The difference was about 500 sec (this is why even setting the transform_tolerance value to 10 sec -> the max value, it didn't change anything). Simply clone the repository: You will now be able to navigate in a similar fashion to this: We used Move Base Flex by relaying mb_msgs/MoveBaseAction to mbf_msgs/MoveBaseAction in a standard Move Base goal callback. But didn't write these nodes, I got the robot and these nodes from other ones. A robot using move base sequence can have two states: paused: paused state stops the move base server and stops the sequence server so the robot stays at its place. More details I ran the simulation with the following commands. In your case, the ActionServer name is probably "/move_base" (but look for those other topic names to be sure. Please take a look at my question here. I try to run the move_base node on a real robot. rosdep install will fail for eband_local_planner, because the team hasn't released the version for noetic yet. Look to your tf (rosrun rqt_tf_tree rqt_tf_tree) and node graph (rosrun rqt_graph rqt_graph). The map properties is predefined in plan_service.py. ! Back to results. The subscriber callback simple_goal_cb handles the mbf_msgs.MoveBaseAction ROS Action Client. A goal is created like this: "Relaying move_base_simple/goal pose to mbf", # move base flex ation client relays incoming mb goals to mbf, # move_base simple topic and action server, # move_base_flex get_path and move_base action clients, "Connected to SimpleActionServer 'move_base'", Finally set your Navigation Goal with the. I think you should publish odom transformation from /mugiro_node directly. This is a ROS package that uses a ROS Action server to manage sending multiple goals to the navigation stack (move base action server) on a robot in order to achieve them one after another. The server runs through move_base_sequence node, which is initialized in server.py. On the client side, we simply connect to the Move Base Action Server, and send a goal, which is then relayed in the above function. On the server side, we start a standard Move Base Action Server, and connect a Move Base Flex Action Client to the default Move Base Flex Action Server. Indeed, when I launch the move_base node, I get continuously the unexpected following warning: Moreover, when I run my own C++ node in order to send a goal command, the program stays blocked inside the waitForServer loop, this loop is as follows: I don't understand why it doesn't work and why when I run the move_base node the move_base action server doesn't come up. loginfo ( "Waiting for move_base action server ." # Wait 60 seconds for the action server to become available A ROS Action server that handles communication with move base action server to achieve a list of required goal poses successively. On the client side, we simply connect to the Move Base Action Server, and send a goal, which is then relayed in the above function. In this example, the robot will follow a (rough) circular path around the turtlebot3_gazebo world. operating: operating state means that the sequence server will be sending goals and waiting for move base response. Reference errors after opencv3 installation [closed], move_base/base_local_planner maximum velocity, move_base action server doesn't come up with a real robot, Creative Commons Attribution Share Alike 3.0. In other words, the system will be fully functioning until something causes state to change to paused (e.g. Using code, the user can send to the navigation stack a desired pose for the robot to reach. Hey, mine is /move_base/goal and /move_base_simple/goal, but it is still showing the same error. In particular I use the lidar to get the corners of a wall and my aim is to navigate close to the corner. My problem is that I can't get a subscriber and move_base Action API to work simultaneously.

Source Project: rosbook Author: osrf File: patrol_fsm.py License: Apache License 2.0. lfr. Are you sure you want to create this branch? I think your problem is in your Publissh_odom_TF node (or mugiro_node). move_base_simple is not an ActionServer, the move_base developers just chose a similar name. state_publisher.py is simply designed for testing service call. After synchronizing it, it worked properly. Also you can use roswtf command for looking whats going on. The package is based on turtlebot, full turtlebot package should be installed (including simulation environment). A new window will show up, scroll down this menu unitl you get to, Publish the targeted pose directly without rviz on the topic, Publish the whole targeted set of poses on the topic. This error usually means that move_base is not running, or that the simple_navigation_goal is not configured with the correct action server name for the move_base node. MBF can use existing plugins for move_base, and provides an enhanced version of the planner, controller and recovery plugin ROS interfaces. A powerful feature of the MOVE_BASE package is to automatically avoid obstacles during global planning without affecting the global path. SimpleActionClient ("move_base", MoveBaseAction) rospy. To install the package,clone this repo git clone https://github.com/MarkNaeem/move_base_sequence.git in your catkin workspace, which is usually ~/catkin_ws, and build the package using catkin_make --pkg move_base_sequence, or by just using catkin_make to build the whole workspace. The node is simply based on actionlib of ROS, you can get further infomation at. Normally you will see the robot rotate for a while and then move to a point and go back. The move_base node links together a global and local planner to accomplish its global navigation task. Toggle line numbers. Thanks to Orhangazi44 for helping me, move_base_msgs Author(s): Eitan Marder-Eppstein autogenerated on Sat Dec 28 2013 17:13:58 Why you using /Publish_odom_TF? But, when I try to bring up the navigation stack on a real robot, the move_base action server doesn't come up. The problem was the clocks of my computer and the robot was not synchronized. 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. Then open a new terminal and run.
