Time Stamp a ROS Message Using Current Time in Simulink
WebIn order for a ROS node to use simulation time according to the /clock topic, the /use_sim_time parameter must be set to true before the node is initialized. This can be done in a launchfile or from the command line. If the /use_sim_time parameter is set, the ROS Time API will return time= 0 until it has received a value from the /clock topic. WebDec 2, 2024 · When use_sim_time is enabled, RCL_ROS_TIME type clock will use time source from topic /clock.. But we have to attach the rcrclcpp::Clock(RCL_ROS_TIME) to one ros node(and furthor one executor) to be able subscibe to topic /clock and update simulated time stored in RCL_ROS_TIME clock instance. According to this understanding, we can … i have nothing johnny manuel
