant colony algorithm is used to search for the optimal path. This model provides a technical reference for automatic agricultural picking and positioning in hilly farming.
