Hello everyone!Now i want to use the package "rgbdslam" to get the camera trajectory and the 3d point cloud data,but i do not know where the relative code is in the package "rgbdslam/src" . Furthemore,if i would like to save the camera trajectory and display the camera trajectory on the screen,so how should i do? Thank you very much for your advice! note:Ubuntu 11.10,ROS electric

I need to use the data from kinect,and i have installed the stack openni_kinect;so if i want to get and read the data from kinect,should i need to create a node to publish the relative messages? and how should i create? Or is there another way to complete it? In addition i did not find any information about "publisher" or "service" in the stack openni_kinect. note：Ubuntu11.10 ROS electric Thank you very much!

when i run the command roslaunch rgbdslam rgbdslam.launch it shows the error:

ERROR: cannot launch node of type [rgbdslam/rgbdslam]: Cannot locate node of type [rgbdslam] in package [rgbdslam]

And when run the command "rosmake --rosdep-install rgbdslam" ,showing the error:

In file included from /home/lihaiyang/ros/rgbdslam/external/gicp/bfgs_funcs.cpp:37:0: /home/lihaiyang/ros/rgbdslam/external/gicp/optimize.h:44:28: fatal error： gsl/gsl_linalg.h：not have the file or directory Compiler interrupt make[3]: * [CMakeFiles/gicp.dir/external/gicp/bfgs_funcs.o] error 1 make[3]:leaving the directory /home/lihaiyang/ros/rgbdslam/build' make[2]: *** [CMakeFiles/gicp.dir/all] error 2 make[2]:leaving the directory/home/lihaiyang/ros/rgbdslam/build' make[1]: * [all] error 2 make[1]:leaving the directory `/home/lihaiyang/ros/rgbdslam/build' Thank you very much!!!

The command runs in Ubuntu-VMware workstation,and I have installed the driver of openni_kinect in ubuntu.But the results is 'no devices connected',so how can I do next? Thank you very much!

*ocean@ubuntu:~$ rosrun openni_camera openni_node

I`m a newer to the ROS,and now I want to do the simulation on my computer with the kinect first,and the final purpose is to do navigation with kinect.So I hope anyone can share your precious experiences about how to do navigation with kinect by steps.
The more detailed, the better!

I trully want to know the steps of using ros to accompish the vision navigation with kinect.By the way,now I have a robot but not the one showed on the ros.org.

Thanks very much!!!

When i run the command "rosrun sicktoolbox_wrapper sicklms _port:=/dev/ttyS0" on the Pioneer Powerbot,the terminal shows the error,and i had tried a lot of solutions on the internet,but those did not work.So hope your advice! note:ROS electric ;Ubuntu 11.10

what i download packages:joystick_drivers-1.4.2 control_toolbox teleop_base but after i run "rosmake teleop_base",there is nothing in the "bin" files of the above three packages; and when i run "roslaunch pioneer-joystick.launch",it displays the erro: ERROR: cannot launch node of type [teleop_base/teleop_base]: Cannot locate node of type [teleop_base] in package [teleop_base] So i donot know how to solve it,hope anyone`s advice! Remark:my softwares are Ubuntu 11.10,ros-electric and what does it mean in http://www.ros.org/wiki/ROSARIA/Tutorials/How%20to%20use%20ROSARIA: "Warning: This Section is Deprecated for Electric teleop_base is deprecated in ROS Electric, this won't work.
