The navigation goal sequence is calculation with a LTL (Linear Temporal Logic) planner from P_MAG_TS. It seems that when you call spin, the challenge is to keep spin going. Prepare the subscriber before the loop and use spinOnce in the loop. Definition at line 191 of file move_base.h. ROS Message / Action Types A service call that can be made when the action is inactive that will return a plan. 6.4. This is used to wake the planner at periodic intervals. Indeed this solved my problem. Since then it has been modified and extended significantly. source devel/setup.bash. Usage example in combination with a waypoint generator node using Gazebo as simulation: Clone this repository into a ROS catkin workspace. # ===== DO NOT MODIFY! Publishes a velocity command of zero to the base. The move_base node implements a SimpleActionServer, an action server with a single goal policy, taking in goals of geometry_msgs/PoseStamped message type. To avoid leaving the user wondering whats happening and if all is going as desired, Actions implement a feedback mechanism, which let the user receive information every now and then.

Definition at line 48 of file move_base.cpp. The package handles everything regarding the goals: receiving, storing, sending, error handling. Using ROS actions is quite handy when you need an asynchronous client/server mechanism. We want the result from the termination, but we wait until the server has finished with the goal. move_baseactionlib actionlibserviceservice To communicate with this node, the SimpleActionClient interface is used. Definition at line 201 of file move_base.h. I will assume that the reader has knowledge about ROS Packages, Nodes, Topics, Messages and Actions. The target_pose is the goal that the navigation stack attempts to achieve. Load the recovery behaviors for the navigation stack from the parameter server. The action server will process the goal and eventually terminate. Using spinOnce may solve this. Definition at line 233 of file move_base.h. move ( goal) i += 1 Definition at line 1120 of file move_base.cpp. The move_base node tries to achieve a desired pose by combining a global and a local motion planners to accomplish a navigation task which includes obstacle avoidance. Clears obstacles within a window around the robot. Essentially, the move_base action accepts goals from clients and attempts to move the robot to the specified position/orientation in the world. # If the result doesn't arrive, assume the Server is not available, # If the python node is executed as main process (sourced directly), # Initializes a rospy node to let the SimpleActionClient publish and subscribe, Sending Goals to the Navigation Stack C++ node tutorial, Sending a sequence of Goals to ROS NavStack with Python. frame_id = 'map' # Set the time stamp to "now" goal. Definition at line 230 of file move_base.h. This post aim is to provide you with an example Python code for sending a goal pose (desired position and orientation) to a robot, in my case a simulated TurtleBot3, exploiting the ROS Navigation Stack. ROS package to send a sequence of navigation goals read from a YAML file to move_base (C++). This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. When this program is running, you can click the 2D Pose Estimate button and the 2D Nav Goal button in RViz, and rviz_click_to_2d.cpp will convert the data to the appropriate format to publish on the /initial_2d and /goal_2d topics. The package handles everything regarding the goals: receiving, storing, sending, error handling etc. It uses the Move base ros package and action client. The move_base ROS Node, is a major component of the navigation stack which allows to configure, run and interact with the latter. now () # Set the goal pose to the i-th waypoint goal. In other words, the system will be fully functioning until something causes state to change to paused (e.g. The goal is passed to move_base, and I see through rviz that a path is generated, but the robot never starts moving. Run Ctrl-C from the previous run_move_base_blank_map .
