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...
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 : ...
调整Gazebo参数real_time_factor的方法: 在Gazebo的world.model的文件中,设置仿真运行速率 real_time_update_rate:每秒期望迭代次数(实际受到计算资源的约束,可能达不到) max_step_size:迭代时间步长 real_time_factor:与实际时间的比率 (为real_time_update_rate * max_step_size) ,大于1则比实际时间运行的快 ...
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...
I am trying to use the "camera_segmentation" to be able to modify it and use but I need that this topic published with the system time instead that using the simulation time. Changing the "use_sim_time" does not seem to affect this, I don't know if I do need to modify something ...
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...
