Hello

I am using libpointmatcher package for finding transformation between two 2D pointclouds (Using RPlidar sensor) . But some times it gives me an Error :

"[ERROR] [1514615155.146144153]: ICP failed to converge: "

Please can anyone suggest me in which situation I will be getting this type of an error . Or does it haves any limitation .

2017-02-08 03:26:16 -0600 commented question move_base takes longer time to update the Goal Status why ?

Yes I have checked My Values are : xy_goal_tolerance = 0.02 yaw_goal_tolerance = 0.08 Do this parameter have any relation with status ?

2017-02-08 00:28:44 -0600 asked a question move_base takes longer time to update the Goal Status why ?

Hello

I am doing an experiments on Navigation Stack by referring the Link ( http://wiki.ros.org/navigation ) But While doing experiment I am facing one Issue.

I am using Rtabmap ( Localization ) + visual odometry + move_base ( with teb_local_planner ).

I am sending goal to the move_base by Cpp APIs, The myprogram.cpp( CPP code ) sends 5 goals to the robot one after the other but after reaching each goal the Robot waits for the GOAL STATUS for more than 2 minutes or it takes longer time than this .Please can you suggest me why the Status takes much longer time to update. Is their any parameter in move_base pkg or in the teb_local_planner which affect this ?

Can anyone Suggest.

Can I read ROS .bag file in Reverse order ? If yes then how it can be done. Please can anyone tell me.

2016-09-21 23:44:25 -0600 asked a question Issue while creating a Map using gmapping?

Hello

I am in confusion, what really the issue is in? Please any one can solved it, we urgently needed to solve it.

In my mobile base Robot , we are now at the stage of creating a map using gmapping, but while creating the map I am facing one issue, The issue is When I move my robot using teleop_twist_keyboard the cmd_vel is generated properly and the robot moves smoothly , but when I use RVIZ tool for visualizing it , in that tool for some second the visualization of robot i.e. its movement on the tool is correct but in between it suddenly changes its route or its position automatically even if my robot has no movement.

I have done the analysis of my scan data it is good and also the analysis for my odometry data. When I select the Fixed frame as "odom" it does show this issue.I am facing the issue only when I am trying to create a map i.e when I select my Fixed frame as "map".

Please can anyone suggest why this would be happening, where might be the problem.

2016-08-25 03:52:33 -0600 asked a question My Robot doesn't stops even if cmd_vel is not Published.Why ?

Hello I am using teleop_twist_keyboard to generate cmd_vel ( geometry_msgs/twist). The Robot successfully subscribes this cmd_vel and moves .

I am using A proportional–integral–derivative controller (PID controller) which is a control loop feedback mechanism (controller) for the robot. This loop takes 1 0r 2 seconds to achieve the required generated cmd_vel .

As we knew If I stopped pressing the keys of keyboard then the cmd_vel shouldn't be published and then the robot should also stop moving.

But in my case this doesn't happens means my robot is taking the last value of generated cmd_vel and it never stops.So please can any one suggests why this is happening ? Why the robot doesn't stops ?

2016-08-24 07:20:55 -0600 asked a question Which depth image should we use ?

Hello

I am using Kinect2 camera for our Robot. When I run kinect2_bridge.launch file from kinect2_bridge package it gives this list of topic for depth image :

1)kinect2/hd/image_depth_rect

2)kinect2/qhd/image_depth_rect

3)kinect2/sd/image_depth

4)kinect2/sd/image_depth_rect

Now I am converting depthimage to laserscan data using depthimage_to_laserscan package which subscribe image ( sensor_msgs/Image) topic

So from the above topic list which one should I use as a image topic for depthimage_to_laserscan.Please can anyone suggest me.
