试过了killall gzserver
killall gzclient 问题也没有得到解决。
用rqt 把urdf模型导入的时候报错信息如下:
[Err] [Model.cc:123] Error Code 23 Msg: FrameAttachedToGraph error, Non-LINK vertex with name [model] is disconnected; it should have 1 outgoing edge in MODEL attached_to graph.
[Err] [Model.cc:123] Error Code 23 Msg: Graph with model scope has sink vertex named [model] when starting from vertex with name [model], which is not permitted.
看内容好像是模型 问题,但是我用《动手学ROS2》里面的urdf也不行。
打开gazebo就有警告,但是看网上说这个警告内容无伤大雅
Warning: Deleting a connection right after creation. Make sure to save the ConnectionPtr from a Connect call
(这个问题百度了好多天也没解决,本来打算跳过仿真直接学下面的了,,感觉跳不过去)
真的挺苦恼的,希望可以得到指教
