胡老师好,请教您一个问题。我在跑rrt自主建图仿真。。运行“single_simulate_house launch”文件时,报Deprecated: xacro tag 'kobuki' w/o 'xacro:' xml namespace prefix (will be forbidden in Noetic),这个应该没有什么影响吧?,,最后一直报了一个warning,TF树没有连上:Timed out waiting for transform from robot_1/base_link to robot_1/map to become available before running costmap, tf error: Could not find a connection between 'robot_1/map' and 'robot_1/base_link' because they are not part of the same tree.Tf has two or more unconnected trees.. canTransform returned after 0.1 timeout was 0.1.,
请问时哪里出了问题?
