Still waiting for valid time... 表现出的现象是:暂停了,并没有进行数据的录制。解决方案如下: #录制前 $ rosparam set /use_sim_time false #播放时 $ rosparam set /use_sim_time true版权声明:本文为JIEJINQUANIL原创文章,遵循 CC 4.0 BY-SA 版权协议,转载请附上原文出处链接和本声明。 本文链接:...
为了解决这一问题,可以让系统以 msg 对应的 simulated time 运行,而不是实际的 wall-clock time. 步骤如下: 启动ROSmaster roscore指定系统以simulated time运行rosparam set /use_sim_time true官方的解释如下:This basically tells nodes on startup to use simulated time (ticked here by rosbag) instead of...
