您好,很抱歉再次打擾您!我想請問一下,當我使用阿克曼結構的小車進行導航時,(導航的參數和您貢獻的這個項目的參數一致),我把目標定發布到小車後方,此時導航的terminal顯示無法到達目標點。多次測試發現,dwb無法實現倒車功能,若我需要實現倒車功能的話,是否需要更改導航過程中引用到的某個參數呢?

我記得 DWB 只要 min_vel_x: -1.0 設為負數就可以倒車了, 不確定為何你的車子無法倒車?
請你交叉測試:

  1. NeuronBot simulation 可否倒車?
  2. 你的小車可否使用 teleop_twist_keyboard 倒車?

By the way, Akerman model 的車子,建議使用 TEB 來導航.

這樣是否能看清楚呢?在rviz中未知地圖和已知地圖都是全白的。
