In view of the existing situation that 2D simulation of the underwater robot lacks effective algorithms and strategies when heading the ball in the 1vs1 game, put forwards a method based on mathematical modeling and regional division. Besides, a new region-based strategy that can help head the ball adaptively is introduced in the paper: When heading the ball, the venue is divided into several regions. Different strategies can be adaptively applied to different areas by defining finite automation in the algorithm. The results confirmed that the optimized algorithms and the strategies of regional division are able to help achieve goals more quickly and effectively in the game. In addition, the article makes the existing platform some optimized tips.
