动态窗口法（Dynamic window approach）是路径规划方法很重要的一种算法,主要是在速度空间中采样多组速度，并模拟机器人在这些速度下一定时间内的轨迹，在得到多组轨迹后，对这些轨迹进行评价，选出最优轨迹对应的速度来驱动机器人。(Dynamic window approach is an important algorithm for path planning. It mainly sampled multiple groups of velocities in the velocity space and simulated the trajectories of robots in a certain time under these velocities. After obtaining multiple groups of trajectories, the trajectories were evaluated and the optimal trajectories were selected to drive the trajectories.)
