WebDec 20, 2024 · Although DWA algorithm can generate a collision-free path, the dynamic obstacles are regarded as static obstacles. Therefore, DWA performs poorly in dynamic environments. A novel approach based on DWA considering the velocity of the obstacles is proposed in this section. The DWA algorithm is described as Algorithm 2. In robotics motion planning, the dynamic window approach is an online collision avoidance strategy for mobile robots developed by Dieter Fox, Wolfram Burgard, and Sebastian Thrun in 1997. Unlike other avoidance methods, the dynamic window approach is derived directly from the dynamics of the robot, and is especially designed to deal with the constraints imposed by limited velocities and accelerations of the robot.
