It's not a solution to this problem. It's a workaround. I tried as @damjan mention but didn't work. Currently, I am visu

Hi there,

I have groovy installed on my ubuntu 12.04. If i install standalone opencv without uninstalling opencv which is installed with groovy, would it be any problem?

Kindest regards Hossain

Did you make your robot autonomous with PR2??

Ok. If i manage to use it then i will share my experience.

Thanks sai for those papers. Looking like that's what i'm looking for. Did you use the OmniMapper??

Hi Silgon, Sounds like we can help each other. I'm trying to make autonomous navigation and mapping with pioneer, odometer and laser. What's your project?

Hi Jaimerv, why the collision? is it because your robots can't detect obstacles or can't take decisions properly??

Thanks sai, I'm using gmapping for a while. Now I need to use line feature based SLAM to compare with my result. I'm going through OMNIMAPPER to see whether it does.

Hi Stefan, Did you use EKF-SLAM (provided by Tim Bailey)? I can use his matlab simulator. I works where features are points. Do you know whether it works with line features instead of the point features?

Thanks stefan. I appreciate your reply. I know about openslam. Those EKF slam are implemented in matlab. FLIRTLib uses image. but i have to use for LASER and I was looking for ROS node or C++ code.

Hi there,

Is there any ROS package for feature/landmark based SLAM that can work with laser and odometry information?

Can you give me any advice?

I appreciate your reply.

Best regards

Hi Chik, did you finish your project. I'm trying to do exactly same. can you help me? I have pioneer 3D-X mobile robot with odometer and laser. Please help me.

Hi there,

Hi ROS-users,

I have some..

Hardware: Pioneer3, SICK-lms200, laptop, 2 usb-serial cables

Software: ros-hydro-desktop-full on laptop running ubuntu-12.04. sicktoolbox(works fine)

Objectives: 1. To control robot by laptop keyboard and log laser data. 2. To build map from that logged data using slam_gmapping.(I know how to achieve objective2)

I can connect my robot and sick laser using rosaria.

Can anyone tell me how can i move my robot using keyboard?

Thanks in advance

Hi everyone,

I managed to run gmapping to build a map from logged data. progress is going on for an hour. sequences i followed

$roscore $rosparam set use_sim_time true $rosrun gmapping slam_gmapping scan:=base_scan $rosbag play

Hi everyone,

Do you know whether TORO - Tree-based netwORk Optimizer ros package available? I downloaded from http://www.openslam.org/toro . It compiles and runs, but couldn't save output as image file. Can you help me to do that?
