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. 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 ...
