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...
ROS::Time[/Duration/Rate]:ROS时间——来源可以被认为修改如加速/减速/暂停。 ROS::WallTime[WallDuration/WallRate]:ROS绝对时间——不可修改的"真实"时间。 所有的ros::noed在启动时如果有设置[ros::param] \use_sim_time = true则节点的ROS::Time从/clock中获取,否则其值和ROS::WallTime一致。
I may have some time to take a look and propose a fix. Though I wonder if its not more direct to fix this in gazebo_ros2_control by setting use_sim_time=True when gazebo_ros2_control creates the controller_manager? Is there ever a case where you would not want sim_time when using...
This issue will aggregate the work on a ROS Time object in the client libraries (C++ and Python) as well as implementing the simulated time similar to (if not exactly like) roscpp::Time + use_sim_time from ROS 1. There is already a desig...
实际场景中，有很多现象不能单纯的进行定量描述，只能用例如“出现”“不出现”这样的形式进行描述，这种...
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 ...
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 th...
Changing the "use_sim_time" does not seem to affect this, I don't know if I do need to modify something else to change the timestamp of the ros-bridge modules
The issue for me was that ignition gazebo was not publishing to /clock. Adding this to the ros gz bridge config file: - ros_topic_name: '/clock' ros_type_name: 'rosgraph_msgs/msg/Clock' gz_type_name: 'ignition.msgs.Clock'
Projects None yet Milestone No milestone Development Successfully merging a pull request may close this issue. Don't record sim-time messages before first /clock ros2/rosbag2 When using sim time, wait for /clock before beginning recording ros2/rosbag2 4 participants Footer...
