2014-09-08 09:21:10 -0500 asked a question use some functions of move_base

Hello! Is there any way to use only some functions of move_base? I want to use in my node only the global costmap created with move_base and nothing else (no planners)

2014-09-07 17:14:46 -0500 commented answer amcl publish frequency map-> odom

Yes I'm using Gazebo. Still 20 hz after modifying update_rate to 30

2014-09-07 04:54:58 -0500 commented answer amcl publish frequency map-> odom

where do I have to modify in order to increase frequency? In the urdf file I have : <sick_laser_v0 name="laser" parent="base" ros_topic="scan" update_rate="30" min_angle="-0.97" max_angle="0.97" l_x="0.5" l_y="0.0" l_z="0.25" l_r="0.0" l_p="0.0" l_yaw="0.0"/> <gazebo reference="laser_link">

yes It works! :)

I'll try and let you know!

2014-09-06 04:38:38 -0500 commented answer amcl odom dynamic obstacles

So with robot pose ekf and laserscan matcher the position will always fail?

2014-09-06 04:14:51 -0500 commented answer How does turtlebot tell if its localization matches its position on rviz?

Yes I have already a map of an empty room created with gmapping. But if I add some obstacles (cubes not moving) in the stage, the robot position will jump around. Should I use laser scan matcher for localization instead of robot pose ekf?

2014-09-06 04:13:06 -0500 commented answer amcl odom dynamic obstacles

I'm using a static map of an empty room created with gmapping. Now I add to the stage some obstacles and trying moving the robot, but it's position will jump around and localization will not be accurated. Any suggestion? Should I use laser scan matcher instead of robot pose ekf?

2014-09-05 12:36:01 -0500 asked a question amcl odom dynamic obstacles

Hello everybody! I have a problem: I'm running amcl and navigation stack on husky in a empty room. If I add some obstacles in the room the global costmap will update but unfortunately the odom frame will have a wrong position. Can somebody help me please? I'm using hydro on ubuntu 12.04lts

I'm interested to this topic too. any news?

2014-09-05 11:25:00 -0500 commented answer How does turtlebot tell if its localization matches its position on rviz?

I'm interested to this topic too. I have the same problem: I have a map of an empty room and I start using AMCL. If I add an obstacle , the global costmap will update, but at the same time the odom frame will be very wrong . How should I do? Do I have to use another package?

2014-09-05 09:12:28 -0500 commented answer amcl publish frequency map-> odom

ok so where do I have to look? In the robot's urdf where is specified the laserscan? Or somewhere else?

2014-09-05 08:57:18 -0500 marked best answer How to refresh automatically global costmap in Rviz

Hello! I'm wondering how to automatically refresh the global costmap visualization on Rviz. The problem is: I have an initial global costmap and I add an obstacle in gazebo. At this point the global costmap in Rviz should update, but it doesn't. Is there any refresh option? I'm sure that at low level the global costmap is updating since if I disable and then enable the global costmap button, Rviz visualize the new costmap.

Hello! in my tf tree I have that between /map and /odom there's amcl that publish at 20Hz. How to increase this speed rate?

yes! There was the default value! I simply changed it to 5.0 and it works! Thanks a lot :)
