MoveBase expects goal Messages (geometry_msgs/Pose) on topic move_base_simple/goal. The Problem is that the action servers are started after the plugins are loaded, meaning that when mbf gets stuck loading the plugins, it won't start the action servers. It is recommended to run rosdep rosdep install move_base_sequence before building the package to make sure all dependencies are properly installed, note: Using code, the user can send to the navigation stack a desired pose for the robot to reach. This examples allows you to send goals directly from a ROS node. It is calculated by P_MAG_TS. You signed in with another tab or window. Source Project: rosbook Author: osrf File: patrol_fsm.py License: Apache License 2.0. The project is part of another project , aiming at move and navigate a robot(turtlebot in gazebo under this case) without the help of RViz. Implement move_base_sequence with how-to, Q&A, fixes, code snippets. Run Ctrl-C from the previous run_move_base_blank_map . MBF can use existing plugins for move_base, and provides an enhanced version of the planner, controller and recovery plugin ROS interfaces. The server runs through move_base_sequence node, which is initialized in server.py. For ROS2, There is a more suitable controller in Nav2 itself. The task is predefined in task_publisher.py. Use Git or checkout with SVN using the web URL. My task is to bring up the navigation stack in order to do some tests with the planner (that I have chosen). simple navigation goal node is used from link: . rosdep install will fail for eband_local_planner, because the team hasn't released the version for noetic yet. Ok, could you tell me what kind of problem may appear with these nodes because I still don't understand why it doesn't work. A robot using move base sequence can have two states: move_base_simple is not an ActionServer, the move_base developers just chose a similar name. I think there is a problem with your pose estimation node, In a simulation, gazebo publishes odometry and transformation between odom and base_link. Current time: 1466504490.2169, global_pose stamp: 1466504032.8989, tolerance: 0.3000. Let's begin. gazebo + jackal_sim_robot + jackal_sim_mec + jackal_lnav (this contain amcl and move_base) + simple_navigation_goal node. You may also want to check out all available functions/classes of the module move_base_msgs.msg , or try the search function . Can you help?
