I'm new user in turtelbot 2;

I have some questions

1- when we use the netbook (basic configurating), it's necessary to connect the netbook with turtelbot2 via usb cable? 2- when we will test some package like RGBDSLAM, it's preinstalled or we must to download in the netbook. 3- when we verify the connection from Turtelbot to ROS master, we get the following error " Unable to communicate with master", then we use ssh, but it still the same error.

Finally, please if you have some videos or tutorials for how to start the turtlbot, can send it.

thanks for your helps.

Hi,

I would like to know how to visualize the clouds as it is done in ROS fuerte, explicitly I would like to now how to change the camera position in the visualizer once I change its position in the reality. I have tried several pcl visualizer function as : resetCameraViewpoint ,resetCamera , setCameraPosition.

Any help will be appreciated.

Thank you !

thanks for your reply, but I'is not what I' am loking for. ^^

Hi; I would to create a 3D map with Kinect, using PCL, I have two point cloud aligned and concatenated but their concatenation contains duplicate point cloud of the same part. How can I delete this duplication without losing data. I really appreciate any kind of help ! Thanks.

Hi; I used the openni function xnUSBSendControl to move the KInect's motor up and down, and now I'm looking to turn that motor in the left and right. Thanks

I have found the openni configuration file and I have set FPS to 1 in depth, image (rgb) and IR, but when I try to use the Kinect with this configuration I get this error: CvCapture_OpenNI::setDepthGeneratorProperty : Device Protocol: Bad Parameter sent ! thanks.

Hi; Thank you for your reply, I will try to change the openni driver configuration and give a feed back asap.

Hi, I would like to know if it's possible to change the number of fps of kinect, i'm getting 30 fps and I would like to get 1 frame par second. Any help will be appreciated. thnx in advance.

Hi, Please I have to cope with the point cloud registration problem. I'm using a Kinect for grabbing rgb and depth map. I have two point clouds that need to be aligned (merge)! Firstly I get the rgb and depth images that I called respectively rgb1,rgb2, depth1 and depth2. After that, from these images I have generated 2 point clouds called point cloud 1 and point cloud 2 , then I projected the first point cloud ( PCL visualizer). Now I need to add the second point cloud. So for that I have done : 1)-Detection / Description keypoint using SURF applied on the rgb iamges 2)- Matching using Flann Matcher and keepin just the good matches (Threshold trick ) I got the homography and fundamental matrix using RANSAC , also I have used the function estimateAffine3D so I can apply one of the matrices on the second cloud to merge it with the first one, but it is not working ! I really appreciate any kind of help ! Thank you ^^
