Thanks! This helped.

Haven't gotten to adding the Plugin/Xacro for the laser yet, but for some reason, using the <include> and <uri> tags within <model> of model.sdf of a Pioneer robot does not seem to yield the import of the Hokuyo Laser.

http://sdformat.org/spec?ver=1.6&elem... Following the documentation here, what I'm doing, seems fine. Any help?

<include>
  <uri>model://hokuyo</uri>
     <pose>0.2 0 0.9 0 0 0</pose>
</include>
<joint name="hokuyo_joint" type="revolute">
   <child>hokuyo::link</child>
   <parent>chassis</parent>
   <axis>
     <xyz>0 0 1</xyz>
     <limit>
        <upper>0</upper>
        <lower>0</lower>
     </limit>
  </axis>

Got a Rasberry Pi 3 with a ~16 GB Model 10 SD card. So when deciding between Ubuntu Mate 16.04 and Rasbian, which one should I prefer? Has anyone tried both or either and had a better or worse experience? Thank you.

catkin_package() did the trick for me! Thanks!

I wrote a couple of simple .cpp pub-sub combinations. CMakeLists.txt seems to be fine with all the package dependencies being satisfied, adding executables and linking libraries. The build files are generated and if I go to the build/package_dir and execute my nodes they work fine too!

But rosrun is unable to locate the executables. Everything is sourced (/opt/ros/kinetic and catkin_ws/devel/setup.bash) and ROS_PACKAGE_PATH is also set alright.

Although, just changed my ROS distro from Indigo to Kinetic. Anyone can help with the issue?

I'm working on a laser rangefinder that has an update rate of the order of ~10k and returns one sample. With the documentation provided by the manufacturers, I have the beam pattern chart and the beam divergence at different ranges. Had a word with them today and they were unable to really precisely predict the <min_angle> and <max_angle>.

But I've noticed that when I simulate with 1 sample on Gazebo, the beam does not diverge from the <min_angle> specified. What is the function of <resolution> in that case? And how much should I be setting it for the beam to diverge in Gazebo? http://sdformat.org/spec?ver=1.6&elem... is the documentation.</resolution></min_angle>

Try installing ros-indigo-opencv3 (apt-get)

Despite compiling and installing opencv 3.1.0, I had the same error. But it got fixed after that.

Or else, add LD_LIBRARY PATH as usr/local/bin (if that's where your symbolic link files are stored) to your .bashrc.

In case, nothing works, you should check whether cv2.so exists in your /usr/local/lib/python2.7/site-packages & ../dist-packages directories. If not, you should consider reinstalling opencv again.

Hope this helps!
