2014-12-02 03:49:00 -0500	answered a question	hector_localization build error Well, what solved the problem was manually installing two packages from git. Namely geographic_msgs and uuid_msgs. I'm not quite sure why those went missing but now hector_localization compiled. Thanks Dirk!
2014-12-02 03:38:44 -0500	commented answer	Hector Slam input IMU data Ok thanks!

2014-12-01 06:59:14 -0500	asked a question	Hector Slam input IMU data Hi there, I am running hector_slam in ROS Hydro with a Neato XV-11 laser and a Razor 9dof IMU. The IMU has been included via hector_imu_attitude_to_tf. In RViz everything looks good, I have a base_footprint frame that only moves on X and Y (and yaw) and attached to it a base_link frame that has additional roll and pitch movement. Now my question is this: Right now the IMU data is only transforming a frame but I guess that has no direct effect on the computation of hector_slam? Do I have to specify somewhere that hector_slam should consider the IMU data to increase its own accuracy? Or do I have to run an additional node for that, like hector_localization?

2014-11-27 15:23:07 -0500	commented answer	Build of Win_Ros with Visual Studio 2013 for Kinect2 usage oogabooga did you get that to work. I am trying right now but stuck as in the post below. Maybe you can give me a hint? http://answers.ros.org/question/19848...
2014-11-27 15:10:35 -0500	commented answer	no neato laser scan with hector_slam Did you try to remove anything related to RViz in the launch file to see if it starts then? You could then still record a bag and play it afterwards?
2014-11-27 15:07:06 -0500	asked a question	Trying to install Microsoft Kinect v2 driver in ROS Hydro Hi community, I have been trying to install the Kinect v2 drivers following the instructions here. As stated on that page I first need to install libfreenect2 and that is where I am stuck. My system is Ubuntu 12.04 LTS with ROS Hydro. I was running Indigo before but wanted to try out rgbdslam so I downgraded because it did not seem to work in Indigo. Following the README on this page I did the following: Cloned libfreenect2 from git Installed the missing dependencies with "sh install_ubuntu.sh" Checked if I need to fix libturbojpeg but it told me that "/usr/lib/x86_64-linux-gnu/libturbojpeg.so" exists, so I skipped that Then I went on to build protonect. When I executed "cmake CMakeLists.txt" there was an error saying that "libusb.h" could not be found. On my drive I found "libusb.h" in "/usr/include/libusb-1.0/". After copying it to "/usr/include/" cmake did not complain anymore and came out clean. But then when I run "make", it's giving me a headache. Here is the output: tinytron@tinytron:~/libfreenect2/examples/protonect$ make [ 43%] Built target glfw [ 46%] Built target generate_resources_tool [ 48%] Building CXX object CMakeFiles/freenect2.dir/src/usb_control.cpp.o /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp: In function ‘int libfreenect2::protocol::libusb_ext::set_isochronous_delay(libusb_device_handle, int)’: /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp:73:24: error: ‘LIBUSB_SET_ISOCH_DELAY’ was not declared in this scope /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp: In function ‘int libfreenect2::protocol::libusb_ext::set_sel(libusb_device_handle, int, uint8_t, uint8_t, uint8_t, uint8_t)’: /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp:88:24: error: ‘LIBUSB_REQUEST_SET_SEL’ was not declared in this scope /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp: In function ‘int libfreenect2::protocol::libusb_ext::get_max_iso_packet_size(libusb_device, int, int, int)’: /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp:160:13: error: ‘libusb_ss_endpoint_companion_descriptor’ was not declared in this scope /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp:160:54: error: ‘companion_desc’ was not declared in this scope /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp:162:107: error: ‘libusb_get_ss_endpoint_companion_descriptor’ was not declared in this scope /home/tinytron/libfreenect2/examples/protonect/src/usb_control.cpp:168:72: error: ‘libusb_free_ss_endpoint_companion_descriptor’ was not declared in this scope make[2]: [CMakeFiles/freenect2.dir/src/usb_control.cpp.o] Error 1 make[1]: * [CMakeFiles/freenect2.dir/all] Error 2 make: * [all] Error 2 tinytron@tinytron:~/libfreenect2/examples/protonect$ Any idea what's happening? Is it because I am running Ubuntu 12.04? Thanks a bunch. UPDATE:** This issue seems resolved I think it was caused by downloading the wrong git. Stupid copy and paste mistake actually. In the README here it says Download libfreenect2 git clone https://github.com/OpenKinect/libfree... which is the original libfreenect2 package. But you actually need this one: https://github.com/wiedemeyer/libfreenect2.git, which is based off the original but different. Maybe this should be changed. Now I ran into another issue while executing make. Seems like there is a problem with OpenCL: `[ 50%] Building ...` (more)

2014-11-18 10:54:30 -0500	answered a question	no neato laser scan with hector_slam Not sure what the problem is but maybe you want to try my launch file. It's working fine over here with XV-11 and hector_slam. Hmm I cant post it as code because the xml seems to get messed up and I can't upload files yet, so here it is on pastebin: hector_launch Before you run it you just have to start your Neato driver manually, didn't include that yet... Good luck.

2014-10-15 02:05:32 -0500	answered a question	Trying to get the XV-11 Lidar to work Hey ahendrix, thanks for the quick response! I noticed before that connecting the Lidar's Tx to the RS232 Rx did not deliver any data. So I connected Tx to Tx on the RS232 plug, which seems kinda fishy. I ordered a XV-11 controller from GetSurreal now and it's on its way. I'll update this post as soon as I have tested it. Thanks again. EDIT: The issue is resolved and the XV-11 is working beautifully with ROS and hector_slam. There were a couple of things I had to change. First the Serial converter, I am now using a FTDI Breakout from Sparkfun to translate the signal to USB. Obviously these RS-232 converters speak a different language and that messed up the signal. Then I switched the sensor power from 3.3V to 5V. On the inside of the XV-11 on the board it says 5V right next to the power cable. Next I want to add the Razor 9dof IMU to the setup to get some attitude data, will see how that goes...
2014-10-14 17:13:08 -0500	asked a question	Trying to get the XV-11 Lidar to work Hey there! I already asked this over at the Trossen Robotics Forum but did not get a reply yet. Maybe someone here can give me a hint at what might be wrong with my XV-11 Lidar Setup. I bought the laser scanner from Ebay and am trying to get it to work in ROS. What I have done so far: Connected the Lidar to ROS Indigo running Ubuntu in Virtualbox on a Windows Machine. For the power to the motor I am using a 3V regulator that gets its power form USB (5V). The sensor is powered by an Arduino with 3.3V for now. Instead of the Sparkfun FTDI board I am using a standard RS-232 to USB Adapter that is getting its data from the Lidard's Tx. The adapter gets accepted by Ubuntu. Dmesg shows: usb 1-2: FTDI USB Serial Device converter now attached to ttyUSB0 Running rostopic echo /scan I get this: header: seq: 34 stamp: secs: 1413106818 nsecs: 470585788 frame_id: neato_laser angle_min: 0.0 angle_max: 6.28318548203 angle_increment: 0.0174532923847 time_increment: 0.00059940997744 scan_time: 0.0 range_min: 0.0599999986589 range_max: 5.0 ranges: [0.25600001215934753, 8.192000389099121, 4.928999900817871, 13.229000091552734, 13.300999641418457, 13.274999618530273, 10.946999549865723, 0.37700000405311584, 14.380999565124512, 15.883000373840332, 15.381999969482422, 0.25600001215934753, 8.960000038146973, 6.848999977111816, 13.114999771118164, 13.0649995803833, 13.126999855041504, 13.109000205993652, 0.36899998784065247, 14.380999565124512, 15.883000373840332, 15.378000259399414, 0.5120000243186951, 1.2799999713897705, 6.880000114440918, 13.14900016784668, 10.869000434875488, 9.96500015258789, 10.836999893188477, 0.37599998712539673, 14.348999977111816, 15.873000144958496, 15.847999572753906, 16.128000259399414, 11.008000373840332, 6.90500020980835, 11.003000259399414, 10.888999938964844, 10.954999923706055, 4.479000091552734, 0.33799999952316284, 15.279000282287598, 14.972999572753906, 7.293000221252441, 0.23399999737739563, 8.019000053405762, 8.29699993133545, 15.732999801635742, 15.833000183105469, 7.519999980926514, 11.776000022888184, 8.960000038146973, 6.888999938964844, 11.795000076293945, 13.74899959564209, 13.708999633789062, 11.914999961853027, 0.4320000112056732, 11.229000091552734, 16.277000427246094, 16.277000427246094, 9.472000122070312, 8.704000473022461, 3.884999990463257, 16.381999969482422, 16.381999969482422, 16.381999969482422, 16.381999969482422, 8.295999526977539, 15.189000129699707, 16.277000427246094, 13.991999626159668, 9.472000122070312, 0.0, 3.628000020980835, 16.381999969482422, 16.381999969482422, 16.381999969482422, 16.381999969482422, 7.690999984741211, 15.189000129699707, 16.277000427246094, 15.187999725341797, 9.472000122070312, 7.935999870300293, 3.627000093460083, 16.381999969482422, 16.381999969482422, 16.381999969482422, 16.381999969482422, 8.399999618530273, 15.189000129699707, 16.277000427246094, 13.991999626159668, 9.472000122070312, 7.679999828338623, 3.625999927520752, 16.381999969482422, 16.381999969482422, 16.381999969482422, 16.381999969482422, 8.295999526977539, 15.189000129699707, 16.277000427246094, 13.991999626159668, 9.472000122070312, 7.423999786376953, 13.097000122070312, 16.381999969482422, 16.381999969482422, 16.381999969482422, 16.381999969482422, 8.406000137329102, 15.189000129699707, 16.277000427246094, 16.37700080871582, 15.871999740600586, 11.520000457763672, 14.026000022888184, 16.381999969482422, 16.381999969482422, 16.381999969482422, 16.381999969482422, 0.43700000643730164, 16.35700035095215, 16.37700080871582, 16.356000900268555, 15.871999740600586, 4.0960001945495605, 14.001999855041504, 16.381999969482422, 16.381999969482422, 16.381999969482422, 16.381999969482422, 0.43700000643730164, 16.047000885009766, 16.37700080871582, 16.327999114990234, 15.871999740600586, 8.192000389099121, and so on...
