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...
一些在Debug中额外的发现: 当将use_sim_timer置为true后,ROS将通过话题/clock获取当前时间。我们可以通过修改仿真速率或是话题的发布频率来设置ROS收到的时间的分辨率,以此保证ROS的timer callback的行为符合预期。 举一个例子:如果在ROS中存在一个 20Hz 的 timer callback,则时间分辨率要至少为 0.05s。如果仿真时间...
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。 观察现象: 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 : ...
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 Gazebo? Then a small addition to spawner.py could allow the...
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...
