It is calculated by, move_acton_service.py is a ROS service synthesizing the pose sequence and linking the sequence with move_base action server. Please follow. I followed the tutorial of SendingSimpleGoals, and turned it into the Action API while commenting out . A ROS Action server that handles communication with move base action server to achieve a list of required goal poses successively. lfr. Moreover, when I run my own C++ node in order to send a goal command, the program . Thanks for answering. In your case, the ActionServer name is probably "/move_base" (but look for those other topic names to be sure. Using code, the user can send to the navigation stack a desired pose for the robot to reach. In other words, the system will be fully functioning until something causes state to change to paused (e.g. When I run it in simulation (with another robot), it works successfully. operating: operating state means that the sequence server will be sending goals and waiting for move base response. We then relay the goal in the callback of the Move Base Action Server, like in the first subriber callback example. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. 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 package is based on turtlebot, full turtlebot package should be installed (including simulation environment). operating: operating state means that the sequence server will be sending goals and waiting for move base response. 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. move_base_sequence | #Robotics | ROS Action server that handles communication by MarkNaeem Python Updated: 11 months ago - Current License: MIT. sign in The subscriber callback simple_goal_cb handles the mbf_msgs.MoveBaseAction ROS Action Client. client = actionlib.

The seconds parameter tells the SMACH which action server to use to receive a path: /move_base_flex/get_path with the mbf_msgs/GetPathAction we already know from the beginner tutorials. 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. 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. 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. Please take a look at my question here. The following code can be found in actionlib_tutorials repository, and implements a simple python action client for the fibonacci action. Are you sure you want to create this branch? The ROS Navigation Stack takes on the role of driving the mobile base to move to that goal pose, avoiding obstacles and combining all the available informations. Ah ok, thanks. Use Git or checkout with SVN using the web URL. But, when I try to bring up the navigation stack on a real robot, the move_base action server doesn't come up. Because this is so simple (in principle), we will relay Move Base Messages to Move Base Flex and let Move Base Flex take over planning. If you have failed in running test code in P_MAG_TS, please use 1.x version of networkx. It exposes action servers for planning, controlling and recovering, providing detailed information of the current state and the .
