2016-09-21 07:53:38 -0500 | asked a question | Turtlebot doesn't move in Gazebo Hello, I am trying to add different local planner to my ROS navigation stack, eband_local_planner is one among them. I'm using the navfn as global planner and eband as local planner which I downloaded from here. I created a launch file for the stack. The configuration files are taken from here. Once I launch the file Gazebo gives out exact local and global path, however the turtlebot doesn't move in the simulation. I'm also attaching the video link of the process. Can anybody point out the mistake with the process. EDIT #1
Added the rqt_graph here Thanks,
Karthi. |

Is /clock being published?

2016-08-29 08:55:10 -0500 | asked a question | Sbpl_lattice_planner with teb_local_planner in Gazebo simulation. Hello, I'm using the sbpl_lattice as my global planner and teb_local_planner as my local planner in my navigation stack. I'm trying to run and visualize them in Gazebo Simulation environment and with Rviz as well. I created a launch file for that. Im posting it for reference. <!-- -->

2016-08-18 07:58:14 -0500 | asked a question | How do I get the position of the Turtlebot at current time and check if that pose is exactly same to the pose in the plan provided by the planner? I'm using the navigation stack to generate a global plan. Once the plan is generated, I can see the Turtlebot navigating in Gazebo. I need to know how to check the Turtlebot's current position in the map and if it is following the same plan generated by the planner. How can I do this by code. |
