you might want to check if your smart phone supports websocket. rosbridge does not work without websocket.

2016-05-07 05:14:30 -0500 answered a question rosbridge_suite: InvalidPackageException: Unable to load the manifest for package rosgraph_msgs.

It looks like rosgraph_msgs is not detect in your ros package path. Make sure that correct ros environment is set in the PC. It cannot find message packages without proper ROS_PACKAGE_PATH setup.

2015-12-09 08:12:33 -0500 asked a question Where can I find a tutorial to guide how to develop local planner for navi stack

Just as question.

Is there any tutorial that guides how to develop local planner for navi stack?

2015-09-02 19:01:50 -0500 answered a question When ever I try to put my turtlebot2(simulated in gazebo) into a namespace the fake laser stops publishing messages on /scan

There is remapping rule in laserscan_nodelet_manager.

<remap from="scan" to="/scan"/>

You may want to remove this.

2015-09-02 18:57:55 -0500 answered a question turtlebot minimal.launch race condition

It might have racing condition in https://github.com/robotics-in-concer... .

However, it waits 60 seconds for the topics to be ready. which should be enough time for turtlebot to be started in most of recent laptops. So I would suggest to try with other laptops. Or increase the timeout in source level.

If you have hydro apps in your android device, you may need to completely remove them.

This problem is related to this issue https://github.com/corot/world_canvas... which has been resolved yesterday. So please update your debs and source, then retry. It should work as of now.

2015-05-12 01:41:12 -0500 commented question [Please][Turtlebot Installation] Error catkin_make

What was the output when you did 'rosdep install --from-paths src -i -y'?

2015-04-14 20:51:39 -0500 answered a question Ajusting Turtlebot Speed in Autonomous Navigation

you may want to check out rqt_reconfigure. move_base, cmd_vel_mux, navigation_smoother these packages support dynamic reconfiguration.

2015-03-15 21:04:46 -0500 commented question rapp manager errors turtlebot minimal.launch

bondpy.py warning is created by http://wiki.ros.org/bondpy . I have confirmed that it does not cause any problem.

2015-03-09 19:15:25 -0500 commented answer How can I run a cpp code to my Kobuki through the temrinal along with ROS in Ubuntu

I would suggest to follow kobuki tutorials to start kobuki and ros tutorial how to write your own node in cpp.

2015-03-09 19:12:59 -0500 commented question Turtlebot doesn't walk in a straight line

Do you use kobuki or create?

2015-03-09 19:08:35 -0500 commented answer can't launch node of type [nodelet/nodelet]

This is weird. 3dsensor.launch does not associate with any kobuki udev rules...

This kobuki script might be helpful to implement backward move.

2015-02-25 19:06:27 -0500 answered a question Problems launching rocon chatter concert inside of a Docker image

It seems like docker does not support avahi-daemon properly. And it causes a problem in zero configuration.

I have proposed a patch to use rocon without zero configuration in https://github.com/robotics-in-concer...

With this patch, you should be able to run chatter concert without zeroconf failure.

Could you explain how did you start the robot? For example, how you set the environment variables.

2014-11-19 23:15:56 -0500 commented answer Can turtlebot_simulator be loaded with a PGM map?

There are no released package in hydro. But you should be able to checkout turtlebot_simulator hydro-devel branch which includes turtlebot_stage. https://github.com/turtlebot/turtlebo...

2014-11-19 00:01:03 -0500 commented question Can turtlebot_simulator be loaded with a PGM map?

Yeah I was curious about this. It would be really nice feature to test sensors and robot logics in simulation.

turtlebot's spec would be helpful

What do you get from lsusb? and how did you start kinect? what's your pc spec?

2014-10-05 02:36:16 -0500 commented question Broken kobuki reference in Indigo Gazebo

kobuki_desktop includes kobuki_gazebo_plugin which generates libgazebo_ros_kobuki.so. Or did you follow turtlebot src installation guide? if you follow http://wiki.ros.org/turtlebot/Tutoria... , you shouldn't have any problem..

2014-09-28 19:56:36 -0500 commented question Turtlebot_apps failed to install when installing source

Does it happen every time you try? Sometimes, github causes a connection problem.

2014-09-28 19:53:29 -0500 commented question Broken kobuki reference in Indigo Gazebo

Did you install kobuki_desktop?

2014-09-04 20:17:09 -0500 answered a question Which way should I choose to broadcast a topic in ROCON?

Either way should work.

You can flip the position_share publisher from robot A to system X, or you can flip position_share subscriber from system X to robot A.

In this case, a position_share subscriber node in the system X will receive position of robot A.
