2018-08-17 06:23:23 -0500 | marked best answer | Get only depth data from Kinect using libfreenect Hi, In order to reduce the amount of CPU freenect nodelet is using on my robot I would like to get only the topic "camera/depth_registered/image_raw" cause this is the only one I need right now. In case this is not posible, I would like to know if I can run freenect nodelet remotely. I try but as the camera is not connected to the PC running it I get the message "No devices connected". Is there any way by which I could execute it remotely? And another problem I have is that if I execute "depthimage_to_laserscan" module in the remote PC (after launching freenect in the robot connected to Kinect) it does not work (I do not get any errors or warnings but the /scan topic does not show anything), however, in the robot it does work. Could it be cause one of ROS versions is Kinetic and the other one Indigo? This is the launch file: <launch> <node pkg="depthimage_to_laserscan" type="depthimage_to_laserscan" name="depthima$ <param name=" scan_height"="" value="3"/> <remap from="image" to="camera/depth_registered/image_raw"/> </node> </launch> Thanks in advance. |

When I run AMCL I get constantly the following warning and error: When I launch Rviz and set the initial pose with "2D Pose Estimate", /initialpose topic echo's the following: And in the terminal running AMCL appears: But after that it continues throwing same warning and error mentioned before. I can not attach TF tree, but it is: map -> odom -> base_footprint -> base_link -> ...And TF transformations are working right at a rate, respectively in those cases, (starting with map -> odom) of: 21.609, 42.11, 50.981.
