rosparam set use_sim_time true 是一个在ROS(Robot Operating System)中设置参数的命令,具体用于将 /use_sim_time 参数设置为 true。下面我将详细解释这个命令的作用、使用场景以及如何验证其是否成功设置。 1. 作用 仿真时间模式:当 /use_sim_time 设置为 true 时,ROS系统将使用仿真时间而非实际(墙钟)时间...
在ROS_INFO输出的时间戳中可以观察到两者的差异。首先我们设置rosparam set /use_sim_time true 然后启动如下代码 : ROS_INFO("%lf,%lf",(double)(ros::WallTime::now().toSec()), (double)(ros::Time::now().toSec())); 发现输出时间戳前缀没有ROS::Time以为此时/clock未有信息发布,且ROS::Time...

I am trying to setup MoveIt2 with a UR5e in Gazebo Fortress. Everything works well apart from the sensors. I have a depth camera that also publishessensor_msgs/PointCloud2, Since I am running a simulation and the/clocktopic is present, I passeduse_sim_time:=trueto the move group node...
Per discussion in #325 , I have added a few lines to controller_manager.cpp to set the controller node's use_sim_time parameter to match the controller_manager's when it is set to true. An INFO mes...
crabinercommentedNov 8, 2021• edited on ros2 galactic I have set "use_sim_time" to true on my custom panel for rviz but the clock is still machine clock and not simulated time I have tried setting the flag on runtime as well, and in callback loop I always see machine clock ...
The problem is that if the visualization markers are in frame that is not the fixed frame in RViz, RViz tries to find the transform at the current Wall time despite the fact that 'use_sim_time' is true. This fails horribly, of course, and results in a tf extrapolation-into-the-future...
I'm playing back a bag file, using "rosplay -b 100 name.bag". The -b option makes rosplay publish the bag recording time on the /time topic. On the parameter server I set the use_sim_time parameter: $ rosparam get use_sim_time true In the python code I'm running, I want to...
