A method for mobile robot path planning was proposed based on particle swarm optimization and coordination transformation method.Using the grid method polar coordinates and the Cartesian coordinate transformation path environment modeling,the particle swarm optimization algorithm for mobile robot path planning method was established.It was found that the particle swarm optimization algorithm for mobile robot path planning process was actually a Markov chain analysis.The probability theory was applied to study the relationship with the parameters and convergence of mobile robot path planning,and convergence interval of the method with uniform distribution and normal distribution were clarified.Simulation and calculation results show the effectiveness of the algorithms and methods for mobile robot path planning.
