Abstract:

Aiming at the shortcomings of ant colony algorithm in robot path planning, this paper proposes a global path planning method of robots based on improved ant colony algorithm. This method delineates the preferred region in the grid map and establishes a new initial pheromone concentration setting model, differentiating the initial pheromone concentration at each point to avoid the blindness of optimization and improving the convergence speed of the algorithm. The experimental results show that the improved ant colony algorithm has significantly higher convergence rate than the traditional algorithm, verifying the effectiveness of the algorithm.
