2021-07-30 09:26:22 -0500 | marked best answer | DWA Planner path deflects and prevents smooth movement Hi, here's the video. Problem occurs at 0:09 and 0:17. When i give goal to the robot, DWA planner produces local path but, after the robot gains good velocity, it produces a local path which greatly deflects from the global path and causes the robot to slow down and halt for a few moments before continuing. This reduces the performance of the robot. Any suggestions on how to make the movement smooth ? |
