Therefore, we'll set the header of the message and the child_frame_id accordingly, making sure to use "odom" as the parent coordinate frame and "base_link" as the child coordinate frame.

WebTo fix this, edit your code as shown below (add the last timeout parameter): rclcpp::Time now = this->get_clock()->now(); transformStamped = tf_buffer_->lookupTransform( toFrameRel, fromFrameRel, now, 50ms); The lookupTransform () can take four arguments, where the last one is an optional timeout. It will block for up to that duration waiting ... 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 …

WebJan 11, 2013 · Time represents the ROS 'time' primitive type, which consists of two integers: seconds since epoch and nanoseconds since seconds. Time instances are mutable. The Time.now () factory method can initialize Time to the current ROS time and from_sec () can be used to create a Time instance from the Python's time.time () float seconds … 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.

WebThe time abstraction can be published by one source on the /clock topic. The topic will contain the most up to date time for the ROS system. If a publisher exists for the topic, it will override the system time when using the ROS time abstraction. If /clock is being published, calls to the ROS time abstraction will return the latest time ...
